What is advanced rail energy storage?

Advanced Rail Energy Storage (ARES) uses proven rail technology to harness the power of gravity, providing a utility-scale storage solution at a cost that beats batteries. ARES’ highly efficient electric motors drive mass cars uphill, converting electric power to mechanical potential energy.

How does Ares energy storage work?

ARES energy storage technology employs a fleet of electric traction drive shuttle-trains, operating on a closed low-friction automated steel rail network to transport a field of heavy masses between two storage yards at different elevations.

How long do ARES Systems last?

ARES systems are machines and have a 40-year service life with no degradation and no thermal runaway. ARES uses recycled steel rails, low-carbon and reclaimable mass cars, sophisticated motors and electronics, and freely available gravity, providing a fully sustainable renewable energy storage solution for utility-scale deployment.

How do Ares shuttle trains work?

During periods where excess energy is available on the grid, ARES shuttle-trains draw electricity from the grid, which powers their individual axle-drive motors, as they transport a continuous flow of masses uphill against the force of gravity to an upper storage yard.

Where is Ares Nevada launching a new energy storage project?

A project nearly a full decade in the making, ARES Nevada LLC has finally moved the first shovelful of dirt to kick off construction of its brand new energy storage project, the ARES GravityLine, located right here in the Pahrump Valley, with an official groundbreaking ceremony hosted on Thursday, Oct. 8 in honor of the Read more >

Is Ares a good choice for long-duration energy storage?

ARES plans to actively participate in the frequency regulation market in CAISO , confident in their fast response time. Since there is no evaporation, as with PSH, the self-discharge rate or the energy loss during the storage is extremely low, making them an ideal candidate for long-duration energy storage.
