The gas that heats your home might come from the grass beneath your feet, at least if British renewable energy company is successful.
Ecotricity, one of the world's first renewable energy companies, is building a 'green gas mill' at Sparsholt College near Winchester that will , which can be used instead of natural gas to power and heat homes in the UK. When the mill comes online in 2018, it is expected to power around 4,000 homes.
Ecotricity plans to collect the grass from the many unused fields and meadows in the country. The company estimates that a single acre of grass is enough to fully heat a home. By maintaining those fields, the company also creates thousands of acres of wildlife habitat.
In addition, growing and harvesting grass is carbon neutral, or at least close to it, which is beneficial to the environment. And methane can be pumped through existing gas piping right alongside natural gas.
As Ecotricity seeks to build more mills in addition to the first one, it hopes that grass-based methane could completely replace natural gas produced by fracking, which has severe environmental and health concerns.
