A college in Hampshire has teamed up with green energy supplier Ecotricity to build an anaerobic digestion (AD) mill on campus, it was announced yesterday. Sparsholt College has announced its intention to build a Green Gas Mill after receiving support from clean energy company Ecotricity and a grant from the Enterprise M3 Local Enterprise Partnership. Ecotricity said the 6MW plant will convert locally harvested grass into carbon neutral green gas, providing enough energy to supply renewable heat to almost 5,000 homes each year. The gas created will be used to supply both the college and local residents. The AD plant would be the latest in a series of green developments from the college, which has already installed a rooftop solar array and last year submitted plans to build a 500KW wind turbine at its site. Tim Jackson, college principal, said the development would put the college at “the centre of what is the future of gas generation in Britain”.
