Hyundai joins Fortescue and CSIRO to “fast track” ammonia to high-purity hydrogen system

Fortescue recently announced that it has signed a memorandum of understanding (MOU) with Hyundai Motor Company and CSIRO for the “development and future commercialisation” of its metal membrane technology. This technology, which produces high-purity compressed hydrogen from liquid ammonia, was demonstrated in 2018. It enables PEM fuel cell vehicles to refuel using hydrogen that is generated on demand from ammonia. At scale, this technology could enable an ammonia-based hydrogen production, storage, and distribution infrastructure, lowering the barriers to implementation of a national network of hydrogen filling stations. Now, “Hyundai will seek to demonstrate the viability of the technology for renewable hydrogen production and vehicle fuelling in Korea.”

Engie, Siemens, Ecuity, and STFC publish Feasibility of Ammonia-to-Hydrogen

The UK’s Department for Business, Energy and Industrial Strategy (BEIS) recently published the feasibility study for its Ammonia to Green Hydrogen Project. This studies the techno-economic feasibility of importing green ammonia in order to supply large volumes of high-purity low-carbon hydrogen in the UK. The project has been designed and delivered by a heavyweight consortium of ENGIE, Siemens, Ecuity Consulting, and the UK’s STFC. The feasibility study, which is publicly available, represents the conclusion of Phase One of this project. Phase Two is demonstration: “to raise the TRL of a lithium imide based ammonia cracker from 4 to 6/7,” meaning that the technology is ready for deployment.

Hydrogen Filling Stations: techno-economic analysis of on-site ammonia reforming and H2 purification

This month, a team of researchers from Fuzhou University in Fujian, China, published a new paper in the journal Sustainable Energy & Fuels that provides a “Techno-economic analysis and comprehensive optimization of an on-site hydrogen refuelling station system using ammonia.” The study concludes that “the H2 production cost of the NH3-fed on-site hydrogen refuelling station was at least 15% lower than other carbon-free routes (such as electrolysis, solar thermolysis, photo-electrolysis, etc.), and comparable to that of a methane steam reforming system with carbon capture and storage.”

Development of a Highly Efficient COx-Free Ammonia Dehydrogenation System for Fuel Cell Applications

The shortage of fossil fuels and emission of carbon dioxide to the environment have attracted an interest in discovering renewable energy as the next generation energy source. Owing to its intermittent and unpredictable nature, however, excess renewable energy needs to be stored and reused on demand. In the regard, hydrogen, which possesses a high gravimetric energy density and carbon free combustion process, has been extensively researched as a promising renewable energy carrier. However, the distribution and storage of hydrogen still raise important challenges due to the low volumetric energy density of hydrogen for its wide utilization. Currently, gaseous hydrogen transportation…

Ammonia As a Hydrogen Carrier for PEM Fuel Cells

Ammonia (NH3) is easily liquefied by compression at 1 MPa and 25°C, and has highest volumetric hydrogen density of 10.7 kg H2 /100L. It has high gravimetric hydrogen density of 17.8 wt%. The heat of formation of NH3 is about 1/10 of combustion heat of hydrogen. NH3 has advantages as a hydrogen carrier for fuel cell vehicles (FCVs). ISO 14687-2:2012 specifies the quality characteristics of hydrogen fuel. The maximum concentration of NH3 and N2 for the FCVs is 0.1ppm and 100 ppm, respectively. The minimum H2 purity is 99.97%. We need component technologies to produce high-purity hydrogen from ammonia, together…

Catalytic Membrane Reactors for Efficient Delivery of High Purity Hydrogen from Ammonia Decomposition

The deployment of fuel cell electric vehicles is constrained by the paucity of hydrogen fueling stations and price, which is dominated by the costs of hydrogen storage and transportation. With more hydrogen per volume than liquid H2 and an extensive distribution infrastructure in place, ammonia is a promising vector for efficient hydrogen distribution. In this talk we describe the development of innovative catalytic membrane reactor (CMR) technology for the delivery of high purity H2 from ammonia cracking. The CMR integrates state-of-the art catalysts with thin metal membranes in an innovative design. Conventionally, the catalyst is supplied to CMRs in the…

Ammonia-to-Hydrogen System for FCEV Refuelling

Ammonia can play a significant role in fuelling the world’s growing fuel cell electric vehicle (FCEV) fleet through technologies which allow the decomposition of NH3, and subsequent extraction and purification of H2. CSIRO has recently demonstrated a pilot-scale ammonia-to-hydrogen system, incorporating an ammonia decomposition stage with a subsequent membrane-based hydrogen purification stage, at a rate of several kilograms of H2 per day. Through partnerships with an industrial gas producer and two FCEV manufacturers, the resulting H2 has been compressed and dispensed into FCEVs. System design, materials, performance and strategies for scale-up and demonstration will be discussed.
