Japan looks to US, Australia for ammonia supply chain
Japan is looking to invest in blue and green ammonia development projects in the US and Australia under a strategy to control the entire ammonia value chain and reduce costs in the long run, executive vice president of Clean Fuel Ammonia Association (CFAA) Shigeru Muraki told Argus.
Tokyo considers ammonia as a strategic energy resource like oil and gas. Japan is seeking to establish a global ammonia value chain of 100mn t/yr by 2050 and take full control over the supply chain to meet its growing demand and tap potential demand growth in Asia under a strategy roadmap that was drawn up at a public-private council to achieve the country's decarbonisation goal.
This is the first time that Japan has formed a public-private partnership to co-operate in a major fuel transition. CFAA, a group of Japanese and overseas firms, state agencies and global research institutions, aims to co-ordinate efforts by companies from various industries that are involved in the entire value chain, with government financial, regulatory and diplomatic support in launching a scheme for the new fuel.
"We want a structure where Japanese firms participate in an entire value chain including the upstream part and can reduce overall costs. Ammonia offers the possibility," Muraki said in an interview on 26 February.
Muraki, who is also executive advisor for utility Tokyo Gas, compared the joint public-private effort to usher in fuel-use ammonia with Japan's shift to LNG more than 50 years ago — something that was carried out as a purely private-sector initiative. Tokyo Gas and fellow utility Tokyo Electric Power in 1969 started importing 960,000 t/yr of LNG from the Alaska LNG project in the US under a 15-year agreement with ConocoPhillips, followed by imports from Brunei in 1972 and Indonesia in 1977.
The government later urged and assisted Japanese energy firms to acquire upstream gas and LNG assets as part of efforts to secure stable supply and enhance energy security as the fuel's role and import volume grew. But majors and national oil companies have dominated access to profitable upstream assets, while Japanese firms acquired only limited upstream shares in new LNG projects. These are mostly in Australia such as the Ichthys, Queensland Curtis LNG (QCLNG) and Gorgon projects.
Public-private backing
"It gave us a big help that the trade and industry ministry launched a council to prompt collaboration between the government and private industries in introducing ammonia as a fuel," Muraki said, referring to the speed of the policy development process — particularly in the last 18 months — after Japan started the discussing possible use of ammonia as a fuel in 2013.
New blue and green ammonia development projects on the US Gulf coast, such as Texas and Louisiana, and in Australia and maybe Chile, offer attractive investment environmental and business transparency, Muraki said. A number of Japanese firms have agreed on joint feasibility studies to develop blue and green ammonia and hydrogen projects overseas, including Australia, New Zealand, Malaysia and Russia.
Japan is also keen to work with Middle East oil-producing countries to develop ammonia supply chain projects as part of its strategy to maintain strong ties and secure stable oil supply, he said. In contrast to US and Australian projects based on a private business partnership, diplomatic relations will also have to be taken into consideration for Middle East projects. The Middle East supplied more than 90pc of Japan's crude oil imports last year.
Muraki is personally interested in ammonia development in Oman, which has potential as a green ammonia supplier because of its ample solar and wind resources. Ammonia supply from Oman can also be delivered without passing through the strait of Hormuz, he added. Japanese trading house Sumitomo in January launched a feasibility study to develop a hydrogen supply chain in Oman.
Japanese demand for ammonia fuel is likely to be initially met with grey ammonia, depending on its availability and cost, as the country prioritises the quick establishment of a market for ammonia. Muraki expects it will take several years for a large-scale blue ammonia project to reach commercialisation and start new supply, including the carbon capture and storage (CCS) process.
Tokyo is considering financial support for costly CCS, prompting Japanese firms to invest in more upstream oil and gas development, as well as in development of ammonia and hydrogen value chains that include the upstream part of the chain.
