Frontier, the carbon removal initiative backed by Stripe, Alphabet, Shopify, Meta, McKinsey, and other corporate partners, has signed a $44.2 million offtake agreement with Canadian biowaste specialist NULIFE GreenTech to remove 122,000 tonnes of CO₂ between 2026 and 2030.
The CO₂ will be captured from agricultural and industrial residues and stored underground as concentrated bio-oil in licensed salt caverns, marking Frontier’s third carbon removal deal in Canada and bringing its national commitment above $100 million.
NULIFE employs hydrothermal liquefaction (HTL) to convert grease-trap waste, wastewater sludge, and other organic residues into carbon-rich bio-oil and biochar. The bio-oil is then injected roughly 1,000 meters underground for permanent storage.
The modular HTL units are designed for scalable deployment, supporting rapid replication across Canada and internationally. Frontier estimates that HTL technology could potentially remove up to 1.5 gigatons of CO₂ annually by 2040, highlighting its potential contribution to large-scale climate mitigation efforts.
The agreement exemplifies a growing focus on turning everyday waste streams into verifiable, long-term carbon removal solutions. Frontier’s founding and partner members, including Stripe, Google, Shopify, McKinsey Sustainability, Autodesk, H&M Group, and Workday, have actively engaged in such transactions, reflecting rising corporate demand for tangible, scalable carbon removal.
