Clean Cookstoves: An Urgent Necessity

Globally, three billion people in the developing nations are solely dependent on burning firewood, crop residues, animal manure etc for preparing their daily meals on open fires, mud or clay stoves or simply on three rocks strategically placed to balance a cooking vessel.  The temperature of these fires are lower and produce inefficient burning that results in black carbon and other short-lived but high impact pollutants.

These short-lived pollutants not only affect the persons in the immediate area but also contribute much harmful gases more potent than carbon dioxide and methane. For the people in the immediate area, their health is severely hampered as this indoor or domestic air pollution results in significantly higher risks of pneumonia and chronic bronchitis.

To remedy the indoor air pollution (IAP) and health-related issues as well as the environmental pollution in the developing world, clean cookstoves are the way to advance. But to empower rural users to embrace the advanced cookstoves, and achieve sustainable success requires a level of socio-cultural and economic awareness that is related directly to this marginalized group. The solution needs to be appropriate for the style of cooking of the group which means one stove model will not suit or meet the needs and requirements of all developing nation people groups.

Clean cookstoves can significantly reduce health problems caused by indoor air pollution in rural areas

Consideration for such issues as stove top and front loading stove cooking, single pot and double pot cooking, size of the typical cooking vessel and the style of cooking are all pieces of information needed to complete the picture.  Historically, natural draft systems were devised to aid the combustion or burning of the fuels, however, forced draft stoves tend to burn cleaner with better health and environmental benefits. Regardless of cookstove design, the components need to be either made locally or at least available locally so that the long term life of the stove is maintainable and so sustainable.

Now, if the cookstove unit can by powered by  simple solar or biomass system, this will change the whole nature of the life style and domestic duties of the chief cook and the young siblings who are typically charged with collecting the natural firewood to meet the cooking requirement.

Therefore the cookstoves need to be designed and adapted for the people group and their traditional cooking habits, and not in the reverse order. To assess the overall performance of the green cooking stoves requires simple but effective measures of the air quality. The two elements that need to be measured are the black carbon emissions and the temperature of the cooking device.  This can be achieved by miniature aerosol samplers and temperature sensors. The data collected needs to be transmitted in real-time via mobile phones for verification of performance rates.  This is to provide verifiable data in a cost effective monitoring process.

5 Tips for Adding Solar Panels to Your Home

Solar panels are technological appliances that generate electricity by converting light energy into direct currents which are applicable for commercial and residential purposes. The advent of solar panels is a major progress in technology, providing the world with a more economically sustainable and reliable power supply for all possible applications. It also savages the situation of spending extra money on energy bills which can be high, depending on the amount of energy consumed.

In recent times, the installation of solar panels to homes has been a prominent activity of homeowners, especially in the United States. Adding solar panels to your home will not only boost the value of your home, but also give room for savings, and provide a safe and healthy environment. But yet, so many people shun the prospect of installation because it seems like a formidable task.

Today, the addition of solar panels to your home is not a big deal as it was, as the choice of system size, component selection, and mounting and appropriate safety disconnection can be achieved with proper information and knowledge.

These are five tips that you will need to successfully power your homes with solar panels:

  1. Budget

Although there has been a common misconception that solar panel installation is expensive, it is indeed an incredible way of saving money. It helps in minimizing the rate at which you depend on electricity from the power grid, resulting in you saving money in the long run. Even though the initial expenses during the first installation might seem much, it becomes a cost-saving electricity generating facility over time.

Over time, the cost of procuring solar panels is consistently dropping since many people are installing it because is one of the cheapest forms of electricity worldwide. Nevertheless, your financing options is an important thing to consider before anything else – the more financially buoyant you are, the more the utility that will be derived from it. Estimate how much cost that the procurement and the installation of the entire solar set up will incur. The strength of the panels affects the price – the more powerful it is, the more expensive each panel will be.

  1. Roof Condition and Position

Solar panels are very durable and they can have a lifespan of 25 years or more. Considering the longevity of most roofing materials that are affected by some environmental conditions like snow, hail, rain, hurricane, and sunshine, most home roofs don’t last more than 20 years especially most asphalt shingle or composition roofs. So, the condition of the roof of your home must be in the best condition before setting up solar panels.

In addition to the age and condition of your home roof, the positioning in terms of the layout and the direction that it’s facing should be considered. It should be in such a way that sunlight shines on it daily so as to be able to reap all the amazing benefits that exist with going solar if your home qualifies.

