By reducing the amount of platinum and iridium used in water electrolysis devices, scientists believe they could bridge one of the largest barriers to green hydrogen production.
Hydrogen is a versatile, storable, potentially zero-carbon fuel source, that has been hailed as one of the solutions that will enable countries to reach their net-zero targets. It produces just heat and water as by-products when burned or used in fuel cells, making it a highly attractive alternative to fossil fuels in industry, power, shipping and transport.
However, due to the high production cost of water electrolysis devices required to produce it, green hydrogen has been considered too expensive to be worthwhile investing in.
A research team at the Korea Institute of Science and Technology (KIST) could have found the solution to this issue.
The researchers announced that they have developed a technology that can significantly reduce the amount of platinum and iridium, precious...
