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.
1,000‑year storage
Carbon Removal Commitment
The company is committed to ensuring that carbon removal is permanent, with storage lasting at least 1,000 years.
- Constructed and operated with union labor at Tracy facility — partnering with UA Plumbers & Pipefitters Local 442 and IBEW 595
- Built community governance model with quarterly community feedback meetings in Tracy and San Joaquin County
- Refuse equity funding from companies whose core business is oil and gas, and no CO₂ removed used for enhanced oil recovery
- Founding Board member of Carbon Removal Alliance—committed to additionality, verifiability in carbon removal
1B tons annually
CO₂ Removal Target
The company aims to remove 1 billion tons of CO₂ by 2035, contributing significantly to reducing U.S. emissions.
$150M raised
Series B Funding
Secured $150 million in Series B funding to drive down costs and scale operations.
500K tCO₂ secured
