IRIDIUM’S CHALLENGE
IN THE AGE OF GREEN HYDROGEN
Negotiations on Japan’s FY2024 budget are underway, with the Ministry of Finance squaring off against METI, the MoE, and others. The need to invest big in clean energy is substantial. The amount of funds, and for which pathways, will determine where Japan sits mid-way through a decade during which it vowed to slash emissions by half. This budget will be the biggest yet and will struggle to satisfy all parties. Who are the likely winners?
JAPAN’S LONG ROAD
TO NUCLEAR WASTE DISPOSAL
The disposal of nuclear waste is a critical challenge for countries that rely heavily on nuclear energy. Japan, however, is struggling to convince municipalities to house the infrastructure for nuclear waste disposal. All hope rests with the two candidate spots in Hokkaido with more than a few challenges. Finding a way around the roadblocks, or another town to volunteer as a host, is now center stage in Japan’s nuclear industry.

JAEA nuclear fusion project generates super hot plasma, milestone for clean energy
(Nikkei Asia, Oct 25)
TAKEAWAY: In 2022, PM Kishida said nuclear fusion is part of his clean energy strategy, and he allowed startups in the field to claim state support. However, fusion energy projects remain highly experimental. At best, optimistic experts only expect it to be commercially viable by 2035. Meanwhile, more pessimistic experts doubt it will ever be commercially viable because, they say, the technological challenges are so great that the vast development and operational costs would make it unprofitable as a commercial energy source.
Japan, Danish PMs meet to promote floating offshore wind, establish global standards
(Nikkei, Oct 24)
TAKEAWAY: Floating offshore wind is still highly experimental and in its nascent stage. Globally, in 2020, its total installed capacity was a mere 17 MW. But about a dozen countries, such as Japan, are placing much hope in floating offshore wind as part of efforts to decarbonize their energy sector. Japan’s GX calls for 30-45 GW of offshore wind power capacity by 2040, with floating turbines seen as taking over the wind sector once it gets fully established in the 2030s.
Japan’s energy sector seeks to move away from Chinese supplies after detention
(Japan NRG, Oct 25)
TAKEAWAY: The detention was not an isolated incident. Earlier in October, China formally arrested a senior Japanese executive at pharma company Astellas after detaining him since March on espionage charges. The executive had spent a large part of his career in China and was on the brink of retirement. Earlier this year, China had revised its legislation to broaden the range of activities it considers to be espionage.
In the commodities business, the sharing of data is often part of the process of creating a market. Publishers of international energy price indices rely on market participants voluntarily disclosing details of their deals. Not many Japanese companies take part in the process, but those few who do might now recheck price publisher data management policies. Businesses are improving measures to protect employees as well as data. However, according to Japanese experts speaking at the recent Tokyo-Beijing Forum, there is now uncertainty about where Chinese legal lines lie.

MoE subsidies to push data centers toward increased renewable energy use
(Japan NRG, Oct 25)
TAKEAWAY: Data center power consumption is likely to exceed the MoE’s forecast. Covid-19 led to an increase in data traffic, especially with more video streaming. That traffic will only increase because video is going 3D with the rise of the metaverse and AI-driven “XR” (virtual, augmented and mixed reality) technologies.
TAKEAWAY: Snow does not cost the data center anything, but the labor and fuel cost of collecting and transporting it has an impact, a city official told Japan NRG. Meanwhile, another data center operator said that customers seek resilience against earthquakes and floods, and that emissions are still a low priority.

SoftBank to build data center with Japan’s largest power demand
(Nikkei, October 20)
TAKEAWAY: A report earlier this month estimated that the catchment area served by TEPCO also will require 7 GW of new power capacity over the next ten or so years to meet demand from new data centers. One of the biggest clusters for such new facilities is forming in the city of Inzai, Chiba Pref, which has a population of just over 100,000 but will require 2.5 GW of new capacity by 2035 to meet data center needs. That’s equivalent to building two and a half nuclear reactors. Softbank’s choice of location in Hokkaido should help to support new solar, wind and battery capacity in the region. But the site near Tomakomai will also need to compete for green energy with a new semiconductor hub that the govt plans to establish in nearby Chitose City.
