Breakthrough Energy Ventures, the investment firm financed by billionaires like Jeff Bezos, Bill Gates, and Jack Ma that invests in companies developing technologies to decarbonize society, is investing $12.5 million in a geothermal project development company called Baseload Capital.

Baseload Capital is a project investment firm that provides capital to develop geothermal energy power plants using technology developed by its Swedish parent company, Climeon.

Like the spinoff from Google’s parent company, Alphabet, Dandelion Energy, which recently raised $16 million in a new round of financing, Climeon builds standardized machines to tap geothermal energy. But Dandelion is targeting consumers with its technology to provide home heating, while Climeon turns geothermal energy into electricty.

The company’s modules — which stand around two meters cubed, produce 150 kilowatts of electricity, which is enough to power roughly 250 European households, according to a company spokesperson.

Climeon, which was founded back in 2011, formed Baseload Capital about a year ago to invest in special purpose vehicles to build the power plants that use Climeon’s technology. Baseload takes an equity stake in these companies and provides debt financing for them.

Through its investment into Baseload Capital, Breakthrough Energy Ventures will help finance and develop these small-scale power plants globally (Baseload has already formed special purpose vehicles that are developing projects in Japan).

Climeon and Baseload Capital focus on three primary industries — geothermal, shipping and heavy industry. “We sell our machines to the [maritime industry] where we turn the waste heat from the engines into electricity (Virgin Voyages has bought several systems), to industries such as steel where they also have a lot of waste heat and then to companies that develop and operate geothermal power plants,” a Climeon spokesperson wrote in an email. “This could be a newly formed SPV or an existing energy company. In the U.S., for example, our modules will be used in an existing geothermal site.”

The company’s pitch is that it’s modular units make it easy to scale up or decommission plants. Modules list for EUR350,000 and customers also spend EUR5,000 per-module, per-year on Climeon’s power plant management software.

So far, the company says it has an order backlog of roughly $88 million.

The investment in Baseload Capital is Breakthrough Energy’s second foray into the geothermal industry. Last year, the company backed Fervo Energy, which uses proven technologies to help speed the development of geothermal energy at a cost of 5 to 7 cents per kilowatt hour.

“We believe that a baseload resource such as low temperature geothermal heat power has the potential to transform the energy landscape. Baseload Capital, together with Climeon’s innovative technology, has the potential to deliver GHG-free electricity at large scale, economically and efficiently,” said Carmichael Roberts of Breakthrough Energy Ventures, in a statement.
