Summary
Antora Energy is deploying a 200-unit thermal battery system in South Dakota, partnering with Grok Ventures to supply heat to Poet's ethanol bioprocessing plant. The system uses a novel electricity rate structure to make thermal energy storage economically competitive, replacing steam currently supplied by a nearby 475-MW coal power plant. The project represents a breakthrough in industrial decarbonization by using low-cost electricity to store thermal energy for industrial heat applications.
Key quotes
· 3 pulledThe batteries will pipe steam over the fence to the bioprocessing plant, which uses copious amounts of low-temperature heat to turn corn into ethanol.
Right now, at least some of that steam comes from boilers inside the 475-MW coal power plant that Otter Tail operates next door.
The novel electricity rate is key to allowing Antora to deliver competitive thermal energy storage.
