We have developed a break-through direct air capture technology that turns ambient air into green hydro-carbons to free the world from fossil fuels. By eliminating CO2 from the atmosphere, we contribute to avoiding the climate crisis. The process consists of 3 main process steps. Absorption in liquid sorbent solution, precipitation as hydrogen carbonate and desorption by either alkali water electrolysis, in which case hydrogen is produced as by-product, or via thermal, low calorific waste heat. Based on 15 years of research GCT was founded as a university spin-out by 2 serial entrepreneurs and an experienced DAC researcher. The company is based in Essen – in the heart of industrial Germany – surrounded by leading technical universities and global chemical, industrial and energy companies.
