Grid-scale energy storage
For a Carbon-Free Future

get updatesLearn more
TerraStor enables electrical grids to achieve 100% renewable penetration by developing grid-scale, long-duration energy storage systems. We deploy advanced compressed air energy storage (ACAES) technology to create giant mechanical batteries, utilizing free and abundant air and natural geology for a clean, simple, and economic storage solution.

Our guiding principles

independent energy storage provide (IESP)

We are reinventing the electrical grid by solving difficult technological problems to create low-cost, highly-responsive, extra-long duration, grid-scale energy storage for a 24/7, 365-days a year carbon-free future.
Coins for low cost

Scale
Matters

Only solutions that work at scale can make a meaningful contribution to the full energy transition.

work with
nature

Only those solutions that work with nature, and not against it or in spite of it, will be cost-effective and therefore successful.

leverage existing tech

The existing energy and power industries have a lot of technology and know-how to offer the energy transition.

Grid-scale energy storage

While no project is too small for us, we target those that can deliver power of at least 100 megawatts and energy storage of at least one gigawatt-hour because we must make big moves quickly to enable a 100% carbon-free electrical grid.

Carbon-free Energy future

We aspire towards a socially responsible and carbon-free energy future. Excess renewable energy must be stored for use during times when the sun isn’t shining or the wind isn’t blowing. We are working towards a day when every minute of every day, our electrical grid has zero carbon footprint.
