AOMORI PROPOSES NEW REGIONAL RULES FOR ‘COHABITATION’ WITH RENEWABLES PROJECTS
Last year, Aomori Prefecture’s incoming governor announced an audacious plan for a regional tax on renewable energy projects, calling for a levy that would apply even to existing solar and wind farms. A year on, the prefecture’s strategy for the renewables sector looks quite different. This month, the prefecture’s expert panel published a skeleton draft of an ordinance that would see local authorities assume greater control over solar and onshore wind projects.

TAKEAWAY: As global prices for fuels cooled after the 2022 energy crisis, the govt stopped subsidies for power and gas in May of this year. However, the weak yen raises the cost of importing fuels; meanwhile, PM Kishida is facing his lowest popularity since taking on the job. The ruling Liberal Democratic Party will hold its next leadership contest in September. Kishida, however, has presented the latest energy subsidies in a different light, claiming they are related to severe weather (as opposed to global fuel prices). In June, he said that this would be “emergency support to survive the extreme heat.”

PART ONE: Building Hydrogen/ Ammonia Supply Chains –
How Far Have They Come?
After Japan’s government published the Basic Hydrogen Strategy in 2017, over 50 supply chain plans sprang up from business consortiums and municipalities. Now, new feasibility study launches are continuing into this year.
The Hydrogen Society Promotion Act that passed the Diet in May promises subsidies for 15 years for qualified projects. Many studies and projects in Japan are about building supply chains, rather than a large production base.
The new sources of clean energy need to satisfy the “S+3E” criteria to get state funding. It stands for “safety, economic efficiency, energy security and environment-focused”. This means that supply plans need to address consumer demand, which is about delivering hydrogen in an economically efficient manner. Hydrogen user hubs need to identify their sources of stable supplies.
Green hydrogen production sites will go onstream in 2025, and the next wave of hydrogen market hype will be about 2027, when ammonia-coal co-firing begins. In the 2030’s, hydrogen-fired power generation and other technologies under development are expected to fully enter the market.
This analysis is Part 1 of two articles, and it looks into the projects in an advanced phase. Naturally, the smaller ones are commercializing first.
Repurposing oil infrastructure
METI has clearly stated that supply chain building makes the national economy stronger. Companies with a total supply chain system will be more likely to compete in international markets compared to those with solutions that address only part of the supply network.
Japan NRG categorized these supply chain projects into three types:
The re-use of legacy infrastructure has both cost and lead time advantages. It’s cheaper to upgrade naphtha pipelines to accommodate high-pressure gas, rather than building a whole new transportation network. Commercial hydrogen supply services are already operational in Kawasaki City using decades-old plastic waste treatment facilities and pipelines.
Since 2003, chemical manufacturer Resonac has been producing hydrogen from plastic waste. Its Kawasaki plant produces about 20,000 tons/ year of hydrogen. “In the early days, plastic recycling was unpopular because people thought the process was polluting, but after Coca Cola called it a climate solution, the momentum picked up,” said a Resonac official.
Today, the use of plastic waste-derived hydrogen can boost corporate image. The Kawasaki King Skyfront Tokyu Rei Hotel, located several kilometers away from the Resonac plant, switched to hydrogen-fueled heating and power systems two years ago. After almost a year of trial runs at the hotel, Resonac decided to commercialize its hydrogen supply service. Since last September, it has been delivering the gas via underground pipelines built for naphtha. In addition to hydrogen, Resonac produces ammonia.
ENEOS is another upcycler, developing a value chain centered on the methylcyclohexane (MCH) chemical compound. After reacting with toluene, hydrogen converts into MCH, making it possible to store and transport it at normal temperatures and pressures.
This is unusual for the hydrogen family, which requires temperatures below zero and high pressure for storage. Thanks to MCH, conventional tankers, trolley trucks, onshore and offshore oil tanks, and oil refineries can be used. Refineries have dehydrogenation equipment that converts MCH back to hydrogen.
