Story summary

Researchers in South Korea developed a 20-kW solid oxide electrolysis cell (SOEC) that operated for 3,000 hours at 83% efficiency.
The system uses waste heat from industrial sources to cut electricity use by 15% and hydrogen costs by 25%.
In Japan, scientists created a transparent tungsten trioxide film for solar-driven water splitting with 93% oxygen evolution.
Both innovations aim to advance clean hydrogen production and influence the global energy landscape.