Mitsubishi proposes changes in offshore wind auction and FIP systems
(Government statement, Oct 27)
TAKEAWAY: For years, governments around the world have scaled back the price offered at wind and solar auctions to benefit from over a decade of cost reductions in both sectors. But the last two years or so have seen a marked reversal in costs due to inflation, rising raw materials prices, and supply constraints. In Japan, the cost of wind power is up by almost a third in this time and the industry supply chains are still at an early stage of development. Mitsubishi is clearly trying to get the officials in Tokyo to notice the situation in Europe. Last month, the UK saw no bids entered in its latest round of offshore wind auctions last month after industry players felt the price cap proposed by the government was too low to allow for a profit.
There is another factor worth noting in this development. After Mitsubishi won all three of the major offshore wind projects in Round 1 of Japan’s auctions for the sector, intense lobbying by competitors led to a change of auction rules. One of the main actors in the lobbying was the Japan Wind Power Association (JWPA). Recently, Mitsubishi has left the JWPA. Should the govt accept Mitsubishi’s proposals, it may weaken the negotiating heft of the industry association.
Kobe Steel plans ammonia co-firing at four coal power stations
(Company statement, Oct 26)
TAKEAWAY: The two 700 MW units will consume 700,000 tons/ year of ammonia at 20% co-firing. JERA and Kyushu Electric plan 20% co-firing at 1 GW plants, consuming 1 million tons/ year of ammonia combined. If all coal plants in the country did 20% ammonia co-firing, Japan would need 27 million tons/ year. In 2022, the global ammonia market was 170 million tons in 2022, according to ChemAnalyst, which predicts that it will almost double in the next 10 years or so.

Iridium’s Challenge in the Age of Green Hydrogen
In June, Japan’s hydrogen strategy took a decisive green turn when METI rewrote the 2017 Basic Hydrogen Strategy in order to reflect the International Partnership for Hydrogen and Fuel Cells that seeks to reduce hydrogen’s carbon footprint. METI’s previous stance was that hydrogen of any color was useful in cutting emissions, but now, it leans towards green hydrogen as the optimal solution.
The revised Basic Hydrogen Strategy also introduced a new target for green hydrogen production: 15 GW of renewable-driven electrolyzer capacity by 2030. This is a major leap from the present 14 MW. However, the 15 GW goal brings significant challenges.
One of the most widespread electrolysis technologies globally is proton electrolysis membrane (PEM), but one crucial item in this process is provided by the precious metal iridium. Cost is not even the main issue. The most serious problem is iridium’s severe scarcity amid rapidly growing global demand. In order to satisfy its appetite for PEM systems, Japan alone will need one third of the current total global mined iridium production.
Another problem is the significant carbon footprint of iridium mining, an inconvenient fact that many would prefer to sweep under the rug. It’s estimated that there’s 3,289 tons CO2-equivalent emissions for one ton production of platinum group metals, which includes iridium. Finding solutions to iridium supply and emissions will be fundamental challenges in the growth of green hydrogen in Japan and globally.
Hydrogen investment boom
“Hey, are you investing in hydrogen? The government is giving away money.” These words can now be heard often since the Green Transformation (GX) Act was passed in May, allowing the government to issue ¥20 trillion GX bonds to finance the energy transition, as well as to raise ¥150 trillion more through public and private efforts.
The immediate goal is to fund 15 GW in electrolysis capacity building by issuing GX bonds. This capacity will produce 300,000 tons/ year of hydrogen from renewable energy and water. That is 10% of METI’s goal for 3 million tons of hydrogen supply by 2030. ANRE began internal discussions on funding criteria, which will be finalized by year’s end.
In Japan, the hydrogen production process using water electrolysis has been utilized by the semiconductor industry for two decades or so. There are two technologies: the proton exchange membrane (PEM), also known as polymer electrolyte membrane, and alkaline water electrolysis (AWE).
In PEM systems, water particles pass through the membrane and separate into hydrogen and oxygen after electricity is applied. Iridium is used on the cathode and platinum on the anode. In AWE, sodium hydroxide or potassium hydroxide solution is used. The solution separates into hydrogen and oxygen after electricity is applied. Steel is used as cathode and anode. PEM’s use of precious metals makes it expensive, but it’s capable of accommodating volatile changes in the electricity volume. AWE is cheaper to build but there are questions on how well it copes with sudden changes in output from variable renewable power sources, and if sodium or potassium solution-based systems could be managed easily.