If for the most part of the year, your roof is exposed to a considerably significant quantity of sunlight, installing solar panels would be an excellent idea. The more sunlight that is shining on your solar panel is, the more the energy produced. The presence of huge trees around your roof will cast shades enormously, therefore depriving the panels of direct exposure and also of maximizing the energy coming from the sun. When panels are being installed, they should be fixed in such a way that will prevent the accumulation of dirt and debris that could hinder the hitting of the panel by enough sunlight exposure.

Both factors ensure the longevity of an economically stable power supply from the solar panels in your homes.

  1. Activities undertaken in homes

The nature of activities done in the home greatly affects the energy consumption rate. The monthly energy consumption rate of your household may differ in a year due to the fact that you will need to run activities and appliances because of the peculiarity of the season. For example, your electricity bill might be higher in summer months than other months in a year because you will probably run the air conditioner more in this season.

If the energy consumption rate is less, then an undersized solar setup will be sufficient and conversely. An estimate of the number of solar panels that will enough to meet your electricity consumption daily, monthly or yearly should be done appropriately.

So, the knowledge of your home energy consumption rate and your home dimensions allows momentum solar experts to help you design solar systems that best suits your energy use and budget.

  1. Types of Solar Panels

There are different solar panel types based on functions. In the market, the two most sought after solar setups available are:

  • Photovoltaic – which converts sunlight into light energy by using arrays of cells
  • Thermal – which heats up water or air with energy from the sunlight.

So, your choice can be made between the two solar technologies depending on your intended purpose.

According to make-up, solar panels are distinctly grouped into two major categories:

  • Monocrystalline
  • Polycrystalline

Each option should be examined carefully, not forgetting to measure how efficient the solar panel is going to be and the right fit for you.

  1. Warranty Details

Solar panels that are installed in homes have chances of performing efficiently and hassle-free for years. Solar panels can last for as long as twenty-five years under normal conditions. Nevertheless, in rare situations, issues can occur. That’s more of a reason why you should make your buy from a dependable buyer in order to ensure a money-back guarantee and be assured of a lengthy time of performance without breaking down.

Purchasing the right solar panels for your home enables you to enjoy the numerous benefits that come with it. So, do go for a solar panel that suits your home best rather than going for the current fads of the market.

Biomass Energy Potential in Philippines

The Philippines has abundant supplies of biomass energy resources in the form of agricultural crop residues, forest residues, animal wastes, agro-industrial wastes, municipal solid wastes and aquatic biomass. The most common agricultural wastes are rice hull, bagasse, cane trash, coconut shell/husk and coconut coir. The use of crop residues as biofuels is increasing in the Philippines as fossil fuel prices continue to rise. Rice hull is perhaps the most important, underdeveloped biomass resource that could be fully utilized in a sustainable manner.

At present, biomass technologies utilized in the country vary from the use of bagasse as boiler fuel for cogeneration, rice/coconut husks dryers for crop drying, biomass gasifiers for mechanical and electrical applications, fuelwood and agricultural wastes for oven, kiln, furnace and cook-stoves for cooking and heating purposes. Biomass technologies represent the largest installations in the Philippines in comparison with the other renewable energy, energy efficiency and greenhouse gas abatement technologies.

Biomass energy plays a vital role in the nation’s energy supply. Nearly 30 percent of the energy for the 80 million people living in the Philippines comes from biomass, mainly used for household cooking by the rural poor. Biomass energy application accounts for around 15 percent of the primary energy use in the Philippines. The resources available in the Philippines can generate biomass projects with a potential capacity of more than 200 MW.

Almost 73 percent of this biomass use is traced to the cooking needs of the residential sector while industrial and commercial applications accounts for the rest. 92 percent of the biomass industrial use is traced to boiler fuel applications for power and steam generation followed by commercial applications like drying, ceramic processing and metal production. Commercial baking and cooking applications account for 1.3 percent of its use.

The EC-ASEAN COGEN Programme estimated that the volume of residues from rice, coconut, palm oil, sugar and wood industries is 16 million tons per year. Bagasse, coconut husks and shell can account for at least 12 percent of total national energy supply. The World Bank-Energy Sector Management Assistance Program estimated that residues from sugar, rice and coconut could produce 90 MW, 40 MW, and 20 MW, respectively.

