The chairman of renewable energy company Ecotricity is investing £ 10 billion in the first generation of a biomethane producing technology . Described as " green gas mills " , the plants take grass harvested from nearby fields and break it down in an anaerobic digester . The grass is then transformed into electricity within 45 minutes and is then injected it into the national network . A report by Ecotricity says there is around 300 million hectares of suitable grassland in the UK , enough to match the amount of gas the bio ##mass forecasts the country will consume by 2035 . However , this would require building as many as 5000 biomethane mills .

Described as "green gas mills", the plants take grass harvested from nearby fields and break it down in an anaerobic digester. The grass is then transformed into biomethane within 45 days and is then injected it into the national network. A report by Ecotricity says there is around 6 million hectares of suitable grassland in the UK, enough to match the amount of gas the National Grid forecasts the country will consume by 2035. However, this would require building as many as 5000 biomethane mills.
