An Introduction to Biomethane

Biogas that has been upgraded by removing hydrogen sulphide, carbon dioxide and moisture is known as biomethane. Biomethane is less corrosive than biogas, apart from being more valuable as a vehicle fuel. The typical composition of raw biogas does not meet the minimum CNG fuel specifications. In particular, the COand sulfur content in raw biogas is too high for it to be used as vehicle fuel without additional processing.

Liquified Biomethane

Biomethane can be liquefied, creating a product known as liquefied biomethane (LBM). Biomethane is stored for future use, usually either as liquefied biomethane or compressed biomethane (CBM) or  since its production typically exceeds immediate on-site demand.

Two of the main advantages of LBM are that it can be transported relatively easily and it can be dispensed to either LNG vehicles or CNG vehicles. Liquid biomethane is transported in the same manner as LNG, that is, via insulated tanker trucks designed for transportation of cryogenic liquids.

Compressed Biomethane

Biomethane can be stored as CBM to save space. The gas is stored in steel cylinders such as those typically used for storage of other commercial gases. Storage facilities must be adequately fitted with safety devices such as rupture disks and pressure relief valves.

The cost of compressing gas to high pressures between 2,000 and 5,000 psi is much greater than the cost of compressing gas for medium-pressure storage. Because of these high costs, the biogas is typically upgraded to biomethane prior to compression.

Applications of Biomethane

The utilization of biomethane as a source of energy is a crucial step toward a sustainable energy supply. Biomethane is more flexible in its application than other renewable sources of energy. Its ability to be injected directly into the existing natural gas grid allows for energy-efficient and cost-effective transport. This allows gas grid operators to enable consumers to make an easy transition to a renewable source of gas. The diverse, flexible spectrum of applications in the areas of electricity generation, heat provision, and mobility creates a broad base of potential customers.

Biomethane can be used to generate electricity and heating from within smaller decentralized, or large centrally-located combined heat and power plants. It can be used by heating systems with a highly efficient fuel value, and employed as a regenerative power source in gas-powered vehicles.

Biomethane to Grid

Biogas can be upgraded to biomethane and injected into the natural gas grid to substitute natural gas or can be compressed and fuelled via a pumping station at the place of production. Biomethane can be injected and distributed through the natural gas grid, after it has been compressed to the pipeline pressure. In many EU countries, the access to the gas grid is guaranteed for all biogas suppliers.

One important advantage of using gas grid for biomethane distribution is that the grid connects the production site of biomethane, which is usually in rural areas, with more densely populated areas. This enables the gas to reach new customers. Injected biomethane can be used at any ratio with natural gas as vehicle fuel.

Biomethane is more flexible in its application than other renewable sources of energy.

The main barriers for biomethane injection are the high costs of upgrading and grid connection. Grid injection is also limited by location of suitable biomethane production and upgrading sites, which have to be close to the natural gas grid.

Several European nations have introduced standards (certification systems) for injecting biogas into the natural gas grid. The standards, prescribing the limits for components like sulphur, oxygen, particles and water dew point, have the aim of avoiding contamination of the gas grid or the end users. In Europe, biogas feed plants are in operation in Sweden, Germany, Austria, the Netherlands, Switzerland and France.

Which Option to Consider While Purchasing Forklift: Buy, Lease or Rent?

There are various options to consider when you want to acquire a forklift. As this is no cheap piece of equipment. Making a decision requires you to use a unique lens to decide on what’s best for your scale of operation. Are you torn between renting, leasing or buying? To help you through this challenging process, below, you will find points that will assist you in determining the best cause of action for your business:

 

  1. Renting a forklift

If you in a seasonal peak during your business period or in need of moving extra freight, renting is the choice you can take. When you choose to rent a forklift, you are sure to benefit from experimenting with different classes of forklifts to see which one increases productivity.

 However, rentals are somewhat expensive compared to leasing or buying. This is because you will have to cover maintenance costs as well as the time that the forklift will be idle while at the dealership between rental assignments.

During renting, remember that there will be building waste that needs attention. You need to take care of transportation waste, construction waste sorting as well as recycling streams.

  1. Leasing a forklift

While you are contemplating leasing, you can set your number of years on which you intend to rent the machine. Having a short lease will allow you to work better if you want to become fluid. Leasing will provide you with less monthly payments when compared to renting or buying.

This option allows you to test-drive new models without making a permanent commitment to buying it. You will be at a position to make adjustments where you see fit in terms of decreasing the fleet size, changing product mix or modifying terms of the lease

  1. Buying a forklift

Does your business have a preference for owning all the capital equipment it has? Do you want to access a higher competitive credit line? Is your business stable, or you anticipate to use the material for more than 20 years? Do you have cash at hand to make a purchase immediately? If yes, the best course of action that you should proceed with it buying your forklift machine.

This way, you are sure to make a better return on investment because when you rent over a long period, rental fee tends to become higher as compared to monthly financial costs.

Buying a forklift will allow you to make your modifications than with a rental or leased equipment. You get customized options which suit your specific needs.

You can enjoy a tax deduction as purchased forklift are entitled to a reduced tax.

Conclusion

When deciding on what purchasing technique to use, be sure to analyze your business needs before making any rash decisions. Do not forget to offer your workers a Solutions on Waste, Recycling and Processing Recyclable Materials during your contraction tenure. This will go hand in hand with the ultimate choice you make in purchasing option that will work for your company.
