Researchers from the University of Tokyo have introduced a novel technique to quantify CO2 absorbed by concrete, utilizing isotopic ratio analysis. The method addresses the challenge of distinguishing between fossil-derived and atmospheric CO2, critical for accurate carbon accounting in carbon capture technologies.
The approach employs a correction model for isotope fractionation effects, improving source attribution accuracy. Field validation in industrial settings is planned to confirm robustness before commercialization.
This work is part of a strategic initiative funded by Japan's NEDO, emphasizing the importance of sustainable materials science in climate action. The potential impacts include improved regulatory frameworks and enhanced carbon markets, marking a significant step in the transition to carbon neutrality.
