NEWS: GENERAL POLICY AND TRENDS

NEWS: GENERAL POLICY AND TRENDS

Govt experts consider data center sites based on proximity to clean power

(Government statement, April 15)

  • The Cabinet Secretariat set up a working group to discuss measures to implement the GX industry location policy, including attracting investment to regions with abundant decarbonized energy and promoting the new GX-type industries.
  • The discussion will help identify locations suitable for high-energy-consuming facilities, such as data centers, and seek to align the discussions with that of the Watt-Bit Council, a new public-private dialogue addressing a similar issue.
  • The working group, chaired by Ohashi Hiroshi, VP of the University of Tokyo, will formulate policies by summer 2025. The focus will be:
    • Identifying conditions to promote industrial clustering near decarbonized power sources and reduce energy price gaps with other countries;
    • Consider measures such as targeted financing, regulatory reforms, and investment incentives; 
    • Address a shortage of industrial land that is estimated to be at half the level of 1996 and the mismatch between supply and demand across prefectures;
    • Benchmark international practices, such as France’s approach to data center location planning, which involves govt designation of 35 areas close to nuclear power plants to support the AI-driven national strategy;
    • Attract foreign investment by assessing Japan’s competitive advantages.
  • CONTEXT: The GX 2040 Vision formulated in February emphasizes the need to accelerate the clustering of industries with a view to utilize decarbonized power sources in terms of GX industrial location. Supply is needed to cover the vast amount of electricity consumed by AI data centers.

TAKEAWAY: Japan is exploring a similar strategic site-selection method as France, and may designate certain zones as favorable for new data centers based on the availability and proximity of nuclear and renewable energy. This is reminiscent of the Special Economic Zones approach of PM Abe’s govt in the early part of the previous decade.

NEWS: ELECTRICITY MARKETS

TOCOM power futures trading hits record high in March 2025

(Exchange statement, April 9)

  • Power futures trading on the Tokyo Commodity Exchange (TOCOM) surged to a record 12,600 contracts in March, over 2.5 times higher than the previous peak of 4,853 contracts in May 2022.
  • A single day’s trading volume on March 13 reached a historic high of 711 GWh, significantly surpassing the prior daily record of 153 GWh on Nov 7, 2024.
  • Off-floor transactions dominated activity, accounting for 154 of the total 167 trades. On March 13, annual baseload contracts for the East accounted for 9,720 contracts.
  • Smaller-scale futures trades also increased, suggesting growing participation among new power retailers, with trades as small as one contract per month observed.
  • CONTEXT: Q1 was particularly strong. February’s trading volumes were 205.7 GWh, a 2.3-fold increase from the previous month. Among the drivers was a concern about the wholesale power price for West Japan.
  • SIDE DEVELOPMENT:
    Spot electricity prices drop in March as supply eases
    (Exchange statement, March 2025)
    • Spot electricity prices (JEPX) declined across all 9 regions in March over February, driven by mild temperatures, easing heating demand, though volatility rose due to periodic cold snaps and scheduled maintenance outages at thermal plants.
    • The monthly average temperature nationwide was 1.13°C above the 30-year average, the seventh highest March since records began in 1898.
    • Fuel prices diverged: Crude oil rose ¥2,443/ kl to ¥78,186; coal declined ¥1,689/ ton to ¥21,692; and LNG fell significantly by ¥6,061/ ton to ¥94,310, influenced by geopolitical risks and U.S. tariff policies.

TAKEAWAY: The JEPX wholesale power exchange just had its 20-year anniversary, and market volumes are up over 300-fold since its start. Quite a large part was due to regulatory changes. In March 2013, major power utilities (EPCOs) were mandated to bid on the spot market, and full liberalization of retail electricity sales launched in April 2016, expanding the buyer base. As the interconnector gate capacities expand, there is also more cross-regional electricity trade and more price correlation between markets.

