Grandpuits Carbon Storage

RepAir Carbon US Inc. and C-Questra’s EU Onshore Carbon Dioxide Removal Project is a pioneering Direct Air Capture and Storage (DACS) initiative in Grandpuits, near Paris, France, intended to become the European Union’s first onshore carbon dioxide removal project that fully integrates capture and permanent geological storage. The partnership combines RepAir’s ultra-efficient, electrochemical DAC technology, which consumes about 70 % less energy than conventional systems and uses only electricity with C-Questra’s carbon storage expertise and development of an onshore CO2 storage site in the Île-de-France region, eliminating the need for costly midstream or offshore infrastructure. The project’s near-term goal is to remove ~100,000 metric tons of CO₂ per year from the atmosphere by 2030, with plans to scale toward megaton-level CO₂ removal by around 2035, supporting the EU’s broader decarbonization strategy. By co-locating capture and storage operations, the collaboration aims to streamline deployment, reduce costs, and enable local manufacturing and green job creation. RepAir’s modular DAC units can also be adapted to capture CO₂ from diluted industrial point sources, broadening potential impact beyond atmospheric removal.
