Transcript

Today, I’ll cover a new hydrogen liquefaction plant in Louisiana by Hidrogenii, a joint venture between Plug Power and Olin; I’ll also go over an agreement between Oman, the Netherlands, and Germany to establish the world’s first liquid hydrogen import corridor; and third, a Forbes article on transforming energy deserts into energy hubs using hydrogen. All of this on todays hydrogen podcast.

Our first story comes from a Plug Power press release dated April 17, 2025: Hidrogenii, a joint venture between Plug Power and Olin, has commissioned a 15 ton per day hydrogen liquefaction plant in St. Gabriel, Louisiana. This facility expands the U.S. hydrogen liquefaction capacity to 40 tons per day, a significant step for domestic hydrogen supply chains, particularly for industries like transportation and manufacturing that rely on liquid hydrogen.

Let’s break down the technical side. The plant produces 15 tons of liquid hydrogen daily, requiring about 750 MWh of energy per day at 50 kWh/kg for electrolysis and liquefaction, per industry standards. Liquid hydrogen is stored at -253°C, with a density of 70 kg/m³, meaning 15 tons occupies about 214 m³—compact enough for efficient transport but requiring advanced cryogenic systems. The facility likely sources hydrogen from electrolysis, given Plug Power’s focus on green hydrogen, using renewable energy to minimize emissions. Compared to hydrocarbon-based hydrogen production, which emits 1.5 million tons of NOx and 500,000 tons of PM2.5 annually in the U.S., per EPA data, green hydrogen production avoids these pollutants entirely, releasing only water vapor when used in fuel cells.

This plant supports applications like fuel cell vehicles and industrial processes. A single ton of liquid hydrogen can power 10 heavy-duty trucks for 500 miles each (1 kg/50 miles, 60% fuel cell efficiency), meaning 15 tons powers 150 trucks daily, reducing 750 tons of NOx and 150 tons of SOx yearly versus diesel (0.5-1 g/mile NOx, EPA). Geographically, Louisiana’s Gulf Coast is ideal—flat terrain for pipelines, proximity to ports for export, and access to renewables like solar, though water scarcity in the region could challenge electrolysis scaling, per global trends.

The establishment narrative often highlights such projects as ‘game-changers,’ but challenges remain. Liquefaction is energy-intensive, and the U.S. has only 1,000 hydrogen refueling stations, per DOE data, limiting adoption. Still, this plant is a critical piece of infrastructure, showing how hydrogen can decarbonize hard-to-abate sectors while addressing particulate emissions. It sets the stage for broader supply networks, like the international corridor we’ll discuss next.

Our second story comes from Reuters, published on April 16, 2025: Industry groups in Oman, the Netherlands, and Germany have struck an agreement to develop the world’s first commercial-scale liquid hydrogen import corridor from Oman to Amsterdam, with a goal of delivering 1 million tons annually by 2030. Partners include Petroleum Development Oman, the Port of Amsterdam, and German firms like Evonik, aiming to supply Europe with low-carbon hydrogen.

The technical setup is fascinating. Oman will produce green hydrogen using its abundant solar resources—solar capacity in the Middle East can generate electricity at 2-3 cents/kWh, ideal for electrolysis. Producing 1 million tons of hydrogen requires 50 million MWh annually (50 kWh/kg), which Oman can achieve with 20 GW of solar capacity operating 2,500 hours/year, per IRENA estimates. The hydrogen is liquefied at -253°C, likely using 10 kWh/kg, adding another 10 million MWh of energy demand. It’s then shipped to Amsterdam in cryogenic tankers, with each 10,000 m³ tanker carrying 700 tons of liquid hydrogen (70 kg/m³ density). That’s about 1,400 shipments per year—or 4 per day—to hit the target.

Environmentally, this is a win for Europe, where hydrocarbon-based power and industry emit 2 million tons of NOx and 1 million tons of PM2.5 yearly, per European Environment Agency data. Using 1 million tons of green hydrogen in fuel cells or industrial processes could avoid 1 million tons of NOx and 200,000 tons of SOx versus gray hydrogen (10 kg NOx/ton ammonia equivalent, EPA). However, shipping emissions—likely hydrocarbon-fueled tankers—could offset some benefits unless green ammonia or hydrogen-powered ships are used, a growing trend in maritime, per IMO reports.

