Senken and Carbonsate sign 50,000-tonne biomass storage offtake for Namibian project

Berlin-based carbon credit platform Senken signed a multi-year offtake agreement with Carbonsate for 50,000 tonnes of certified carbon removal credits from 2026 to 2028 vintages. This represents the largest biomass geological storage commitment by a European buyer and the largest worldwide for an African project. Carbonsate's Namibian project addresses encroacher bush by burying harvested wood in engineered underground chambers, preventing decay and sequestering carbon for centuries. The agreement provides Carbonsate with revenue certainty to scale operations beyond 100,000 tonnes per year, with deliveries commencing in 2026. Credits are independently verified under the Puro.earth standard, offering European corporate buyers access to high-integrity carbon removal.
