Rodatherm Energy, a new geothermal startup, emerged from stealth Monday with $38 million in funding and a plan to build a pilot plan in Utah.\u00a0<\/p>\n
The startup differentiates itself by plumbing its boreholes with a closed loop, likely made of steel, that\u2019s filled with a refrigerant. That contrasts with other enhanced geothermal companies, which tend to use water to transport heat from deep within the Earth.<\/p>\n
The Series A round was led by Evok\u00a0Innovations with participation from Active Impact Investments, Giga Investments, Grantham Foundation for the Protection of the Environment, MCJ, TDK Ventures, Tech Energy Ventures, and Toyota Ventures.<\/p>\n
Rodatherm faces stiff competition with an established field of players, including Fervo Energy, Sage Geosystems, XGS Energy, and Quaise.<\/p>\n
Fervo is considered the frontrunner in the space having raised nearly $1 billion. The company is on track to complete a 100-megawatt first phase of its Cape Station power plant next year with an additional 400 megawatts coming online in 2028. It also has a deal to supply Google with electricity for its data centers. XGS Energy also has a data center deal, one with Meta, to develop a 150-megawatt power plant in New Mexico to power the tech company\u2019s data centers.<\/p>\n
Rodatherm says that its closed-loop, refrigerant-based approach is 50% more efficient than a typical water-based system. Air-source heat pumps, commonly called minisplits, use hydrocarbon-based refrigerants to shift heat between indoors and out.<\/p>\n
The startup\u2019s patent on the technology says that the closed-loop design will eliminate the need for filters to screen grit and debris that open-loop systems might suck up as the water flowing through the ground breaks bits of rock loose. It also says that the closed loop system will minimize water use.<\/p>\n

\n\t\t\t\t\t\t\t\t\tSan Francisco<\/span> But Rodatherm\u2019s approach will almost certainly come with increased drilling and installation costs relative to simpler systems. It\u2019s possible that the added efficiency its refrigerant-based design could offset those costs, though that remains an open question until the company completes a well.<\/p>\n The company plans to use the Series A funding to complete a small pilot 1.8-megawatt pilot plant in Utah by the end of 2026. Utah Associated Municipal Power Systems plans to buy electricity from the project.<\/p>\n","protected":false},"excerpt":{"rendered":" Rodatherm Energy, a new geothermal startup, emerged from stealth Monday with $38 million in funding and a plan to build a pilot plan in Utah.\u00a0 The startup differentiates itself by plumbing its boreholes with a closed loop, likely made of steel, that\u2019s filled with a refrigerant.
