University of Manchester team develops cheaper catalyst to turn captured CO2 into ethanol

Researchers at the University of Manchester have published a study in Catalysis Science & Technology showing a new homogeneous catalytic process that converts methanol, carbon dioxide, and hydrogen into ethanol using inexpensive and stable catalyst precursors. The work addresses a key bottleneck in carbon capture utilization: making the conversion step cost effective enough to compete with fossil derived ethanol. The catalyst uses ruthenium and cobalt, both relatively abundant metals, and operates under industrially relevant conditions. If the process scales, it could give captured CO2 a market pathway into chemicals and fuels. The paper is behind a paywall so the exact yields and energy balance are not visible from the press release alone. That matters because many CO2 to ethanol routes have struggled with selectivity and energy input. This one claims cheaper precursors, but the full efficiency data will determine whether it is a real step forward or just another lab result.
