ANALYSIS
‘BLUE’ VS ‘GREEN’ HYDROGEN AND ITS IMPACT ON JAPANESE POWER SECTOR
The debate over the economic feasibility of ‘blue hydrogen’ vs ‘green hydrogen’ is approaching a decisive moment, and developments in the State of Texas are at the center of this issue. How it is resolved will impact Japan’s power sector decarbonization in general and Japan’s largest utility, JERA, in particular, as it envisions upgrading coal-powered thermal plants to run on ammonia.
HOW JAPANESE STEEL IS TURNING GREEN:
PART II
The steel sector will get almost 50% of state green R&D funding over the next ten years. Price is one of the main factors that will influence the next steps in ‘green steelmaking’. In this second part we look at how the steel sector and the government are wrestling with disparities between what they ‘need’ the price of clean steel technologies to look like and what they are in practice.

METI panel publishes 2040 industrial strategy paper, with focus on growth opportunities
(Government statement, April 24)
TAKEAWAY: The paper hints at the potential for Japan’s carbon credit markets to be linked to similar exchanges or programs in other countries. At this point, this is just a mention in a broader strategy paper that has far-off targets and little substance. However, it points to the direction that some in govt and business believe Japan should take – creating an international carbon credits marketplace, which would see CO2 reductions in one place credited / traded in another.
Aomori Pref will start drafting a tax ordinance on renewables
(Japan NRG, April 25)
Japan, EU to set common rules on net-zero programs, public procurement
(Nikkei, April 25)
TAKEAWAY: It may be possible to exclude some generic or commoditized made-in-China products from the market. But it will be challenging to block Chinese products that are highly innovative and not found in Japan, EU or the U.S. In some sectors, Chinese companies’ R&D spending exceeds that of Japanese businesses even without government subsidies. Even in the more commoditized areas, non-Chinese producers will need to show they have a competitive offering.
TAKEAWAY: In a typical mutual authentication agreement with the EU, the parties review each other’s systems periodically. Extending this framework to hybrid vehicles, as well as drawing a line between “recyclable minerals” and “chemicals with marginal mineral elements that can’t be recycled”, etc. may be possible discussion points.
PM Kishida to visit Brazil, sign decarbonization partnership
(Asia Nikkei, April 25)
TAKEAWAY: Japan Biofuels Supply, a JV of five local oil refineries, currently dominates biofuel import trades. Market entries triggered by bilateral initiatives will not only change the trade landscape but will also create a need to explore ways to price biofuel imports. There is no commodity index for the Japanese biofuel market.

Okinawa’s caustic soda plant to commercialize hydrogen supply
(Japan NRG, April 22)
TAKEAWAY: The national govt will fund ¥156 mln for building the hydrogen transport and storage facilities, which equates to ¥354/kg of hydrogen, assuming that the facilities will be used for 20 years. This is just about at the 2030 target cost of ¥30 /Nm3 set by the govt.
Number of EV charging outlets surpasses 40k, up 25% from a year ago
(Government statement, April 22)
TAKEAWAY: EV charging outlet growth has outpaced that of EV sales, which were 40,327 units in FY2023, up from 35,559 in the previous period. Sparse charging infrastructure was blamed for slow EV sales, which accounted for only 1.6% of total passenger car sales.

BESS wins big in Japan’s first long-term decarbonized power auction
(Japan NRG, April 26)
TAKEAWAY: Despite renewables industry concerns that nuclear power would benefit the most from this new auction, the greatest capacity allocation (outside LNG) actually went to BESS and pumped hydro. The latter are both geared towards energy storage, rather than generation per se, which highlights the govt’s interest in securing more energy storage to balance the grid amid a wider rollout of variable renewable energy sources.
The results also indicate a willingness to grant allocations for smaller-scale BESS projects, which should support the sector as it starts to develop from its low base in Japan. BESS and other energy storage options will likely have even greater allocations from FY2026 when the govt is due to stop accepting bids for LNG-fired capacity. With a 20-year guarantee for fixed revenues, the auction is expected to prove a popular option for BESS operators. While only 24% of BESS bids were successful this time, the fact that 4.56 GW of BESS capacity was tendered bodes well for the sector’s development over the course of this decade.

