On today’s show Japan’s innovative approach to their hydrogen strategy, the race for white hydrogen and India’s shift toward pink hydrogen. I’ll focus on technical breakthroughs, economic potential, and research priorities, with emissions impacts looking at nuclear versus renewable energy projects. All of this on todays hydrogen podcast.

Our first story comes from The Print, published on May 3 exploring what Japan’s evolving hydrogen strategy teaches us. Unlike many nations reserving hydrogen for hard-to-abate sectors like steel or shipping, Japan is pushing its use across power generation, gas blending, passenger vehicles, and even heating, aiming to lead the global hydrogen economy. Let’s dive into the details of this multifaceted approach.

Technically, Japan’s strategy is built on a mix of domestic production and imports, adapting to its limited renewable resources. The Japan Atomic Energy Agency (JAEA) is pioneering clean hydrogen production using its High Temperature Engineering Test Reactor (HTTR). By 2028, JAEA plans to produce hydrogen via thermochemical water splitting at 900°C, leveraging the reactor’s high heat to achieve 50% efficiency—surpassing the 40% efficiency of standard electrolysis, which typically requires 50 kWh/kg of hydrogen. A 100 MW HTTR could produce 2,000 tons of hydrogen annually, enough to power 500 Toyota Mirai sedans for a year, each with a 402-mile range on a 5 kg tank at 700 bar. This nuclear-driven process reduces electricity demand compared to electrolysis, making it ideal for a grid with limited renewable capacity—Japan’s solar and wind output averages 20-25% capacity factor, per industry data.

For power generation, Japan is blending hydrogen into natural gas pipelines, targeting 20% hydrogen by volume by 2030. This requires retrofitting 10,000 km of pipelines with hydrogen-compatible materials like polyethylene, ensuring safe transport at pressures up to 10 bar. A 1,000 MW gas turbine, blending 20% hydrogen, consumes 10,000 tons of hydrogen/year, reducing reliance on imported LNG, which makes up 30% of Japan’s energy mix. In mobility, the Toyota Mirai and upcoming hydrogen trucks use fuel cells with 60% efficiency, consuming 1 kg per 50 miles. Japan’s also piloting hydrogen in heating, with Kawasaki Heavy Industries developing burners that mix hydrogen with natural gas for residential use, aiming for 5% blending by 2027—potentially serving 1 million homes with 50,000 tons of hydrogen annually.

On the import side, Japan sources 200,000 tons of hydrogen yearly from Australia, produced via brown coal gasification with carbon capture—a pragmatic move, though not fully green. Liquefied hydrogen is shipped at -253°C in specialized carriers, with a single ship carrying 10,000 tons costing $500 million to build, per industry estimates. Japan’s Suiso Frontier, the world’s first liquefied hydrogen carrier, has completed multiple trips, proving the tech’s viability. Domestically, Japan aims to scale production to 3 million tons/year by 2040, combining nuclear, electrolysis, and imports, positioning itself as a hydrogen hub for Asia.

Economically, this is a massive undertaking. Building a single hydrogen import terminal costs $100-$200 million, so scaling to 10 terminals for 3 million tons could cost $1-$2 billion. Retrofitting 10,000 km of pipelines for blending adds another $1-$2 billion, while upgrading nuclear reactors like the HTTR for hydrogen production costs $500-$700 million per 100 MW facility. At $4-$5/kg, 3 million tons/year generates $12-$15 billion in revenue, creating 15,000-20,000 jobs in infrastructure, manufacturing, and shipping. However, Japan’s 80% import dependency—160,000 of 200,000 tons in 2025—poses risks, as global supply chains could disrupt costs, and brown coal hydrogen’s carbon capture isn’t 100% effective, raising questions about long-term sustainability. The narrative of ‘Japan leading hydrogen’ is compelling, but its reliance on imports and high upfront costs highlight the need for global collaboration, a theme we’ll see in the white hydrogen race next.

Our second story comes from Yahoo News, published today, May 3, 2025, titled ‘Global Race for White Hydrogen.’ This article dives into the emerging excitement around white hydrogen—naturally occurring hydrogen trapped underground—described as a potential ‘white gold rush’ that could revolutionize the energy sector. 

The technology behind white hydrogen is rooted in its geological origins. The article highlights that this hydrogen is formed naturally deep within the Earth, with companies now racing to tap into these hidden reserves. A key example is a discovery in Mali, where a well drilled in 1987 unexpectedly produced gas that was 97% hydrogen, a find that powered a village’s electricity needs for over three decades. This natural occurrence has sparked interest, with the article noting that white hydrogen could be a game-changer due to its potential abundance. The process involves drilling to access these underground deposits, a method likened to oil and gas extraction, though specific techniques are still being developed. The article doesn’t provide exact production figures but emphasizes the scalability potential, with companies betting on this resource to meet future energy demands.

