In 2025, the pieces are rapidly assembling to enable and accelerate imports of ammonia energy to Japan. This year, government agency METI is due to announce two lots of key funding, including contracts for difference subsidies and development of import infrastructure. Power generation technologies will be commercialised within the next few years, and more maritime players are joining the push to deploy ammonia fuel in Japanese ships.

JERA and IHI have successfully concluded a large-scale ammonia co-firing trial at the Hekinan power station. For two months, 20% fuel substitution in the 1 GW-sized Unit 4 was achieved, with stable operations throughout. JERA aims to have commercial ammonia co-firing operations up and running by March 2025.

With installation and testing of ammonia fuel equipment now complete, a 20% ammonia co-firing demonstration will proceed from April to June this year at the Hekinan power plant. JERA and IHI aim for commercial operations to begin around March 2025. JERA is also exploring part ownership and offtake from Exxon Mobil’s CCS ammonia mega-project in Baytown, Texas.

ACME and IHI have signed an offtake agreement for the supply of renewable ammonia from the pair’s under-development production plant in Odisha, eastern India. On a long-term basis, 400,000 tons per year will be transported, with production to begin in 2027. A number of other Indian production projects were launched this month.

IHI Corporation will join the North Queensland Clean Energy Project, a consortium developing a GW-scale electrolysis, ammonia production and export facility in north Queensland, Australia. Project partners include Idemitsu Australia, CS Energy and Energy Estate.

The pair will jointly develop a 1.3 million tonnes per year renewable ammonia production plant in the Gopalpur Industrial Park in Odisha, northeast India. From the adjacent port, ammonia will be shipped domestically, and exported to key global markets.

ACME and IHI will assess the feasibility of potential joint projects in the ammonia energy space, including production, transportation, distribution, and power generation. Also this week, IHI and GE have presented their findings from an ammonia-powered gas turbine feasibility study, with some favorable fuel economics for ammonia.

Japanese government funding via NEDO will support four critical ammonia energy projects, including JERA's new plan to demonstrate 50% ammonia-coal co-firing by 2030. Other projects include improved catalysts for ammonia production, low-temperature and low-pressure synthesis pathways, and developing 100% ammonia-fed boilers and gas turbines. In addition, a new cooperation agreement between ASEAN countries will see Japan support other members to adopt their ammonia energy solutions, particularly coal co-firing.

Mitsubishi Power has announced the development of single and mixed-fuel ammonia combustion boilers for industrial applications. Importantly, Mitsubishi also announced that optimal combustion conditions for ammonia have been successfully identified to minimise NOx formation and ammonia slip.

This week: 45 GW mega-project in Kazakhstan, world-first industrial "dynamic" green ammonia plant, Japan's Idemitsu to use Tokuyama facility for ammonia imports, co-combustion test, more successful funding rounds, green ammonia in Ireland, South Africa's potential to fuel green shipping: new report, Obsky LNG becomes Obsky hydrogen/ammonia and more developments in the Middle East.

Welcome to the Ammonia Wrap: a summary of all the latest announcements, news items and publications about ammonia energy. This week: two new large-scale ammonia projects in the UAE, RWE, BASF combine for 2 GW "Offshore-to-X" project, green ammonia exports from Tasmania, coal co-combustion trials in Japan, Japanese shipping industry chases decarbonisation, South Korean companies join together in local green ammonia consortium, new funding for ammonia-from-wastewater research and Horisont Energi and Equinor join forces for the Polaris project.

Last week, Japan’s Ministry of Energy, Trade, and Industry (METI) announced the formation of a council to work on the implementation of ammonia as an energy commodity. The announcement came on the same day as a speech by Prime Minister Yoshihide Suga in which he established 2050 as the date certain for Japan to achieve carbon-neutrality. That was Monday October 26, 2020. The council held its first meeting on Tuesday October 27. The Council consists of four entities from the public sector and ten from the private sector. Members include companies that have previously been identified with the development of ammonia energy systems, including EPC firm JGC, capital goods manufacturer IHI, electric utility JERA, and shipping company NYK Line. The membership also reflects what appears to be the group’s central mission: positioning Japan as ammonia energy’s global leader via the dissemination of technology and the development of supply chains.

From 2014 to 2018 Bunro Shiozawa served as Deputy Program Director of the SIP “Energy Carriers” initiative in Japan. Over the last year he has published a ten-part series of articles that describe and reflect on the research supported by the initiative. Part 4 covers ammonia combustion technologies. The first half of the article was posted on September 23, 2020, in Shiozawa's English translation. The second half follows.

