How it works
A new way to store and use energy
01
Air + electricity = liquid fuel
Prometheus absorbs CO2 from the atmosphere and stores it as carbonate (CO3). Using its proprietary technology, carbonate and electricity are transformed into hydrocarbon fuels.
02
Liquid fuels store energy
When electricity is abundant, Prometheus can store thousands of hours of energy from intermittent renewable sources, making that energy available again for firm, dispatchable power when needed.
03
emissions reabsorbed
When the fuels are used to generate power, the carbon and water from these fuels is recaptured and stored again as carbonate salts in water. This capture can be done at any time, with the carbonate turned into fuel later when energy is abundant again. Near zero emissions.
04
Firm 24/7 Power
The electricity stored in the chemical bonds in the fuel is dispatched, returning the hydrocarbon to water and carbonate again. The principle is similar to batteries that store and release electricity from lithium or iron by changing their oxidation state. We do the same, but with carbon.
