Gravity Storage is a new technology to store really large amount of electricity: 8 GWh and more a feasible. The System fits perfectly for large scale solar and windpower…
Turning high-rise buildings into batteries
With the rapid reduction in the costs of renewable energy generation, such as wind and solar power, there is a growing need for energy storage technologies to make sure that electricity supply and demand are balanced properly. IIASA researchers have come up with a new energy storage concept that could turn tall buildings into batteries to improve the power quality in urban settings.
Storing renewables with high-rise elevators
Lift Energy Storage Technology is a proposed long-term storage solution that relies on elevators to bring solid masses to the tops of buildings in charging mode. It then lowers the same mass to produce electricity in discharge mode.
Storing renewables via regenerative braking in underground mines
Scientists in Austria have developed a long-term energy storage system that uses regenerative braking to adjust the descent speed of sand in mine shafts and generate electricity.
