Already practiced in Europe on a relatively large scale, feeding biogas into the natural gas grid is now a fact in the US too. Environmental Power Corporation today announced that its subsidiary, Microgy Holdings, LLC, has achieved the initial delivery of pipeline quality renewable natural gas .
The facility is able to generate biogas from manure and other agricultural waste streams, condition the biogas to natural gas standards and distribute it via a commercial pipeline. Microgy's has branded, the renewable, pipeline-quality biomethane product as 'Renewable Natural Gas'.
At full build out, Huckabay Ridge may be the largest biogas production facility in the world, with annual output of approximately 650,000 MMbtus of RNG per year - the equivalent of over 4.6 million gallons (17.4 million liters) of heating oil.
"Our standardized modular plants will enable us to implement numerous large-scale RNG facilities rapidly and in a cost-effective manner."
