• Producing clean hydrogen from water is often compared to storing renewable energy in chemical form, but improving the efficiency of that process remains a scientific challenge. • Researchers at Tohoku University have now developed a catalyst design that helps hydrogen form more smoothly under alkaline conditions, a key step toward practical green hydrogen production.
Article Summaries:
- Researchers at Tohoku University have introduced a new catalyst design that improves the efficiency of alkaline anion‑exchange membrane (AEM) electrolyzers, a technology used to produce green hydrogen from water. The catalyst promotes smoother hydrogen evolution, reducing energy losses during the electrolysis process. By lowering the overpotential required for hydrogen formation, the design could make AEM electrolyzers more cost‑effective and scalable for renewable‑energy‑based hydrogen production. The development represents a significant step toward practical, low‑cost green hydrogen as a storage medium for intermittent renewable power.
