Geothermal developer 400C has acquired an existing geothermal well in Salt Cove, Utah to demonstrate their superhot-capable stimulation technology.
400C Energy, a tech-enabled enhanced geothermal developer, is pleased to announce the acquisition of an existing well in Utah, nearby the DOE FORGE project. The company will demonstrate its superhot-capable stimulation technology in this pilot well, offering a scalable and globally deployable solution for 24/7 carbon-free power.
400C Energy aims to develop a 275 °C pilot well pair with 100 kg/s of sustained flow rate, representing nearly 20 MWe of power output – which would be a record breaking EGS well pair.
This announcement follows recent news of the company acquiring 1960 acres of geothermal exploration rights in Salt Cove, Utah.
“We are excited with the acquisition of this asset as it will allow us to demonstrate our EGS technology at a much lower capital requirement. We’re optimistic that the first pilot deployment of our tech will provide a step-change increase in power output. It’s critical that we have a technical breakthrough in EGS to attract much needed capital and developers to the geothermal industry,” said Blake Wood of 400C.
“Next-gen enhanced geothermal is a significant contender for clean firm power generation – the Western US has vast resources of Tier-1 dry, hot rock waiting to be unlocked with our superhot-capable technology.”
400C’s proprietary stimulation technology is rated to over 400 °C and incorporates flow control devices into the injection and production wells to improve power output and increase the life of the reservoir.