The race is intensifying globally. The article mentions that mining giants and oil majors are joining the fray, driven by the promise of a carbon-free energy source. A standout player is Koloma, a U.S.-based startup that has attracted significant attention, raising over $300 million, including funding from Bill Gates’ Breakthrough Energy. This investment underscores the high stakes, with Koloma focusing its efforts on drilling in the United States, particularly in regions believed to hold substantial white hydrogen reserves. The article also points out that 40 companies were actively searching for these deposits in 2023, up from just 10 in 2020, reflecting a rapid escalation in interest. However, it cautions that progress has been slow, with no major breakthroughs reported in the past 12 months, suggesting that the technology and extraction methods are still in early stages.

Economically, the potential is significant but uncertain. The article suggests that white hydrogen could be produced at a lower cost than other forms of hydrogen, positioning it as a competitive energy source. While specific cost figures aren’t provided, the implication is that its natural occurrence could reduce production expenses compared to manufactured hydrogen like green or blue variants. If scaled to 1 million tons per year—a hypothetical target based on the article’s emphasis on abundance—this could generate substantial revenue, potentially in the billions, though exact estimates are speculative without further data. The creation of jobs is another economic highlight, with the article indicating that the exploration and development could lead to thousands of new positions in drilling, infrastructure, and related industries. However, the lack of progress over the past year hints at challenges, including the need for significant investment in unproven technology, which could increase costs and delay commercialization. The narrative of a ‘white gold rush’ is enticing, but the article’s note on stalled progress suggests a need for patience and innovation to turn this promise into reality, setting the stage for India’s strategic pivot in our next segment.

Our third story, from Moneycontrol on May 2, 2025, dives deep into India’s pivot to pink hydrogen as its green hydrogen mission struggles. Let’s unpack this, focusing on the use of nuclear-powered electrolyzers—a more reliable energy source than renewables, as you’ve noted—and compare the particulate emissions from developing nuclear plants versus solar or wind farms.

Pink hydrogen, produced via electrolysis using nuclear power, is emerging as a viable option for India’s net-zero goal by 2070. The National Green Hydrogen Mission aims for 5 million tons/year by 2030 but is faltering—off-take agreements are lagging, with only 412,000 tons of derivatives committed to Japan and Singapore, per Minister Pralhad Joshi. Green hydrogen, reliant on solar and wind, faces challenges: inconsistent energy supply (solar peaks at 3-4 cents/kWh but drops at night, wind varies regionally), and site constraints near refineries requiring large land footprints. Nuclear power offers a solution—its 90% capacity factor versus 25-30% for renewables ensures steady 24/7 power at 2-3 cents/kWh, per industry data.

Technically, nuclear-powered electrolyzers are a game-changer. A 1 GW nuclear plant, like those planned with private sector entry, can power 200 MW of PEM electrolyzers, producing 40,000 tons of hydrogen/year at 50 kWh/kg—enough for 10,000 trucks driving 500 miles daily. Excess nuclear capacity, often underutilized at 60-70% load, can be tapped, with plants like Kudankulam ideal for colocating electrolyzers, avoiding the land and grid issues of renewables. India’s 7.5 GW nuclear fleet could scale to 20 GW by 2030, per government plans, yielding 1.6 million tons/year—surpassing green targets. Oil PSUs like Reliance are exploring this, leveraging nuclear’s stability for industrial applications like ammonia production.

Let’s compare particulate emissions from developing a nuclear plant versus a solar or wind farm, focusing on PM2.5—fine particles linked to air quality issues. Building a 1 GW nuclear plant involves concrete production, heavy machinery, and transport, emitting about 50,000 tons of PM2.5 over a 5-10 year construction period, per lifecycle analyses (EPA, DOE data). A 1 GW solar farm, requiring 5,000 acres, involves land clearing, panel manufacturing, and installation, emitting 30,000 tons of PM2.5—40% less than nuclear, due to less concrete and shorter timelines (2-3 years). A 1 GW wind farm, spread over 10,000 acres, emits even less—20,000 tons of PM2.5—because turbines use fewer materials, though land disturbance can stir dust. However, nuclear’s operational phase is cleaner: zero PM2.5, NOx, or SOx, versus solar and wind’s indirect emissions from maintenance (500-1,000 tons PM2.5/year for 1 GW). Over 30 years, nuclear’s total PM2.5 footprint is 50,000 tons, while solar and wind reach 45,000 and 35,000 tons, respectively, narrowing the gap. Nuclear’s steady output makes it a better fit for pink hydrogen, despite higher construction emissions.

Economically, pink hydrogen is promising. At $4-$5/kg, 1.6 million tons/year generates $6.4-$8 billion in revenue, creating 8,000-12,000 jobs. Nuclear electrolyzer plants cost $300-$400 million per 200 MW, but leveraging excess capacity saves $60-$120 million—20-30% less than green hydrogen’s $7-$8 billion for 5 million tons. Nuclear’s reliability could outpace renewables, though safety and private sector hesitancy remain challenges.