Genkai Town mulls putting hand up to host nuclear waste final disposal site
(Japan NRG, April 26)
TAKEAWAY: Since NUMO started the search for a final disposal site more than 20 years ago, only two localities (Suttsu and Kamoenai, both in Hokkaido) have started the process. The Hokkaido municipalities are now in the second stage of the review process.
Accepting the survey brings state funding to the municipality, which helps revitalize the local economy. Yet, according to a state map indicating potential waste storage site locations, Genkai is not suitable. Even if the town’s authorities overcome any opposition from residents and the prefectural governor, and the survey goes ahead, there’s no guarantee it will ever be completed. The entire three phases could easily take more than 10 years, leaving space for cancellation.
Chugoku Electric begins surveys for spent nuclear fuel interim storage facility
(Company statement, April 23)
TAKEAWAY: The Kaminoseki interim storage facility is crucial for both Chugoku Electric and KEPCO. If the surveys continue and the facility is built, Chugoku Electric could use it for its Shimane NPP. Also, it can help KEPCO fulfill promises to ship spent nuclear fuel out of the prefecture – promises that underpin its current NPP operations.

Mitsui & Co. might join $7 billion LNG project in UAE
(Nikkei, April 23)
TAKEAWAY: After Nikkei reported the discussions of this deal, Mitsui issued a statement saying a final decision has not been made. One is likely to be made in May. If so, it would mark a slight resurgence in Japanese LNG investment over the past six months or so. In early April, Mitsui’s biggest domestic rival, Mitsubishi Corp, agreed to invest in MidOcean Energy, an LNG firm owned by U.S investor EIG and with stakes in a number of Australian LNG projects. In February, JERA committed $1.4 billion to the Scarborough gas project in northwest Australia that’s being developed by Woodside Energy, following a $880 million investment in the same project by LNG Japan, the JV between trading houses Sumitomo Corp and Sojitz. Mitsui itself extended its involvement in an Oman LNG project just in October 2023.
Such a concerted effort to invest in new and existing projects, which has included several in the U.S., suggests that Japanese buyers see a slightly different demand picture to the one painted in the country’s Basic Energy Plan. The current version of the Plan says LNG use in power generation will drop by half by the end of this decade in Japan. The Plan is due to be revised this year.

Blue vs Green Hydrogen and its Impact on JERA
The debate over the economic feasibility of ‘blue hydrogen’ versus ‘green hydrogen’ appears to be approaching a decisive moment in the global conversation about clean forms of energy. And developments in the U.S., specifically the State of Texas, are at the center of this issue.
Those espousing green hydrogen say that the best solution is to focus on total emission reductions from the very start. Meanwhile proponents of blue hydrogen say that it’s more important to allow low-carbon facilities and infrastructure to be built and scaled quickly.
In the past few months, private opinions have made their way into the public realm, with directors of major legacy energy companies criticizing green hydrogen as economically infeasible because of high production costs.
Instead, they’re pushing for blue hydrogen as a low-carbon solution to meet current market demands. Blue hydrogen is made from natural gas, while green hydrogen, which has more backing from G7 governments, relies on electrolyzing water with solar or wind power. Hydrogen and ammonia do not emit CO2 when burned.
How this issue pans out will impact Japan’s power sector in general and Japan’s largest utility, JERA, in particular, as it envisions upgrading coal-powered thermal plants to run on ammonia. JERA needs the ammonia to have as little carbon footprint as possible to claim that its strategy is “clean”. But it also needs the new fuel to be affordable and available at scale. As such, the outcome of the debate in Texas will have a bearing on both the economics and the optics of Japan’s power sector decarbonization.
Ammonia co-firing with coal
JERA, which is a 50/50 joint venture between TEPCO and Chubu Electric, produces nearly 30% of all electricity in Japan. The company has 26 coal-fired power plants, mostly in and near the cities of Tokyo, Kawasaki, Yokohama, and Nagoya.
At the start of this month, JERA started what it claims is a world-first demonstration of the co-firing of ammonia and coal at a large-scale, commercial thermal power plant. Should it go well, by 2027 JERA aims to implement ammonia co-firing on a regular, commercial basis at its Hekinan power station.
In 2028, the ratio of ammonia in the fuel mix at one of the units of the Hekinan power station would be raised to 50%. JERA wants to gradually increase the ammonia ratio, eventually reaching 100% in all its coal power plants at home, and possibly export the technology to countries in Southeast Asia. The timeline on these plans extends into the 2030s.
