What we’re less sure about is how we can store renewable energy so that it’s available to us when we need it, not just when the wind is blowing. A number of storage systems are already in development, like large lithium batteries to canisters of compressed air. But none are as elegant as Gravitricity’s “solid weight storage solution” that converts excess electricity into gravitation potential energy. \n\nGravitricity's managing director Charlie Blair joins us to talk more about the company's solution and its plans for the future. \n\nFIND OUT MORE: granttree.co.uk/what-comes-next/45-gravity-powered-batteries/\n\nFIND US ONLINE\nAll previous episodes: granttree.co.uk/what-comes-next/\nTwitter: @wcnpod\nInstagram: @wcnpod\n\nGET IN TOUCH\nQuestions?