The development of crop trash recovery systems, improvement of agro-forestry systems, introduction of latest energy conversion technologies and development of biomass supply chain can play a major role in biomass energy development in the Philippines. The Philippines is among the most vulnerable nations to climatic instability and experiences some of the largest crop losses due to unexpected climatic events. The country has strong self-interest in the advancement of clean energy technologies, and has the potential to become a role model for other developing nations on account of its broad portfolio of biomass energy resources and its potential to assist in rural development.

What is the True Cost of Sustainable Living in the US?

Protecting the environment is something most Americans are passionate about. In fact, a recent study found that over 65 percent of Americans would be willing to make drastic changes to protect the Earth. For years, people have searched for a way to live a more sustainable life.

While this can be beneficial, sustainable living is not cheap. Getting all of the different eco-friendly systems in place can be quite expensive. Properly preparing for your path to a sustainable life can help you avoid biting off more than you can chew financially.

Planting more trees and vegetation will go a long way in reducing heat in urban settings.

The following are some of the things you need to know about the true cost of sustainable living.

A Sustainable Lifestyle Starts With Rethinking Your Power Supply

Most homeowners spend about 55 percent of their utility bills on electricity. Lowering these costs can be easy when using a website like Texaselectricityplans.com, but in order to make your power supply sustainable, you will have to make some changes.

Using solar power can be cost-effective over time, but initially, it will be a bit expensive. Getting a 24-volt solar power system with a backup generator will cost you around $40,000. As this technology is perfected and mass-produced, these initial costs will continue to decline.

Using the Power of Wind Turbines

Another popular power option for people who are trying to live a sustainable existence is wind turbines. While you can’t use this technology solely to power your home, they can be used as a backup to the solar system you have in place.

These systems are great to have, but they can be pricey. The typical wind turbine system will be around $11,000. If you are going to go completely solar-powered, you definitely need to consider including this backup to ensure your lights and appliances stay powered.

Revamping Your Water and Septic Solutions

Once you have your power problems figured out, finding a better way to get water and dispose of waste should be at the top of your list. If you are looking for a way to reduce your dependence on water treatment facilities for drinking water, then utilizing the power of a well is a good idea. Studies show that nearly 15 percent of Americans are using wells for their home drinking water.

If you are using your city’s sewer system to dispose of waste, you need to think about getting a standalone septic tank installed. Getting a well and a septic tank installed will cost around $13,000. There are greywater systems on the market, as well as waterless composting toilets. These systems take some getting used to but are a great eco-friendly waste disposal option.

Establishing an Independent Heating Source

Staying warm in the winter is something everyone views as a priority. Traditional HVAC systems use a lot of energy, which is why you need to establish an independent heating source if you want to live sustainably. One of the best ways to do this is by using wood-burning stoves or propane heaters.

Since wood is a renewable source of energy, you can use it as much as you want in your sustainable life. Buying a wood stove and lumber to keep it going will cost you around $4,000. This is a good deal when you figure out how much you pay in electricity costs during the winter and how much of a strain this puts on the environment.

Creating a Sustainable Lifestyle Takes Time

The journey to a sustainable life will not be easy. The amount of hard work and effort you put into converting your home into an eco-friendly paradise will be well worth it in the long run.

Share of Renewables in Energy Supply of UK

The Earth is facing a climate crisis, as the burning of fossil fuels to generate electricity and power our cars overloads the atmosphere with carbon dioxide, causing a dangerous atmospheric imbalance that’s raising global temperatures.

A report from the UN’s Intergovernmental Panel on Climate Change (IPCC) released earlier this month cautioned that the planet has just 12 years to dramatically curb greenhouse gas emissions, by overhauling our energy systems and economies and likely, our societies and political systems. Even a half degree rise beyond that would cause catastrophic sea level rises, droughts, heat, hunger, and poverty, spelling disaster for our species.

UK’s Commitment to Climate Change Mitigation

The UK government has committed to reducing carbon emissions by 80% of 1990 levels by 2050, a process that will involve overhauling our energy supply, which is responsible for 25% of greenhouse emissions in the country, just behind transport (26% of all emissions). But it may be too little too late. The government has already said it is reviewing these targets in light of the IPCC report and in the spring began consulting on a net-zero carbon emissions target for 2050.

But despite these dire prognoses and the enormity of the task facing us as a species, there’s reason to be optimistic. The UK has already managed to cut greenhouse gas emissions by 43% on 1990 levels, with much of the reduction coming from a 57% decline in emissions from energy generation. This is in part thanks to several providers offering you the chance to have a 100% renewable domestic energy supply.

