A group of scientists in Singapore have developed an optimization process for the production of low-cost Spinel Oxide catalysts, which could be key to pulling down the cost of green hydrogen through electrolysis. The team, led by those at Nanyang Technological University (NTU Singapore) has claimed that the discovery “breaks a bottleneck” in electrolysis, which will remove the fog around how exactly spinel oxides work and allow them to be pushed into commercial operation. In the production of green hydrogen from electrolysis, two reactions take place: one to produce hydrogen and one to produce oxygen, while the gases are kept separate by a membrane. But it’s actually the oxygen production that is the bottleneck in the speed of the process,…