While JERA is also actively expanding into renewable energy, and launched its brand new global renewables subsidiary JERA Nex earlier this month, the company’s decarbonization strategy largely rests on shifting existing thermal plants from fossil fuels to clean-burning ammonia or hydrogen. To do that, JERA needs to create a global ammonia supply chain since the vast majority of the ammonia produced today is used to make fertilizer and there’s little spare capacity at existing facilities.
Toward that goal, JERA has inked a number of deals with major ammonia producers. Of these, just one is for green ammonia – the agreement with India’s ReNew E-Fuels. The scale, however, is relatively small: just 100,000 tons of ammonia / year.
All the other projects that JERA has explored to date are based on the ‘blue’ approach, which involves steam reforming of natural gas, and capturing the CO2 that’s created in the process.
In the blue ammonia space, JERA has many more options in terms of suppliers and volumes. JERA is in talks with the world’s top ammonia producer, CF Industries in the U.S., and Yara Clean Ammonia, a unit of Norwegian chemicals giant Yara International. Both are planning new ammonia production lines situated along the U.S. Gulf coast, each possibly producing more than one million tons annually.
JERA might take a stake in the Gulf coast projects, as well as sign an offtake contract for as much as half a million tons of ammonia a year. JERA Chairman Kani said that he’d like to see “at least double-digits” stakes when investing in U.S. ammonia projects.
The project that has perhaps become the focal point in the blue versus green ammonia / hydrogen discussion, however, is ExxonMobil’s Baytown Complex in Texas, where JERA is also exploring participation. That project hopes to produce 900,000 tons of hydrogen per year, which would be used to produce about one million tons of ammonia.
ExxonMobil claims that the Baytown Complex will be the world’s largest facility of its kind, and hopes to begin production as soon as 2028. But the multi-billion-dollar investment decision on the project depends in large part on how much the operator can secure in U.S. subsidies. According to ExxonMobil, it needs the subsidies for its blue project to be closer to what the government offers for green projects.
If Exxon wins, this could help decide the outcome of the blue versus green ammonia debate, at least for the near-term. If they lose, companies like JERA might slow their shift from coal to ammonia, fearing a lack of adequate (and affordable) supply.
Color hydrogens do battle
When JERA announced plans to start commercial-scale co-firing at one of the units of its Hekinan coal power plant, it put out a contract offer in 2022 for 500,000 tons of ammonia supply per year. This was possibly the largest ever ammonia contract outside of the fertilizer sector. And yet, this volume would only cover one year of operations at one unit of one thermal power plant at the co-firing ratio of 20% ammonia – 80% coal. Effectively, ammonia would fuel 200 MW of capacity.
For the power company to ramp up to 50% ammonia firing, and to spread the technology to other thermal power plants, it will need to lock in a serious amount of fuel supply. Projects like the Baytown Complex offer this kind of scale, but according to Exxon it needs tax credits for it to work commercially.
The U.S. government’s Inflation Reduction Act (IRA) was passed to address this exact issue – of bridging the cost gap with existing fuel sources. However, the IRA strongly favors green hydrogen. Under the IRA, the amount of tax credit declines as CO2 emissions increase during production. Exxon wants the IRA to treat blue and green hydrogen as equals.
Move now or wait for Green H2?
Over the past several months the heads of major companies such as Exxon, Saudi Aramco and trading company Gunvor have gone public with their thoughts that the high cost of green hydrogen production will prevent it from displacing oil and natural gas any time soon. And waiting for green H2 to arrive would delay the energy transition.
Saudi Aramco CEO Amin Nasser says that the cost of green hydrogen is equivalent to $400 for a barrel of oil, which is roughly four times the current price. To make green H2 work, it needs sizable state incentives and offtake agreements of at least 15 years.
Meanwhile, Exxon CEO Darren Woods told the CERAWeek energy conference that clients were not yet prepared to pay for the costs associated with emissions reductions. As such, Woods said he could only see Exxon producing hydrogen if the IRA guidelines were amended to allow tax credits for methane-derived hydrogen.
International fertilizers and chemicals giant OCI Global said resolutely that it will move forward with hydrogen, but in its ‘blue’ format. The company is building one of the world’s largest blue hydrogen-derived ammonia plants in Texas, to cost nearly $1 billion.
“We’re not going to pause our business just to wait for this technology [green hydrogen] to scale, which we think will take five or ten years,” said Bashir Lebada, head of OCI’s methanol and fuels business.
