World’s Largest Fat-Fuelled Power Station Planned for London

It costs Thames Water about £1 million per month to clear out blockages in sewers, about half of which are caused by fat being discarded down the drain.

But a new initiative will take a bite out of those costs by taking these “fatbergs”, as well as used fat and oil from restaurants, and turning them into energy.

According to Thames Water, fat, oil, and grease (FOG) will be collected and fed into what they’re saying will be “the world’s largest fat-fuelled power station” in East London.

The fat-fuelled plant is being developed by 20C, and is said to be able to produce 130 GWh of renewable energy, which is equivalent to the amount necessary to power 39,000 homes.

75 GWh of this output will be used by Thames Water to run Beckton sewage works and a nearby desalination plant, and the remaining power will be sold to the national energy grid.

“This project is a win-win: renewable power, hedged from the price fluctuations of the non-renewable mainstream power markets, and helping tackle the ongoing operational problem of ‘fatbergs’ in sewers.” – Piers Clark, commercial director for Thames Water

Thames Water is also committed to providing up to half of the fuel needed for the generator, with up to 30 tonnes per day of FOG being diverted from the sewers to the plant. The rest of the fuel will come from waste cooking oil and fat from restaurants, food outlets, and food manufacturers.

The facility is expected to come online sometime in the early part of 2015.
