AirMyne builds a liquid sorbent direct air capture (DAC) system that releases captured CO2 using low‑temperature heat (about 100–130°C). The company’s approach centers on a proprietary chemistry and modular collectors that feed a large, centralized regeneration column similar to those in chemical plants. AirMyne is testing roughly 30 prototypes and has sent captured CO2 samples to CarbonBuilt and Rubi for downstream use. The process requires substantial water — roughly one to seven tons of water per ton of CO2 captured — which may limit deployment in arid regions. The company is exploring pairing its system with geothermal projects and is working with Fervo on a project in Utah. AirMyne plans a 2026 deployment to inject CO2 at a sequestration site in San Joaquin County, California. An update in the article clarifies the company’s chemistry uses an inorganic ionic base, promoters, and a phase transfer catalyst rather than quaternary ammonium compounds.