Hub plans
CFAA is mulling plans for a hub terminal that can import green and blue ammonia on dedicated ammonia carriers and distribute it on coastal vessels to distant industrial consumers, in line with the transport ministry's strategy to develop a carbon-neutral port at the country's six key ports. Three of the six ports — Tokuyama-Kudamatsu in western Japan's Yamaguchi prefecture, Niigata on Japan's northwest coast and Onahama on the northeast coast — hold the potential for a hub as they already have infrastructure and host major industrial complexes, according to Muraki.
But Muraki ruled out domestic production of blue ammonia for fuel use using LNG as a feedstock because of its high costs and limited land availability for CCS. High renewable power prices will also make domestic output of green ammonia unworkable for use as a fuel, particularly thermal fuel.
CFAA was launched in 2019 to develop a value chain of blue and green ammonia for fuel use and help achieve a decarbonised society. The group is expected to work out international standards for the fuel use of ammonia, as well as a certification scheme for the footprint of an ammonia supply chain, over the coming years in the run-up to the expected start of Japanese fuel-use ammonia imports by 2025.
Shigeru Muraki is among the speakers at the Argus Green Ammonia Live – Virtual Conference, which takes place on 24-25 March. For details of the conference programme and registration, please visit www.argusmedia.com/green-ammonia

Iraq to keep 3.3mn b/d crude export cap until year end
Iraq to keep 3.3mn b/d crude export cap until year end
Dubai, 24 April (Argus) — Iraq will stick to its pledge to cap crude exports at 3.3mn b/d until the end of the year, regardless of what the Opec+ coalition decides at its June meeting, sources with knowledge of the matter told Argus. Baghdad announced the 3.3mn b/d export limit last month , representing a 100,000 b/d cut compared with the first-quarter average. April's exports will be in line with recent months, according to the sources, indicating that Iraq has yet to adhere to the cap. The self-imposed limit on exports is part of Iraq's commitment to compensate for exceeding its 4mn b/d Opec+ production target in the first three months of 2024. It produced 211,000 b/d above target in January, then overshot by 217,000 b/d and 194,000 b/d in February and March, respectively, according to an average of secondary sources including Argus . Prior to that, Iraq exceeded its then 4.22mn b/d output ceiling in each of the last six months of 2023. The persistent overproduction has drawn scrutiny within Opec+, prompting repeated reassurances from Baghdad in recent months that it is committed to its output pledges. Iraq blames it on its inability to oversee production in the semi-autonomous Kurdistan region in the north of the country. Most Iraqi Kurdish crude output is being directed to local refineries or sold on the black market following the closure of the export pipeline that links oil fields in northern Iraq to the Turkish port of Ceyhan just over a year ago. Iraq's federal oil ministry says its Kurdish counterpart has stopped providing production data. Baghdad recently sent the Kurdistan Regional Government (KRG) an official request to hand over oil produced in the region to federal marketer Somo in order to resume Kurdish exports through Turkey, the sources said. Baghdad also urged the KRG back in January to curb output to help Iraq adhere to its lower Opec+ production quota. Ever-widening gap The Association of the Petroleum Industry of Kurdistan (Apikur) said international oil companies (IOCs) operating in the region were hoping that a long-awaited visit to Baghdad by Turkish president Recep Tayyip Erdogan on 22 April might help pave the way for a restart in exports. "We definitely believe the Iraqi government seems more serious about resolving the issues after prime minister [Mohammed Shia] al-Sudani's visit to the US," an IOC source told Argus. But differences between the KRG and Baghdad, mainly over contracts that the former signed with international oil companies (IOCs) in Kurdistan, continue to delay the restart. And tensions between the two sides show little sign of easing. In a statement on 22 April, the KRG's ministry of natural resources accused Baghdad of misleading statements by seeking to blame the KRG for the export shut-in, adding that there is no provision in Iraq's constitution that gives power to the federal government to approve contracts issued by the KRG. With the help of multiple federal court rulings, Baghdad has been attempting to downgrade the KRG's autonomy over its finances and energy sector. A court ruling in February 2022 overturned a law governing Kurdish oil and gas exports and upheld Baghdad's request that all KRG production-sharing contracts be placed under federal oil ministry oversight. The judgment rendered the KRG's 2007 oil and gas law unconstitutional, raising questions over the future of the KRG's active contracts. The KRG's natural resources ministry has dismissed the February 2022 court order, saying it was delivered by a "committee of political appointees in Baghdad". While the federal Iraqi oil ministry "publicly refers to that committee as the 'Federal Supreme Court', everyone knows that it is no such thing", the ministry said.

