New CO2 capture technologies

Expected Outcome:

Project results are expected to contribute to the following expected outcomes:

• New capture technologies (either from points sources or directly from air) should lead to reduced overall cost of capture, as well as lowest possible negative environmental impact, including water use.

Scope:

Development of new or emerging capture technologies with high potential for cost reduction. Proposals shall address capture of CO₂ either from one of the following areas (and explicitly identify which is being covered):

1. Point sources, or
2. Directly from air (direct air capture, DAC).

Depending on the capture routes chosen (e.g., solvents, sorbents, membranes, cryogenic, solid looping), examples of important issues to address include enhanced absorption/adsorption, improved kinetics and reduced energy use for CO₂ capture and desorption, new materials with high selectivity for CO2 capture, flexibility of operation, modularisation and scale-up, space occupation, degradation and life span of capture materials, ability for retrofit, potential for heat integration, and solvent-induced corrosion.

In particular for DAC, examples of important issues to address are novel sorbent or solvent materials that have higher CO₂ capture capacities and longer-term stability in the presence of heat and air. For all proposals, minimisation of health and environmental impact must be addressed in the project also in view of future scaling up. The developed technologies should aim at delivering CO2 at the specifications required for transport and storage, with very low levels of impurities.

For point-source capture, the technologies should address the performance profile and characteristic when operating under variable operating conditions such as load changes to maintain and as high as possible capture rate across the entire operating profile. Results from point-source capture should provide good matches between specific industrial application and capture technology while guaranteeing the quality and continuity of the industrial process.

The use of the European Research Infrastructure for CO2 Capture, Utilisation, Transport and Storage ECCSEL is encouraged but not mandatory.

In particular for DAC, international cooperation with participating countries of the Mission Innovation Carbon Dioxide Removal Mission^[1] is encouraged.
