This week, Arbor Energy raised a $55 million Series A led by Lowercarbon Capital and Voyager Ventures on the heels of a partial pivot. Its power plant, rather than sticking to a strict vegetarian diet, is going to be more of an omnivore, capable of burning natural gas in addition to biomass. 

Arbor Energy has raised a $55 million Series A for technology that runs on natural gas and can provide always-available, carbon-free electricity. The startup's technology combusts fuel with a stream of oxygen and creates supercritical carbon dioxide to spin a turbine, with the CO2 then captured and stored.

We’ve raised $55M to complete the demonstration of our modular, zero-emission turbine ahead of commercial deployment.

Arbor has landed a $41 million offtake agreement from the Frontier coalition, in one of the advanced market commitment’s largest such deals to date. The contract will help fund Arbor’s first commercial-scale facility in Louisiana, which is expected to come online in 2028.

Frontier, the organization backed by Stripe, Google, and Meta, announced it is paying Arbor Energy to remove 116,000 tons of carbon dioxide by the end of the decade. The deal gives Arbor $41 million to help it build its first commercial-scale power plant in southern Louisiana that will generate electricity for a data center.

Arbor today announced a contract to deliver 25,000 tons of permanent carbon dioxide removal to Microsoft. Starting in 2027, Arbor will support Microsoft’s climate goals by delivering 5,000 tons of carbon removal per year while generating enough clean electricity to power thousands of homes.
