National Grid has today published a white paper - “Renewable Gas - Vision for a Sustainable Gas Network” - that shows how 16% of natural gas demand in the four states National Grid serves (Massachusetts, New York, Rhode Island, New Hampshire) could be met by renewable gas, and focuses on the role of renewable gas in the clean energy future of the United States.

As the US moves towards a low-carbon economy, the paper discusses the potential sources of renewable gas in the northeastern U.S. and provides an overview of renewable gas technology. Derived from existing waste sources, renewable gas can reduce greenhouse gas (GHG) emissions.

The paper also outlines what a future sustainable gas network could look like, as well as what needs to be done make the vision a reality.

In January 2009, National Grid published a similar report, "The potential for renewable gas in the UK".
