With a $1.1 million pilot project, Terasen will develop B.C.’s first biogas alternative energy project with the delivery of biomethane through its natural gas distribution system. The project isn’t the first of its kind – the US is beating it to the punch – but the idea is still in infancy.
“This pilot project will provide enough energy for 100 homes and reduce greenhouse gas emissions by 500 tonnes each year,” says Doug Stout, Terasen’s VP of marketing and business development.
The gas from the sewage treatment plant is almost pure methane and is produced from the sewage’s digestion or decomposition when solids are separated into liquid waste. That excess gas is usually burned off, but waste not want not, so it’ll be used to power homes. Just think, your poop powering the bathroom light by which you read your newspaper while, well, pooping. Brings a whole new meaning to Terasen's tagline, doesn't it?
Conveniently, a gas pipeline nearby the sewage treatment plant makes it easy to transport the excess gas after impurities have been removed and the gas is pressurized for delivery in the pipe.
The Lions Gate project is slated to begin by July 2009 and Terasen hopes to use what it learns from this pilot program to develop larger-scale applications from harvesting methane from agriculture waste. It looks promising. But I don’t care how much it may help the environment, I’m not going to be strapping on one of those backpacks that those cows in
