Giant £40 Million Battery for the UK
UK electricity company, Eon, are planning to build a huge battery to store power from sustainable electricity sources. Because sources like wind and solar aren't constantly reliable, some kind of storage is necessary if a 100% sustainable grid is to be created in the future. This is especially true of solar power in the UK, where sunshine is as elusive as an honest politician.Eon's scientists are planning the battery in Nottingham, which will be able to old one megawatt for anything up to four hours. The Guardian helpfully put this into an easily accessible comparison for its readers, "the equivalent to 10 million AA batteries and the same size as four articulated lorry containers." Smaller scale projects have already been underway for some time, but this humongous battery should be completed in autumn 2009.
Bob Taylor of Eon said, "Green power is only generated from wind farms when the wind blows and that might not be when the power's needed by customers. 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. The storage system will also help the development of localised generation. For example, a school with solar panels can store the power generated at weekends and use it when the kids are back in school." ::Guardian
