In a Zoom video interview with Creamer Media’s Engineering News & Mining Weekly, Plug Power president and CEO Andy Marsh has pointed out that platinum-based proton exchange membrane (PEM) technology is at the heart of everything that this Nasdaq-listed company does.

Plug is a prime mover in the US’s platinum- catalysed green hydrogen and fuel cell economy and the adoption by US business of this planet-friendly way of doing things is because it pays them to do so.

The company built and operates the US’s largest liquid green hydrogen plant, a 15-t-a-day liquid hydrogen plant that uses 40 MW of Plug’s platinum- and iridium-catalysed electrolysers.

More than 80 000 forklift trucks are powered by the 250 hydrogen fuelling stations it has built.

Between Walmart and Amazon, there are about 150 sites that use Plug’s PEM technology to operate around the clock.

With the help of Plug’s technology, these companies talk about moving 8% to 10% more pallets an hour, while also being users of clean energy.

“Where you need fast start-up, where you need to be able to work in cold environments, where you can really change the power level instantaneously, PEM is the answer,” Marsh highlighted.

Plug has a $1.66-billion loan contract with the US Department of Energy (DoE) to build a huge hydrogen plant in Texas. The DoE has been actively involved in research and development of green hydrogen and fuel cell technologies, recognising their potential to decarbonise various sectors and contribute to a cleaner energy future.

The DoE’s hydrogen and fuel cell technologies office has been focused on developing technologies that can produce hydrogen at $2/kg by 2026 and $1/kg by 2031 via net-zero- carbon pathways, in support of the Hydrogen Energy Earthshot goal of reducing the cost of hydrogen by 80% to $1/kg in one decade.

This has been under way against the backdrop of the Inflation Reduction Act (IRA), which was introduced to save the universe from the potentially catastrophic consequences of climate change.

Stimulated has been heavy investment in clean energy, climate action, and environmental justice, with the aim of reducing greenhouse-gas emissions and transitioning to an environmentally protective economy.

The IRA legislation that former President Joe Biden signed into law in August 2022 has the capacity to enable $3-trillion in climate investments in the 2022–2032 period and $11-trillion in overall infrastructure investments by 2050.

Key ingredients to the success of all this are platinum group metals, which South Africa hosts in greatest abundance.

Although platinum group metals are not subject to the latest US tariff impositions, reverberations of the US April 2 ‘Liberation Day’ announcement are being felt, given the 30% tariff regime imposed on South Africa, amid the 10% base tariff, as well as alongside higher individual tariffs for specific countries, including 20% for the EU, 24% for Japan, 26% for India, and 34% for China.

“I’ve spent some time with the DoE. I’ve spent some time with many Republican Congress folks. Now, there’s certainly no guarantee that many of the incentives that were put in place to grow the green hydrogen industry will continue, but I think it’s likely they will.

“There’s over 20 members of the House who are Republicans who asked the President and asked the Speaker not to change the provisions of the IRA when it comes to hydrogen.

“It’s an industry that’s strongly supported by the oil and gas industry. There are some big projects, especially in places like Texas, including our own 45 t liquid plant, that are still on the drawing board.

“There will be hydrogen hubs in the United States. It probably isn’t happening as fast as people hoped three or four years ago, but we really do believe it’s going to continue,” said Marsh.

Augmenting its US growth is the outstanding green hydrogen and fuel cell acclaim that this early-moving green company has generated since being established in 1997.

Plug has won considerable recognition in Europe and Australia, and is encouraging Africa to build out its energy grid network using lower-cost solar and wind and including green hydrogen and fuel cell development. In this way, a percentage of minerals that Africa hosts in such abundance can be used by Africa and in Africa through the development of industries that create sustainable employment in the new planet-friendly electrification world for the people of Africa.

Interestingly, there are times in the day when the renewable energy comes free of charge and can, during those low-use periods, be used to generate green hydrogen for use during periods of peak electricity demand.

Engineering News & Mining Weekly: As South Africans, we love PEM, because it signals that there’s been use of platinum group metals, which we host in great abundance. Give us more insight into Plug’s use of PEM.