Reduction in Coal Usage

The use of coal has plunged nearly overnight in the UK. In 2012, 42% of the UK’s electricity demand was met by coal. Just six years later, in the second quarter of 2018, that figure had fallen to just 1.6%. Emissions from coal-fired power stations fell from 129 million tonnes of CO2 to just 19 million tonnes over the same period.

A coal-free Britain is already on the horizon. In April 2017, the UK logged its first coal-free day since the Industrial Revolution; this past April we extended the run to 76 consecutive hours. In fact, in the second quarter of 2018, all the UK’s coal power stations were offline for a total of 812 hours, or 37% of the time. That’s more coal free hours than were recorded in 2016 and 2017 combined and in just three months.

When the UK does rely on coal power, it’s primarily to balance supplies and to meet demand overnight and during cold snaps, such as during the Beast from the East storm in March. The UK is so certain that coal is a technology of the past, that the government has plans to mothball all seven remaining coal-fired power stations by 2025.

Share of Renewables in Energy Supply

The decline in coal has been matched by an explosion in renewable energy, particularly in wind power. In the second quarter of 2018, renewables generated 31.7% of the UK’s electricity, up from under 9% in 2011. Of those, wind power produced 13.3% of all electricity (7.1% from onshore turbines farms and 6.2% from offshore wind farms), biomass energy contributed another 11% of the UK’s electricity, solar generated 6% and hydro power made up the rest of renewables’ pie share.

The UK’s total installed renewables capacity has exploded, hitting 42.2GW in the second quarter of 2018, up from under 10GW in 2010. That includes 13.7GW of onshore wind capacity and 7.8GW of offshore wind capacity—a figure which will get a boost with the opening in September of the world’s largest wind farm, the Walney Extension, off the coast of Cumbria, itself with a capacity of nearly 0.7GW. Solar panels contributed another 13GW of renewable capacity, and installed plant biomass infrastructure reaching 3.3GW.

However, while renewables are transforming electricity generation in the UK, our energy system consists of more than simply electricity. We also have to account for natural gas and the use of fuel in transport, and renewables have made fewer in roads in those sectors.

The UK is meeting just 9.3% of its total energy needs from renewable sources, short of the 15% it has earmarked for 2020 and far behind its peers in the EU, where Sweden is already running on 53.8% renewable energy.

Conclusion

Emissions are dropping overall in the UK, largely due to an ongoing revolution in electricity generation and a decisive move away from coal. But these reductions have concealed stagnant and even increasing levels of greenhouse gas emissions from other sectors, including transport and agriculture.

Our transition to a sustainable economy has begun but will require more than wind farms and the shuttering of coal-fired power stations. It must encompass electric vehicles, transformed industries, and ultimately changing attitudes toward energy and the environment and our responsibility toward it.

Renewable Energy is the Future for Humanity and This is Already a Trend

Throughout the entire contemporary age, human beings have been using fossil fuels to meet their energy needs and requirements. Natural gas, oil, and coal have made it possible for people to receive power in their homes as well as power machinery for many years, thereby pushing civilization forward. However, human development has undergone a steady acceleration, thereby making the unsustainability of such energy ostensible or apparent. There was deterioration of global fuel supplies which have had a major contribution in polluting the atmosphere. So, to guarantee a sustainable future, the search of renewable energy sources took effect.

The civilization of today stands at a precarious moment. People are on the verge of embracing clean energy at a level which has never been seen before. However, before people choose to adopt clean energy and renewable power continuing its hasty advancement, right decisions have to be undertaken. By the stats of essayzoo.org, the introduction of clean energy in the worldwide scenario has raised questions regarding its stability and scalability. Unsteady guidelines and procedures for influencing future growth at a macro level underwent exacerbation because of lack of funding and technological immaturity. Nevertheless, there has been a vast growth and development of clean energy installations, irrespective of the slow pace, until a histrionic hike some few years ago.

The cost of alternative energy systems has dropped sharply in recent years

Today, a significant proportion of the globe’s electricity comes from renewable energy. Many countries have thus set up sheer volume installation targets to ensure they reduce the causes of pollution in their environment. Embracing various types of clean, renewable energy such as solar power, hydropower, and wind power help lessen the causes of pollution in a particular region. Thus, it is advisable that as many countries as possible choose to adopt renewable energy trends and get to enjoy and benefit from its merits.

