The ability to store intermittent renewable energy from wind and solar and capturing methane emissions from common waste streams to displace natural gas usage are two technologies poised to play a bigger role in a lower carbon future.
While they play separate roles and are at different stages of adoption, energy storage and biogas — also known as renewable natural gas — are poised for growth under increasingly aggressive state and federal climate policies. They also both face similar barriers to more widespread deployment, notably cost and supportive policies.
