Biogas upgrading / Renewable-Natural-Gas (RNG)

Biomethane (also known as RNG - renewable natural gas) is purified form of biogas that meets the quality standards for natural gas. It usually contains above 96% of methane and can be used as a natural gas substitute. Biomethane can be injected into the existing natural gas grid and used as a natural gas substitute for all end-user applications such as cooking, heating and cooling, power generation, transport, etc.
