Energy Storage

Energy drives all processes.

Producing and using energy efficiently
and cleanly is essential to our future.

Our technology will reduce waste within the existing energy infrastructure, and unlock the potential of renewables for a sustainable future.

Less than 1% of the daily energy used in the US can be stored on the grid.

95% of this storage is pumped hydroelectricity, a legacy technology where excess energy is used to pump water uphill to a reservoir, for later release through a hydroelectric generator.

This is very geographically limiting.

We aim to bring widespread
electrochemical storage to the grid
for use anywhere, anytime.
