Researchers propose a gravity-based system for long-term energy storage.
- A new paper outlines using the the Mountain Gravity Energy Storage (or MGES) for long-term energy storage.
- This approach can be particularly useful in remote, rural and island areas.
- Gravity and hydropower can make this method a successful storage solution.