EU adopts sustainability due diligence rules
EU adopts sustainability due diligence rules
Brussels, 24 April (Argus) — The European parliament has formally approved a Corporate Sustainability Due Diligence Directive (CSDDD), which will require large EU companies to make "best efforts" for climate change mitigation. The law will mean that relevant companies will have to adopt a transition plan to make their business model compatible with the 1.5°C temperature limit set by the Paris climate agreement. It will apply to EU firms with over 1,000 employees and turnover above €450mn ($481mn). It will also apply to some companies with franchising or licensing agreements in the EU. The directive requires transposition into different EU national laws. It obliges member states to ensure relevant firms adopt and put into effect a transition plan for climate change mitigation. Transition plans must aim to "ensure, through best efforts" that business models and company strategies are compatible with transition to a sustainable economy, limiting global warming to 1.5°C and achieving climate neutrality by 2050. Where "relevant", the plans should limit "exposure of the company to coal-, oil- and gas-related activities". Despite a provisional agreement, EU states initially failed to formally approve the provisional agreement reached with parliament in December, after some member states blocked the deal. Parliament's adoption — at its last session before breaking for EU elections — paves the way for entry into force later in the year. Industry has obtained clarification, in the non-legal introduction, that the directive's requirements are an "obligation of means and not of results" with "due account" being given to progress that firms make as well as the "complexity and evolving" nature of climate transitioning. Still, firms' climate transition plans need to contain "time-bound" targets for 2030 and in five-year intervals until 2050 based on "conclusive scientific" evidence and, where appropriate, absolute reduction targets for greenhouse gas (GHG) for direct scope 1 emissions as well as scope 2 and scope 3 emissions. Scope 1 refers to emissions directly stemming from an organisation's activity, while scope 2 refers to indirect emissions from purchased energy. Scope 3 refers to end-use emissions. "It is alarming to see how member states weakened the law in the final negotiations. And the law lacks an effective mechanism to force companies to reduce their climate emissions," said Paul de Clerck, campaigner at non-governmental organisation Friends of the Earth Europe, pointing to "gaping" loopholes in the adopted text.

Norway-German H2 pipeline hinges on demand: Equinor
Norway-German H2 pipeline hinges on demand: Equinor
London, 24 April (Argus) — Norway and Germany have renewed a commitment to the idea of a hydrogen pipeline, but Norwegian state-owned Equinor expects the link will come in a secondary stage of development as it is focused on hydrogen production in mainland Europe as a first step. Equinor plans to take a final investment decision in late 2025 on its 210,000 t/yr Eemshaven low-carbon hydrogen plant in the Netherlands, the company's director of H2 northwest Europe Henrik Solgaard Andersen said at the Hydrogen and Fuel Cells conference in Hanover. Equinor hopes the project will supply German buyers that participate in the country's carbon contracts for difference (CfD) auctions, which are designed to help large industry decarbonise, Andersen said. Equinor has entered the final phase of studies for the plant. The facility would reform natural gas from the Norwegian offshore to hydrogen with carbon capture and storage (CCS). Undertaking this in the Netherlands means existing pipelines can be used to carry the gas from Norway rather than having to build new links. Equinor sees this as its most mature hydrogen project, followed by one near the German port of Rostock , and one near Ghent in Belgium , according to Andersen. These "local European projects" are designed for early market development and "will be the first step," he said. Equinor expects to start large-scale production of hydrogen in Norway with pipeline exports to the continent only when there is a big enough market, he said. "You don't invest in a pipeline €4bn-6bn just for [transporting] a few molecules," he said. "You need to believe in the market." Equinor in early 2023 announced a plan to supply hydrogen from Norway to German utility RWE for use in power plants. But Berlin has shifted its plans for hydrogen power a couple of times since then. It also has ambitions to use hydrogen in sectors like steel, but companies have not yet taken firm investment decisions, meaning there is uncertainty about how much hydrogen demand will materialise and when. A joint government task force working on a Norwegian-German pipeline has identified the first regulatory barriers that need to be addressed, and private infrastructure companies will continue to study the logistics, according to an announcement from Oslo and Berlin. This will build on the positive feasibility study from last year. German gas system operator operator Gascade, which is developing the AquaDuctus North Sea pipeline connection to Germany, and Norwegian state-owned operator Gassco that is developing the Norwegian side, are aiming for a 2030 start date, the companies reaffirmed this week. Gascade has proposed an open access pipeline that would be able to aggregate hydrogen exports from England, Scotland, Norway, Denmark, and North Sea wind farms.

