6 FAQs about [Railroad cars energy storage]

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.

Should rail vehicles have onboard energy storage systems?

How does rail compare to other forms of energy storage?

Rail also compares favorably to other forms of energy storage. ARES systems do not respond quite as fast as batteries (five to 10 seconds, as opposed to effectively instant), but the company claims its capital costs are far lower. Also, rail cars and concrete slabs, unlike batteries, do not degrade over time.

Can rail-based mobile energy storage help the grid?

We have estimated the ability of rail-based mobile energy storage (RMES) — mobile containerized batteries, transported by rail between US power-sector regions 3 — to aid the grid in withstanding and recovering from high-impact, low-frequency events.

Could a land-based alternative provide grid-scale energy storage using electric locomotives?

Santa Barbara, California-based company Advanced Rail Energy Storage (ARES) has come up with a land-based alternative that would provide grid scale energy storage using electric locomotives. ARES’ technology uses heavy rail cars that are pushed to the top of a grade using excess power from renewable energy plants or when electricity demand is low.

What types of energy can be stored in a rail-based gravity storage system?

Energy can be stored in many forms such as chemical energy (batteries), thermal energy (heat), kinetic energy (flywheels) and potential mechanical energy (hydro). 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.
