Lower cost electrochem process to produce C2+ products
Summary
This technology produces catalysts derived from Prussian Blue Analogues (PBAs) — a class of low-cost, tunable metal-organic materials — for the electrochemical reduction of CO₂ into valuable multi-carbon (C2+) products such as ethylene. The PBA-derived catalyst design enables operation under industrially relevant conditions, making it more amenable to scale-up than many lab-optimised electrocatalysts.
Current catalyst stability tested over 145 hours. Planning to extend operating stability to 1000 hours at an even higher ethylene production rate. Planning to scale to 100 cm2 and then operate at stack level and high pressure for practical deployment.
What makes this novel compared to the current best-in-class technology?
PBA-derived catalysts offer a low-cost, compositionally tuneable alternative to conventional copper-based electrocatalysts for CO₂ reduction. Their structured metal coordination environment can be engineered to favour C–C coupling, improving multicarbon selectivity under industrially relevant operating conditions where most competing catalysts underperform.
