The minute
- Senken, a Berlin-based carbon credit procurement platform, and Carbonsate, a Berlin-based CO2 removal technology company, signed a multi-year deal for 50,000 tonnes of permanent carbon removal
- It is described as the largest biomass storage deal signed in Europe to date, and the second-largest buyer commitment in biomass geological storage globally
- The credits come from burying waste wood in sealed underground chambers in Namibia, a method that avoids the energy-intensive steps of direct air capture, with deliveries running 2026 through 2028
Why it matters: Biomass geological storage skips the most expensive part of engineered carbon removal, the capture step, since the wood has already pulled the carbon out of the air by growing. That is what lets a deal this size undercut direct air capture on price while still delivering permanent removal.
Every storage site uses a proprietary monitoring and verification system independently checked under the Puro.earth standard, the same kind of third-party layer that separates a durable removal credit from one that collapses under scrutiny. via ESG Today
