DeltaSpark: turning CO₂ into a raw material

When we hear CO₂, we tend to think of climate change and pollution. And rightly so: too much carbon dioxide puts a strain on our planet as it warms the climate. But what if we look at the substance from a different perspective? What if CO₂ could be a valuable resource rather than just a problem?

Starting at the source

DeltaSpark addresses these questions by combining CO₂ storage with hydrogen production. Its solution starts with industrial waste gases, where CO₂ is produced in high concentrations. DeltaSpark’s technology uses an electrochemical process to convert CO₂ into stable minerals that can be used, for example, to produce climate-friendly building materials. This also produces clean hydrogen, which can be used as an energy source. With support from Migros Pioneer Fund, the process will be tested with pilot customers and prepared for market entry.

From a climate problem to a resource

DeltaSpark creates a carbon cycle by converting emissions into useful products. It does this in areas where emissions are particularly difficult to avoid. The start-up wants to show that climate protection and value creation can go hand in hand. For us in Switzerland, this means: less CO₂ in the air and cheaper domestic energy from locally produced hydrogen.