ENEOS plans to import thousands of tons of MCH through the Kawasaki port, supplying it to Haneda Airport and others along Tokyo Bay. Last year, it held the first MCH value chain trial run: Hydrogen produced and converted to MCH in Australia, using its proprietary technology called DirectMCH, was shipped to Japan, where it was converted back to hydrogen at a refinery and finally used to fuel a fuel-cell-vehicle. The ship carried only a few tons, but a second trial run is planned for 2025. This time, the volume should be larger as ENEOS is scaling up its 150 kW Australian electrolyzer to a 1-MW size or larger.
The MCH chain will commercialize in about 2030 when there are more hydrogen supplies overseas. ENEOS also has issues to clear before the service launch. In order to carry more MCH, it seeks to change a regulation on the tanker cargo volume limit, which stands at 3,000 cubic meters for Class 2 tankers.
The consumer side of the supply chain also needs to be strengthened. ENEOS wants to find more users like Haneda Airport that plans to introduce a hydrogen-fueled system to supply power and heat to the terminal building.
Repurposing could take longer if the old and new functional requirements are too different. A consortium in west Japan plans to install gas pipelines in the ducts along the railway tracks and underground telecom cabling systems, to deliver to industrial users hydrogen imported into the port of Himeji.
Fusion of flammable gas and telecom cable pipelines is unprecedented, and it may take years to reset safety and other requirements as these are essential infrastructure. The consortium in charge, which consists of Kansai Electric, the NTT Group, the JR Group and Panasonic, has a vague target for commercialization. They say the project will be operational in the 2030’s.

Railway and communication cable network (Hyogo Pref) | Kansai Electric, JR Group, NTT Group, Panasonic | Using telecom and railway network to transport hydrogen to industrial users | Field studies in 2024-2025; Commercial rollout in 2030’s |
Ammonia supply chains to serve big users
Coal-ammonia co-firing, or mixing ammonia with coal, to generate power is a typical demand-driven project. It involves a handful of users with a significant demand, and the supply chains are custom-tailored for them. Co-firing is also a repurposing of existing infrastructure. The power plants are not overhauled entirely, but burners and related equipment are replaced.
Therefore, the lead time for building co-firing supply chains is relatively short: from planning to full-scale operation would take six years. Domestic supply chains are possibly the shortest in terms of distance: only a few kilometers from certain ammonia port terminals to the power plants.
The major ammonia supply chain projects are: the Central Japan Hydrogen and Ammonia project in Aichi, Mie and Gifu prefectures; and the Shunan Industrial Complex project in Yamaguchi Prefecture. The consortium running these projects have strong support from the municipal and national governments, which also helped shorten the lead time.
The government has an ammonia first policy. The Ministry of Land, Infrastructure, Transport and Tourism (MLIT) is writing ammonia bunkering guidelines although there’s no ammonia oceangoing vessel sailing anywhere. Thanks to this push, the ammonia supply chains are likely to launch in 2027-2028, before ENEOS brings onstream its MCH chain.
JERA, the key player in the Central Japan consortium, will start running the Hekinan No. 4 coal power unit with 20% ammonia co-firing in FY2027. It recently completed a three-month co-firing trial at Hekinan and will start plant reconstruction later this year.
During the trial, co-firing was not conducted continuously at 20%, with time spent on testing and measuring emissions as well as power generating performance. Preparing for the FY2027 start of commercial-scale, continuous co-firing will involve not only building the new infrastructure, such as bigger ammonia storage tanks, but also thorough equipment checks.
Tokuyama, Tosoh and Zeon Corp, which operate coal power plants in Shunan, plan to start ammonia co-firing in 2028 and later. But they have not conducted any trials yet. Meanwhile, JERA has already held international tenders to purchase ammonia, and selected the initial suppliers, which will deliver the fuel to the Kinuura port, now a coal offloading terminal. For the Shunan users, Idemitsu Kosan will be the supplier of imported ammonia.
In terms of volumes, JERA will require at least 0.5 million tons/ year, while the three Shunan companies will need about 1 million tons/ year combined.
Ammonia is also used to replace methane and other gases used at chemical plants; the gases fuel naphtha crackers. Idemitsu Kosan has succeeded in running a naphtha cracker with ammonia replacing 20% of the fuel. Mitsui Chemicals, which is building an ammonia supply chain based in Osaka Bay, aims for an even higher ammonia ratio. In fact, it seeks ammonia to take over entirely and expects to implement such technology in 2030.

