The answer to UK energy security could literally be under our noses. Green energy company Ecotricity says it has found a way to produce gas from grass,l offering a viable alternative to fracking. After several years of research and development Ecotricity has this week announced that it has come up with a concept that uses anaerobic digestion to turn grass sourced from marginal land on farms into biogas, which is then purified into biomethane and fed straight into the national grid. The process is said to also result in the production of a fertiliser that will go back onto the farmers’ fields and help to improve soil quality.
