Measurement, standards, and data needs for CO2 capture materials: a critical review

Area of Science:

• Materials Science
• Chemical Engineering
• Environmental Science

Background:

• Commercial carbon capture deployment is limited by insufficient materials-related data, standards, and measurements.
• This hinders systematic design, evaluation, and performance assessment of CO2 separation materials.

Purpose of the Study:

• To review the current state of measurements, standards, and data for key carbon capture materials: solvents, solid sorbents, and membranes.
• To identify critical research needs for advancing carbon capture material innovation.

Main Methods:

• Literature search within the carbon capture field.
• Discussions with experts in the carbon capture community.

Main Results:

• Significant gaps exist in standardized evaluation parameters for solid sorbents, despite their potential for cost reduction.
• Lack of in situ experimental tools for structural characterization of porous materials during CO2 adsorption.
• Absence of computational methods supporting a materials-by-design approach for sorbent development.

Conclusions:

• Standardized measurements, data, and advanced characterization tools are crucial for accelerating the development and commercialization of effective carbon capture materials.
• Addressing these needs will enable a more systematic and efficient approach to designing next-generation CO2 separation technologies.
