Mitsubishi Heavy Industries says that it has succeeded in producing 99% pure hydrogen by cracking ammonia using steam as the heating source. The production of hydrogen at pilot scale using the steam heating was conducted at the company’s pilot plant in the Nagasaki District Research & Innovation Centre, marking a world first. By contrast to technologies that use heat from burner combustion, MHI’s steam heating system operates at lower reaction temperatures, reducing operating costs. In addition, because a combustion furnace is not required, the system offers excellent features such as the potential for miniaturisation.

Air Liquide is developing a new ammonia cracking technology based on its proven steam methane reforming (including SMRX™ ) technology, which introduces a heat exchange concept to cut energy use, lower environmental impact, and potentially eliminate steam export. Leveraging extensive SMR design expertise, a robust R&D programme, and an industrialscale NH3 cracking pilot plant, it aims to rapidly mature all technology blocks and deliver safe, reliable, and customisable lowcarbon hydrogen solutions to meet growing demand.

thyssenkrupp Uhde and Uniper are entering into a strategic partnership to bring large-scale ammonia cracking technology to technological maturity. In the first phase, a demonstration plant with a capacity of 28 t/d of ammonia per day will be built at Uniper’s Gelsenkirchen-Scholven site in Germany. The plant will serve as the basis for the planned […]

KBR says that they have been awarded a second ammonia cracking technology contract by Hanwha Impact Corporation for its clean power generation facility in Korea. Under the terms of the agreement, KBR will provide technology licensing, proprietary engineering design and equipment, and services for a 214 t/d hydrogen facility. The plant will use KBR’s proprietary […]

Mitsubishi Heavy Industries is developing a low temperature ammonia cracking technology (HyMACS™ ) that leverages exhaust heat from existing sources, such as boilers, steam turbines, engines, and heating furnaces. This innovative approach, which also includes the development of more efficient membrane separation technology using molecular sieves for hydrogen purification, is designed to offer a more sustainable, reliable and cost-effective pathway towards hydrogen production.

Common risks of ammonia cracking as a new technology and how these risks can be recognised and mitigated by applying an innovative approach of the technology maturation process is described as seen through the eyes of an end user/investor. Addressing those risks is pivotal to enable end users to choose the best technology for their needs. Albert Lanser of Duiker Clean Technologies discusses some of these risks and how they have been addressed in its novel technology for producing the lowest levelised cost of hydrogen via its unique ammonia cracking process.

Large-scale ammonia cracking technology and catalysts will enable the full potential of ammonia to be realised as industries transition towards low carbon energy. In this feature we report on the current status of ammonia cracking processes and catalysts.

Ammonia has been recognised as an advantageous hydrogen and energy carrier. This article focuses on the use of ammonia as fuel in steam reformers and ammonia crackers in order to reduce or completely eliminate direct CO2 emissions. Ammonia combustion knowledge is especially important for ammonia crackers with respect to the recycling of unconverted ammonia. Air Liquide is constructing an industrial scale pilot plant in Antwerp, planned to be operational in 2024, that will be used to demonstrate ammonia cracking and combustion in a process furnace with a multiple burner configuration.

Highly efficient ammonia synthesis and subsequent cracking to hydrogen are key processes in the transition to the green hydrogen economy. Catalysts play an important role in the ammonia cracking process. Clariant offers both nickel and precious metal catalysts for this application and research on robust catalysts that allow lower temperatures for increased energy efficiency is ongoing.

New methods for low-carbon ammonia production are emerging, while project activity is also rising rapidly.
