Company
Overview
Captures ~1,000 tons/year
CO₂ Removal Capacity
The company operates North America's first commercial direct air capture (DAC) plant in California, capable of removing approximately 1,000 tons of CO₂ annually.
$150 Million
Series B Funding
The company secured $150 million in Series B funding, backed by major climate investors, to expand its operations and partnerships.
1 Million Tons Annually
Project Cypress Target
As part of the Department of Energy-supported Project Cypress DAC hub, the company aims to remove up to 1 million tons of CO₂ annually in Louisiana.
Founded in 2020 by climate-focused engineers, the company harnesses limestone’s natural CO₂ absorption to build modular direct air capture systems.
In late 2023 it launched North America’s first commercial DAC plant in California.
It’s part of a Department of Energy-supported Project Cypress DAC hub in Louisiana.
The process accelerates natural carbon mineralization: limestone is cycled through a renewable-kiln and exposed trays to absorb CO₂ in days.
Captured CO₂ is either sequestered underground or permanently embedded in concrete, forming a sustainable ‘DAC-to-concrete’ pathway.
By leveraging abundant limestone and renewables, the company is pursuing one of the lowest-cost, gigaton-scale carbon removal solutions.
Backed by major climate investors and a $150 million Series B round, it secured commercial offtake deals with Microsoft, Stripe, Meta, Shopify and United Airlines.
A standout fact: their California facility was unveiled with Energy Secretary Granholm and California Lieutenant Governor in attendance.