Conclusion
As a buyer, rather than producer, JERA and other Japanese companies that are keen to use ammonia are largely agnostic on the colors of hydrogen and the production methods. At the same time, Japanese buyers can only invest in and sign offtake deals with projects that are deemed feasible and that deliver at scale.
Whether blue ammonia or hydrogen emerges victorious in the U.S. thanks to the lobbying efforts of Exxon is not something that Japanese buyers will affect. Still, the desire of JERA and others to move to ammonia firing sooner, rather than later, could play a role in the debate.
The irony of ever greater pressure on companies to decarbonize quickly may be that it brings more ‘blue’ options to the fore as realistic pathways, while pushing ‘green’ options into a supporting role.
BOX: The math of subsidies
The Department of Energy has said it will award up to $8 billion in grant funding to develop several hydrogen hubs across the U.S. In December of last year, the IRA set up a Clean Hydrogen Production Credit program that has four technology-neutral credit tiers based on the emissions rate of various hydrogen production processes.
To qualify, hydrogen must be produced with less than four kilos of CO2-equivalent per kilo of hydrogen. The guidelines on production, however, only refers to green hydrogen.

The credits are offered only to projects that can begin construction by 2033, and are valid for 10 years starting when a hydrogen production facility enters service. The credit ranges from $0.60 to $3 per kilo of hydrogen produced, depending on the lifecycle emissions of the hydrogen production.
The U.S. energy strategy calls for hydrogen to be produced for $1 per kilo by 2031. Today, the levelized cost of green hydrogen is over $4 per kilogram, according to Bloomberg New Energy Finance, but it could meet the national target should the project qualify for the maximum credit amount.
In the case of blue hydrogen, however, most projects would only be able to qualify for a tax credit of up to $1 per kilo, bringing the cost range of blue H2 to $1.0-$1.5 per kilo. As such, the U.S. Department of Energy estimates that most blue hydrogen will exceed the $1 target by 2031. The DOE also casts doubt on whether most blue projects will meet the criteria for ‘clean hydrogen’ and thus qualify for credits.
The saving grace for blue hydrogen, however, may be an additional tax credit known as 45Q, which provides up to $85 per ton of CO2 that’s captured and permanently stored. Making the subsidies math work will be Exxon’s priority in the coming year or so.

How Japanese Steel is Turning Green
Part II : Reducing the Problem to its Core
If Japan’s fully behind a hydrogen economy, then it’s even more fully behind a net-zero shift in steelmaking. For all the headlines around the ‘hydrogen economy’, the steel sector is due to get almost 50% more government green R&D funding (¥427 billion) over the course of the next ten years.
Of course, hydrogen will play a vital role in the transformation of steelmaking from the centuries-old process based on coking coal. But it’s not the only component in what is widely touted as the age of ‘green steel’. A number of innovations are in the works in Japan’s steel factories, both in heat control, emissions absorption, and power sources.
Nearly all the new technologies proposed and tested are still in the pilot and demonstration stage, but the development is further advanced than most realize. One of the biggest factors that will influence the next steps in ‘green steelmaking’ is the persistent conundrum of price. After all, technological breakthroughs will mean nothing if they can’t find willing clients and supportive governments.
In this second part of the “Green Steel in Japan” series, we look at how the steel sector and the government are wrestling with obvious disparities between what they ‘need’ the price of clean steel technologies to look like and what they are in practice. The next few years require radical mind shifts, either on the side of producers or buyers, or both.
Another way to make steel
In the first part of this series, we looked at the way the majority of steel is produced in Japan – via iron ore use in blast furnaces. There is another steelmaking process that involves hydrogen that’s known as direct iron reduction (DRI). This approach uses shaft furnaces, which operate at a lesser temperature than the blast furnaces, but still require 900-1,000 C.
The DRI method relies much more on hydrogen as the sole agent for iron reduction. In this approach, the natural gases in the furnace comprise 60-80% hydrogen. Presently, around 10% of the world’s steel is made using natural gas as a reducing agent. It’s especially popular in the Middle East and the U.S. where natural gas is abundant.
In Japan, JFE Steel tested natural gas-triggered reduction two decades ago but stopped due to economic reasons. However, Japanese steelmakers have access to this technology overseas. Kobe Steel’s U.S. affiliate Midrex Technologies is the world’s largest shaft furnace builder. Kobe acquired Midrex in 1983.
