Gravity – the solution to energy storage?
Heindl’s Gravity Storage, which uses the gravitational power of a huge mass of rock to store large amounts of electricity. Lithium-ion batteries seem to be used everywhere – from tablets and smart phones, to electric vehicles, to large-scale stationary storage systems like Tesla’s mega-battery in South Australia. Key to this success is their modularity – the ability to stack any number of battery cells together to create storage systems of any size. As a result, over the past
