Reimagining Geothermal Energy with CO₂ At Factor2 Energy, we are pioneering a new generation of geothermal technology. Our approach uses CO₂ as the working fluid in geothermal power generation – enabling emission-free, efficient, and baseload-capable electricity. By repurposing geological formations that either naturally contain CO₂ or are designated for carbon capture and storage (CCS), we transform passive storage sites into active, sustainable energy resources. Our technology leverages the unique thermophysical properties of CO₂ to unlock significantly more viable sites than conventional geothermal – without fracking, without new drilling technologies, and by building on existing infrastructure and know-how.

autarkize scales a market-ready system technology with which a high-quality gas made of methane and hydrogen is obtained decentrally from residues (wood residues, fermentation residues, sewage sludge, ...), which contains 3-4x more energy density than previous processes. This gas is suitable as a replacement for natural gas or green hydrogen for almost all common processes for generating electricity and heat. At the same time, the plants produce biochar - a valuable soil conditioner for agriculture and a permanent CO2 sink. The reachable climate impact exceeds 500 mt/a of GHG reduction and carbon dioxide removal.

Lithium-ion batteries are widely used, but they are not ideal for all applications. They are relatively slow to recharge, flammable, and temperature-sensitive. BTRY, an EMPA- and ETHZ- spinoff, is developing a new type of thin-film solid-state battery. It can be charged and discharged in one minute, has a high energy density, and delivers reliable energy even at extreme temperatures.
