Scientists charged with developing giant 'green energy' battery

Eon UK is developing a giant battery designed to store electricity generated by wind farms and solar panels.

Scientists at the energy group's technology centre in Nottingham aim to build a large-scale prototype that would be able to store one megawatt of electricity for four hours - the equivalent to 10m AA batteries and the same size as four articulated lorry containers.


"Green power is only generated from wind farms when the wind blows and that might not be when the power's needed by customers," said Bob Taylor, managing director of energy wholesale and technology. "By researching and developing this battery we can store the power generated by wind farms any time and then use it when our customers need it the most.
