Researchers at Tohoku University in Japan have made a significant breakthrough in the field of green hydrogen production. They have developed a cobalt-phosphide catalyst that demonstrates a remarkable capability to reduce the cost associated with producing green hydrogen. This new catalyst has shown performance levels comparable to platinum, a precious metal commonly used in hydrogen production, but at a much lower cost. The catalyst's stability was also tested over 300 hours of continuous operation, indicating its reliability for long-term use. The projected cost of hydrogen production using this catalyst is estimated to be around $2.17 per kilogram, inching close to the $2.00/kg target set by the U.S. Department of Energy for cost-competitive green hydrogen. This achievement is a significant step towards overcoming a major obstacle in scaling up hydrogen fuel production as a clean energy source. The reduced cost of green hydrogen could lead to its faster adoption in various industries such as steelmaking, trucking, and chemical manufacturing, where hydrogen is used as a feedstock or fuel. Companies that invest in electrolyzers and hydrogen infrastructure now stand to benefit from the early adoption of these more affordable and efficient catalysts, positioning themselves as key players in the green hydrogen economy.
