If climate change mitigation is based on energy crops, the impact of carbon dioxide removal (CDR) on area demand may be significant. The CDR-specific area demand is usually not presented. This study compares a CDR technology portfolio prioritising biomass-based solutions to portfolios prioritising low cost, low energy demand, high security, low area demand, and high technology readiness in terms of area demand. The CDR portfolio model is linked with an energy system model to include the area required for solar photovoltaics and wind power for the energy supply of the whole energy–industry–CDR system.