PEM is the heart of what we do for both fuel cells and electrolysers. We move about 35% of the retail food in the United States, and we use exclusively PEM technology, and platinum’s a big part of my life. I think we’ve also done more deployments of PEM electrolysers in the Western world than anyone else, and they use platinum as well as iridium. We are a pure PEM house, and when you think about applications where you need fast start-up, where you need to be able to work in cold environments, where you can really change the power level instantaneously, PEM is really the answer. There’s always a lot of debate about how much platinum, how much iridium, we’re going to use. Believe it or not, there’ll come a day where it won’t be fossil fuels anymore, and the world will be using iridium and platinum in fuel cells and electrolysers.

Well, there’s great alignment between us, then?

Yes, there is, we need your metals.

How many functioning operations has Plug Power enabled – and how many projects does it have on the go in the US?

There are about 250 hydrogen fuelling stations in the US that were built by Plug that power over 80 000 forklift trucks. Between Walmart and Amazon, there are probably 150 sites that use Plug’s PEM technology to operate 24/7. And why do they do it? They like being sustainable, but what they’re really doing it for is that they can move goods faster. With Plug’s technology, these companies talk about moving 8% to 10% more pallets per hour, which really makes their operation more efficient. We also take power off the grid and that’s important today, because big sellers are things like refrigerated foods, and that power can help them expand refrigerant capacity. So, there is a true value proposition, which is what we really need in this industry to make a difference, and it goes beyond sustainability. It goes to the heart. We help you save money, and that’s what we offer at Plug, and that’s why our customers are using our products. We also have lots of PEM electrolysers out there.

What contribution is Plug Power making to the growth of the green hydrogen and fuel cell economy in Europe?

We have big deployments, especially in our electrolyser business, in Europe. For example, we’re doing a 100 MW electrolyser site with Galp, which is the largest refiner in Portugal. We’re doing a big deal in Spain with Iberdrola. We probably have deployed more PEM electrolysers than anyone else in Europe, and it’s a real interesting market. If you take a step back, some of these markets for fuel cells and hydrogen have been really difficult. But when you start thinking about where people are moving to green hydrogen, they’re actually moving to applications in which they can substitute. Galp uses a lot of grey hydrogen in refining. Now they’re going to be mixing in green hydrogen, and that really helps them reduce their taxes, because of the tax on carbon in Europe, so there’s a real market and opportunity to help these companies in the oil and gas industry to save a lot of money, and all they really have to do is replace natural gas reformers with electrolysers. It’s a pretty simple value proposition when you compare it to if you’re doing on-road trucking, where you have to change the supply chain for trucking. You have to think about service. You have to think about financing. You have to think about where fuelling stations are. That’s where the market is today . . . substitution for ammonia, and I think everybody in the world has figured out that green ammonia is really important in the fertilising industry. Also, in places like Australia, where they’re looking to ship green ammonia into Japan and South Korea to burn that ammonia to help them meet their carbon footprint. I really like these activities that we have going on the electrolyser business. We’re actually working on eight gigawatts (8 GW) worth.That’s a lot of ammonia, a lot of methanol, but these opportunities are not something that’s futuristic. These opportunities are going to be happening.

What contribution is Plug Power making to the growth of the green hydrogen and fuel cell economy in Australia?

Australia makes its living shipping minerals from Australia into the rest of Asia, into the world, and Australians are trying to figure out how they can ship the sun and wind to the rest of the world, and the best way for them to ship the sun and wind is to make hydrogen or to make green ammonia and green methanol. We have some really exciting projects going on. One is a project that’s looking to do over two gigawatts (2 GW) of electrolysers to produce green ammonia, to put it really into the value chain for ammonia today. The government wants to continue to be an exporter and the best thing they got to export is the sun, and the best way to export the sun to Korea and Japan is to make green ammonia or green methanol or green hydrogen, and Plug’s right in the middle of all that.

How are you viewing the African market? You haven’t really participated in the African market to any great extent, or have you?

We have, a little, and I think it’s a great opportunity, especially where you are in South Africa. We actually built a big fuelling station in South Africa for Anglo American at one time as they looked at deploying fuel cells into the mining industry. The key issue with Africa is to understand how these projects can be financed. We probably have two or three projects going on in Africa, but one of the key elements is the willingness of financiers to back these projects, and, especially when it comes to electrolyser business, we really follow those projects. But governments can help, too. It’s a real interesting industry, and a place like South Africa really should think about it. One of the things we’re most proud of is that we have probably 1 500 blue collar workers of Plug Power who are getting hands-on experience with new technologies, working on fuel cells and electrolysers, adding to their capabilities list. I would love to find a way to do more deals in Africa.
