Energy storage

Energy storage
Renewable energy production is growing rapidly globally thanks to technological advancement. However, intermittency of solar and wind power output has given rise to big demands for energy storage solutions such as pumped hydro-electric stations, batteries, flywheel and compressed-air energy storage. Energy storage is a key part of the low carbon energy supply system the world aspires to achieve, for cutting greenhouse gas emissions and fighting climate change.
