Mizuho Financial Group to provide assistance to shut down coal plants in SE Asia
(Nikkei Asia, May 21)
TAKEAWAY: Japanese banks, including MFG, pledged to cut coal financing by 2040. MFG has already reduced its coal sector financing from ¥300 billion in 2019 to ¥236 billion in 2022. MFG has come under criticism from NGOs since it is ranked as the biggest private lender for new coal power plants worldwide. It made $16.8 billion in direct loans to coal plant developers in 2017-2020. There have also been online campaigns targeting MFG. The other major Japanese banking groups, Mitsubishi UFJ Financial Group and Sumitomo Mitsui Financial Group, have faced similar criticisms. Investments in coal power plants were focused in Vietnam, Indonesia, and Bangladesh. Now MFG is trying to improve its image and decarbonization efforts.

Ammonia or Methanol: Which is the Winning Zero-Emission Ship Fuel?
Decarbonizing the maritime transport sector counts as one of the most important tasks in the energy transition. Each year, global shipping leaves an emissions trail greater than that of the world’s passenger car fleet. To green this sector, the maritime industry is seeking the most effective and viable solutions.
In FY2022, Japan’s CO2 emissions from the shipping sector were 10.1 million tons, which excludes oceangoing vessels that are not included in the national greenhouse gas inventory. Oceangoing shipping accounts for about 2% of total global emissions.
The International Maritime Organization (IMO) has set a goal to cut emissions by 40% in 2030 from 2008 levels. According to ClassNK, in order for Japan to meet this target, a quarter of its shipping fuel needs to avoid creating a CO2 footprint; and, the country needs new ‘zero emission’ ships.
Among the various clean energy solutions considered, the main one focuses on which fuel should replace the heavy marine fuel oil currently used by vessels. Candidates include ammonia and methanol, but there’s also talk of shifting to synthetic methane and bio-derived fuel options.
Among fuel alternatives, the degree of carbon reductions differ, as does the speed at which they can be introduced to the market. This analysis assesses the readiness of new shipping fuel candidates in the regulatory, ship development and supply aspects.
Agreements in place, but logistics are not
In the past six-months, Japan’s shipping sector has moved to accelerate the shift to ammonia and methanol from fossil fuels. In December last year, the city of Yokohama and Mitsubishi Gas Chemical signed a Memorandum of Understanding (MoU) with global shipping firm Maersk to explore green methanol bunkering in the port of Yokohama.
In April, the world’s second largest methanol-fueled container vessel, owned by Maersk, made a port call. In June, NYK Lines will begin operation of the world’s first ammonia-fueled tugboat in the Tokyo Bay area, which includes Yokohama.
Japan has 932 ports, and any ship fueled by ammonia or methanol is able to enter any port, and offload and load cargoes. While port authorities have no right to block the entry of such ship entries, they won’t be able to re-fuel. Presently, most ports only have the capacity to supply marine residual fuel. About 4 million kiloliters/ year (25 million barrels) of marine residual fuel is used for ships in Japan.
Japan has no facility to serve other fuels, including LNG, and there are only two vessels for LNG bunkering. Onshore storage facilities and bunkering vessels for ammonia and methanol can’t be built because of a lack of clear operational and safety rules specific to filling ammonia and methanol into ship fuel tanks.
Compared to methanol or methane, ammonia has low flammability but it’s hazardous, causing death if direct exposure exceeds 5,500 ppm. Methanol is highly flammable, but its health risk is much lower compared to ammonia.

