Arbor Energy just landed a billion-dollar order to bring rocket turbine tech to the power grid

Arbor Energy, an energy startup, announced a major deal to supply up to 5 gigawatts of its modular Halcyon turbines to GridMarket, a company facilitating power projects for data centers and industrial users. These turbines leverage rocket turbomachinery technology originally developed for spaceflight and are 3D printed, with each unit generating 25 megawatts. The order could total around 200 units, potentially valued in the single-digit billions of dollars. Arbor plans to connect its first turbine to the grid by 2028 and scale production to over 100 turbines annually by 2030, aiming for an eventual capacity of 10 gigawatts per year. Originally designed to run on biomass—organic waste converted into syngas and burned with pure oxygen to produce carbon-negative power—Arbor has since adapted the Halcyon turbines to also use natural gas. While this increases fuel flexibility, it means the turbines running on fossil fuels will emit some greenhouse gases, though significantly less than
