Renewable gas

National Grid, which distributes gas and electricity in northeastern US and the UK, says that renewable gas could meet 16% of demand.

Published in a white paper, Renewable Gas - Vision for a Sustainable Gas Network, the company research shows how biomethane produced from waste could meet the needs of its US customers in Massachusetts, New York, Rhode Island and New Hampshire. With investment of around $7 billion across the four states it covers, National Grid says renewable gas could meet up to 25% of demand and reduce greenhouse gas emissions by around 16 million tons a year.

Unconventional sources such as dairy farms, waste water treatment plants, landfills, wood waste and food waste plants will get linked into the grid. In fact, any unit that generates biodegradable waste can be a potential source. An excellent way to get rid fo colossal waste we generate too.

In the UK, National Grid has joined forces with British Gas and a local brewer, Adnams, to use waste from the brewing process to produce biomethane and inject it directly into the UK’s gas network. The remaining waste is an effective manure material.