Presently, AWE accounts for two thirds of Japan’s electrolysis capacity owing to a single 10 MW capacity in Fukushima, which is the oldest green hydrogen system operational since 2020. All other recent projects have PEM systems.
Electrolysis capacities in operation
| Project name | Electrolyzer capacity | Electrolyzer maker | Technology
| Energy |
| Fukushima FH2R | 10 MW | Toshiba Energy Systems, Asahi Kasei | AWE | Solar |
| Yamanashi H2-YES | 2.3 MW | Hitachi Zosen, Toray | PEM | Solar |
| Ohbayashi Oita geothermal plant | 0.05 MW | NA | PEM | Geothermal |
| Ishikari City Atsuta Microgrid | 0.005 MW | Takasago Thermal Engineering | PEM | Solar |
| Hokkaido Electric Tomato Atsuma | 1 MW | Hitachi Zosen | PEM | Solar, wind |
Source: Companies information, Japan NRG
In the national hydrogen strategy, METI has positioned PEM and AWE as the main technologies, setting 2030 cost targets: ¥65,000/ kW for PEM; and ¥52,000/ kW for AWE. Japan NRG estimates the present cost to be around ¥500,000-550,000/ kW, based on the amount of the government subsidy given to Hokkaido Electric for its 1 MW electrolyzer.
There are different views on which technology will capture a greater share by 2030. The equipment manufacturers are expanding both PEM and AWE systems, assuming each will have almost equal shares, but with 5-10% also going to novel technologies through the end of the decade.
Supposing that PEM accounts for 40% of the 15 GW capacity to be added – Japan will need to secure as much as 4.2 tons of iridium, over one third of the total globally-mined production, which is between 7 to 8 tons annually. Japan’s electrolysis capacity is seen to account for 10% of the global total.
Japan’s iridium demand in 2030
Data varies on how much iridium a PEM system requires. The World Platinum Investment Council says 400 kg of iridium is required for 1 GW of electrolysis power. Some experts said the iridium requirement could be as much as 700 kg/ GW. Also, iridium electrodes do not last forever, and might end their life cycle after 10 years and need to be replaced.
Based on the conservative estimate of 400 kg consumption for 1 GW, and applying the present market rate of ¥22,900/ gram, the iridium materials cost for 1 kW comes to ¥9,160. This is already 14% of the 2030 target cost of ¥65,000/ kW. The PEM system will also require 0.3 grams of platinum per kW, which comes to ¥1,304.
Iridium is a platinum group metal (PGM), the crude ore of which typically contains roughly 80% palladium and platinum. Iridium’s ratio might be only 1%. South African mining companies Anglo American, Impala, Sibange Stillwater, and Northam account for over 80% of global iridium production.

Source: Company press releases
To build reliable supply chains companies are joining forces. In October, Toshiba Energy Systems and Solutions and Furuya Metal, a PGM trader and recycler, inked a MoU to build an iridium supply chain. Furuya Metal is a Mitsubishi group company with a top global share of ruthenium in terms of trading volume. It also runs a recycling plant in Japan and is one of the few companies capable of recovering iridium from industrial scrap.
Furuya can increase Toshiba’s supplies by improving the recovery rate of iridium from wastes in the PEM system production. For its part, Toshiba claims to have developed sputtering technologies that reduce iridium consumption by one tenth.
Recycling kills two birds with one stone
According to Heraerus, only 20-30% of end-of-life products that contain iridium are recycled. However, if the recovery rate is raised to 80% then global supply can increase by four tons or more.
Iridium recycling is very challenging technologically since only a few grams are used in any one item and the process isn’t easy to scale. In Japan, studies reveal that spark plugs with iridium are sold as ferrous scrap for less than ¥200/ kg since recyclers can’t tell which plugs contain the precious metal.
Recycling also resolves iridium’s other problem: a high carbon footprint due to the fact that its crude ore is smelted in temperatures of 1,500°C, and the work area needs to be cooled. In 2022, Impala Platinum reported to the UK-based CDP, a climate monitoring body for investors, that its Scope 1 and 2 emissions were 354,367 tons for 107.74 tons of PGM production, which comes to 3,289 tons CO2-e per ton of production.
