Zero-carbon industrial heat company Rondo Energy has launched two commercial models of its Rondo Heat Battery, which uses electric heating elements, such as a toaster or oven, to generate clean electricity. to high temperature heat. Rondo said that its heat battery is a drop-in replacement for the fossil-fired boiler.
The Rondo Heat Battery captures intermittent electricity from solar and wind, stores the energy from that electricity as high temperature heat in brick materials, and delivers the stored energy on demand as high temperature heat and/or or electricity.
The battery, made only of brick and steel, charges in four hours and stores heat energy at temperatures up to 1500C for hours or days, delivering zero-carbon heat for processes. such as steel, cement, chemical manufacturing, and low temperature food processing.
Rondo, which is backed by Bill Gates-founded Breakthrough Energy Ventures and utility-backed Energy Impact Partners, says its Heat Batteries maintain continuous output power (95% annual capacity factor) while operating at input power of less than 15% capacity factor ( four hours a day). It also states that one RHB300 eliminates more than 40,000 tons of CO2 per year – more than 8,700 electric vehicles eliminate.
Just replacing the industrial heat currently used in California with RHB zero-carbon heat would eliminate five times more CO2 than all the EVs on the road in the US today – 13.6 million EVs.
Carmichael Roberts, Breakthrough Energy Ventures, said:
The Rondo Heat Battery can prove critical in eliminating emissions, and its commercial availability will help companies return to zero carbon heat for their processes.
The Rondo Heat Battery helps companies in industries such as cement, fuel, food and water desalination to start taking advantage of the reduced costs of renewables without changing their facilities.
The Oakland-based company says the battery models available now, the RHB100 and RHB300, are fully automatic, charging intermittently from local wind or solar facilities or from the grid, and delivering on demand 24 hours a day.
Rondo manufactures its batteries at its facilities in California and has begun commercial deliveries.