Regulatory information gap
Relevant laws on ship refueling are the Ship Safety Act, the Act on Port Regulations and the Act on Prevention of Marine Pollution and Maritime Disasters. In 2013, the Ministry of Land, Infrastructure, Transport and Tourism (MLIT) wrote LNG bunkering guidelines to supplement those first written almost 90 years ago. The guidelines were updated in June 2023.
Following consultation with the Japan Coast Guard, which has oversight over the Act on Port Regulations, the MLIT is expected to write similar guidelines for ammonia and methanol bunkering.
In 2022, ClassNK published proposed guidelines on ammonia and methanol ships that could serve as the basis for MLIT’s guidelines. It recommended fuel tank design, piping, ventilation, alarm systems, etc that are relevant to ship structures, but they don’t address issues outside ship design, for example specifying mandatory reporting.
Availability of ships
Municipalities with ambitions to build ammonia supply chain networks by winning national government subsidies are hoping for the early release of ammonia bunkering guidelines. Some industrial stakeholders, however, believe that methanol bunkering could be more practical. ClassNK said that since ammonia is highly toxic, all possible risks must be considered; while other fuels won’t require intensive risk analysis.
As opposed to liquid ammonia that’s stored at -33 C, methanol is stored at room temperature. Present facilities for fuel oil storage and delivery could be used for methanol, which greatly reduces costs. Another methanol advantage is that merchant fleets are already using the fuel for commercial operations.

NYK Bulkship owns three dual-fuel ships that will operate on marine residual fuel oil and methanol. Although small, there is demand that’s poised to grow as orders for dual-fuel ships continue to rise.
Meanwhile, developments on the ammonia front are also making progress. In June, Sakigake, the world’s first ship fueled by ammonia will make its first sail in Tokyo Bay. Sakigake is a tug boat owned by NYK Lines with a gross tonnage of 272 tons.
It was originally an LNG-fueled vessel, converted to ammonia specifications by IHI Power Systems. Marine residual oil (grade-A heavy fuel oil) will ignite the engine and then Sakigake will be fueled entirely by ammonia during its journey.
Shin Nippon Kaiyosha, a NYK group company, will operate Sakigake, with its crew of two or three. The market, however, will have to wait until 2028 to see construction of a fully-fledged ammonia-fueled ship that’s completed and ready to sail.
Fuel availability
Currently, over 90% of the world’s methanol production uses natural gas as feed. While it is effective in reducing sulfuric and nitrogen oxide emissions, its carbon footprint is only 15% lower than that of fuel oil. It would need to be replaced by ‘green’ methanol, which is either bio-based methanol or made from renewables-derived hydrogen.
One shipbuilder told Japan NRG that the global green methanol supply chain is not as robust as for ammonia, and that if demand outstrips supply then methanol for zero emission maritime fuel might not be economically sustainable.
Japan has 1 million tons/ year of domestic ammonia production, and it imports all of its methanol requirements of 1.8 million tons/ year. Each year the country will need about 7 million tons of green methanol in order to replace the current annual consumption of 4 million k of fuel oil.
Using CO2 and hydrogen from chemical plants, Japan’s leading methanol manufacturer, Mitsubishi Gas Chemical, plans to produce green methanol in the Mizushima industrial zone (Okayama Pref). The goal for annual output is 100,000 tons by 2030.
Will the government offer the same level of support to build a global green methanol supply chain like it is doing for ammonia and hydrogen? That will depend on international trends, said a MLIT official.
As methanol gains traction in the global shipping industry, Japan will seek to expand its market share there. But for the time being, the government will also continue to support the growing penetration of ammonia, pinning hopes that either one or both of the fuels – with Japanese technology embedded in the supply chain – will turn out to be a game changer.

