• Frontier buyers including Google and Stripe will fund removal of 122,000 tonnes of CO2 via biowaste based CDR between 2026 and 2030.
  • The deal lifts Frontier’s total investment in Canadian climate solutions above $100 million, reinforcing Canada’s role in engineered carbon removal supply.
  • Hydrothermal liquefaction could scale to 1.5 gigatonnes of annual carbon removal by 2040, according to Frontier estimates, if deployment barriers are cleared.

A coalition of corporate climate buyers led by Frontier has agreed to invest $44.2 million in a carbon dioxide removal agreement with Canadian firm NULIFE GreenTech, targeting the removal of 122,000 tonnes of CO2 between 2026 and 2030. Buyers include companies participating in Frontier’s advance market commitment, among them Google and Stripe, as part of a broader effort to accelerate early-stage carbon removal technologies toward commercial scale.

The agreement builds on a partnership launched in 2024, when Frontier became NULIFE’s first buying customer. Since then, the Saskatchewan-based company has already delivered more than half of the total volume contracted under earlier commitments, providing Frontier with operational data and verification history that de-risked a larger follow-on purchase.

For Frontier, this marks its third offtake agreement with a Canadian company. Total capital committed by the coalition to climate solutions in Canada has now surpassed $100 million, underscoring the country’s growing importance in the global engineered carbon removal market.

Turning A Waste Liability Into Permanent Storage

NULIFE’s approach targets a persistent emissions challenge. Biowaste that decomposes in open air releases carbon dioxide and, in some cases, methane. Agricultural and industrial operators often face high costs and logistical hurdles in managing residues such as grease-trap waste from food processors, sludge from canola crushing, biosolids from wastewater treatment, and similar organic byproducts.

Instead of allowing that material to decay, NULIFE uses hydrothermal liquefaction technology to process biowaste into a concentrated bio-oil and biochar. These carbon-dense outputs are transported by truck and injected into underground salt caverns for long-term geological storage at depths of roughly 1,000 meters.

By injecting both bio-oil and biochar together, NULIFE increases overall carbon removal efficiency and durability. Salt caverns, already used in parts of the energy system for hydrocarbon storage, offer a controlled environment for isolating carbon from the atmosphere over extended time horizons.

Commercial Operations And Verification

NULIFE’s Saskatoon facility has logged thousands of operating hours using commercial-scale hydrothermal liquefaction processors. The site has already delivered tonnes of carbon removal credits that have been independently verified by Isometric, providing a level of measurement, reporting, and verification rigor that corporate buyers increasingly demand.

This operational track record is critical for buyers like Frontier, which aims to accelerate learning-by-doing across the carbon removal sector. Early purchases are designed not only to secure future supply but also to surface technical, regulatory, and cost challenges while volumes remain relatively small.

Why Buyers Are Betting On HTL

A key attraction of hydrothermal liquefaction is feedstock flexibility. NULIFE’s system can process a wide range of biowaste types, including dry biomass, woody biomass, crop residues, and wet organic waste. That versatility expands the pool of potential project locations and reduces dependence on any single waste stream.

Frontier estimates that, with sufficient deployment, hydrothermal liquefaction could support up to 1.5 gigatonnes of annual carbon dioxide removal by 2040. Reaching that level would require sustained demand signals from buyers, streamlined permitting for geological storage, and continued advances in cost reduction.

What Executives And Investors Should Watch

For corporate climate leaders, the NULIFE agreement highlights how advance market commitments are shaping the carbon removal landscape. Long-dated offtake contracts provide revenue certainty that enables developers to finance infrastructure, while giving buyers visibility into future supply aligned with net-zero targets.

For investors, Canada’s role in this deal points to a broader trend. Jurisdictions with established industrial infrastructure, supportive policy environments, and access to suitable geological storage are emerging as hubs for engineered carbon removal.

As demand for high-integrity removals intensifies under corporate climate strategies and evolving regulatory scrutiny, deals like this one illustrate how capital, policy, and technology are beginning to align. The outcome will influence not only Canada’s climate economy but also how quickly durable carbon removal becomes a credible pillar of global decarbonization efforts.
