Critical Energy designs and manufactures modular turbines and turbomachinery aimed at speeding deployment of geothermal power plants. The company leverages founder Spencer Jackson's SpaceX turbomachinery experience to produce factory-built modules that can be assembled faster than large, site-assembled turbines. Its immediate plan is to build a 2.5 megawatt turbine module as its first project, with a 5 megawatt module in development for enhanced geothermal operators. The first plant using its turbines is slated for completion by 2027. Financially, Critical Energy has raised $19 million in seed equity and $3 million in venture debt, totaling $22 million in early capital. The company projects rapid scaling, targeting gigawatt-scale output by the early 2030s and a long-term goal of producing 300 gigawatts of capacity per year by 2045.