EGC discusses reflecting inflation in revenue cap system

(Government statement, April 15)

  • At an EGC expert meeting, the Transmission and Distribution Grid Council and TSOs called to adjust the revenue cap system to reflect rising labor costs and inflation. 
  • Currently, the cap does not allow for inflation-based cost increases, thus requiring companies to absorb rising expenses.
  • Experts agreed that such adjustments should be made in the second regulatory period (FY2028-FY2032). Some argued it should also apply retroactively to the first period (FY2023-FY2027), since the cost impact has already been significant, estimated at ¥150 billion in FY2023 alone.
  • The EGC will continue to discuss the factors contributing to price increases, as well as the differences in the numbers reported by each operator, and further standardization and refinement of the calculation methodologies.
  • CONTEXT: The T&D network usage charge, known as the “wheeling charge,” was previously calculated using the “total cost method”. But from FY2023 it’s calculated using the “revenue cap system”. Operators prepare five-year business plans, and the govt reviews the costs necessary to implement these plans (revenue cap).

Hitachi Energy selected for HVDC to deliver 6 GW of renewables in India

(Company statement, April 3) 

  • Hitachi Energy won a contract to build a 950 km, 6 GW HVDC transmission link in India. The firm formed a consortium with state-owned Bharat Heavy Electricals, a major engineering and manufacturing firm.

Japanese Firms Expand SE Asia LNG Projects as Region Shifts to Gas

Japan’s top utilities and energy companies are accelerating their LNG push into Asia as they seek to capitalize on new markets for the fuel. Southeast Asia is of particular interest and a key component of METI’s 2020 international energy strategy.

As of today, Japanese firms including JERA, Tokyo Gas, and KEPCO are active in about 30 projects across Asia-Pacific that span the entire value chain, from distribution infrastructure and regasification terminals, to gas-fired power plants. The proposed generation capacity of projects with Japanese involvement has climbed to about 60 GW.

The context is that Japan faces an oversupply of LNG in the coming years and needs to build ‘secondary’ markets to sell its surplus. Long-term offtake agreements with Australia, Qatar, Malaysia, and the U.S. helps to protect Japan’s security of supply but also lock buyers into volumes that the domestic market seems no longer able to absorb. Should METI’s own 2040 national energy mix forecasts materialize, demand will wane further.

Despite softening domestic demand, the government sees it as imperative to defend Japan’s position as one of the top players in the LNG sector. That means finely balancing new investment in supply and the demand side within an industry often susceptible to economic and political changes.

Japan NRG takes a look at the significant LNG-related projects with Japanese involvement in Southeast Asia, as well as at the region’s overall outlook in this sector.

JERA and Tokyo Gas

As Japan’s major LNG traders, JERA and Tokyo Gas are leading related infrastructure expansion in Asia. JERA has set a goal of introducing LNG to Asia’s coal-and-oil reliant countries, while Tokyo Gas seeks to develop a specifically South-Asian LNG chain.

The driver is straightforward: Japan wants to diversify its LNG supply sources to improve energy security. This necessitates creating new overseas markets for the fuel in places like Vietnam, Indonesia, and the Philippines. With more Asian nations turning to LNG, Japanese firms can play the role of re-seller, or trader of the fuel. And, if Japan suddenly runs short, there would in theory be more LNG cargoes in the region to buy or swap.

Source: Tokyo Gas

Of course, the opportunities for Japanese players are not limited to trading the molecules.

In February 2025, Tokyo Gas made its first investment in an operational overseas LNG terminal. It acquired a 20% stake in FGEN LNG Corp, which owns and operates a floating LNG terminal in Batangas City in the Philippines. Tokyo Gas said it will support the facility’s operations and maintenance, leveraging its experience of managing LNG terminals in Japan.

Further downstream, Tokyo Gas is involved in a LNG-to-power project in Thai Binh Province, Vietnam, that includes a 1.5 GW gas-fired power plant and an offshore LNG receiving terminal. The 2024 investment partners the Japanese gas utility with Truong Thanh Viet Nam (TTVN) and an overseas unit of Kyushu Electric – Kyuden International Corp. The goal is to start power operations by 2029.

The above has built on another Vietnamese LNG-to-power project Tokyo Gas launched in 2022. The $2 billion project involves bringing gas-fired power to the Quang Ninh Province, with operations slated for the latter half of the 2020s.

The arrival of gas-fired power and LNG imports to Southeast Asia is a recent phenomenon.

The Philippines and Vietnam only began importing LNG in 2023, as did Hong Kong. The first LNG cargoes reached Cambodia and Myanmar just a few years before that.

