On the one hand, carbon dioxide (CO2) is a gas which is harmful to the environment. However, it can also be used as a resource – for example for plastics or renewable fuels – and could replace fossil natural gas and crude oil in future. The extraction of CO2 from the air can play a role in the fight against climate change in several ways: It reduces the concentration of the greenhouse gas in the atmosphere, converts it to a usable form for the chemical industry and regenerative mobility, and will lead to a drastic reduction in emissions in future.

One aim of the project entitled “CORAL = CO2 as a raw material from the air” is to develop a highly efficient procedure to extract CO2 from air. This serves as the basis for generating renewable raw materials from electrolytically produced hydrogen and CO2 in the air using material flows and waste heat from electrolysis and synthesis.
