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.

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 >

How does rail-based gravity storage work?

Similar to hydro, ARES uses the potential mechanical energy available due to gravity. The figures below demonstrate how rail-based gravity storage works, at a basic level. Figure 1: Electricity is pulled from the grid to turn a highly efficient electric motor lifting a heavy mass car uphill.

Should you invest in rail storage?

Rail storage has a lot to recommend it. For one thing, though ARES is the first company to apply it to the task of energy storage, rail itself is an extremely well-understood technology. Almost everything ARES uses is off-the-shelf — no experimental tech or breakthroughs required. That substantially reduces investment risk.