Last year, the Japanese steel sector became more active in examining how DRI could be more widely used. Kobe Steel tested how the technology can be applied to its Japanese blast furnace-dominated facilities. The company used DRI at its Kakogawa furnace, deploying the method to pre-treat iron instead of iron ore. As a result, Kobe Steel reported a 25% CO2 reduction compared to the usual process of treating iron ore from scratch.
Meanwhile, JFE Steel has started construction of a small 15 kg of iron ore per hour shaft furnace at its Chiba Works, and plans to begin test runs in FY2024. In 2025, Nippon Steel will set up a 1 ton per hour shaft furnace at the Hasaki R&D Center.
Quality issues
Ore quality is a major challenge for Japanese steel firms keen to employ DRI. Ore with a high iron content of 62-65% fits DRI better. Such ores are found in the Nordic regions and South America. Japanese firms, however, tend to import Australian and Brazilian ores of grades that are in the region of 58-65% iron content, and these are less suitable for DRI.
The above is one region where European competitors such as Thyssenkrupp and SAAB have raced ahead in green steelmaking. With better access to DRI-ready ores, Thyssenkrupp and SAAB say they can commercialize green steel that uses hydrogen as early as 2026-27.
Barring a complete switch of iron ore supplies, which would be a multi-year and vastly expensive process, Japanese steelmakers need to make the DRI process work with the raw materials that they can already access. As such, JFE Steel has embarked on experimentation of DRI with ores of lower iron content (i.e., 58-62%). It has been the most adventurous of Japan’s steel firms in this regard, trialing tactics such as directly feeding low-grade chromite and molybdenum concentrates into the furnaces to compensate for weaker iron concentration.
Unfortunately for JFE, this approach has not yet yielded fruit. It has resulted in massive releases of sulfuric gas, and so the steelmaker has to find other options.
Other technological steps also need revising. The process after removing oxygen from iron ore also needs a re-think. After heating, the metallic iron in blast furnaces melts and becomes more malleable. The hot near-liquid metal can be easily moved to the next process of refining, rolling and shaping. Meanwhile, iron created with hydrogen treatment is not as easily manageable.
Last year, a new project was added to the Green Innovation Fund program, which is to develop a new furnace called a “melter” for treating the iron after DRI. Over the past winter, the government solicited proposals from companies keen to develop such a new furnace, and in April awarded the project to Nippon Steel and The Japan Research and Development Center for Metals.
FY2028 is the deadline to complete development of an 880,000 ton per year DRI production process and equipment. GIF will provide ¥23 billion. By 2030, the Super Course50 method should be operational at Nippon Steel’s Kimitsu Works and Course50 elsewhere.
Calculating H2 demand
Whichever approach Japanese steelmakers use – DRI, Course50, or similar – the common component underpinning the plans is hydrogen.
The Japan Iron and Steel Federation (JISF) believes that steelmakers will need 1,000 Nm3 (90 kg) of hydrogen for one ton of steel in blast furnaces, while DRI would require an additional “several hundred Nm3”.
These numbers are higher than the estimates for hydrogen-based green steelmaking in Europe, with the EU studies quoting figures as low as 50 kg. However, each company’s furnaces are set up differently, and the quality of iron ore, as well as other processes, can impact hydrogen requirements.
– Assuming that Nippon Steel fully switches its 5.7-million-ton a year Kimitsu Works to the Super Course50 method, it would require about 500,000 tons of hydrogen a year.
– Based on JISF guidance, Japan NRG assumes that the DRI process in Japan would require 1,300 Nm3 (117 kg) for one ton of steel. That would mean that a one-million ton per year shaft furnace needs 100,000 tons per year of hydrogen.
These numbers are, of course, a maximum projection. Actual demand would be much lower since blast furnaces with current Japanese technologies would not run on 100% hydrogen.
Cost
JISF also says that the steel sector needs hydrogen prices at ¥8/ Nm3, which is less than half of the already low ¥20/ Nm3 government target for 2050. The numbers are completely divorced from the current prices offered by hydrogen producers, which see even the government’s target as already unrealistic under today’s costs.
One way that the market and steel companies may bridge this gap, however, is by changing the criteria for what kind of hydrogen is needed for steelmaking.