Oman latest to insist that oil, gas is 'here to stay'
Oman latest to insist that oil, gas is 'here to stay'
Muscat, 24 April (Argus) — Omani and Oman-focused energy officials this week joined a growing chorus of voices to reiterate the pivotal role that hydrocarbons have in the energy mix, even as state-owned companies scramble to increase their share of renewables production. Some producers cite the risk of leaving costly, stranded oil and gas assets as renewable energy alternatives become more favoured. "This is a common concern among producers who are focusing on short-term developments to maximize cash flow — [but] if we continue to do that, with the clean energy transition, will we be left with stranded assets in the long-term", state-controlled PDO's technical director Sami Baqi told the Oman Petroleum and Crude Show conference in Muscat this week. "We need to redefine and revamp our operation model to produce in a sustainable manner." "We are in an era where most of the production does not come from the easy oil but comes from difficult oil," Oman's energy ministry undersecretary Mohsin Al Hadhrami said. "It requires more improved and enhanced oil recovery (EOR) type technologies to extract it." Oman is heavily reliant on tertiary extraction technologies like EOR given its maturing asset base and complicated geology. "We know that most of the oil fields [in the region] are maturing and costs are going to escalate, so we need to be mindful of it while discussing cleaner solutions going forward," Hadhrami said. PDO, Oman's largest hydrocarbon producer, aims for 19pc of its output to come from EOR projects by 2025, and has said it is looking at 'cleaner' ways to implement the technology. PDO in November started a pilot project to inject captured CO2 for EOR at its oil reservoirs. Baqi's concerns were echoed by PDO's carbon capture, utilisation and storage (CCUS) manager Nabil Al-Bulushi, who said even solutions like CCUS can be expensive and come with their own challenges. There is a need for a proper ecosystem or regulatory policies to avoid delays in executing such projects, he said. When it comes to challenges associated with commercialising green hydrogen, Saudi state-controlled Aramco's head of upstream Yousef Al-Tahan said higher costs already make hydrogen more expensive than any other energy sources. "Not only should the costs go down, but the market has to be matured to take in the hydrogen," he said. "We also need pipelines and facilities that are able to handle hydrogen, especially when it gets converted to ammonia." Gas here to stay Oman, like many of its neighbors in the Mideast Gulf, insists gas needs to be part of the global journey towards cleaner energies. "Asia-Pacific is still heavily reliant on coal, this is an area where gas can play an important role," Shell Oman's development manager Salim Al Amri said at the event. "I think there is no doubt that gas is here to stay." Oman is a particularly interesting case as it "has moved from a position of gas shortage to surplus", Al Amri said, enabled by key developments in tight gas. "Output from fields like Khazzan and Mabrouk will continue to produce nearly 50pc of output even by 2025, which is indicative of how important tight gas developments are," he said. The Khazzan tight gas field has 10.5 trillion ft³ of recoverable gas reserves. Mabrouk North East is due to reach 500mn ft³/d by mid-2024. But even as natural gas is touted as the transition fuel, executives from major producers like state-owned OQ and PDO warned there are technical risks associated with extracting the fuel, including encountering complex tight reservoirs, water production and difficult geology.
