Energy from crops
Generating energy from crops is an extremely sustainable process at Severn Trent. In 2014-15 we generated 22 million kWh of electricity, equivalent to the use of around 5000 homes
We have been experimenting with ways to increase the gas yield from our digesters. So far we have tried electrocuting and shredding the material entering the tanks. This year we are going to try adding special bacteria which increase the amount of gas from the same amount of crop. This will reduce our costs if we can stop buying in extra material.
