2023 R&D 100 Award: Cost-Effective and Clean Hydrogen Production With Molten Catalysis -  August 23rd 2023

Hydrogen as a new fuel is critical to decarbonizing our economy and reducing our environmental impact. However, many processes that produce hydrogen also produce carbon dioxide (CO2), a known greenhouse gas. A team of Berkeley Lab researchers has improved a process called methane pyrolysis to produce hydrogen and carbon without CO2 emissions. The researchers developed a ternary-liquid-metal-catalyst for methane pyrolysis. Their new “multi-catalyst” could simultaneously perform with high efficiency, selectivity, and durability for methane pyrolysis at mild temperatures (450-800 oC). Most importantly, this new catalyst can be easily fabricated using non-precious metal elements, making it both scalable and cost-effective for industrial use. The technology was filed for US patent application (Homogeneous Ternary Liquid Metal System for Clean Hydrogen Production – Intellectual Property Office) and the core science understanding was accepted in journal Science.
