During the recent AEA Annual Conference 2024, the status of ammonia as fuel for gas turbines was discussed, featuring a panel of global OEMs and gas turbine experts. We explore the technology developments to date, different fuel strategies for ammonia, demonstration projects planned, and the pathway forward for deployment.

We highlight ammonia developments in Taiwan in line with the island nation’s plans to achieve net-zero emissions by 2050:

• Taiwan’s largest fertiliser manufacturer, Taiwan Fertiliser Company, will collaborate with ammonia industry giants Mitsubishi Heavy Industries and IHI Corporation to develop a low-carbon ammonia supply chain.
• Taipower, IHI and Sumitomo have an agreement in place to develop a 5% ammonia-coal co-firing demonstration project at Taipower’s Dalin Power Plant by 2030.
• And ITOCHU and U-Ming Marine Transport’s partnership for the joint ownership and operation of ammonia-fueled ships.

Multiple ammonia import bases are under development in Asia. In Singapore, Vopak and Air Liquide will explore new infrastructure on Jurong Island. In South Korea, Ulsan Port Authority and NGO Pacific Environment will cooperate to accelerate the transition of Ulsan into an “eco-friendly” port. And in Japan, IHI will lead two study consortia exploring new supply and distribution hubs in Hokkaido and Fukushima.

GE Vernova and IHI Corporation will proceed to the engineering and testing phase for their ammonia gas turbine roadmap for Asia. Based on their efforts in 2022 to demonstrate a low-N₂O combustor for a 2 MW, 100% ammonia-fired turbine, IHI will lead development of a two-stage combustor for larger-scale gas turbine models.

IHI & Vopak will explore the development and operation of large-scale ammonia terminals in Japan, focused on the cost-effective distribution of ammonia imports. In the Netherlands, Proton Ventures reports that work on the conversion of Vesta Terminal’s existing site into an ammonia import hub is on schedule for FID to be made by 2024. And in other Proton Ventures news, the organisation has been awarded a FEED contract with Geldof to develop an ammonia terminal in Western Africa.

Sembcorp, IHI and GE will explore potential retrofits to existing gas turbines at the Sakra power plant to run on 100% ammonia fuel. The Sakra plant currently features two GE 9FA turbines, which are among the models IHI & GE are targeting for development of a “retrofittable” ammonia combustion system.

Mitsui & Co., Mitsui Chemicals, IHI Corporation and the Kansai Electric Power Company will explore the establishment of a hydrogen & ammonia supply chain based in Osaka. Ammonia fuel will be used to decarbonise electricity generation, and cracked to provide a feedstock for other industrial processes like steel-making. In South Korea, a similar partnership is evolving between LOTTE and Air Liquide. You can learn more about the emerging nexus between ammonia cracking and steel-making at our upcoming annual conference in Atlanta, USA.

Adani Power and two Japanese organisations - IHI Corporation and Kowa - have signed a new MoU to conduct a feasibility study into 20% ammonia-coal co-firing at the Mundra power plant in Gujarat, India. The trio will also investigate increasing this co-firing percentage all the way up to 100% ammonia fuel (“mono-firing”). The new MoU contributes to a national-level partnership announced last week - the "India-Japan Clean Energy Partnership (CEP)".

Woodside Energy secured land this week for its H2TAS project in Bell Bay, Tasmania. A long-term lease on a partially-cleared project site nearby the Bell Bay Advanced Manufacturing Zone will be home to up to 1.7 GW of electrolysers, and a target production of 200,000 tonnes per year green ammonia. Last month Woodside also announced the H2Perth project: a world-scale, 1,500 tonnes per day hydrogen production facility aimed at local markets for refueling fuel cell vehicles, and international markets via export in the form of liquefied hydrogen or ammonia.

Woodside Energy, JOGMEC, Marubeni and two Japanese power utilities signed a joint research agreement this week to investigate the feasibility of a blue ammonia supply chain between Australia and Japan.

This week: a roadmap for ammonia-fueled gas turbines in Asia, ammonia solutions in Iceland, IMO sets new decarbonisation milestone, new ammonia-powered vessels planned, maritime study developments, Australian updates (Fortescue, AREH and Itochu in Gladstone), Fertiglobe joins Abu Dhabi blue ammonia project and Statkraft's Porsgrunn plans.

This month, the Japanese Ministry for Economy, Trade, and Industry (METI) began promoting an updated Road Map for Fuel Ammonia, focused on the use of ammonia in thermal power plants and as a shipping fuel. By 2030, Japan expects to import 3 million tons of clean ammonia, with demand rising to 30 million tons by 2050. To secure these volumes, Japanese companies are now making investments up and down the supply chain. These are ambitious numbers, matching Japan’s recent commitment to reach net-zero emissions, but still they miss the big picture. The broader economic opportunity arrives when Japanese companies export their fuel ammonia technologies, decarbonizing coal-fired power plants across Asia, and then supply the fuel to these newly sustainable shipping and electricity sectors. By 2050, the METI Road Map expects Japanese trading companies to supply the wider region with 100 million tons per year of clean ammonia.