Mo’ Power, Mo’ Problems? Japan’s Chip Revolution is
Reversing Power Demand Picture
As Japanese energy planners sit down this spring to update the nation’s strategy, there’s one key assumption they need to rethink entirely. The sixth iteration of the Basic Energy Plan, ratified in October 2021, forecasted that electricity demand would fall 10% this decade thanks to greater efficiency and more conservation. Few would argue that today.
In the last two years, an ambitious state push to revive semiconductor manufacturing in Japan has yielded fruit. The world’s biggest chip maker, Taiwan’s TSMC, opened its first fabrication plant in Japan in late February. As if by coincidence, after 24 straight months without electricity demand growth, March 2024 saw national power consumption tick up. And again, in April.
Within three years, at least two more major semiconductor fabs will open in Japan. Many more facilities that produce components, materials, and equipment for the chip plants are also in the works. That, and the rapid rise of generative AI usage, as well as Japan’s courting of global data centers, could see power demand for the digital sector alone jump by a factor of 10 in a matter of a decade, according to early estimates.
While Prime Minister Kishida’s government has fully backed the semiconductor and AI push, there’s been much less effort to grasp how this will impact the electricity system. Japan’s success at attracting chipmakers and data centers may even have come as a slight surprise. Today, officials are furiously updating their industrial and energy roadmaps. Without a quick reaction, the next surprise could be energy shortages.
Chips ahoy
A leading producer and innovator of semiconductor chips in the second half of the 20th century, Japan’s influence in the sector waned significantly in the 1990s. As a result, many of its facilities shuttered or curtailed output.
Major players, such as Toshiba, which invented flash memory, sold chip-related assets or exited the business. Toshiba Memory was sold in 2018 to private equity firm Bain Capital to help its parent firm survive severe financial straits. The Bain-controlled entity is now known as Kioxia, with Toshiba Corp remaining a minority shareholder.
The fortunes of Japan’s semiconductor manufacturers have turned around in recent years as the geopolitical tensions between the U.S. and China favored a shifting of supply chains to allied territories. As well as tempting industry-leader TSMC to open its first ever fab in Japan, METI has engineered the creation of a new semiconductor champion in the country – Rapidus Corp.
Rapidus has set an extremely ambitious target of catching up with leading global chip makers in a matter of a few years. The company started construction of its first fabrication plant in Hokkaido last year, and hopes to launch a pilot manufacturing line in 2025. Mass production is due to follow a year or two later.
These are not the only semiconductor facilities in the works. TSMC has already announced plans for a second factory in Kyushu, at the same location as its first, and is mulling a third. A rival chip-maker from Taiwan, PSMC, has joined with Japanese conglomerate SBI to build a fab in Miyagi Pref. Kioxia, the former Toshiba unit, has two new manufacturing expansion projects. And there are at least a dozen other new factories planned in Japan for various kinds of chips.

Of course, a semiconductor fab does not exist by itself; manufacture is reliant on at least two dozen or so suppliers of materials, components, equipment, and post-processing, the capacities for which also need to increase in Japan.

How much energy does a chip need?
In 2025, at the stage of a pilot manufacturing line, the Rapidus semiconductor fab in Hokkaido will need access to about 100 MW of capacity, according to the firm’s own estimates. Once it ramps up to mass production, full capacity needs might escalate to 600 MW. That’s more electricity generation capacity than either of the first two units of the Tomari Nuclear Power Plant in Hokkaido, which has been offline and under inspection by the nuclear regulator for over a decade.
What’s more, Rapidus management vowed to procure all their electricity from clean energy sources, since their clients are likely to be major IT firms with net-zero commitments. This allows Rapidus to procure from renewable energy sources or nuclear. At present, Tomari NPP isn’t available. But even if its 912 MW Unit 3 is finally allowed to restart, local power demand won’t be sated.
Near the Rapidus fab will operate various suppliers as part of a planned semiconductor cluster. How much power they’ll require in total is still unclear, but according to U.S. experts, every $1 billion spent on new chip manufacturing leads to about $300 million in primary electricity purchases. That expenditure ratio doubles with data centers, said Mark P. Mills, the executive Director of the National Center for Energy Analytics, in recent testimony to the U.S. Senate.
In Kyushu, TSMC has not yet publicly articulated its energy demand, but its new semiconductor plant in Arizona, U.S. will require 200 MW at the first phase and then 1 GW at full capacity, the CSIS think-tank said last month, citing filings for the local transmission system expansion. The Taiwanese company used about 21 TWh of electricity in 2022. That’s equivalent to about 2.4% of Japan’s national total, or 40% of the volume generated by nuclear plants in FY2022.
Moving the needle, already?
TSMC’s first factory in Japan has operated for only a couple of months, so it’s too early to make definitive conclusions. However, several trends are already visible, according to data provided to Japan NRG by energy forecasting specialist, Yes Energy.
On a national level, YoY electricity demand has been 0 or negative between March 2022 and March 2024. This is based on Yes Energy data that filters out weather impact on power demand; the data covers all the major grids in Japan apart from Okinawa. In March 2024, the demand was up 1.9% on a year earlier; in April, it was 0.1%.
Once we zoom into the electricity demand picture in the Kyushu region, however, things are even more stark. Kyushu’s YoY demand growth turned positive in September 2023. While that particular month’s consumption is ‘artificially’ inflated because of the power outages in Sept 2022 due to Typhoon Nanmadol, the rest of fall and winter 2023/24 shows positive weather-corrected demand growth even as nationwide figures are negative.
The leadup to the TSMC factory opening is a possible contributing factor, according to Mark Todoroff, business development director at Yes Energy. The demand switch starts to be seen after the August Obon holidays and continues into 2024, apart from two weeks in early January.

