The Rise of Bioenergy in China: Trends, Challenges and Future Prospects

China has recently emerged as one of the economic powerhouses of the world. Not only does this status continue to redefine what was considered to represent a somewhat “backwards” society, but plenty of employment opportunities await. This has also given rise to several interesting trends. From the growing number of Chinese classes online which cater to foreign migrants to increased international investment, the future does indeed look bright.

It is also important to mention how China has begun to capitalise upon innovative solutions in the hopes of reducing the impacts of climate change. One interesting example can be seen in the use of bioenergy as a viable substitute for traditional fossil fuels. What are some current trends to note and are there any challenges that will need to be addressed in the coming years?

Promising Statistics

Many readers will be surprised to learn that up to 80 per cent of raw biomass materials are now being used to generate power throughout China. Considering the population of this nation, it only stands to reason that such sources of energy abound. Furthermore, the implementation of biomass will help to reduce China’s reliance upon outside nations. This provides a much-needed economic boost and promises an impressive long-term return on investment (ROI).

Such a pronounced trend is at least partially due to a younger Chinese generation that has now become well aware of their role in stemming the effects of climate change. Another undeniable benefit is the simple fact that bioenergy now represents a niche employment sector; providing plenty of opportunities for those with the appropriate skill sets.

What Challenges Await?

While all of the observations outlined above are rather promising, we also need to remember that there are some downsides attributed to biomass in relation to energy production. One potential issue involves industry competition as well as to decide how the resources themselves should be allocated. Wealth distribution could also come into play considering the role that corruption may play in terms of profit margins.

As this summary highlights, another possible sticking point could instead involve operational challenges including:

  • Feedstock management
  • Storage issues
  • Supply and demand
  • High transportation costs
  • A relatively new industry

Other problems such as retooling existing factories in order to support biomass energy production can be rather complicated and expensive.

So, what might the future of bioenergy in China have in store? Most experts agree that relying upon fossil fuels alone as a source of electricity is no longer a viable option. So, it stands to reason that the Chinese government is looking carefully at how biomass can be used as an alternative. Officials also appreciate that many other nations have already curtailed their use of fuels such as coal and natural gas.

The main takeaway point here is that much like any other emerging industry, bioenergy is associated with undeniable advantages as well as some logistical challenges. Still, China should be able to rise to the occasion with planning and foresight.

How Renewable Energy Can Solve Smog Problem in China

China is currently facing serious environmental problems, with potentially few solutions. Currently, this is mostly taking the form of serious smog issues plaguing North China, with more than 24 cities on red alert. However, with airports being shut down due to lacking visibility and the economy of China being heavily disrupted, action needs to be taken to solve this serious smog problem. While limited action has been taken, perhaps renewable energy is the key to cutting down China’s smog.

How Bad Is the Problem?

The smog problem in China has become increasing worse from 2015 to 2017, with more than 90 micrograms of pollution per meter squared. These levels of air pollution are similar to the levels recorded previous to 2014, when the Chinese premier declared a war on pollution due to the health dangers posed by rising air pollution levels.

However, since 2015, levels of air pollution have risen once again. This pollution has had hard hitting effects on urban areas, especially the Chinese capital Beijing, and has caused widespread disruption to the lives of Chinese citizens and economy of the country.

The air pollution leads to the cities becoming hotter than ever. Urban Heat Island effect, which refers to buildings absorbing the sun’s heat well, is exacerbated by the smog. In fact, a car in the heat can reach temperatures of 114 degrees Fahrenheit after just 20 minutes, making travelling on hot days nearly unbearable for any living creature. In order to decrease the heated condition of China, it is essential to decrease the amount of smog covering the cities.

What Has the Chinese Government Done?

The Chinese government has taken limited action in an attempt to minimize the air pollution being created in the country. This includes the Atmospheric Pollution Prevention Plan, which acknowledged the danger posed by air pollution levels and aimed to reduce coal usage in urban areas like Beijing.

However, this is not representative of the main action the government has taken. Primarily, the Chinese government has focused on individual areas and attempting to reduce local pollution levels through efficient coal burning and banning the burning of waste materials, especially on farms. These solutions, while effective on a short-term basis, are not all that is needed, though.

