Advancements in Ammonia-to-Hydrogen Technology Support Decarbonization

The conversion of ammonia into hydrogen is gaining momentum as utilities and heavy industry search for scalable pathways to decarbonize operations. Industrial-scale ammonia cracking systems are moving toward commercial maturity across Europe, Asia, and the United States, positioning ammonia as a practical energy carrier in the evolving hydrogen economy.

Ammonia offers several structural advantages. It has a higher volumetric hydrogen density than liquid hydrogen and benefits from a century-old global infrastructure for shipping, storage, and handling. For power generation, ammonia can be “cracked” at high temperatures, typically between 600°C and 900°C, over catalysts that separate it into nitrogen and hydrogen. The hydrogen can then be used in proton exchange membrane fuel cells, hydrogen engines, or co-fired in turbines increasingly designed to handle hydrogen blends. Manufacturers such as GE Vernova are developing turbines capable of burning 30 percent or more hydrogen, with efforts underway toward 100 percent hydrogen combustion.

 

Amogy and the Ammonia Cracking Breakthrough

 

Brooklyn-based Amogy, which operates manufacturing facilities in Houston, has developed proprietary ammonia cracking technology that splits ammonia into nitrogen and hydrogen with improved efficiency, lower operating temperatures, and a smaller system footprint.

The produced hydrogen feeds integrated fuel cells or hydrogen engines to generate carbon-free electricity. The company targets hard-to-abate sectors including maritime shipping, distributed power generation, and heavy industry.

In 2025, Amogy powered what it described as the world’s first ammonia-fueled vessel on the Hudson River. The NH3 Kraken tugboat, originally diesel-powered, was retrofitted with an ammonia-to-electric power system designed to operate without carbon emissions.

Seonghoon Woo, CEO of Amogy, has emphasized ammonia’s role as a hydrogen carrier that overcomes storage and transport barriers. While hydrogen infrastructure is still developing, ammonia benefits from existing logistics networks built over decades for agricultural and industrial use. According to Woo, unlocking ammonia’s potential required efficient cracking technology, which the company says it has achieved through advanced catalyst development.

South Korea: Distributed Ammonia-to-Power

 

In Pohang, South Korea, Amogy is preparing to deploy an ammonia-based distributed power system beginning with a 1 MW pilot project, with plans to scale to 40 MW by 2029.

The initiative involves collaboration with GS Engineering & Construction, HD Hyundai Infracore, and the city of Pohang. Amogy’s cracking technology will integrate with HD Hyundai’s HX22 hydrogen engine, while GS E&C supports infrastructure development and system operations.

The project aligns with South Korea’s Distributed Energy Act and broader hydrogen policy framework. Officials in Pohang aim to position the region as a clean energy innovation hub, combining research, infrastructure, and commercial deployment.

 

Taiwan and Singapore: Expanding Regional Deployment

 

Amogy has also partnered with Taiwan-based GreenHarvest to deploy an ammonia-to-power system at a large industrial facility, with installation expected between late 2026 and early 2027. The pilot could expand into Taiwan’s manufacturing and high-tech sectors, where reliable low-carbon energy is increasingly critical.

In Singapore, Amogy signed a memorandum of understanding with Agency for Science, Technology and Research (A*STAR) to explore ammonia-to-power pilots on Jurong Island. The collaboration supports objectives under the Singapore Green Plan 2030 and the country’s National Hydrogen Strategy.

These projects highlight Asia-Pacific markets as early adopters, particularly in fuel-importing economies seeking alternatives to coal and natural gas.

 

Japan’s Ammonia Co-Firing Strategy

 

Japan is advancing ammonia use at scale. JERA, the country’s largest power generator, recently secured a 15-year government subsidy to help cover the cost differential between ammonia and coal.

JERA plans to co-fire 20 percent ammonia at its 4.1 GW Hekinan thermal power station beginning in 2029 and has long-term ambitions to shift coal-fired power toward ammonia by the 2040s. The company has partnered with CF Industries and Mitsui & Co. on the $4 billion Blue Point low-carbon ammonia project in Louisiana. Ammonia produced there is expected to supply Japan’s power sector.

The Hekinan facility serves as an anchor in what Japanese policymakers describe as a developing low-carbon ammonia value chain.

Industrial Players Scaling Ammonia Cracking

 

Several major industrial firms are expanding ammonia-to-hydrogen capabilities. These include Topsoe, Air Liquide, thyssenkrupp Uhde, and Mitsubishi Heavy Industries.

Air Liquide recently started up a 30-ton-per-day industrial ammonia cracking pilot at the Port of Antwerp-Bruges in Belgium, demonstrating commercial-scale conversion capacity. The company has also strengthened its hydrogen footprint in Asia through acquisitions and integration of industrial gas assets.

 

Ammonia’s Role in the Hydrogen Economy

 

Ammonia-to-hydrogen systems offer a bridge between existing global infrastructure and future hydrogen demand. While renewable electricity, battery storage, and direct electrification remain central to decarbonization, ammonia provides a complementary pathway for sectors where energy density, transport logistics, and fuel flexibility are decisive.

The technology is advancing from pilot projects toward grid-connected deployments. If efficiency gains continue and policy frameworks remain supportive, ammonia cracking could become a critical component in decarbonizing power generation, maritime transport, and heavy industry.

As governments intensify climate commitments and carbon pricing mechanisms expand, ammonia’s evolution from fertilizer feedstock to clean energy carrier may become one of the more significant transitions within the hydrogen economy.
