Brethomé, F.; et al. (2018): Direct air capture of CO2 via aqueous-phase absorption and crystalline-phase release using concentrated solar power

Brethomé, F.; Williams, N.; Seipp, C.; Kidder, M.; Custelcean, R. (2018): Direct air capture of CO2 via aqueous-phase absorption and crystalline-phase release using concentrated solar power. In: Nat. Energy 3 (7), S. 553–559. DOI: 10.1038/s41560-018-0150-z.

„Direct air capture of carbon dioxide offers the prospect of permanently lowering the atmospheric CO₂ concentration, providing that economical and energy-efficient technologies can be developed and deployed on a large scale. Here, we report an approach to direct air capture, at the laboratory scale, using mostly off-the-shelf materials and equipment. First, CO₂ absorption is achieved with readily available and environmentally friendly aqueous amino acid solutions (glycine and sarcosine) using a household humidifier.“
