Platinum and other platinum group metals are set to play a pivotal role in the decarbonization of hydrogen production through their use in electrolyzers, catalyzing the production of hydrogen and oxygen using renewable energy – an emissions-free process.

Highlighting green hydrogen’s potential, the immediately addressable existing hydrogen market totals 95 million tons per annum, which primarily relies on fossil fuels for its production.

Recent research from the WPIC indicates that global electrolyzer capacity will grow significantly to reach a cumulative 212 gigawatts by 2030 from just six gigawatts in 2023. Correspondingly, based on the assumption that platinum-based proton exchange membrane (PEM) electrolyzers will have a 38% share of the electrolyzer market in 2030, annual platinum demand from PEM electrolyzers is forecast to increase from the 4,000 Troy ounces achieved in 2023 to 229,000 ounces in 2030.

Recent developments in North America highlight gathering momentum in the electrolyzer market. The US has made ambitious hydrogen subsidies available through the Inflation Reduction Act, with plans being developed for ten major hydrogen hubs.

In March, the US Department of Energy (DOE) awarded US$750 million to 52 clean hydrogen projects across 24 states to “dramatically reduce the cost of clean hydrogen and reinforce America’s global leadership in the growing clean hydrogen industry.”

Among other aims, the projects are expected to enable US manufacturing capacity to produce ten gigawatts of electrolyzers per year, enough to add annual production of 1.3 million tons of clean hydrogen per year. Canada is also making an investment tax credit available for clean hydrogen production.

Norwegian PEM electrolyzer maker Hystar – which is currently building a four-gigawatt, fully-automated electrolyzer factory in its home country – has revealed plans to expand into the North American market, establishing a multi-gigawatt factory there by 2027.

Hystar believes that the incentives on offer in the North American market ‘have created a highly favorable environment that demonstrates a clear commitment to providing our industry with much-needed certainty and financial support’.

Meanwhile, another Norwegian electrolyzer business, Nel, has received funding in the form of cash incentives and grants from both the US Department of Energy and the state of Michigan with a combined total of US$125 million in support of its plans to build a four-gigawatt electrolyzer plant in Michigan. In the planned new facility, Nel will manufacture its next-generation PEM electrolyzer technologies among other products.

In May, US PEM electrolyzer manufacturer Plug Power received a conditional commitment for an up to US$1.66 billion loan guarantee from the US DOE to finance the development, construction, and ownership of up to six green hydrogen production facilities.

With plans to operate a green hydrogen ‘highway’ across North America and Europe, Plug has built a state-of-the-art gigafactory to produce electrolyzers and fuel cells. It is developing multiple green hydrogen production plants targeting commercial operation by year-end 2028, which will use its own PEM electrolyzers.
