One of the key challenges of CCU is achieving energy-efficient and cost-effective CO₂ capture. Today’s amine-based carbon capture systems still depend largely on fossil-derived heat for solvent regeneration, reducing their overall climate benefit.
In a new study by our member, the German Aerospace Center (DLR), published in the peer-reviewed journal Carbon Capture Science & Technology, the authors Shashank Singh Rawat, Frederico G. Fonseca, and María Isabel Roldán Serrano explore a cost-effective pathway to decarbonise amine-based CO₂ capture by:
-
Modelling the Technology Centre Mongstad (2015) MEA campaign, treating flue gas from a natural gas CHP plant
-
Performing a techno-economic assessment using Aspen Plus™ on an industrial pilot capture unit
-
Integrating a high-temperature heat pump, cutting external heat demand by 27% with only minor process modifications
-
Demonstrating the strong impact of working fluid choice and stripper pressure on energy and cost performance
The work shows that electrified and heat-integrated carbon capture is a realistic option today and provides valuable insights for researchers, technology providers, and policymakers working to reduce emissions in energy-intensive industries.