In comparison, hard-to-abate steel scored 1.41 tons CO2-e/ ton of steel, according to the IEA. Heat treatment of recovered iridium occurs at lower temperatures of 1,000°C. Canada’s iridium recycler, McCol Metal, estimates that recycling’s carbon footprint is one third of mining. But 1,000 tons of CO2-e per ton of iridium recycled is still high.
Scientists are exploring chemical processes at lower temperatures, for example the use of solid aqua regia (a mixture of nitric acid and hydrochloric acid) to separate iridium at 500 °C. Another challenge is building an efficient process where different end-of-life products could be treated at once. If successful, then recycling could resolve both iridium supply and carbon intensity problems.
Recycling technology breakthroughs will not happen overnight. On the other hand, cheaper electrolysis technology may emerge unexpectedly. Betting on a single solution would be risky and it is important to keep eyes on other approaches, such as the potential of other platinum group metals to act as iridium substitutes. Other options include reducing iridium consumption, exploring untapped deposits in South Africa, Canada and Australia, and reprocessing mine tailings that may still contain some elements of iridium.
Effective and cost-efficient solutions will have to be found. Otherwise, there won’t be much of a green hydrogen future in Japan, or elsewhere.

Japan’s Long Road to Nuclear Waste Disposal
The proper disposal of nuclear waste is a critical challenge for countries that rely heavily on nuclear energy, such as Japan. Prime Minister Kishida’s pledge to revitalize the nation’s slumbering nuclear industry, shuttered by the March 2011 Fukushima disaster, underscores the necessity of finding a solution this decade.
More than 20 years ago, Japan began a structured approach toward the geological disposal of nuclear waste and formed the Nuclear Waste Management Organization (NUMO) to manage this issue. Since then, the government has struggled to convince suitable municipalities to house the necessary infrastructure.
In recent months, there seemed to be positive momentum around locating a definitive waste storage location. A debate on whether to potentially host such a facility has unfolded on an islet in western Japan. The locality of Tsushima would have been the third to raise its hand as a host candidate in the last three years. However, in the end, turbulent local politics resulted in a stalemate.
Now, all hope rests with the remaining two candidate spots. Both are small settlements in Hokkaido with more than a few challenges, the biggest of which is legislation that effectively bans the movement of nuclear waste into the region. Finding a way around this roadblock, or another town to volunteer as a host, is now center stage in Japan’s nuclear industry.
Legislative and practical issues
After the Fukushima Daiichi nuclear disaster in March 2011, all of Japan’s 17 nuclear power plants, with a total of 54 reactors, were shut down. At the moment, there are 24 reactors scheduled for decommissioning or in the process of being decommissioned.
The Basic Energy Plan sets a target to secure 20% of Japan’s electricity supply from nuclear power by FY2030. To maintain this 20% contribution from nuclear power by 2050, it’s estimated that 10 to 20 new reactors need to be built by mid-century.
In 2000, Japan enacted the Designated Radioactive Waste Final Disposal Act and set up NUMO to manage the geological disposal of both high-level radioactive waste (HLW) and transuranic waste (TRU) generated from Japan’s nuclear fuel cycle. This waste results from reprocessing spent nuclear fuel, wherein reusable uranium and plutonium are separated, leaving HLW and TRU waste.
The HLW is vitrified and encased in stainless steel, preparing it for geological disposal. This entails placing the waste in stable underground locations at least 300 meters deep. The final disposal site surface will cover about 2 km², with underground facilities storing over 40,000 glass pillars containing nuclear waste.

Source: NUMO
Wanted: Volunteer sites for nuclear waste disposal
There’s a three-stage investigation for selecting a final disposal site. The first stage, termed “Literature survey,” entails NUMO collecting region-specific geological data, maps, and academic papers. Next, they assess the geological stability of potential sites by checking for significant vulnerabilities such as volcanic or fault activities, or weak geological layers that could hinder underground construction.
The second step is an “Overview survey” during which boring and other related tasks are made at candidate sites. Finally, a “Detailed survey” is made, coinciding with setting up an underground research laboratory at the planned sites. These three steps can take as long as 20 years in total.