Blast furnaces are inhibited by various gases. As such, unlike fuel cells, furnaces do not require hydrogen of 99.97-99.99% purity. They may tolerate 80% hydrogen so long as it is sulfur-free. This opens opportunities for producers to make cheaper, low-purity gas that would create a new tier in the hydrogen market.
If this tier gains momentum, through being accessible in price for Japanese steelmakers, this could become the hydrogen product that is more likely to drive near-term demand, and thus act as a benchmark for both low and high-purity hydrogen contracts in Asia.
It’s likely that the European and North American markets will evolve differently, due to their widespread plans for DRI based on higher iron ore grades. Still, even those steel producers will have to adapt. The world’s iron ore deposits tend to average 56-57%.
Similarly, there is a lack of clarity over the type of hydrogen required for DRI that JFE Steel plans to explore in its studies around low-grade iron ores.
Japanese steelmakers building DRI-enabled shaft furnaces may use natural gas as the reduction agent in the interim until hydrogen prices reach realistic levels. This could lead the steel sector to pursue a similar kind of dual-fuel strategy to that currently tested by the power generation sector.
High hydrogen costs could also push steelmakers to increase their reliance on carbon capture. According to the 2021 Japan Science and Technology Agency policy proposal, the estimated cost of carbon capture and separation is ¥15/ kg, provided that carbon released at blast furnaces is captured fully.
The cost of pig iron production, without carbon capture, was ¥40-50/ kg. Reducing the capture cost will definitely help make Japanese steel greener.
Conclusion
With so many variables, it’s too early to call what ‘green steelmaking’ will eventually look like, with many regional and company variations. The multitude of approaches shows that there are at least a few pathways to reducing the CO2 footprint of the steel sector and that these may be more local than global.
Japan’s steelmakers are likely to continue signaling their intent to move towards a hydrogen-based future for their industry. But they know that they have (and must pursue) other options. The technological battle is still wide open.

This weekly column focuses on energy events in Asia and the Pacific
ASEAN / Energy transition
Regional collaboration through power interconnectors, hydrogen networks and energy storage could reduce the cost of decarbonisation among ASEAN member states by $800 billion, says a report by DNV.
Australia / Renewable energy
The govt launched a 6 GW renewable energy tender for the National Electricity Market under the Capacity Investment Scheme, the country’s largest renewables tender. About 2.2 GW of capacity, which could power over one million households, is planned for New South Wales.
China / Carbon market
Fitch Ratings said that China’s government could reduce the free emission allowance for key emitters and place a cap on the quote that can be carried over to 2025. The expected tightening of China’s national carbon market could drive demand for renewable energy.
China / Coal power
China’s coal-fired power sector is set for another year of profit as coal prices drop, reports S&P Global Ratings. Spot coal prices domestically and internationally were down by about 11% due to abundant supply. In Q1 of 2023, the average spot price was 4% to 5% lower than 2023’s annual average.
EVs
In 2024, EV sales in China are projected to reach 10 million, about 45% of total car sales. In the U.S., about 11% of cars sold are expected to be EV. In Europe, despite the phase-out of subsidies, EVs might account for about 25% of cars sold.
Indonesia / Energy transition
The country’s sovereign wealth fund, the Indonesia Investment Authority, will invest up to $1 billion in 2024. Green energy will be a priority, such as investment in the EV ecosystem and geothermal energy, and financing early retirement of coal-fired power plants.
Malaysia / Oil & Gas
Malaysia’s Sapura Energy will sell its entire 50% stake in oil and gas upstream company SapuraOMV to TotalEnergies for $705 million. The deal, which includes a cash payment of $530 million, will leave TotalEnergies as the sole owner of SapuraOMV
Offshore wind
The global offshore wind sector added an additional 9.8 GW capacity in 2023, across 25 new offshore wind farms, according to World Forum Offshore Wind. In 2022, that figure was 9.4 GW. Now the total global offshore wind capacity is 67.4 GW.
South Korea / Oil & Gas
The Korea Energy Terminal, a JV between Korea National Oil Corp (KNOC) and utility SK Gas, launched a new oil and gas import facility. Located in the Ulsan Free Economic Zone, the facility will also become a center for hydrogen technology development.
Taiwan / Offshore wind
Ørsted launched the Greater Changhua 1 and 2a offshore wind farm, with a total installed capacity of 900 MW, making it East Asia’s largest offshore wind project.
