Material Discovery and Investigation of Novel Y Containing Ru Catalysts for Low Temperature Ammonia Decomposition

Katie McCulloughTravis WilliamsJochen Lauterbach

Liquid ammonia can be used as an alternative hydrogen carrier and can be decomposed over catalysts to create a high purity hydrogen stream for fuel cell applications. Ammonia decomposition is typically catalyzed using supported ruthenium catalysts. Current ruthenium catalysts are expensive and often require reaction temperatures of 650 °C to attain complete conversion [1]. For the hydrogen produced from ammonia decomposition to be efficiently used in proton exchange membrane fuel cells, operating temperatures need to be considerably lowered and effluent concentrations of ammonia need to be minimized to avoid poisoning of the membrane [2]. Therefore, it is of interest to…

Carbon-Free H2 Production from NH3 Triggered at Ambient Temperature with Oxide Supported Ru Catalysts

Katsutoshi NagaokaKatsutoshi SatoYuta Ogura

Hydrogen produced from renewable energy has received a lot of attentions as a clean energy and development of a hydrogen storage and transportation system using hydrogen carrier has been greatly demanded. Among different kinds of hydrogen carrier, NH3 is regarded as one of the promising candidates, due to high energy density, high hydrogen capacity, and ease of liquification at room temperature. Furthermore, a carbon-free hydrogen storage and transportation system could be realized by using NH3 as hydrogen carrier. In this system, hydrogen produced from NH3 is used in engines, fuel cells, and turbines. However, use of NH3 as a hydrogen…

Engie, Siemens, STFC, and Ecuity awarded funding for green ammonia-to-hydrogen in UK

Trevor Brown September 06, 2019

Last week, the UK Department for Business, Energy and Industrial Strategy (BEIS) announced a "£390 million government investment to reduce emissions from industry," with a focus on low-carbon hydrogen supply and clean steel production. As part of this investment, a consortium led by Ecuity Consulting that includes Siemens, Engie, and the Science & Technology Facilities Council (STFC), has been awarded £249,000 to perform "valuable research on the role of ammonia in the delivery of low cost bulk hydrogen for use in the UK energy system."

GenCell A5 update: hydrogen power from ammonia fuel cells ("The Next Big Thing in Energy Production")

Trevor Brown July 18, 2019

GenCell Energy, an Israeli technology company, recently announced a research collaboration with Fraunhofer UMSICHT, a German research institute, that will deliver a "scale-up of the catalyst synthesis process" for cracking ammonia. This will enable GenCell "to produce large quantities of a novel inexpensive catalyst for generation of hydrogen from ammonia."

CSIRO Partner Revealed for NH3-to-H2 Technology

Stephen H. Crolius November 28, 2018

Last week Australia’s Commonwealth Scientific and Industrial Research Organisation (CSIRO) announced the formation of a partnership that will support commercialization of CSIRO’s high-purity ammonia-to-hydrogen conversion technology.  Michael Dolan, Principal Research Scientist for the ammonia-to-hydrogen project, had signaled such a development on the occasion of the technology’s first public demonstration in August 2018, saying in a contemporaneous Ammonia Energy post that the identity of “a major industrial partner” would be revealed shortly. The partner turns out to be Fortescue Metals Group (FMG).  A November 22 article in Business Insider Australia states that the company will invest “[AUD]$19.1 million [USD$13.8] in technology developed by the CSIRO to make hydrogen vehicles viable in a potential gamechanger for the transport industry.”

Ammonia-to-Hydrogen System for FCEV Refuelling

Michael Dolan

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.
