The fastest way to decarbonize our society.
We have combined ultra-low-cost, earth-abundant materials and a breakthrough power conversion technology in a simple and durable energy storage product to enable zero-carbon power every hour of the year, everywhere on earth.
Our Technology
1
2

System is charged

by resistive heating

Intermittent low-cost power

Thermal energy is stored at >1000°C in ultra-low-cost solid media

Antora's thermal battery

Shaped power

Heat on demand

3

Antora’s novel thermophotovoltaic (TPV) heat engine converts radiant heat back into firm electricity on demand

4

Heat can be directly discharged to supply industrial processes and district heat

Features and Advantages

Affordable

Fully installed cost <$10/kWhₑ—20x lower than Li-ion batteries—enables around-the-clock power with lower LCOE than conventional resources

Modular

Solid storage medium and TPV heat engine scale by simple addition of repeated building blocks

Scalable

Earth-abundant raw materials, industrially-mature supply chains, and existing manufacturing lines

Flexible

Fast startup and load-following

Safe operation

No thermal runaway, fire hazard, or reactive materials

Rapid charging

Quickly soak up excess power

Long lifetime

30 year project lifetime, no cycling degradation at 100% depth of discharge

Multi-day storage

Tens to hundreds of hours of firm, dispatchable electricity

Site-able

Energy density on par with Li-ion batteries enables a compact footprint and eliminates geographic and siting constraints

Zero-carbon heat

Optional on-demand discharge of process or district heat at a fraction of the cost of hydrogen and competitive with the cost of natural gas
