Burning fat for the environment

A Kent supermarket is believed to be the first in the UK to use a fat-burning electricity generating system.

Sainsbury's in Hythe is using a new Smart Grid system which activates the site's bio fuel generator when there is a higher demand for power.

The generator is fuelled by waste fat from the store, and electrical systems can be altered to reduce consumption.

"We now aim to roll this out to at least six stores by the end of the year," said Sainsbury's Neil Sachdev.

Smart Grid system

The system monitors the grid and activates the store's bio fuel generator when there is an increased demand for electricity.

Additional technology will deactivate or reducing the site's heating, ventilation and lighting systems at peak time.

Neil Sachdev, explained: "To ensure that both consumers and businesses have enough electricity at all times, power stations are kept on stand-by, ready to come into action when required.

"The trouble is that two-thirds of the UK's stand by power comes from high-carbon-emitting non-renewable sources.

"By introducing this technology, we will cut the UK's dependence on fossil fuels, reduce our own energy costs and reduce our CO2 emissions."

The creation of Hythe's Smart Grid store is result of Sainsbury's partnership with Imperial College London's Faculty of Engineering and Grantham institute for Climate Change.
