Phlair (formerly Carbon Atlantis) is a Direct Air Capture (DAC) company included in the Frontier Climate portfolio, specializing in a novel electrochemical approach to permanently remove carbon dioxide from the atmosphere. By utilizing a proprietary “hydrolyzer” technology, Phlair replaces the energy-intensive thermal heat typically required in DAC with an all-electric, solvent-based system. This design allows the company to leverage low-cost, intermittent renewable energy to capture carbon efficiently.
Phlair’s technology utilizes a “solvent looping” process driven by a hydrolyzer, which acts as the system’s engine. The process involves three main steps:
Capture: Fans draw ambient air into the system, where it flows over a high-pH liquid solvent (base). This solvent selectively binds with the CO2 in the air.
Release (pH Swing): Once the solvent is saturated with carbon, it is mixed with a low-pH acid. This sudden change in acidity (a “pH swing”) forces the liquid to release the trapped CO2 as a pure gas, which is then collected for storage.
Regeneration: The key innovation is the hydrolyzer, which uses electricity to continuously split a salt solution back into the acid and base needed for the capture and release steps. Uniquely, Phlair can “overproduce” these fluids when renewable energy is cheap and abundant, storing them in tanks to keep the system running when energy prices are high. This allows the facility to act like a giant chemical battery, decoupling operations from real-time energy availability.
Phlair secured a significant partnership with Frontier buyers through a $30.6 million offtake agreement. Under this contract, Phlair will deliver 47,000 tons of carbon removal between 2027 and 2030. This agreement supports the development of “Project Dawn,” Phlair’s first commercial-scale facility located in Alberta, Canada.
Phlair’s modular design allows for rapid scaling by utilizing off-the-shelf components from the fuel cell and water treatment industries. The company has progressed quickly from lab-scale prototypes to outdoor pilots (such as “Electra”) and is now advancing toward commercial deployment with Project Dawn, which will have a capacity of over 15,000 tons per year. The carbon captured at this facility will be permanently sequestered underground in geological formations. Phlair is also developing projects in Norway to leverage local renewable grids and storage infrastructure.
Phlair aims to drive the cost of carbon removal to under $100 per ton by achieving high energy efficiency—targeting less than 1.5 MWh per ton. By eliminating the need for thermal heat and relying on standardized, mass-manufacturable electrochemical cells, the company is positioned to scale rapidly. Phlair projects its technology could contribute significantly to the gigaton-scale removal capacity required by 2050.