Population and economic growth, however, are pushing a very steep demand trajectory.  Petrovietnam’s PV Gas estimates that the nation’s LNG imports will reach 9 million tons per annum (MTPA) by 2030 and 15 MTPA by 2035, for a total value of $7.2 billion. Despite this, Vietnam has not secured any long-term LNG contracts; the same for the Philippines.

Source: Tokyo Gas

This means Japanese firms are not only playing the role of LNG sellers – they are helping to prepare the institutional and logistical networks for Southeast Asia to lean into the fuel. In December 2023, JERA signed an MoU to assist with the introduction of LNG in the Philippines. For value chain development, JERA also signed an MoU with a subsidiary of Indonesia’s state-owned electricity company PLN for collaboration.

Previously, JERA proposed a 4.5 GW LNG-fired power plant and import terminal with ExxonMobil in Vietnam. Should it go ahead, that project alone would require imports of about 6 MTPA. Such volumes would complement JERA’s sales in its domestic market and allow it to redirect LNG vessels to balance surpluses / shortages in Japan.

The origin of much of this LNG is likely to be Australia and the U.S. JERA sees U.S. LNG as an attractive option: there is abundant supply, relatively low costs, and now with Trump in the White House – strong support from the government. At the very least, this indicates that U.S. projects would get faster approval for construction and exports compared to Australia.

Flexible contract terms in the U.S. market are another big selling point for Japanese firms like JERA that have ambitions to trade LNG in the Asia region. JERA is leveraging the flexibility of American contracts to push Australian suppliers to do the same.

Asia’s LNG landscape

Global LNG demand is expected to grow to 630-718 MTPA by 2040, up from the 407 MTPA in 2024, with Asia the main driver behind this 60% growth, according to Shell. By 2030, Shell forecasted a growth of 170 MTPA.

Analysts at the environmental think-tank IEEFA are more circumspect. Such a boom in LNG implies a shift away from coal and no serious competitive threat from other energy sources. Meanwhile, coal’s share of the energy mix hit a record (62%) in Indonesia in 2023 – similar to levels in the Philippines. Plus, the average age of coal-fired power plants was just 11 years when the IEA last reported the data in 2021.

Another issue is the slow progress of many Southeast Asia LNG projects, primarily in terms of contracting and negotiation. For example, Tokyo Gas and Pertamina in 2015 worked on an LNG terminal in Indonesia, but it was deferred due to uncertain demand.

What’s more, Japan is not the only LNG powerhouse in Asia anymore. Looking at the Asian market, there are at least two major competitors to Japan’s LNG export strategy: China and Singapore. China has overtaken Japan as the world’s largest LNG importer, and with its U.S.-origin cargoes now under the cloud of tariffs, Chinese trading volumes are rising.

Still, Japan’s state energy firm JOGMEC believes that Tokyo’s strategy has every chance of success. When asked by Japan NRG, JOGMEC noted that while Chinese imports this year are at the lowest levels since 2019, intensified LNG trading activity by China and Japan is likely to be complementary. The two can inject liquidity and volumes in the Asian market, supporting the trend rather than directly competing with each other.

Singapore is also positioning itself as a major LNG trading hub thanks to its hosting of many financial institutions, oil companies, and trading platforms. Most of the Japanese firms have also opened LNG trading desks in the city.

Japan cannot compete with the financial infrastructure of Singapore but it has made a start. The Tokyo Commodity Exchange, for example, launched yen-denominated LNG futures in 2022, though growth in trading volumes has been slow. Expanding this market will be crucial to Japan’s ability to hedge against price fluctuations.

Conclusion

For Japanese firms, securing a foothold in Southeast Asia by participating in infrastructure projects allows them to retain leverage in price negotiations. The LNG market is projected to expand in the region, and Japan’s industry veterans smell a business opportunity.

Still, Japan claims that its LNG strategy is not only about economic advantage, but also a matter of energy security. As the country looks to buy more LNG from the U.S., so as to appease the Trump administration, the plan of reselling LNG to Asian countries gains further strategic significance amid shrinking domestic demand.

Through recent initiatives such as the Asia Zero Emission Community (AZEC), Japan has laid the political groundwork to promote LNG as a critical bridge fuel in the transition to a lower-carbon future. For this, critics accuse Japan of locking Asia into another fossil fuel.

Yet with few other actors coming into the region to finance major shifts to other energy sources, Japan’s offer may be the most pragmatic on the table.

