What happened

Lowercarbon Capital and Voyager Ventures co-led. The company names itself Arbor Energy.

Kumo note

Arbor sells power first and carbon removal second, and the round was raised on data centre demand rather than on the removal credits. A refiner sits alongside the climate funds in the same equity round.