Aomori Proposes New Regional Rules for
‘Cohabitation’ with Renewables Projects
Last year, Aomori Prefecture’s incoming governor announced one of the most audacious plans for a regional tax on renewable energy projects in Japan, vowing to bring in a levy that would apply even to existing solar and wind farms. A year on, the prefecture’s strategy for the renewables sector looks quite different.
This month, a panel of experts employed by the prefecture published a skeleton draft of an ordinance that would see the local authorities assume greater control over solar and onshore wind projects. Specifically, the proposal targets operators with solar projects of over 2 MW in capacity (and 3 ha in size) and wind farms sized 500 kW and above.
The panel recommended that the prefecture use zoning rules, and placed an emphasis on installing an official community consultation procedure. The panel provided no details of a possible future tax.
After the rapid introduction of, in particular, solar power capacity in the last ten years or so, Japan has seen a slowdown in the rollout of new renewables facilities. Rising costs and dropping state tariffs for new projects were among the major factors, but a public backlash against new solar and wind farms in some communities has also been a serious issue in recent years. That has emboldened some municipalities, and even regional governments, to introduce new taxes or regulations to more closely control new developments.
In April, Miyagi became the first prefecture in Japan to introduce an ordinance that effectively taxes owners of new solar, wind or biomass generation facilities that cut down a certain level of forest cover to build the project. And so it was feared that Aomori would follow with an even more expansive tax plan.
New zoning concept
Aomori’s expert panel on renewables development was created earlier this year by Governor Miyashita Soichiro, who took office in June 2023. Soon after, Miyashita announced that he aimed at slowing down the proliferation of onshore wind projects, because, in his words, they were not meeting community interests. Aomori is the country’s top wind power producer, accounting for 20% of wind generation.
What the experts came back to the governor with is a little different from his 2023 pronouncements. Firstly, the draft of the proposed ordinance excludes offshore wind, residential rooftop solar, biomass, and hydro power sources.
It also states that the purpose of the new regulation in Aomori is not to discourage the local development of renewable energy, but to ensure that it expands in a smooth manner, avoiding environmental damage. The panel noted that most community conflicts in Aomori were related to solar and onshore wind farms.
Going forward, the panel proposes creating a zoning concept. This will restrict the areas where new solar and onshore wind projects can be sited. But even in the least restricted zone (a “cohabitation district”), a community council may need to be set up before an operator can even hold its first town hall meeting. This is the case if the community members and the operator seek to become “a renewables promotion district” as defined in the Act to Prevent Global Warming. The latter is important to help receive backing from the MoE, which has an important voice in decisions on large renewables projects.
The panel suggests introducing:
The prefecture will then make a judgment on whether proper communication took place or not before giving them a green light.
The proposal sees the need for two major zones: the “protected zones,” where renewable projects will be banned; and “cohabitation zones,” where projects are possible should they meet set requirements. There are two sub-categories in the latter zone: “preserved districts”; and “cohabitation districts”. Projects in the “preserved districts” will require approval from the municipalities in order to begin the local communication process.
In theory, renewable project development will be encouraged in the “cohabitation districts”, provided that there is no strong opposition.
Zone | Applicable Laws | Can renewables develop? |
Protected zone | Natural Park Act (high priority Type I and specially protected areas), Natural Environment Preservation Act (wildlife protection), Cultural Asset Protection Act, equivalent prefectural ordinances | Totally banned |
Cohabitation zone 1: Preserved district | Natural Park Act (lower priority Type II and III areas), Forestry Act | May be possible if projects have municipality support |
Cohabitation zone 2: Cohabitation district | Global Warming Act, Act on Renewables in Rural Areas | May be possible but a community council needs to be established; talks required over the zoning status if community members seek a “promotion status” as defined by the Global Warming Act, Act on Renewables in Rural Areas, etc. |
The panel also said it will write guidelines on the factors that project operators need to take into consideration when choosing sites. Their guidelines will include protection of livelihood and assets, consideration around disaster prevention and national defense issues, as well as requirements related to nature, landscape, history and culture.
