Committee on Climate Change sees role for ammonia enabling Hydrogen for a Low-Carbon Economy
Article

In the UK, an expansive report was published last month that examines the role of Hydrogen in a low-carbon economy. It considers ammonia's role in depth, both as a potential low-cost hydrogen carrier and as a direct fuel. As a hydrogen carrier, "converting hydrogen to ammonia as a means of transporting it over long distances would have lower costs than transporting it as hydrogen." And used directly, ammonia is "a hydrogen-rich liquid that could be used as an alternative or complementary fuel."

Ammonia Featured in Hydrogen Europe Roadmaps Report
Article

By definition, members of the ammonia energy community see ammonia as the preferred form of hydrogen in many applications.  Until recently, this view was not shared by most members of the hydrogen energy community.  Where there was awareness at all, ammonia was often seen as dangerous or irrelevant.  However, since the middle years of this decade a transition has been occurring.  Lack of awareness and wariness (let’s call this stage 1) is giving way to interest in and exploration of ammonia’s potential role in discrete applications (stage 2).  At some point, we may arrive at a third stage.  This will be characterized by the development of sustainable energy systems that have been cost-optimized with ammonia as a staple energy commodity.  In this scenario, elemental hydrogen will be the supporting actor that appears only in discrete contexts. Hydrogen, Enabling a Zero Emission Europe, Technology Roadmaps, a report released in September 2018 by the advocacy group Hydrogen Europe, perfectly exemplifies the stage 2 mindset.  Ammonia energy is discussed in a handful of instances as a narrow-scope expedient.  To be sure, the report implies, ammonia could be a part of the solution.  But it also might not pan out at all.

New P2A2P Scheme Proposed in Norway
Article

Svalbard, the Norwegian archipelago that sits far above the Arctic Circle, is being considered for the back end of an electricity-to-ammonia-to-electricity (P2A2P) scheme.  As reported in Norway's Teknisk Ukeblad (TU), the state-owned utility Statkraft has surfaced ammonia as one of four possible hydrogen-oriented solutions to meet Svalbard’s energy needs – and then short-listed it for further study.

Development of Technologies to Utilize Green Ammonia in the Energy Market - Update on Japan's SIP Energy Carriers
Article

At the recent NH3 Energy Implementation Conference in Pittsburgh, USA, the keynote speech was given by Shigeru Muraki, Program Director of Japanese government's SIP Energy Carriers project. Muraki is also Chairman of the Green Ammonia Consortium, which will assume responsibility for coordinating the development and deployment of ammonia energy technologies in Japan when the SIP concludes in April 2019. Given both these roles, Muraki was well placed to address not only the recent years of intense research and development in Japan, but also the near-term roadmap for commercial deployment of ammonia energy technologies.

CSIRO Partner Revealed for NH3-to-H2 Technology
Article

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.”

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

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
Presentation

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…