Renewable energy is a warranty for human survival

As aforementioned, renewable energy helps reduce cases of pollution in an area. Traditional sources of energy such as kerosene lamps and diesel-run generators, cause air pollution as they generate huge volumes of pollutants, thereby creating poor air quality. This can lead to respiratory conditions among people as well as early deaths. However, renewable energy provides an ecological alternative. Also, industries emit gases which pollute the air, thereby putting human life at risk. But, renewable energy helps improve the situation.

Renewable sources of energy such as wind power, geothermal power, and solar power enable people from different communities to utilize natural resources in the production of green, clean energy. Hence, this enables people to manage their energy in an independent manner.

Renewable energy also helps reduce global warming. Human activities overload the air with carbon dioxide and other emissions from global warming. Renewable energy does not produce global warming emissions, albeit the processes it undergoes to produce clean energy. Hence, this helps keep the atmosphere clean and does not put the lives of many people at risk.

Renewable energy is also a warranty for human survival as it helps generate job opportunities for many people and other economic benefits. Renewable energy industries are more labor demanding, unlike fossil fuel technologies. Solar panels involve human beings for installation. Also, wind farms entail technicians for efficient maintenance. Hence, this implies that there is the creation of jobs during the generation of each electricity unit from renewable sources of energy.

Clean, renewable energy can improve the future

The future of clean energy shows a better environment and living conditions for many people. Human beings will not have to rely on other sources of energy to get their activities running. They will not have to ensure certain types of ailments, such as heart disease, cancer, and bronchitis, among other health conditions. Adopting renewable energy helps minimize the likelihood of these disorders happening.

Additionally, they will be able to create job opportunities for themselves when they embrace renewable energy rather than rely on fossil fuels for energy. Fossil fuels are not only capital intensive but also mechanical. Human beings will have to spend a lot of money on such a form of energy. Also, it does not require much of their effort to be put to use. On the other hand, renewable energy requires a lot of labor. There are various solar panels which require installation and wind farms which need maintenance from professional technicians. Thus, adopting renewable energy helps them to have jobs which can generate some income for them, thereby helping them to improve their living conditions.

Solar panels are becoming more accessible, for homeowners and businesses

Clean energy is also ideal for the future in that it helps reduce global warming. Human activities contribute to the overloading of the air with carbon dioxide and other discharges from global warming. But, renewable energy industries do not produce any global warming emissions. Hence, this makes the atmosphere safe and conducive for people to live in. It does not expose them to certain health conditions. Thus, they do not have to worry about their health now and then when using renewable energy.

Main types of clean, renewable energy

The energy trend shows that renewable energy is the future for humanity. Hence, this has had a major contribution in the discovery of various types of renewable energy. Some of them are as follows.

Geothermal energy

The production of this energy comes through the drilling of geothermal systems into the earth’s crust to reach deeper resources of geothermal power, thereby allowing broad access to geothermal energy. Geothermal plants are different in relation to the type of technology they use to cool and the one they use to transform the resource to electricity.

Wind power

Channeling power from the wind is one of the most maintainable and hygienic methods to generate electricity. This is because it does produce any global warming discharges or toxic pollution. Additionally, the wind is affordable, infinite, and profuse. Hence, this makes it a feasible and all-encompassing substitute for fossil fuels.

Solar power

Same to wind power, the sun offers a remarkable resource for generating fresh and maintainable energy.

Hydroelectric power

Hydroelectric power incorporates small run-of-the-river plants and massive hydroelectric dams. Increasing capacity at these dams and river projects help generate some energy.

Nowadays the question of renewable energy is heard more and more often. It’s getting closer to us. Research work is being conducted in universities, students are preparing dissertations on this subject and even third part services can write your dissertation paper in short time with no compromise in quality. So the future of renewable energy shows to be promising. People will no longer have to rely on fossil fuels to get energy. They can embrace the utilization of renewable sources of energy, such as hydroelectric power, wind power, solar power, and geothermal power.

Furthermore, this proves to be a guarantee for human survival on the basis of the points above. Adopting renewable energy is an ideal choice many people and nations need to embrace. Moreover, this will help them identify and recognize renewable energy developments and how they can adopt them in their day-to-day activities hence improving their living conditions.

