AirMyne taps geothermal energy to scale direct air carbon capture
Because of the quirks of the chemical reaction involved, high-temperature regeneration cycles can be more efficient. But heat that intense can be hard to come by, which is why AirMyne developed its liquid to regenerate, or release its CO2, using low-temperature heat that’s just 100-130 degrees C (212-266 degrees F).
AirMyne’s low-temperature heat requirements mean its overall process could prove to be less efficient than a high-temperature approach, but co-founder and COO Mark Cyffka believes it gives his company a better chance to grow and scale.
In 2026, AirMyne is planning to deploy its carbon capture technology to a sequestration site in San Joaquin County, California, where it will be injected underground. To get there, the company recently raised a $6.9 million seed round, TechCrunch has exclusively learned. Investors in the round included Alumni Ventures, Another Brain, Liquid 2 Ventures, EMLES, angel investor Justin Hamilton, Impact Science Ventures, Soma Capital, Wayfinder and Y Combinator.
