Creating Green Biomethane

via Anaerobic Digestion

Anaerobic Digestion is the process in which organic waste (feedstock) is collected, processed (chopped and strained) then introduced into an airtight digestor tank, holding approximately 250,000 liters of liquid waste.

​

The digestor is heated to 37 degrees Celsius, with micro-organisms introduced into the mix. As the environment is lacking oxygen, the micro-organisms quickly break down the organic materials over a 30-day period, creating a bio-natural gas.

​

The raw biogas created is comprised mostly of methane, carbon dioxide, water and trace elements. The raw biogas is processed via gas upgrading and desulphurization equipment, creating green biomethane of 99% purity - grid ready.

​

The separated carbon dioxide is processed and package for sale to industrial customers or used to create alternative energy products, while the water vapor is captured and repurposed back into the digestor. Digestates are an additional by-product, an organic fertilizer which is resold either as a liquid or solid, an environmentally friendly alternative to traditional fossil-based fertilizers.

​

The purified biomethane can be delivered directly into an existing natural gas grid network or chilled and distributed as liquide biomethane - LBM.

​

Biomethane is the only functional replacement for natural gas, providing a much greater thermal energy level than either wind or solar and is the desired replacement for heavy industry. By example, every major international shipping company is either converting existing ships or new order vessels, to operate on eMethanol or liquid natural gas as a replacement for diesel / bunker oil. eMethanol can be created using the products of anaerobic digestion.

​

Biomethane can power electolyzers for the creation of green hydrogen. As biomethane has a higher thermal energy level than wind or solar, it creates greater amounts of hydrogen than the energy expended during hydrogen production; a disadvantage with using wind or solar to create green hydrogen.

Unlike wind and solar, anaerobic digestion can operate 24x7x365, and is not dependent upon blowing wind nor sunshine. The energy products created by anaerobic digestion can be stored and are ready for immediately use upon market demand.