Food Waste Management and Anaerobic Digestion

Food waste is one of the single largest constituent of municipal solid waste stream. In a typical landfill, food waste is one of the largest incoming waste streams and responsible for the generation of high amounts of methane. Diversion of food waste from landfills can provide significant contribution towards climate change mitigation, apart from generating revenues and creating employment opportunities.

food-waste-biogas

Of the different types of organic wastes available, food waste holds the highest potential in terms of economic exploitation as it contains high amount of carbon and can be efficiently converted into biogas and organic fertilizer. Food waste can either be utilized as a single substrate in a biogas plant, or can be co-digested with organic wastes like cow manure, poultry litter, sewage, crop residues, abattoir wastes etc or can be disposed in dedicated food waste disposers (FWDs). Rising energy prices and increasing environmental concerns makes it more important to harness clean energy from food wastes.

Anaerobic Digestion of Food Wastes

Anaerobic digestion is the most important method for the treatment of food waste because of its techno-economic viability and environmental sustainability. The use of anaerobic digestion technology generates biogas and preserves the nutrients which are recycled back to the agricultural land in the form of slurry or solid fertilizer. The relevance of biogas technology lies in the fact that it makes the best possible utilization of food wastes as a renewable source of clean energy.

A biogas plant is a decentralized energy system, which can lead to self-sufficiency in heat and power needs, and at the same time reduces environmental pollution. Thus, the benefits of anaerobic digestion of food waste includes climate change mitigation, economic benefits and landfill diversion opportunities.

Anaerobic digestion has been successfully used in several European and Asian countries to stabilize food wastes, and to provide beneficial end-products. Sweden, Austria, Denmark, Germany and England have led the way in developing new advanced biogas technologies and setting up new projects for conversion of food waste into energy.

Codigestion at Wastewater Treatment Facilities

Anaerobic digestion of sewage sludge is wastewater treatment facilities is a common practice worldwide. Food waste can be codigested with sewage sludge if there is excess capacity in the anaerobic digesters. An excess capacity at a wastewater treatment facility can occur when urban development is overestimated or when large industries leave the area.

anaerobic_digestion_plant

By incorporating food waste, wastewater treatment facilities can have significant cost savings due to tipping fee for accepting the food waste and increasing energy production. Wastewater treatment plants are usually located in urban areas which make it cost-effective to transport food waste to the facility. This trend is catching up fast and such plants are already in operation in several Western countries.

The main wastewater treatment plant in East Bay Municipal Utility District (EBMUD), Oakland (California) was the first sewage treatment facility in the USA to convert post-consumer food scraps to energy via anaerobic digestion. EBMUD’s wastewater treatment plant has an excess capacity because canneries that previously resided in the Bay Area relocated resulting in the facility receiving less wastewater than estimated when it was constructed. Waste haulers collect post-consumer food waste from local restaurants and markets and take it to EBMUD where the captured methane is used as a renewable source of energy to power the treatment plant. After the digestion process, the leftover material is be composted and used as a natural fertilizer.

The first food waste anaerobic digestion plant in Britain to be built at a sewage treatment plant is the city of Bristol. The plant, located at a Wessex Water sewage works in Avonmouth, process 40,000 tonnes of food waste a year from homes, supermarkets and business across the southwest and generate enough energy to power around 3,000 homes.

Prospects of Algae Biofuels in Middle East

Algae biofuels have the potential to become a renewable, cost-effective alternative for fossil fuels with reduced impact on the environment. Algae hold tremendous potential to provide a non-food, high-yield, non-arable land use source of renewable fuels like biodiesel, bioethanol, hydrogen etc. Microalgae are considered as a potential oleo-feedstock, as they produce lipids through photosynthesis, i.e. using only CO2, water, sunlight, phosphates, nitrates and other (oligo) elements that can be found in residual waters.

algae-middle-east

Algae also produce proteins, isoprenoids and polysaccharides. Some strains of algae ferment sugars to produce alcohols, under the right growing conditions. Their biomass can be processed to different sorts of chemicals and polymers (Polysaccharides, enzymes, pigments and minerals), biofuels (e.g. biodiesel, alkanes and alcohols), food and animal feed (PUFA, vitamins, etc.) as well as bioactive compounds (antibiotics, antioxidant and metabolites) through down-processing technology such as transesterification, pyrolysis and continuous catalysis using microspheres.

Microalgae are the fastest growing photosynthesizing organism capable of completing an entire growing cycle every few days. Up to 50% of algae’s weight is comprised of oil, compared with, for example, oil palm which yields just about 20% of its weight in oil. Algae can be grown on non-arable land (including deserts), most of them do not require fresh water, and their nutritional value is high. Extensive R&D efforts are underway worldwide, especially in North America and Europe, with a high number of start-up companies developing different options for commercializing algae farming.

