Arbor Energy

Rocket engineering for power generation.

Arbor is a next-generation turbine company using rocket engineering to deliver clean firm power. Rocket engines generate enormous power out of very small volumes. Arbor applies that approach to power generation, using supercritical CO₂ to deliver the same power from a turbine roughly one-tenth the size of a conventional one. Turbine engineering supplies the materials and cooling a power system needs to run continuously for decades. Arbor’s power system, HALCYON, uses oxy-combustion—burning fuel in pure oxygen—to eliminate NOx, SOx, and particulate emissions. This process enables CO₂ to be captured directly from the fuel and stored permanently underground. It also produces water, so a plant can operate without drawing on local water supplies. Each HALCYON unit delivers 25 MW, and units can run independently or get combined into plants of 100 MW and more as demand grows. Components are additively manufactured on standard 3D printers, offering a path outside the legacy supply chains th
