The Guardian reports: A US government agency says it has attained the “holy grail” of energy – the next-generation system of battery storage, that has has been hotly pursued by the likes of Bill Gates and Elon Musk.

Advanced Research Projects Agency-Energy (Arpa-E) – a branch of the Department of Energy – says it achieved its breakthrough technology in seven years.

Ellen Williams, Arpa-E’s director, said: “I think we have reached some holy grails in batteries – just in the sense of demonstrating that we can create a totally new approach to battery technology, make it work, make it commercially viable, and get it out there to let it do its thing,”

If that’s the case, Arpa-E has come out ahead of Gates and Musk in the multi-billion-dollar race to build the next generation battery for power companies and home storage.

Arpa-E was founded in 2009 under Barack Obama’s economic recovery plan to fund early stage research into the generation and storage of energy.

Such projects, or so-called moonshots, were widely seen as too risky for regular investors, but – if they succeed – could potentially be game-changing. [Continue reading…]
