The HyCO2 network: The hydrogenation of CO2 to liquid fuels as the basic technology for the chemical storage of fluctuating renewable energies
Wind and solar energy help to secure a sustainable energy supply. However, their availability is subject to strong fluctuations. Therefore, energy storage becomes increasingly important. Today, hydrogen production using water electrolysis is preferred. Hydrogen, however, cannot be stored easily on a large scale. In order to change this, the pilot project HyCO2 investigates ways in which the electrolysis-hydrogen can, together with carbon dioxide, be converted into easily storable liquid energy carriers. The project is directly integrated into the research area Energy Systems. The goal is to reduce CO2 emissions and to increase the population's security of supply with sustainable energy at the same time.
