A novel 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  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...…A novel 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  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...WW…

From the rocky outcrops of Iceland to the to the sunny plains of Texas, engineers are building giant machines to suck carbon dioxide out of the atmosphere. It sounds like science fiction, but the companies behind this technology insist it could be a The world has dithered for too long over the task of cutting greenhouse gas emissions, and scientists agree global climate targets are slipping out of reach. To keep warming below 1.5°C – the “safe” climate threshold  –  and maintain the perks of modern life, the world will have to work out a way to remove between 100...…From the rocky outcrops of Iceland to the to the sunny plains of Texas, engineers are building giant machines to suck carbon dioxide out of the atmosphere. It sounds like science fiction, but the companies behind this technology insist it could be a The world has dithered for too long over the task of cutting greenhouse gas emissions, and scientists agree global climate targets are slipping out of reach.
