UK firm Gravitricity says its experimental energy storage project in Edinburgh is a success, paving the way for full-scale mine shaft energy sites. A novel energy storage technology, which involves suspending heavy weights above deep mine shafts, is a “serious contender” in the global energy storage market, its creators have said. Gravitricity told i its demonstrator project built in Edinburgh earlier this year has proved a success, with the team raising and lowering two 25-tonne weights to generate power. “These tests confirm our modelling and show that gravity energy storage is a serious contender in the global energy storage market,” said company managing director Charlie Blair. Gravitricity’s Edinburgh demonstrator raised and lowered weights above ground. The start-up now plans to start fundraising for a full-scale project that will see 500-tonne weights dropped down into mine shafts 750 metres deep. Each weight would produce about 1MWh of energy storage capacity, enough to provide power to hundreds of homes for an hour, and would cost £8 to £16m to build.
