Shape the Future of Climate Tech with Phlair!

Fossil fuels have powered our economy for decades—at the cost of pollution and a changing climate. At Phlair, we’re reversing that equation. With our cost-efficient, scalable electrochemical Direct Air Capture (DAC) technology, we pull CO₂ from the air to either store it permanently or repurpose it into CO₂-negative chemicals. Join us in enabling a carbon-negative future.

Why We’re Different?

We’ve developed a breakthrough hydrolizer for acid/base regeneration, enabling scalable CO₂ capture. With partners like Frontier Climate, Stripe, and Shopify, we’re on track to make a global impact.

Our Project Dawn is our flagship initiative, setting the foundation to scale our technology and remove CO₂ from the atmosphere. We're one of the only seven DAC companies with a proven offtake agreement. Phlair is poised to become a technology leader, leveraging renewable energy and low-cost DAC to provide clean energy solutions that go beyond carbon removal.
