Frontier Backs Phlair’s Next-Gen Direct Air Capture with $30.6M Investment

A Game-Changer for Carbon Removal Technology

In a major push for energy-efficient carbon removal, the Frontier Commitment is investing $30.6 million in Phlair, a company pioneering electrochemical direct air capture (DAC). The funding will support the removal of 47,000 tons of CO2 between 2027 and 2030, marking the first time Frontier buyers have backed electrochemical DAC technology.

Phlair's unique approach is what set it apart. Instead of relying on conventional high-energy thermal processes, Phlair uses an all-electric system that extracts CO2 from the air without heating. This innovation dramatically reduces both construction costs and energy demand, making DAC more viable on a large scale.

How Phlair’s Technology Works

Phlair's breakthrough lies in its hydrogen-looping electrolyzer, which captures and releases carbon dioxide through electrochemistry rather than thermochemistry. This process eliminates the need for heat, significantly lowering energy consumption and operating costs.

A key feature of Phlair’s system is its ability to synchronize with renewable energy sources. It runs at peak efficiency during high solar output hours and stores excess capture and release liquid in water tanks. These tanks act as a kind of battery, allowing the system to continue operating when the sun goes down, avoiding expensive peak-hour electricity rates.

The Impact of Frontier’s Investment

This investment will help fund Project Dawn, Phlair’s first commercial-scale DAC facility, set to be built in Alberta, Canada. The facility aims to prove that Phlair’s electrochemical approach can scale efficiently while keeping costs low.

Phlair’s ultimate goal is to lower energy consumption to below 1.5 MWh per ton of CO2, a significant improvement compared to traditional DAC systems. If achieved, this efficiency would translate into approximately $15 per ton in cost savings, bringing Phlair closer to its target price of $100 per ton of CO2 removal.

Why This Matters for the Future of DAC

The carbon removal industry has long struggled with high energy demands and operational costs. Traditional DAC technologies rely on high-heat processes, making them expensive and energy-intensive. Phlair’s electrochemical method represents a crucial shift toward affordable and scalable DAC.

Frontier’s backing signals growing confidence in Phlair’s approach, potentially paving the way for broader adoption of electrochemical DAC. The company is also one of the first to integrate behind-the-meter solar power into its operations, further cutting costs and emissions.

With global efforts to meet net-zero targets accelerating, investments in breakthrough carbon removal solutions like Phlair’s could be a turning point for the industry. By combining cost efficiency, renewable energy integration, and innovative engineering, Phlair is positioning itself as a leader in the next generation of carbon capture technology.

The race to scale DAC is on, and with major financial backing, Phlair is now well-equipped to make a lasting impact.