What’s That Smell? E-Methane Pitches an
Alternative to the Hydrogen Society

Japan has created artificial islands using landfill waste. One such plot in Tokyo Bay even has the cheerful name “Dream Island.” Now, the country is putting waste to use in a supply chain that offers a cleaner alternative to fossil fuels.

Last year, a demonstration project in Osaka City, currently host to the World Expo, utilized raw garbage and renewable energy to produce e-methane, a synthetic gas that promises to recycle CO2 without adding to the global carbon footprint, all while utilizing existing gas infrastructure. A similar pilot is in operation just south of Tokyo, in the city of Yokohama. And while small, the tests indicate the potential for mass scale production already by the end of this decade.

Capturing the gases emitted from burning waste is just one of the pathways Japan is trialing to form the outline of a next-generation, low-carbon gas system. While electrification is expected to shift some of the energy demand from molecules to electrons, the country is still one of the top importers of natural gas via LNG. Almost half of those volumes are deployed in heating and industrial equipment – areas that are harder to electrify and abate. That suggests a substantial market for cleaner gas substitutes.

Traditionally, the process of methanation involves synthesizing methane from hydrogen and CO2. The latter is recovered from the atmosphere or industrial emissions. When the hydrogen is made with renewable energy, the end-product is called e-methane. Like the liquid synthetic fuels (e-fuels), e-methane is touted as the future lynchpin of energy systems because it does not increase atmospheric CO2 levels over its lifecycle and has higher heating value per unit than hydrogen or ammonia when combusted.

One of the biggest stumbling blocks to creating an energy system based on synthetic fuels like e-methane, however, has been the cost of producing hydrogen (H2). This is why Japan has started testing several ways to make e-methane, some of which do not require H2 as a feedstock.

Current gas needs

In Japan, the majority of natural gas is imported as LNG, and the consumption ratio (in FY2022) was 54% for electricity, 35% for city gas, and 10% for other uses. The breakdown of city gas use by sector was 59% for industrial, 23% for residential, and 10% for commercial.

Industrial use is primarily as a fuel for heat source equipment, such as steam boilers and furnaces, and as a fuel for power generation. Residential and commercial use is primarily for heat source equipment such as kitchens, water heaters, and space heaters.

To reduce GHG emissions, various firms have developed gas turbines and boilers, etc that can switch to hydrogen or ammonia, and some electrified options are also starting to appear. Still, in cases where there’s a need for high temperatures and/or large equipment, retaining existing gas-based supply chains and infrastructure but switching to a cleaner fuel is seen as ideal.

R&D Trends in e-Methane

Methanation methods can be broadly divided into chemical and biological reactions. The former relies on the Sabatier reaction (CO2 + 4 H2 → CH4 + 2 H2O) with a catalyst, but the scale of the output needs to be grown. Much of Japan’s R&D in this area is focused on finding more efficient synthesis through discovering better catalysts. 

Methanation using biological reactions (bio-methanation) swaps the catalyst for methane-producing bacteria. However, its scale at this point is even smaller than for a chemical reaction.

Pilot projects

E-methane as a clean energy solution has drawn interest from numerous sectors including shippers, heavy duty transportation (i.e., trucks and buses), high-temperature industrial processes (steel, cement, and ceramics), as well as the chemical industry.

The main companies driving the development of e-methane in Japan, however, are the two large gas utilities from Tokyo and Osaka, the oil and LNG producer INPEX, and the top engineering group, Mitsubishi Heavy Industries (MHI).

Tokyo Gas started small-scale methanation tests in 2021, which progressed into a pilot project that pools together several players into a fully contained local supply chain. Thanks to an agreement with Yokohama City in 2022, MHI installed a system to capture flue gas at a municipal waste-to-energy facility (Tsurumi Plant) that is then transported to the Tokyo Gas Yokohama Techno Station for methanation using the Sabatier method.

The pilot operates at a rate of 400-500 Nm3 of e-methane per hour. In the 2030s when the technology is deemed mature, this is expected to ramp up to tens of thousands of Nm3/ h.

Assuming a methanation facility with a nameplate capacity of 10,000 Nm3 is able to run nonstop year-round, its annual output would be close to 88 million Nm3. This would help Tokyo Gas get close to its requirement of substituting 1% of city gas sales with e-methane by 2030, as per the national target. (Based on a m3 to Nm3 conversion that assumes the gas is transported at near atmospheric pressure and at standard temperature.)

