Toshiba – New large-scale production technology for electrolysis electrodes for hydrogen production from renewables cuts iridium use to 1/10.
Toshiba Corporation (TOKYO: 6502) has developed large-scale production technology for the electrodes that realizes high level efficiency in Power to Gas (P2G) technology, essential know-how for advancing toward a carbon neutral society, while reducing the use of iridium, one of the world’s rarest precious metals, to 1/101.
P2G uses electrolysis of water to convert renewable energy into hydrogen, for storage and transportation to where it is needed. Polymer Electrolyte Membrane (PEM) electrolysis is seen as a highly promising conversion method, as it is reacts rapidly to power fluctuations and is highly durable. However, PEM uses iridium, one of the rarest of all traded precious metals, as the catalyst in its…
