Over the last decade, the chemical and materials industries have pursued innovative technologies for greater economic efficiency, while also addressing global dialogue regarding controversial measures of carbon footprint. Credible assessment and reporting of such measures will require a paradigm shift in process evaluation and optimization, requiring widely distributed consensus measurement technologies, collection of vast new datasets, and a greater reliance on, and acceptance of, validated models, while simultaneously respecting economic and other feasibility constraints. The National Institute of Standards and Technology (NIST) Material Measurement Laboratory (MML) Carbon Capture, Use, and Storage (CCUS) Program was initiated in FY21 and seeks to acquire and disseminate the necessary technical knowledge to advance U.S. competitiveness in any potential carbon markets. This includes the fundamental measurements and data needed to evaluate detailed chemical and physical processes underlying carbon dioxide capture technologies, and advance credible measurement capabilities, standards, and conformity assessment (accreditation, certification, verification, and validation).
Carbon Capture, Use, and Storage (CCUS) requires a suite of technologies to capture carbon dioxide from industrial point sources, the atmosphere, and the ocean; convert carbon dioxide into products such as fuels, chemical feedstocks, and building materials; and sequester carbon dioxide deep underground in saline aquifers or depleted oil and gas reservoirs. Based on outreach to industry, academia, and Federal partners through workshops, conferences, and working groups, and leveraging the NIST Material Measurement Laboratory (MML) expertise, MML is currently focused on measurements and standardization needs for carbon dioxide removal and carbon sequestration in building materials. To ensure the program continues to meet industry needs and to guide NIST’s pre-standardization research, MML established two consortia that address very different industries at vastly different stages.

Cement and concrete is a long-standing mature industry using well-established codes and standards. However, it recognizes the need for innovative materials to reduce costs and ensure supply chain security, and therefore requires updated codes and standards, as well as reliable metrics for advanced performance. Furthermore, it offers opportunities to increase energy efficiencies, reduce emissions, and create products with captured CO2.
Carbon dioxide removal, capturing CO2 from the atmosphere with durable removal, is a subset of the broader carbon capture industry. In contrast to industrial point source capture where concentrations of CO2 can range from 5 % to 95 %, the CO2 concentration in the atmosphere is 0.04 %. Given the variety and complexity of carbon dioxide removal approaches (engineered, natural, and hybrid pathways), comparable measurements are needed to adequately assess performance and inform decisions. Here, MML is working with stakeholders in this nascent industry to educate, advance measurement capabilities, and navigate early-stage standardization activities.
MML is focused initially on 1) the measurement methods of carbon dioxide sorption kinetics on solid sorbents, 2) the quantification of carbonates in cements and concretes, and 3) next generation seawater reference materials. This research is leading to new measurement tools with well-understood uncertainties. Results are being used to validate models and are disseminated through databases and publications. With this foundation, MML is collaborating with industry partners to understand the level of measurement rigor and reproducibility throughout the R&D ecosystem. MML is developing research grade test materials and comparing measurements through interlaboratory comparisons. Furthermore, measurement methods are being formalized through the voluntary consensus standards process in ASTM.