Judging by the rollout of new semiconductor facilities nationwide, similar changes are coming to Hokkaido, Tohoku, and some parts of Kansai.
The nation’s energy planners thought this decade would be dedicated to replacing fossil fuels in a shrinking electricity system. Now they’ll need to consider how to shift to cleaner sources in an expanding market.
BY JOHN VAROLI
This weekly column focuses on energy events in Asia and the Pacific
Australia / LNG
Shell expects that its Australian supplies of LNG will help meet demand from emerging markets in south and SE Asia. Philippines, Thailand, Vietnam and Bangladesh are expected to be key growth markets.
Australia / Nuclear power
The cost of nuclear power is six times higher than renewable energy, making it the most expensive energy source in Australia, according to the Clean Energy Council, adding that nuclear power stations are expensive and must run non-stop to break even.
BESS
Battery energy storage systems (BESS) are projected to be the most competitive power storage type because of the sharp decline in its cost due to innovation in technology and manufacturing. BMI reported that since 2010, the average installation costs dropped by 90%, making its price lower than pumped-hydro storage.
China / Oil and gas
Sinopec and TotalEnergies signed a strategic cooperation agreement to cover oil and gas development, LNG value chain, refining and chemicals, engineering and trading, and new energy.
China / Hydropower
A report by Cornell University claims that China’s decarbonization plan could negatively impact crucial river systems and farmland, especially due to hydropower expansion in the Mekong and Salween basins. Potential problems include river fragmentation and altered flood cycles.
LNG
Last week, Asian spot LNG prices rose to the highest levels since January; hot weather spurred demand for the fuel. In May, Asia remained the preferred destination for U.S. free-on-board LNG, with India, Japan, and South Korea resuming their buying.
South Korea / Hydrogen power
The country launched the world’s first auction for clean-hydrogen-fired power, for up to 6,500 GWh of electricity produced annually over a 15-year period, starting 2028. The 15-year contracts are for 100% H2-based electricity generation (using turbines or fuel cells), ammonia co-fired in coal power plants, or hydrogen co-fired at natural gas power plants.
Taiwan / Offshore wind
Copenhagen Infrastructure Partners (CIP) completed construction of the 600 MW Changfang-Xidao offshore wind project. It comprises 62 Vestas V174 turbines.
Thailand / SMRs
Thailand’s EGAT and EDF (France) discussed collaboration on developing Small Modular Reactor (SMR) technology. The goal is to diversify clean electricity production options, supporting Thailand’s carbon neutrality goals.
Vietnam / Renewable energy
Việt Nam Electricity reported that, to date, 29 renewable energy projects with a total capacity of more than 1.58 GW have been supplying energy to the national power grid.
