Novel Geothermal Energy Systems

German technology startup Factor2 Energy has secured venture capital funding to advance a novel geothermal energy system that utilizes carbon dioxide as its primary working fluid. Historically, these solutions have utilized conventional water or brine. Factor2 Energy has developed a process where CO₂ is injected into underground geological formations, where it absorbs heat and naturally circulates back to the surface through thermal buoyancy. In doing so, the process eliminates the need for energy-intensive pumping systems. This heated CO₂ then drives a specialized turbine to generate electricity before being reinjected underground, resulting in a continuous closed-loop system that simultaneously produces power and maintains carbon storage. Factor2 Energy's novel geothermal energy system claims to potentially double the power output compared to traditional solutions under similar conditions.
