Grav-Batt Energy LLC
Henrico, Virginia
We turn abandoned Virginia coal-mine shafts into America’s toughest, longest-lasting energy storage systems — using nothing but gravity.
Our weights are built from local construction demolition waste and stabilized coal ash — turning yesterday’s liabilities into tomorrow’s carbon-free power at negative material cost.
First pilot targeted for 2027, with a goal of 12–50+ hours of firm, dispatchable electricity, 80–90% round-trip efficiency. No rare earths. No degradation. No batteries.
Founded and led by retired U.S. Air Force veteran and physicist Gabriel Baker, putting military precision and American ingenuity to work for clean energy and Virginia coalfield communities.
Currently pursuing SDVOSB certification, AMLER/DOE funding, and now a proud member of the LDES Consortium.

Grav-Batt Energy LLC

Business name: Grav-Batt Energy LLC

Tagline: Gravity-Based Long-Duration Energy Storage in Repurposed Virginia Coal Mines

Description (use this for the About section):
Grav-Batt Energy LLC is a service-disabled veteran-owned small business (SDVOSB) founded by retired U.S. Air Force veteran and physics student Gabriel Baker. We are developing a 1 MW gravity energy storage pilot in the historic Merrimac Mine near Virginia Tech (Montgomery County, VA). By lowering and raising recycled concrete weights in a 500–800 ft abandoned coal-mine shaft, we deliver 12–50+ hour carbon-free power at <$0.03/kWh LCOS using commercial-off-the-shelf equipment. The pilot qualifies for AMLER and DOE LDES funding and is collaborating with Virginia Tech and the Sandia LDES Consortium.