Prospects of Algae Biofuels in the Middle East

The demand for fossil fuels is growing continuously all around the world and the Middle East is not an exception. The domestic consumption of energy in the Middle East is increasing at an astonishing rate, e.g. Saudi Arabia’s consumption of oil and gas rose by about 5.9 percent over the past five years while electricity demand is witnessing annual growth rate of 8 percent. Although Middle Eastern countries are world’s leading producers of fossil fuels, several cleantech initiatives have been launched in last few years which shows the commitment of regional countries in exploiting renewable sources of energy.

Algae biofuels is an attractive proposition for Middle East countries to offset the environmental impact of the oil and gas industry. The region is highly suitable for mass production of algae because of the following reasons:

  • Presence of large tracts of non-arable lands and extensive coastline.
  • Presence of numerous oil refineries and power plants (as points of CO2 capture) and desalination plants (for salt reuse).
  • Extremely favorable climatic conditions (highest annual solar irradiance).
  • Presence of a large number of sewage and wastewater treatment plants.
  • Existence of highly lipid productive microalgae species in coastal waters.

These factors makes it imperative on Middle East nations to develop a robust Research, Development and Market Deployment plan for a comprehensive microalgal biomass-based biorefinery approach for bio-product synthesis. An integrated and gradual appreciation of technical, economic, social and environmental issues should be considered for a successful implementation of the microalgae-based oleo-feedstock (MBOFs) industry in the region.

How the Biofuel Industry is Growing in the US

drop-in-biofuelsBiofuels were once forgotten in the United States, mainly when huge petroleum deposits kept fuel prices low.  With the increase in oil prices recently, the biofuel industry in the US is rising significantly.  Experts predict that this green energy efficient industry will continue to grow within the next 7 to 10 years.

The Source of Biofuels

Those who are concerned with the prospect of global warming love the potential use of biofuels. Produced either directly or indirectly from animal waste and plant materials, biofuels are less costly than other types of fuel.  Already in the national and global market, the trend for this fuel is rising.

Online Reverse Auction Software

Due to the growth of the biofuel industry, online software for energy brokers and energy suppliers is an available market for entrepreneurs.  The software to efficiently sell energy services to purchasers is a must have for suppliers and brokers.  The reverse auction process effectively conducts online business for those in the biofuel industry.

Both regulated and deregulated gas and electricity markets are involved in the reverse auction process in which the buyer and seller roles are reversed.  The buyer is given the option of testing and evaluating multiple pricing parameters to find a good fit.  Commercial, industrial, and manufacturing facilities take advantage of this platform.

Reverse Auction Benefits

Reverse auctions in the biofuel industry have been said to cut costs tremendously.  Although the seller pays a fee to the service provider, the bidding process cuts costs all around for both buyer and seller.  A situation in which both sides win is seen as a huge benefit by all involved.

As a very lucrative market, the biofuel industry benefits from reverse auctions.  Market efficiency is increased, and the process of obtaining the goods and services is enhanced.  Proper software and other technical aspects of the process is essential thus the reason that the online reverse auction software market is critical.  Quality and professional relationships are enhanced rather than compromised as is often the case in other markets.

Biofuel Market Projections and Uses

According to market research, the biofuel industry is expected to reach approximately 218 billion dollars by 2022.  A 4.5% growth is expected by 2022 as well.  Investors see these projections as an open door of opportunity.  By the year 2025, the increase is predicted to be at approximately 240 billion dollars.

Biofuel is used for other purposes besides first-generation fuel.  It is used in vegetable oil and cosmetics, and it is used to treat Vitamin A deficiency and other health issues. Biofuel is predicted to aid the improvement of economic conditions due to its health benefits and appeal to green energy supporters.  These factors explain the reasons for the projected growth and profit for this industry.

With the continued growth of the biofuel industry, reverse auctions will be a much-needed process.  The efficient software to accompany reverse auctions will keep the market flowing which will further aid the growth of the industry for years to come.

Overview of Bioenergy Technologies

A wide range of technologies are available for realizing the energy potential of biomass wastes, ranging from very simple systems for disposing of dry waste to more complex technologies capable of dealing with large amounts of industrial waste. Conversion routes for biomass wastes are generally thermo-chemical or bio-chemical, but may also include chemical and physical.

