DeltaSpark receives CHF 150,000 from Venture Kick to turn CO2 into clean hydrogen and solid materials
31.03.2026
The EPFL spin-off DeltaSparks has obtained CHF 150,000 from Venture Kick to advance a technology that converts CO2 into stable minerals while producing cheap and clean hydrogen on-site. The cleantech startup aims to help industries reduce emissions while generating valuable byproducts.

Record-high CO2 emissions are driving global warming and increasing pressure on industries to reduce their carbon footprint. Sectors such as cement, waste-to-energy, and heavy manufacturing face particular challenges, as their emissions are difficult to eliminate. Current carbon capture solutions often store CO2 without creating additional value, limiting their economic attractiveness.
This is where DeltaSpark steps in, creating a compact system that converts CO2 into solid, stable minerals. Using an electrocatalytic process, the technology simultaneously produces clean hydrogen and oxygen on-site. By turning emissions into useful resources, the approach offers industries a way to reduce carbon output while generating chemicals and materials.
DeltaSpark uses a patented electrocatalytic process in modular shipping containers to mineralize CO2 into building materials while producing valuable chemicals like low-cost clean hydrogen, oxygen, and green sulfuric acid. Its mineralization is up to 100× faster than existing methods, offering the only solution that combines cost-effective CO2 removal with local clean H2 production without relying on carbon credits. DeltaSpark’s CO2-offset subscription (“Carbon Removal as a Service”) is priced below carbon taxes, allowing large emitters, such as cement plants and incinerators, to cut CO2 liabilities while gaining strategic access to high-value chemicals.
The CHF 150,000 from Venture Kick will enable DeltaSpark to accelerate the delivery of its paid pilots and support its seed fundraising round in the next months.
DeltaSpark was founded by CEO Dr. Luc Bondaz and CTO Dr. Suhas Nuggehalli Sampathkumar, who met during the EPFL PhD Excellence Program. Supported by advisors with expertise in scale-up and process engineering, the team combines technical and industrial knowledge to bring carbon conversion solutions to market.
“Venture Kick is more than just funding. It also provided us with essential coaching that helped us refine our business plan for our target customer segments,” highlights CEO Luc Bondaz. “Through this support, we were able to capture our customers’ needs, sharpen our value proposition, and develop a clear go-to-market strategy.”