This week, Japan’s new Prime Minister Yoshihide Suga announced that by 2050 the country would drive its greenhouse gas emissions to zero and achieve carbon-neutrality. Earlier in the month, the Japanese electric utility JERA announced its intention of “achieving zero CO2 emissions by 2050.” Its first step toward this goal was its 'JERA Zero CO2 Emissions 2050 Roadmap for its Business in Japan.'

In recent weeks, the Japanese shipping company NYK Line has announced a series of high-profile research and development collaborations that aim to establish ammonia fueled vessels and fuel supply. Its partners in these projects include classification society Class NK, engine manufacturer IHI Power Systems, and shipbuilder Japan Marine United Corporation. Three vessel types have been announced, so far, including an ammonia-fueled ammonia gas carrier, an ammonia barge for offshore bunkering, and an ammonia-fueled tugboat (for navigating the barge). Pushing beyond the initial research phase, these collaborations aim for commercialization and to put these vessels “into practical use.”

A steady stream of Japanese news reports over the last several months attest to the country’s progress in deploying fuel cells in the built environment. Dubbed “Ene-Farms,” the appliances function as micro-scale combined heat and power units, providing electricity as well as heat for domestic applications. Most of the Ene-Farms deployed so far feature proton-exchange membrane (PEM) technology (which requires high-purity hydrogen). However, two recent developments show that solid oxide fuel cell (SOFC) technology (well suited for ammonia) could play a role, maybe even a large role, in Japan's Hydrogen Society.

This week, an article in Japan Chemical Daily disclosed IHI Corporation's future plans for its range of ammonia combustion technologies, each of which has been demonstrated in the last year. These include "ammonia-coal co-fired thermal power boilers, ammonia-fired gas turbines and direct ammonia solid oxide fuel cells (SOFCs)." Under the headline "IHI Speeds up Development of Several Ammonia-Based Technologies," the article describes the company's ambitions for scaling-up each of these technologies, and provides a schedule for its next set of demonstration projects.

ANNOUNCEMENT: The Japanese Government’s Cabinet Office and the Japan Science and Technology Agency have released an English-language video that summarizes the accomplishments of the Cross-Ministerial Strategic Innovation Promotion Program’s Energy Carriers initiative.  The release coincides with the end-of-March conclusion of Energy Carriers’ work, and anticipates this month’s formal activation of the Green Ammonia Consortium.

Japanese manufacturing concern IHI reported on May 16 that it had “successfully generated 1 kW class power” from a direct ammonia solid oxide fuel cell.  This is the latest milestone for a technology that could play a major role in the roll-out  of Japan’s Hydrogen Society.

During his presentation at the November 2017 NH3 Energy + Topical Conference, Shogo Onishi of IHI Corporation described the progress made by IHI and Tohoku University in limiting NOx emissions from ammonia-fired gas turbines (AGTs).  Regular attendees of the annual NH3 Fuel Conference identify IHI with its work on AGTs since the company also addressed this topic at the 2016 and 2015 events.  However, a scan of published materials shows that AGTs are just one aspect of IHI’s activity in the ammonia energy arena.  In fact, IHI is also looking at the near-term commercialization of technologies in ammonia-coal co-firing in steam boilers and direct ammonia fuel cells.  This level and breadth of commitment to ammonia energy is unique among global capital goods producers.

To demonstrate the progress of the SIP "Energy Carriers" program, the Japan Science and Technology Agency last week released a video, embedded below, that shows three of its ammonia fuel research and development projects in operation. R&D is often an abstract idea: this video shows what it looks like to generate power from ammonia. As it turns out, fuel cells aren't hugely photogenic. Nonetheless, if a picture is worth a thousand words, this will be a long article.

In the last 12 months ... In July 2017, 19 companies and three research institutions came together to form the Green Ammonia Consortium. Before this development, it was unclear whether ammonia would find a significant role in Japan’s hydrogen economy. In the wake of this announcement, however, ammonia seems to have claimed the leading position in the race among potential energy carriers.

Earlier this month the Eguchi Laboratory at Kyoto University announced advances in ammonia-fueled solid oxide fuel cell technology.  The lab was able to produce a functioning fuel cell with a power output of one kilowatt.  The device attained “direct current power generation efficiency” in excess of 50% and reached 1,000 hours of continuous operation.

I wrote last week about ARPA-E's "transformative" ammonia synthesis technologies, describing three technology pathways under development: low pressure Haber-Bosch, electrochemical processes, and advanced electrolysis. ARPA-E's ambitious R&D program might imply that a meaningful, commercial market for sustainable ammonia is still decades away. It represents, however, only the slow American tip of a fast-moving global iceberg. In Japan, where there's no debate about climate science, the national effort is already well underway, with three programs to develop low-carbon ammonia synthesis under the Cross-ministerial Strategic Innovation Promotion Program (SIP), 'Energy Carriers.'
