Gravity batteries work in a similar way to pumped hydro. They involve funnelling water uphill before releasing it through turbines to generate energy. This process can be reversed to store energy, making gravity batteries a promising solution for large-scale, location-independent energy storage.
Gravity batteries are not based on chemistry, but on the force of gravity. Underpinned by Newton's law – what goes up, must come down – this new field of energy storage technology is, in principle, remarkably simple.
China, abundant in mountain resources, presents good development prospects for MGES, particularly in small islands and coastal areas. In mountainous regions with suitable track laying and a certain slope, rail-type gravity energy storage exhibits significant development potential and can essentially replace pumped storage.
