Home electricity storage solutions are certainly flavour of the month in terms of renewable energy news recently. Take Nissan’s xStorage and Tesla’s Powerwall, for example, both of which are on the verge of being released to the public, and both of which promise to provide valuable savings to homeowners using seriously clever vehicle-to-grid technology (that you really need to be a scientist to fully understand the ins-and-outs of…)

With the second season of Formula E now over, and a whole heap of super powerful race EVs sitting there, the developers of the batteries behind these brutes have been toying with the idea of converting these units into home storage devices. Because why not? It’s estimated one of these puppies could power the average residential home for up to FOUR MONTHS.

“For us, Formula E acts as a proving ground for high power batteries working in harsh environments,” said Paul McNamara, Technical Director at Williams Advanced Engineering. “We have been able to fully test and validate our cooling systems, charge retention and module design, and apply this technology to other projects outside of motorsport.”

And who wouldn’t want Buemi’s championship-winning battery slapped up on their kitchen wall?
