C+UP’s breakthrough technology captures and converts CO2 into sustainable eFuels and eChemicals, such as propane, using renewable electricity and water. This technology offers an economically viable solution for CO2 upcycling, contributing to a circular carbon economy and reducing dependency on fossil fuels. Sustainable propane can serve as a feedstock for petrochemical processes to produce propylene or ethylene—the building blocks of plastics, tires, fibers, and rubbers essential to modern life. Alternatively, it can be used as a sustainable alternative fuel, replacing gasoline and diesel.