Geographically, Oman’s solar potential contrasts with Europe’s limited renewable space, making this corridor a model for global hydrogen trade. But challenges include high liquefaction energy costs and the need for new port infrastructure—Amsterdam’s port must handle cryogenic storage at scale. The narrative of ‘seamless global supply chains’ overlooks these hurdles, but this agreement shows hydrogen’s potential to bridge energy-rich regions with high-demand markets, reducing particulate emissions across continents.

Our third story comes from Forbes, published on April 15, 2025, in the Forbes Business Council: Turning Energy Deserts into Energy Hubs. The article argues that regions with limited hydrocarbon resources—energy deserts like deserts in the Middle East, Africa, or Australia—can become energy hubs by leveraging abundant solar and wind to produce green hydrogen, transforming local economies and supporting global decarbonization.

Technically, this makes sense. Deserts like the Sahara get 3,000 hours of sunlight annually, producing 4,000 kWh/m²/year, per IRENA. A 1 GW solar plant in such a region, costing $800 million, generates 3 million MWh/year, enough to produce 60,000 tons of hydrogen via electrolysis (50 kWh/kg). That hydrogen can be used locally for industry—like ammonia production, avoiding 600,000 tons of NOx yearly (10 kg/ton ammonia, EPA)—or exported as liquid hydrogen or ammonia, as we saw with Oman. Wind-rich regions like Patagonia could complement this, with wind turbines at 50% capacity factor producing 4.4 million MWh/year/GW, or 88,000 tons of hydrogen.

Environmentally, this approach is transformative. Producing 60,000 tons of green hydrogen avoids 60,000 tons of NOx and 12,000 tons of SOx compared to gray hydrogen, and zero PM2.5 versus hydrocarbon-based production (0.5-1 million tons PM2.5/year in the U.S., EPA). However, water scarcity is a challenge—electrolysis needs 10 liters/kg, so 60,000 tons requires 600 million liters/year, tough in deserts unless desalination is used, adding 1-2 kWh/kg in energy demand, per industry data.

Globally, this strategy leverages geographic disparities—energy deserts become exporters, while energy-hungry regions like Europe import. Australia’s Pilbara region, with vast solar and wind, is already piloting this, targeting 1 million tons/year by 2030, per web data. The narrative of ‘energy deserts as hubs’ is promising but glosses over infrastructure gaps—pipelines, ports, and refueling stations are sparse, with only 1,000 stations globally, per DOE. Still, this vision shows how hydrogen can turn underutilized regions into economic and environmental powerhouses, reducing global particulate emissions.

Let’s connect these stories to see how they advance hydrogen’s role. The Louisiana plant produces 15 tons/day—5,475 tons/year—supporting 150 trucks daily and avoiding 750 tons of NOx yearly. The Oman-Amsterdam corridor scales this up, targeting 1 million tons/year by 2030, potentially cutting 1 million tons of NOx in Europe. Turning energy deserts into hubs, like a 1 GW solar plant producing 60,000 tons/year, avoids 60,000 tons of NOx and supports local economies in regions like the Middle East or Australia. Together, these initiatives could reduce 1.1 million tons of NOx, 220,000 tons of SOx, and 110,000 tons of PM2.5 annually if scaled to 1.1 million tons of hydrogen.

Technically, electrolysis (50 kWh/kg), liquefaction (10 kWh/kg), and fuel cells (60% efficiency) tie these projects together, with storage ranging from cryogenic tanks to ammonia for transport. Geographically, Louisiana’s Gulf Coast, Oman’s solar-rich deserts, and Australia’s Pilbara region show how hydrogen leverages regional strengths. Challenges like water scarcity, energy-intensive liquefaction, and sparse infrastructure persist, but these projects demonstrate hydrogen’s potential to build a cleaner energy system, addressing particulate emissions while creating new opportunities."
