Sustainable Chemistry/Waste Valorization Green Energy/Hydrogen Production

A research team published findings in Joule detailing a high-efficiency electrochemical system that uses glycerol, a byproduct of biodiesel, to produce hydrogen and valuable chemicals like formate. This new anion exchange membrane water electrolysis (AEMWE) system improves upon conventional methods by replacing the energy-intensive oxygen evolution reaction (OER) at the anode. The technology is presented as a scalable, carbon-neutral platform for industrial resource utilization.

“To address these challenges, the research team, led by Juchan Yang, principal researcher at Korea Institute of Materials Science (KIMS), in collaboration with Professor Ji-Wook Jang, Hankwon Lim, and Hosik Lee of Ulsan National Institute of Science and Technology (UNIST), developed an anion exchange membrane water electrolysis (AEMWE) system that utilizes glycerol as an alternative feedstock and applies the glycerol oxidation reaction (GOR) at the anode as a paired electrolysis strategy.”
SINGLE SOURCE
Only one web search result explicitly mentions the development of an electrochemical system using glycerol and notes the involvement of a research team, though it does not name Juchan Yang, KIMS, or the specific collaborators from UNIST. The other web results are about unrelated topics (AI, HKUST).

“The team also employed a copper–cobalt-based non-precious metal catalyst, achieving high catalytic activity and stability without relying on expensive noble metals.”
SINGLE SOURCE
The web search result mentioning the research on waste biomass implies the use of advanced catalysts, but none of the gathered evidence explicitly confirms the use of a 'copper–cobalt-based non-precious metal catalyst' achieving high activity and stability. This detail appears specific to the original source material not fully captured in the search snippets.
