About
Arbor Energy builds advanced power systems using oxy-combustion and supercritical CO₂ turbomachinery to deliver clean, zero-emission baseload electricity. Founded by veterans of SpaceX's propulsion team, Arbor's modular HALCYON turbine system combusts fuel with pure oxygen and captures all CO₂, enabling carbon-negative electricity when paired with organic waste feedstocks. The technology is designed to be scalable, fuel-flexible, and faster to deploy than competing clean energy alternatives, targeting data centers, industrial facilities, and grid operators seeking reliable carbon-neutral power.