The new communication procedure will involve:
The panel argues that under the present Environmental Impact Assessment process, which requires the operators to disclose scoping documents and survey results, there is no mechanism to reflect the interest of the municipalities directly affected by projects. The present system allows only the governor to submit opinions to the Environment Ministry and METI.
New tax
The panel was inconclusive about the new tax on renewable operators, an idea put forward by the governor last year. His initial plan was to levy a tax on all solar and wind operators, new and already operating. The panel did not discuss tax rates, to whom a potential tax will apply, or when. It said the scope of a renewable project’s tax will reflect its zoning category, environmental impact and project size.
The panel also clarified that tax rates should not be designed so as to chase away renewables operators. Further, any proceeds from a tax should be limited to promoting cohabitation, conservation, renewables development and similar, according to the panel’s findings.
The governor said last year he intended the revenue from a new renewables tax to be used freely, which would allow funds to be directed to causes unrelated to the environment.
Conclusion
The panel will need to work out details of the ordinance, including any new tax proposal, and these ideas would then need to get approval from the prefectural assembly.
The success of any new system that Aomori introduces will also depend on the clarity of its guidelines for defining zones. The MoE has already tried to spur the creation of various “renewables promotion zones” under the umbrella of the Global Warming Act, but this program has seen little takeup. Municipalities have been loath to strictly define such zones, and efforts to do so were complicated by competing stakeholders’ interests.
Still, Aomori may succeed in setting a precedent for introducing zoning-based ordinances and provide a template for local communication procedures, ideas that other prefectures could borrow. Introducing a new tax requires national government approval, but changing administrative rules is within the remit of prefectural authorities. Other regions may see this as a viable approach to control new developments.

This weekly column focuses on energy events in Asia and the Pacific
Australia / Nuclear power
The clean energy industry’s opposition to nuclear power is on two fronts: technological complexity and viability, and high costs. This was one of the main takeaways from last week’s Australian Clean Energy Summit 2024.
Canada / Oil exports
Asia’s crude oil imports from the expanded Trans Mountain pipeline will rise as major refiners in China, Japan and South Korea seek more supply. The flow of crude from Alberta to Canada’s Pacific coast will triple to 890,000 bpd. The pipeline gives Canadian producers more access to the U.S. West Coast and Asian markets.
China / Carbon emissions
China plans to cut carbon emissions in its coal power industry by piloting co-firing using coal mixed with either green ammonia or biomass, as well as with carbon capture, utilization and storage.
India / Russia
PM Modi and President Putin agreed to cooperate in energy, including nuclear power, oil refining and petrochemicals. Both are also looking into increasing the supply of coking coal, and exporting anthracite coal from Russia to India.
South Korea / Nuclear power
The Czech govt picked Korea Hydro & Nuclear Power (KHNP) as preferred bidder to build two nuclear reactors, marking South Korea’s first overseas order for a large-scale nuclear power project since 2009.
Sri Lanka / Energy transition
The Asian Development Bank granted Sri Lanka a $100 million policy-based loan to support reforms in the power sector introduced under the Electricity Act; this includes institutional and regulatory reforms that aim to improve operational sustainability of the electricity sector.
Thailand / Energy scandal
Share prices of Thai renewable energy company, Energy Absolute, plunged 30% in trading on July 16 after the lifting of a trade suspension following a leadership shake-up. Shares had been suspended on July 15 when the company announced changes to its board and senior management; the previous CEO was accused of fraud.
UAE / Green finance
State-backed green energy group Masdar raised $1 billion with its second green bond issuance on the London Stock Exchange. It was five times oversubscribed and is part of a larger effort to raise up to $3 billion to deploy 100 GW of renewable energy capacity by 2030. Masdar has a portfolio worth more than $30 billion.
U.S. / LNG exports
A U.S. court ordered the Federal Energy Regulatory Commission to reassess the impact of GHGs from Commonwealth LNG’s project in Louisiana. By 2027, the government aims to cut average carbon emissions by 50% from 2023 levels.
Vietnam / Renewable energy
Vietnam’s renewable energy developers are set to benefit from a newly approved mechanism for direct power purchase agreements, said Saigon Securities, adding that the DPPA can encourage more investment in domestic renewable energy, thus improving efficiency of the country’s power market.
