Proven

Trusted material with centuries of industrial use in high-temperature environments

Superior Performance

Unmatched thermal conductivity, best-in-class heat capacity, and simple radiative heat transfer

Scalable

The fourth-most produced industrial material on Earth, at 1/10th the cost of Lithium-ion

Energy-Dense

Stores four times as much energy as electrochemical batteries with the same volume

HOW IT WORKS

1 Charge
2 Store
3 Deliver

1
RAPID CHARGING WHEN ELECTRICITY IS CHEAP

Electricity is used to resistively heat the carbon blocks. Carbon's high thermal conductivity enables ultra-fast charging that rapidly soaks up the cheapest hours of electricity generation.
2
MULTI-DAY THERMAL STORAGE

The carbon blocks store energy at temperatures up to 2,400°C in a compact and modular system. These ultra-high temperatures enable our system to serve continuous industrial demand for days on end.
3
ALWAYS-ON INDUSTRIAL HEAT & POWER

At these glowing-hot temperatures, the carbon blocks transfer energy as light. This eliminates the need for complex and maintenance-intensive mechanical systems. Energy is discharged 24/7 as heat at the scale and temperatures that large industrial operations demand.

Heat-To-Power Technology

Antora’s thermophotovoltaic (TPV) technology converts light from the hot carbon blocks into electricity with no moving parts. This enables output of both electricity and heat at industrial scale.
