STDAC: Integrated Solar Thermal Direct Air Capture for negative CO₂ emissions
Published:
Removing CO₂ from the atmosphere is important for stopping climate change. Direct Air Capture currently requires too much energy to be economically feasible. In this project, we develop new integrated process in which solar radiation is captured as heat, and used directly to filter CO₂ from the air. Using a multiscale modelling approach, we investigate the influence of changing weather conditions on the process, as well as the expected costs for CO₂ removal. This study will yield a novel optimised STDAC process design and reliable data on the potential scale and costs per net tonne CO₂ removed from the atmosphere. These will be of great value for growing DAC, as well as for integrated assessment models used to design future energy systems.
