Hydrogen breakthrough: New liquid stores clean fuel at room temperature

SMRTR summary

Scientists have developed a novel hydrogen-rich liquid that remains stable at room temperature, addressing a major challenge in using hydrogen as a clean fuel. The liquid, created by mixing ammonia borane and tetrabutylammonium borohydride, contains up to 6.9% hydrogen by weight and releases pure hydrogen gas when heated to 60°C. This breakthrough could make hydrogen storage and use more practical for real-world applications in clean energy and transportation.
