C-Questra B.V., the independent developer of sovereign onshore CO₂ storage hubs, and RepAir Carbon, pioneer of ultra-efficient electrochemical carbon capture technology, announced the expansion of their partnership across Europe, with a particular focus on France, the United Kingdom and Poland where C-Questra is currently active.
Under the Addendum to their Memorandum of Understanding, the collaboration now extends beyond Direct Air Capture to include industrial point-source capture using RepAir’s proprietary electrochemical technology, particularly for diluted emissions containing 0-5% CO₂.
RepAir’s unique electrochemical technology, which consumes 70% less energy than conventional methods, enables cost-effective capture of diluted CO₂ sources where existing technologies face prohibitive energy penalties.
This breakthrough addresses a gigaton-scale opportunity for industries such as:
– Aluminium smelters – targeting process emissions at ~1% CO₂ concentration, with aluminium smelting accounting for approximately 300 million tonnes of CO₂ globally.
– Gas turbine power generation – critical for the AI boom and data centre expansion, where RepAir’s instant start/stop capability preserves operational flexibility while capturing 85-90% of emissions.
Combined with C-Questra’s phased onshore storage hubs, this creates one of the first end-to-end, capture-to-permanent-storage offerings for European emitters – delivering a complete net-zero solution with reduced infrastructure requirements, shortening timelines, and reinforcing the EU’s sovereignty in carbon management.
The two companies will:
– Continue developing Direct Air Capture projects while also jointly map and prioritise industrial emitters across Europe.
– Develop pilot projects integrating RepAir’s modular capture systems with C-Questra’s future permanent sequestration sites in France, the UK, and Poland.
– Provide industrial emitters with a bankable pathway to compliance under EU ETS, CBAM, and NZIA frameworks.
Walid Sinno, CEO of C-Questra said: “Europe’s industries urgently need affordable and sovereign access to CO₂ storage. By joining forces with RepAir, we are extending solutions from direct air capture to industrial emissions – helping emitters secure a reliable and competitive path to permanent sequestration.”
Amir Shiner, CEO of RepAir added: “Our electrochemical technology’s ability to efficiently capture CO₂ from air has proven its versatility can extend to diluted industrial sources up to five per cent concentration. This expansion with C-Questra allows us to address both carbon removal through DAC and emission reduction at industrial sites – and to ensure every tonne we capture is permanently and safely stored underground.”