In March 2020, IHI Corporation, JERA Co., and Marubeni Corporation announced a feasibility study "to evaluate possible applications for the co-firing of ammonia in thermal power plants." The Japanese companies have contracted with NEDO to deliver detailed technical and economic analysis on the use of ammonia as a direct fuel for power generation. In addition, with support from Woodside Energy in Australia, they "will examine the construction and operation of world-scale ammonia facilities and the optimisation of supply chain costs" to support "large-scale export of hydrogen as ammonia."

Japan’s Green Ammonia Consortium, an industry body dedicated to building “a value chain from supply to use of CO2-free ammonia,” launched its Web site on December 5. The site features plenty of interesting content, but most significant may be the roster of members. Eighty seven companies, public organizations, and individuals are listed. Taken together they represent a significant force for ammonia energy implementation in Japan and beyond.

Japanese capital goods manufacturer IHI Corporation announced last month that it has started construction of a 1,000 square-meter hydrogen research facility in Fukushima Prefecture.  The facility will be an addition to IHI’s Green Energy Center in Soma City which was launched in 2018.  One of the Center’s original focuses is the production steps of the green hydrogen supply chain using solar electricity to power developmental electrolyzers.  The new facility will focus on hydrogen carriers, including ammonia and methane (via “methanation” of carbon dioxide), that can be used in the logistics steps of the supply chain.

ETN Global’s latest R&D Recommendation was released in October 2018.  ETN stands for European Turbine Network and its technology of interest is the gas turbine.  The 2018 Recommendation is notable because it is the first that includes ammonia on the R&D agenda.

In the last 12 months ... IHI Corporation tested its 1 kW ammonia-fueled solid oxide fuel cell (SOFC) in Japan; Project Alkammonia concluded its work on cracked-ammonia-fed alkaline fuel cells (AFC) in the EU; the University of Delaware's project for low-temperature direct ammonia fuel cells (DAFC) continues with funding from the US Department of Energy's ARPA-E; and, in Israel, GenCell launched its commercial 4 kW ammonia-fed AFC with field demonstrations at up to 800 locations across Kenya.

The Japanese manufacturer IHI Corporation announced on March 28 that it had successfully demonstrated the co-firing of ammonia and coal in a fuel mix composed of 20% ammonia. Ammonia-coal co-firing had previously been demonstrated by Chugoku Electric in a fuel mix composed of just 0.6-0.8% ammonia. IHI says its ultimate goal is to “construct a value chain that connects the production and use of ammonia, using combustion technology of gas turbines and coal-fired boilers, using ammonia as fuel.”

On December 8, the Nikkei Sangyo Shimbun ran a story about the future of coal-fired electricity generation in Japan.  The story touched on topics ranging from the plumbing in a Chugoku Electric generating station to the Trump administration’s idiosyncratic approach to environmental diplomacy.  And it contained this sentence: “Ammonia can become a ‘savior’ of coal-fired power.” Clearly an explanation is in order.

In the last 12 months ... Researchers seeking to fire gas turbines with ammonia made significant strides toward realization of commercial-scale machines in both the U.K. and Japan. This means that electricity generation has become a realistic near-term use-case for ammonia energy.

On July 25, the Japan Science and Technology Agency (JST) announced that a collection of companies and research institutions had come together to form a Green Ammonia Consortium.  The 22-member group will take over responsibility for the ammonia aspect of the Cross-Ministerial Strategic Innovation Program (SIP) Energy Carriers agenda when the SIP is discontinued at the end of fiscal 2018.  A JST press release states that the Consortium intends to develop a strategy for “forming [an] ammonia value chain,” promote demonstration projects that can further commercialization, and enable “Japanese industry to lead the world market.”

Most of the ammonia energy projects I write about are in the research and development phase but, as I've said before, technology transfer from the academic lab to commercial deployment is moving swiftly - especially in Japan. Last week, Nikkei Asian Review published two articles outlining plans by major engineering and power firms to build utility-scale demonstrations using ammonia as a fuel for electricity generation. Both projects aim to reduce the carbon intensity of the Japanese electrical grid, incrementally but significantly, by displacing a portion of the fossil fuels with ammonia. The first project will generate power using an ammonia-coal mix, while the second will combine ammonia with natural gas.

A common concern with ammonia fuel is that NOx emissions will be too high to control. However, in new research from Turkey, USA, and Japan, presented at this year's NH3 Fuel Conference in September 2016, two things became clear. First, NOx emissions can be reduced to less than 10ppm by employing good engineering design and exploiting the chemical properties of ammonia, which plays a dual role as both the fuel and the emissions-cleanup agent. Second, the deployment of ammonia-fueled turbines for power generation is not only feasible, but actively being developed, with demonstration units running today and improved demonstration projects currently in development.