In 2002, NUMO began inviting Japanese municipalities to volunteer as locations to host a nuclear waste storage site. In 2007, Toyo town (Kochi Pref), led by Mayor Tashima Yasuoki, stepped forward. However, his decision was made without consulting the Toyo assembly, which in the end stirred up significant local opposition. The next election was won by a candidate opposing the storage plan, which led to the withdrawal of Toyo’s application.
Just putting up one’s hand can be a windfall for a locality because accepting a survey comes with significant financial incentives. The first phase provides municipalities with up to ¥2 billion, and no obligation to pay it back in the event of subsequent withdrawal. The second phase can involve a total grant of up to ¥7 billion. Despite the lucrative payout, about 15 years have passed without any other municipality stepping forward as a candidate site.
| Survey Phase | Activities | Grant amount | Duration |
| Literature survey | Research using maps, academic papers, etc. | Up to ¥2 billion | About 2 years |
| Overview survey | Bedrock and geology investigation through boring | Up to ¥7 billion | About 4 years |
| Detailed survey | Underground facilities construction | To be determined | About 14 years |
Final site selection process
To spur momentum into the search, in 2017 the central government produced the Nationwide Map of Scientific Features, which delineates areas deemed scientifically and geologically suitable for a final storage of nuclear waste.
Finally, as the impact of the Covid pandemic hit local economies, two municipalities in Hokkaido suddenly stepped forward. In late 2020, survey work began in the town of Suttsu and the village of Kamoenai that applied for a “Literature survey.” Suttsu, with a population of 2,838, and Kamoenai with about 870 residents, resemble many other peripheral Japanese towns with dwindling populations and industries in need of financial resources.
Following METI’s approval of the two towns’ applications, NUMO began surveys in both locations on November 17.

Kamoenai, however, isn’t an ideal place for a storage facility. According to the map, it sits near an active volcano, which leaves only a small southern portion of the village as suitable ground. Suttsu looks more promising. Still, as far as NUMO is concerned, both locations were within areas deemed as potentially suitable based on the 2017 Nationwide Map of Scientific Features. That’s why the agency says it went ahead with the surveys.
Recent developments
Despite NUMO hosting explanatory meetings and a publicity campaign targeting about 160 locations nationwide, the only concrete interest so far has been limited to the two places in Hokkaido. This led to a revision of the Designated Radioactive Waste Final Disposal Act in April 2023, aiming to enhance information-sharing and discussions among the government, NUMO, power utilities, and local municipalities. Starting July, a team of representatives from government and power companies began a nationwide tour in order to expand the regions where the literature review could be conducted.
The group seemed to sway the mood in Tsushima (Nagasaki Pref), a small islet north of Kyushu. The Tsushima City council discussed acceptance of the literature survey, with a pro-acceptance group submitting a petition. After an initial rejection, on September 12 the petition was adopted with a majority of 10 to 8 in favor. However, the final decision on whether to welcome the survey rested with the mayor.
On September 27, the mayor decided not to accept the preliminary survey, citing several reasons such as insufficient local support, concerns about reputational damage to tourism and the fisheries industry, and the inability to eliminate risks from unforeseen factors. NUMO responded to Japan NRG to say that it takes the mayor’s decision seriously, and that nothing has been decided at the current time.
Things seem to be progressing in Hokkaido, however. Initially slated for a two-year duration, the literature surveys in Suttsu and Kamoenai were extended by about a year. What’s more, the local political support seems to remain in place, at least for now.
On October 3, an election was held for the Suttsu town council. Five candidates supporting the survey were elected, ensuring a majority. The town also elected four council members that oppose the survey. Although not directly involved in the survey process, the council, alongside the mayor, will likely have a big influence on how the town’s residents feel about moving to the second stage of the survey process.
What’s next?
Suttsu’s Mayor Kataoka plans a referendum on whether to proceed with the second “overview survey” stage of the process. But even if the residents approve, the town will also need to battle with the Hokkaido governor.
While not required for the first stage, the governor’s approval is necessary to proceed to the second, and Hokkaido Governor Suzuki Naomichi is not a supporter. Suzuki can defend his position by pointing to a Hokkaido Prefectural ordinance that strongly advises that no nuclear waste should be brought into the region.
Interestingly, Hokkaido is the only prefecture with a clear anti-nuclear waste stance. Its ordinance doesn’t prevent municipalities from conducting surveys, but it hints at potential roadblocks that will impede waste importation.