China needs to reduce its overall usage of coal produced energy, which currently stands at 64 percent of total energy consumption. While this has already been happening in China, the further introduction of renewable energy could be of great help to China’s pollution levels.

How Could Renewable Energy Help?

Many people believe renewable energy to be a small affair, something undertaken by the Western world in a vain attempt to reduce our collective guilt concerning climate change and wastage levels. This is simply not the case. Renewable energy is a $120 billion industry that receives investment and application across the world. This includes solar energy, waste-to-energy technology, wind energy, hydroelectric energy and many more attempts to reduce overall energy usage.

Through investment in renewable energy, China could reduce its dependence on coal and increase the efficiency of its energy production and economy. Smog is directly created by China’s use of coal for its energy production, and by investing in other renewable means, China can simultaneously improve its health situation.

In fact, the obviously positive nature of investment in renewable energy can be clearly seen through the Chinese government’s already existing plans to further incorporate it into the economy. In the five-year plan announced in 2016, the Chinese government explicitly stated it would decrease air pollution levels through investment in wind, solar and biomass energy production technologies.

While the plans additionally included investment in making the coal industry more efficient and reducing emissions on an industrial and commercial level, clearly renewable energy is believed to be a valid alternative energy source.

Overall, it is clear that renewable energy can certainly help with China’s serious smog problem. Whether this should be in tangent with further investment in the coal industry or necessitate the end of widespread coal usage in China is still a question for debate.

Biomass Energy and Sustainability

Biomass energy systems offer significant possibilities for reducing greenhouse gas emissions due to their immense potential to replace fossil fuels in energy production. Biomass reduces emissions and enhances carbon sequestration since short-rotation crops or forests established on abandoned agricultural land accumulate carbon in the soil. Biomass energy usually provides an irreversible mitigation effect by reducing carbon dioxide at source, but it may emit more carbon per unit of energy than fossil fuels unless biomass fuels are produced in a sustainable manner.

Biomass resources can play a major role in reducing the reliance on fossil fuels by making use of thermo-chemical conversion technologies. In addition, the increased utilization of biomass-based fuels will be instrumental in safeguarding the environment, generation of new job opportunities, sustainable development and health improvements in rural areas.

The development of efficient biomass handling technology, improvement of agro-forestry systems and establishment of small and large-scale biomass-based power plants can play a major role in sustainable development of rural as well as urban areas. Biomass energy could also aid in modernizing the agricultural economy and creating significant job opportunities.

Harvesting practices remove only a small portion of branches and tops leaving sufficient biomass to conserve organic matter and nutrients. Moreover, the ash obtained after combustion of biomass compensates for nutrient losses by fertilizing the soil periodically in natural forests as well as fields.

The impact of forest biomass utilization on the ecology and biodiversity has been found to be insignificant. Infact, forest residues are environmentally beneficial because of their potential to replace fossil fuels as an energy source.

Plantation of energy crops on abandoned agricultural land will lead to an increase in species diversity. The creation of structurally and species diverse forests helps in reducing the impacts of insects, diseases and weeds. Similarly the artificial creation of diversity is essential when genetically modified or genetically identical species are being planted.

Short-rotation crops give higher yields than forests so smaller tracts are needed to produce biomass which results in the reduction of area under intensive forest management. An intelligent approach in forest management will go a long way in the realization of sustainability goals.

Improvements in agricultural practices promises to increased biomass yields, reductions in cultivation costs, and improved environmental quality. Extensive research in the fields of plant genetics, analytical techniques, remote sensing and geographic information systems (GIS) will immensely help in increasing the energy potential of biomass feedstock.

A large amount of energy is expended in the cultivation and processing of crops like sugarcane, coconut, and rice which can met by utilizing energy-rich residues for electricity production. The integration of biomass-fueled gasifiers in coal-fired power stations would be advantageous in terms of improved flexibility in response to fluctuations in biomass availability and lower investment costs. The growth of the biomass energy industry can also be achieved by laying more stress on green power marketing.
