Thames Water, 2OC will deliver power from London's fatbergs
(Phys.org) —From fish and chips to pork pies, some of London's tastiest foods create unappetizing and costly fat and oil buildups in drains. These fatbergs, as they are dubbed, end up in the city sewers system. A fatberg is a hefty clump of congealed fat and cooking oil, but also intertwined with other materials passing through the sewers. Leaders at two companies have a plan that, while not making lemonade out of lemons, will do even better, making energy out of leftover fat. Fat and oil from restaurants and build-ups in drains will find re-use as a result of an ambitious plan, it was announced on Sunday. The grease will be fed into what is claimed to be the world's largest fat-fueled power station, at Beckton in east London, to be run by energy company, 2OC.