Thermal Technologies

The three principal methods of thermo-chemical conversion corresponding to each of these energy carriers are combustion in excess air, gasification in reduced air, and pyrolysis in the absence of air. Direct combustion is the best established and most commonly used technology for converting wastes to heat. During combustion, biomass is burnt in excess air to produce heat. The first stage of combustion involves the evolution of combustible vapours from wastes, which burn as flames. Steam is expanded through a conventional turbo-alternator to produce electricity. The residual material, in the form of charcoal, is burnt in a forced air supply to give more heat.

Co-firing or co-combustion of biomass wastes with coal and other fossil fuels can provide a short-term, low-risk, low-cost option for producing renewable energy while simultaneously reducing the use of fossil fuels. Co-firing involves utilizing existing power generating plants that are fired with fossil fuel (generally coal), and displacing a small proportion of the fossil fuel with renewable biomass fuels. Co-firing has the major advantage of avoiding the construction of new, dedicated, waste-to-energy power plant. An existing power station is modified to accept the waste resource and utilize it to produce a minor proportion of its electricity.

Gasification systems operate by heating biomass wastes in an environment where the solid waste breaks down to form a flammable gas. The gasification of biomass takes place in a restricted supply of air or oxygen at temperatures up to 1200–1300°C. The gas produced—synthesis gas, or syngas—can be cleaned, filtered, and then burned in a gas turbine in simple or combined-cycle mode, comparable to LFG or biogas produced from an anaerobic digester. The final fuel gas consists principally of carbon monoxide, hydrogen and methane with small amounts of higher hydrocarbons. This fuel gas may be burnt to generate heat; alternatively it may be processed and then used as fuel for gas-fired engines or gas turbines to drive generators. In smaller systems, the syngas can be fired in reciprocating engines, micro-turbines, Stirling engines, or fuel cells.

Pyrolysis is thermal decomposition occurring in the absence of oxygen. During the pyrolysis process, biomass waste is heated either in the absence of air (i.e. indirectly), or by the partial combustion of some of the waste in a restricted air or oxygen supply. This results in the thermal decomposition of the waste to form a combination of a solid char, gas, and liquid bio-oil, which can be used as a liquid fuel or upgraded and further processed to value-added products.

Biochemical Technologies

Biochemical processes, like anaerobic digestion, can also produce clean energy in the form of biogas which can be converted to power and heat using a gas engine. Anaerobic digestion is a series of chemical reactions during which organic material is decomposed through the metabolic pathways of naturally occurring microorganisms in an oxygen depleted environment. In addition, wastes can also yield liquid fuels, such as cellulosic ethanol and biodiesel, which can be used to replace petroleum-based fuels.

Anaerobic digestion is the natural biological process which stabilizes organic waste in the absence of air and transforms it into biogas and biofertilizer. Almost any organic material can be processed with anaerobic digestion. This includes biodegradable waste materials such as municipal solid waste, animal manure, poultry litter, food wastes, sewage and industrial wastes. An anaerobic digestion plant produces two outputs, biogas and digestate, both can be further processed or utilized to produce secondary outputs. Biogas can be used for producing electricity and heat, as a natural gas substitute and also a transportation fuel. Digestate can be further processed to produce liquor and a fibrous material. The fiber, which can be processed into compost, is a bulky material with low levels of nutrients and can be used as a soil conditioner or a low level fertilizer.

A variety of fuels can be produced from biomass wastes including liquid fuels, such as ethanol, methanol, biodiesel, Fischer-Tropsch diesel, and gaseous fuels, such as hydrogen and methane. The resource base for biofuel production is composed of a wide variety of forestry and agricultural resources, industrial processing residues, and municipal solid and urban wood residues. The largest potential feedstock for ethanol is lignocellulosic biomass wastes, which includes materials such as agricultural residues (corn stover, crop straws and bagasse), herbaceous crops (alfalfa, switchgrass), short rotation woody crops, forestry residues, waste paper and other wastes (municipal and industrial). The three major steps involved in cellulosic ethanol production are pretreatment, enzymatic hydrolysis, and fermentation. Biomass is pretreated to improve the accessibility of enzymes. After pretreatment, biomass undergoes enzymatic hydrolysis for conversion of polysaccharides into monomer sugars, such as glucose and xylose. Subsequently, sugars are fermented to ethanol by the use of different microorganisms. Bioethanol production from these feedstocks could be an attractive alternative for disposal of these residues. Importantly, lignocellulosic feedstocks do not interfere with food security.