Of course, ordinances and laws can be rewritten if there’s enough reason to do so. If research confirms the sites as suitable locations, then the national government can work on persuading the Hokkaido governor to lessen the prefecture’s opposition.
When the survey began three years ago, both Mayor Kataoka and then-Minister of Industry Kajiyama Hiroshi backed it, saying that the initial phase did not automatically lead to the second stage, and that the literature survey did not contradict the ordinance. This appeared to sidestep the issue and postpone the problems, playing for time.
The stalling tactics could easily backfire. As local mayors wrestle with the dilemma of winning lucrative grants against likely anger from local fisheries and the tourism industry, the chances of a town performing a U-turn on its candidacy are not small. And the further the survey process extends, the more time will be “wasted” if at some point during the 20-year review period the local leadership withdraws its candidacy. Such a turnaround could easily be sparked by personal conflicts or local politics.
The government’s softly-softly approach looks good enough to reach ‘first base’. But to score a ‘home run’ and secure a viable long-term solution, officials may have to alter their tactics.

Below are some of last week’s most important international energy developments monitored by the Japan NRG team because of their potential to impact energy supply and demand, as well as prices. We see the following as relevant to Japanese and international energy investors.
AI/Energy demand
According to Schneider Electric, (with the exception of China) AI consumes about 85-134 terawatt-hours (TWh) of electricity across the globe each year, which is about as much as the Netherlands’ energy consumption. This figure could grow five-fold by 2028.
China/Renewable energy
China’s renewable energy expansion can’t keep pace with demand even though the country added 226 GW of generating capacity in 2023 – solar (129 GW); thermal (39 GW); wind (33 GW); and hydro (8 GW). Thermal plants are generating far more hours on average (3,344 hours) than hydro (2,367 hours), wind (1,665) and solar (1,017 hours), according to the National Energy Administration.
France/Hydrogen power
Air Liquide, one of the world’s largest hydrogen producers, plans to invest €3.4 billion over the next 12 months, with half going to projects in the U.S. where it plans to become a leader.
Italy/CCS
Gas grid Snam and Eni plan to capture CO2 and store it in depleted gas fields, betting that French companies, such as cement and steel makers, will store their CO2 in the Italian hub instead of Norway’s CCS facilities. The first phase launches by early 2025 to store 25,000 tons of CO2 a year in depleted gas fields offshore Ravenna.
Qatar/Natural gas
QatarEnergy inked a deal to sell 1 mtpa of LNG supply to Italy’s Eni for 27 years starting 2026. The volumes will be sourced from expansion of the North Field East (NFE), one of the world’s largest gas fields, which will increase LNG production from 77 mtpa to 110 mtpa. With the North Field South (NFS) phase, Qatar plans a capacity of 126 mtpa by 2027.
Russia/Natural gas
Gazprom will supply extra gas to Hungary this winter, and will provide China with an additional 600 million cubic meters this year on top of contractual obligations. President Putin met the leaders of both countries during a trip to China last week.
Offshore Wind
General Electric expects its offshore-wind operations to post annual losses of about $1 billion for this year and in 2024 as the industry struggles with rising costs. Next year, the company expects offshore will have similar losses but “substantially improved cash performance.”
Singapore/Natural gas
Singapore will set up a single buyer of natural gas for its power-generation sector to improve energy security. This entity will aggregate gas demand from the power-generation companies (gencos), then import the gas required, and sell it to the gencos.
Sweden/EV batteries
Northvolt, Europe’s largest battery maker, could go public next year, but the plans are still preliminary. The Swedish battery maker has invited investment banks to pitch for roles in the deal that could value the company at about $20 billion.
Venezuela/Oil
A U.S. judge will hold an auction of Houston-based Citgo, which is owned by Venezuela. For the past four years, the U.S. protected oil refiner Citgo Petroleum from creditors seeking to seize Venezuela’s foreign crown jewel for billions of dollars in claims.
U.S./Oil
Chevron will buy rival Hess for $53 billion; the deal reflects energy companies’ bid for oil and gas assets. The deal intensifies competition between Chevron and Exxon, but they’ll now be partners in Guyana’s booming oil fields expected to produce 1.2 mbpd by 2027.
