As the global hunger for electricity grows and the transition to solar and wind accelerates, electricity storage capacity is urgently needed to handle the challenges of scale and intermittency. Concrete solutions are needed to solve the large-scale electricity storage problem for both daily and seasonal applications, and it’s going to require some heavy lifting. A new generation of gravity batteries have emerged based on the lifting and lowering massive concrete weights. The solution may prove a viable option for storing and releasing grid scale electrical energy over periods as short as seconds to as long as months, which would represent a significant step towards renewable energy utilization.