Osaka Gas and INPEX have a similar scale Sabatier methanation project (400 Nm3/ h) that aims to use the synthetic fuel in the local gas pipeline system. Gas extracted from one of Japan’s largest gas fields, in Nagaoka, Niigata Pref, will be sent to a methanation facility due to be commissioned this (FY2025) fiscal year.

Source: INPEX

To spread public awareness of methanation as a future clean energy pathway, Osaka Gas has also created a small-scale pilot to coincide with the World Expo, which kicked off April 13 in the company’s home city. 

The project is deploying the Sabatier method to extract biogas from household waste (CH4), supplement it with CO2 collected through Direct Air Capture, and bind it to hydrogen made with renewable energy. Kanadevia supplied the methanation equipment.

Other approaches

The Green Innovation Fund has seeded a number of projects to develop other methanation methods, such as a “hybrid Sabatier” approach, which relies on PEM electrolyzers (the “PEMCO2 Reduction” system), and new technologies that work at low temperatures.

The hybrid Sabatier process claims not only to improve efficiency (from 50% to 80%) by more effectively utilizing waste heat from electrolysis (an endothermic reaction), but also promises to make devices smaller and at a lower cost. Among potential future demand centers is Japan’s space agency. JAXA and MHI are developing a liquid methane-fueled engine for a next-generation rocket that is expected to take off around 2030.

Electrochemical reduction (PEMCO2) is a technology that reacts at low temperatures (about 80°C), eliminating the need for thermal management, which is a problem with the Sabatier reaction. PEMCO2 is also a much simpler industrial structure, making it cheaper. The main proponent of this approach is MHI’s domestic rival IHI Corp, which sees this tech as capable of manufacturing from tens to several hundred Nm3/ h by FY2030.

The most interesting approach, however, may be pursued by Osaka Gas. The west Japan utility is backing the development of bio-methanation and Solid Oxide Electrolysis Cell (SOEC) – this methanation process uses Solid Oxide Fuel Cell (SOFC) technology. First, water and CO2 are electrolyzed using an SOEC electrolyzer to produce H2 and CO using renewable energy. Next, methane is synthesized from these in a catalytic reaction. Not requiring hydrogen as a raw material is a key feature.

In addition, electrolysis at high temperatures (around 700-800°C) reduces the amount of renewable energy required. By effectively utilizing the heat generated during methane synthesis, it is possible to achieve a world-leading energy conversion efficiency of 85-90%. The result could significantly reduce the cost of producing e-methane.

Together with the National Institute of Advanced Industrial Science and Technology, Osaka Gas hopes to develop SOEC methanation-related technologies into a unified supply chain by 2030.

International cooperation

The domestic projects offer glimmers of technological progress, but for volume, Japanese companies are looking elsewhere. A Japan-U.S. consortium including Tokyo Gas, Toho Gas, Mitsubishi Corp and Sempra Infrastructure is promoting the ReaCH4 Project on the Gulf Coast of the U.S.

The aim is to build the world’s first large-scale e-methane supply chain that will be capable of producing 180 million Nm3 of e-methane (close to 130,000 tons) in FY2030. Sempra refers to e-methane as e-natural gas and intends to use its Cameron LNG terminal in southwest Louisiana for liquefaction of the gas before its transport to Japan.

In November 2023, Tokyo Gas and Santos announced plans to conduct a feasibility study on a project to produce e-methane in the Cooper Basin in central eastern Australia. The Australian energy firm has developed gas fields in the area for decades. The project aims to export 60,000 tons of e-methane per year (equivalent to 80 million m3 of city gas) to Japan from 2030, with a view to scaling that up even further.

Osaka Gas is conducting feasibility studies across several regions but especially in America, Australia and Southeast Asia, looking to build on existing natural gas and LNG facilities. The utility is keen on establishing an e-methane hub in either Nebraska or western Wyoming where it can source cheap hydrogen, and then send the product by pipeline to Texas to ship to Japan.

The utility is ready to invest as much as ¥100 billion in the U.S. e-methane projects and wants to import as much as 200,000 tons of the synthetic fuel by 2030. Work on basic project design started earlier this year.

