Divea
divea.ch develops graphene-based membrane filters that separate CO2 from industrial flue gas streams without heat or solvents, enabling cost-effective carbon capture for hard-to-abate sectors. The company's atom-thick membranes feature pores sized to match CO2 molecules, and its modular installations are compact enough for space-constrained sites like offshore platforms. The technology targets low-concentration emission streams, such as those from aluminum smelters, where traditional capture methods are economically unviable.

Problem
Industries such as cement, iron and steel, and chemicals account for roughly 34 percent of global CO2 emissions, and a significant portion of these emissions come from the production process itself rather than energy use. These process emissions are notoriously difficult and expensive to abate, especially in low-concentration streams where conventional carbon capture technologies are not economically viable.
Solution
divea.ch produces graphene-based membrane filters that separate CO2 from industrial flue gas with exceptional efficiency and minimal energy input. The membranes are synthesized at one-atom thickness, then perforated with pores sized precisely to match the CO2 molecule, allowing only CO2 to pass through while blocking other gases. These porous graphene membranes are rolled and integrated into modular installations that connect directly to an emitter's flue gas system, removing CO2 for permanent storage or conversion into derived products. The technology operates without heat or solvents, requiring only electrical energy, which broadens the range of industries that can adopt carbon capture. The company's record-breaking membrane performance makes carbon capture economically viable even for low-concentration streams, such as those from aluminum smelters.
Target Audience
Industrial emitters in hard-to-abate sectors including cement, iron and steel, chemicals, and aluminum smelting, as well as offshore oil platforms, that need cost-effective CO2 capture solutions for low-concentration flue gas streams.
