C+UP .
Presenting Company
C+UP converts captured CO₂ and renewable electricity into clean, high-purity propane—a carbon-negative fuel that’s drop-in ready for today’s infrastructure. Our patented electrochemical process operates without hydrogen, heat, or pressure, making it simpler and more scalable than existing synthetic fuel or bio-propane pathways. We’re targeting ethanol producers as our beachhead market, enabling them to monetize biogenic CO₂ emissions through on-site fuel use or local sales. With support from DOE ARPA-E, NSF, and Illinois Tech, C+UP is building the first modular platform for turning industrial CO₂ into low-cost, high-value fuels and feedstocks.
