Advancements in Direct Air Capture

Expected Outcome: Project results are expected to contribute to the following outcome: Accelerating the commercial availability of Direct Air Capture technologies. Scope: Projects are expected to aim at scaling up existing technical solutions to at least the level of pilot demonstration in relevant environments (TRL 7 or higher). Projects are expected to demonstrate: Improving the cost efficiency of the capture and regeneration process, including Balance of Plant; Improving material performance and process designs (e.g. capture/desorption capacity and kinetics, durability, long-term stability in air); Potential for manufacturing and scale-up (recycling and reuse of materials); Flexible operation under intermittent or surplus renewable energy supply. Depending on the technology, other important issues to address are: Reducing energy use for sorbent/solvent regeneration; Alternative materials for - and approaches to - CO2 separation; Development and demonstration of materials in particular for DAC systems operating in cold temperatures or under humid conditions, or in areas with severe air pollution; Accuracy of simulated predictions compared to validation experiments; New designs for efficient, high-flux air contactors, optimised for maximum air contact. Projects must develop a comprehensive life cycle assessment to evaluate the environmental implications of the entire DAC system, from material extraction and use, energy use and greenhouse gas emissions through to…
