Supercritical raises new round to bridge carbon removal's supply gap

The capital will fund the company's supply development programme — helping early-stage carbon removal projects move from engineering design to signed commercial deals.
Supercritical has facilitated nearly 2 million tonnes of carbon removal for over 200 buyers and tracks more than 600 suppliers across what it says is 80% of the global durable carbon dioxide removal (CDR) market. Its largest deal to date: a ten-year, one-million-tonne biochar offtake, the biggest US biochar agreement on record.
Why now? Corporate demand for permanent carbon removal is growing as 2029 compliance markets approach, but the pipeline of projects that meet buyer standards isn't keeping up. Supercritical says its marketplace data gives it a clear view of where supply falls short.
The company works across biochar, enhanced rock weathering, direct air capture, mineralisation, BECCS, and other permanent pathways. Its scientific vetting protocol rejects 88% of projects assessed.
What could go wrong? Carbon removal remains a nascent market where project economics are fragile and technology risk is high. Bridging the gap between a promising idea and a bankable deal requires detailed engineering plans, lifecycle assessments, audit-ready measurement, reporting and verification (MRV), and commercial structures that survive corporate due diligence — a long, expensive process with no guaranteed outcomes.
If compliance deadlines shift or corporate appetite cools, the demand that underpins Supercritical's model could soften.
The signal: This round sees Greencode Ventures, a climate-focused fund, leading alongside a returning syndicate of generalist heavyweights — Lightspeed Venture Partners, RTP Global, and LocalGlobe — suggesting that investor conviction in carbon removal is moving beyond deep-tech bets on removal hardware toward the commercial infrastructure that turns projects into contracts. With compliance market deadlines approaching in 2029 and Supercritical claiming visibility over 80% of the global durable CDR market, the company is positioning itself as a gatekeeping layer that could influence which removal pathways attract financing at scale.