To build the sector’s visibility, in October 2024, Japanese firms founded an international alliance called e-NG Coalition to pool together firms that promote e-methane (aka e-natural gas). They want to create a global market by standardizing GHG emission calculation and certification standards.

The nine founding companies were Tokyo Gas, Osaka Gas, Toho Gas, Mitsubishi Corp, Engie, RWE, Sempra Infrastructure, Tree Energy Solutions Belgium (TES) and Totalenergies. Since then, the membership has increased to 20 with IHI and INPEX among the new faces.

How to pay for this?

As with e-fuel, the biggest issue for e-methane is reducing production costs, which are typically five times that of LNG. According to some producer’s calculations, the cost of synthetic methane (CIF price) is currently ¥250/ Nm3 using the Sabatier method. The plan is to reduce this to about ¥120/ Nm3 by FY2030, and to ¥50/ Nm3 by FY2050 through better technology and lower hydrogen feedstock.

Even that price trajectory requires additional fees. For now, Japan is considering a number of approaches to cover the price gaps including some form of an e-methane marketplace, or by further expanding quotas from the current 1% by 2030.

The latter would still require a way for the buyers to pass on the higher costs compared to LNG. These may be addressed either through a contract for difference (CfD) support scheme, as already initiated late last year on the back of the Hydrogen Society Promotion Act. Another alternative is the gas wheeling charges system.

It’s likely that several of the above will need to be put into place within the next three years or so to enable e-methane to gain a foothold in Japan’s energy system. The results of this year’s CfD – which allows the subsidies to cover e-methane – may be the first indication of which way the sector will develop commercially.

ASIA ENERGY REVIEW

BY JOHN VAROLI

A brief overview of the region’s main energy events from the past week

Australia / Renewables

ACEN Australia completed its AU$750 million portfolio debt financing to support renewable energy expansion. The financing will support the 400 MW Stubbo Solar project in New South Wales.

Australia / Solar power

Octopus Australia will soon start construction on the AU$300 million Fulham Solar Farm. The project will have an 80 MW solar farm and a 128-MWh battery project. 

China / Coal

Coal production set a new monthly record of 441 Mt in March, as the country focuses on increasing domestic output and reducing reliance on imports. Coal production has totalled 1,203 Mt so far this year, up from 1,106 Mt in the same period in 2024, and surpassing the previous record of 1,153 Mt in 2023.

Data Centers/ Electricity demand

Electricity demand from data centers worldwide is projected to more than double by 2030 to around 945 TWh, said the International Energy Agency. Electricity demand from AI-optimized data centers alone will more than quadruple by 2030.

India / Hydro power

The Central Electricity Authority approved six hydro projects – Upper Indravati (600 MW) in Odisha; Sharavathy (2 GW) in Karnataka; Bhivpuri (1 GW) in Maharashtra; Bhavali (1.5 GW) in Maharashtra; MP-30 (1.9 GW) in Madhya Pradesh; and Chitravathi (500 MW) in Andhra Pradesh.

India / LPG

India plans to end taxes on U.S. ethane and liquefied petroleum gas (LPG) imports as it looks to reduce its trade surplus and ease its tariff burden.

India / Renewables

India continues to expand renewable energy capacity, installing nearly 30 GW of solar and wind power in FY2025. According to JMK Research, compared to 2024, installations for both solar and wind increased 58.5% to 23.8 GW and 27.9% to 4.1 GW, respectively.

Indonesia / LPG

Indonesia proposed increasing imports of crude oil and LPG from the U.S. by $10 billion as part of tariff negotiations, said energy minister Bahlil Lahadalia.

Singapore / Power grid

Singapore is stepping up efforts to strengthen its power grid and diversify energy sources, with natural gas — currently powering 95% of the country’s electricity — still playing a major role. As the city-state targets GHG emissions of 45 Mt to 50 Mt by 2035, authorities face the dual challenge of meeting rising energy demand while decarbonising the grid.

Vietnam / Power plan

The latest amendments to the Power Development Plan, approved by the govt earlier this week, call for the nation to more than double total generating capacity by 2030 over 2023 levels, with the aim of increasing capacity nearly 10-fold by 2050. Solar and wind power will be key. To meet these targets, Vietnam needs a total investment of $136 billion by 2030.
