Terrament is building long-duration energy storage for grid utilities and AI data centers using gravity batteries deployed underground.
By maximizing height and weight, our patented solution achieves 20x more energy density than any other gravity solution.
Terrament's gravity storage solution is low-risk:
We don't depend on critical minerals, and we don't use any chemical batteries. Our innovative system uses only well-established technologies: We leverage the same motor/generators used in wind turbines, and we use the same mile-deep mine shafts which have been built by mining companies for over 50 years.
The threat of climate change has sparked action to replace fossil fuels with wind and solar energy. But wind and solar are intermittent resources; the wind doesn't always blow, and the sun doesn't always shine. At the same time, artificial intelligence is driving explosive growth in data centers, with AI servers using up to 10 times the power of standard servers.
Today, 90% of the world's energy storage is pumped hydro, which is a nearly tapped out resource. And Lithium-ion batteries are too expensive at long durations.
Terrament replicates pumped hydro, but without needing water or hills.
Terrament is based out of Newlab in Brooklyn, NY. We have been awarded two U.S. Patents, with further patents pending. We are grateful to receive pro bono legal support from Foley Hoag LLP
