Biomethane (also referred to as green gas) is a direct substitute for fossil natural gas that can be used by businesses to help tackle scope 1 emissions. 

Biogas is a mixture of methane, CO₂ and small quantities of other gases produced by the anaerobic digestion of organic matter in an oxygen-free environment. 

For our new generation of AD plants, the feedstocks we work with are purposely-grown energy crops (such as maize or rye) from the areas local to our plants and grown as part of a sustainable, long crop rotation. 

Biomethane is a near-pure source of methane produced by “upgrading” biogas (a process that removes any CO₂ and other contaminants present in the biogas). 

Once upgraded with propane to become biomethane, this gas is indistinguishable from natural gas and can be injected into the grid without the need for any changes in transmission, distribution infrastructure or end-user equipment.

This means without any additional investment required in additional infrastructure, businesses can decarbonise their gas and heat requirements through their acquisition of green gas. This is ideal for difficult to decarbonise sectors such as shipping, heat and heavy transport and many others. 

The production of biomethane in our new generation of plants utilising BECCS technology is carbon negative. 

Because our inputs are primarily locally grown energy crops, the associated costs are independent of gas and oil price volatility. For similar reasons UK sourced energy helps improve the UK’s energy security.
