Abstract This study assesses a theoretical carbon dioxide capture and utilisation (CCU) potential for a broad spectrum of 55 CCU pathways for Germany in 2030, encompassing direct utilisation of CO2 for biomass cultivation or in techno-physical processes and its conversion to energy carriers, chemicals and inorganic carbonates. For each good or production process that could technically substitute fossil carbon sources by renewable ones, Germany-specific production data is collected and combined with its corresponding CO2 conversion factors. By doing so, theoretical potentials for CO2 consumption are determined per pathway, aggregated to a total theoretical CO2 demand, which is then compared to German CO2 emissions, as a proxy for potential CO2 supply. The results show that the theoretical CO2 demand of all considered CCU pathways amounts to about 234–423 Mt CO2 p.a. in 2030 including energy carriers representing the largest share of more than 75 %. This theoretical demand exceeds the potential CO2 provision from possible biogenic and industrial point sources. Considering exclusively CCU pathways, being technologically mature at present state, only 9–13 Mt CO2 p.a. could be consumed in 2030, but a large variety of CCU pathways showing high consumption potentials are close to market maturity.
