CODAH (CO₂-driven alkane dehydrogenation) is SolidSky’s first deployment platform and the initial wedge of our agentic lab approach. It enables low-temperature alkane dehydrogenation using CO₂ as a co-reactant, facilitating selective C–H activation while suppressing coking and unwanted C–C cleavage.

Operating at sub-650°C temperatures, CODAH achieves approximately 70% conversion and 99.9% selectivity with no observed deactivation . By integrating as a slipstream retrofit into existing crackers, the system leverages facility CO₂ streams and alkane feeds while maintaining compatibility with established offtakes.

The economic impact is material. For ethane crackers in the 1–1.5 Mt/year range, CODAH can deliver €75–400M per year in margin uplift through reduced furnace duty, improved light-ends conversion, and CO co-product value. Similar uplift is available in refineries via off-gas valorization . Payback periods can fall below one year without reliance on carbon credits.

CODAH is not positioned as a green premium technology. We are a margin restoration mechanism that simultaneously reduces net CO₂ emissions.
