Ammonia Figures Prominently in IEA Hydrogen Report

Two weeks ago the International Energy Agency released The Future of Hydrogen, a 203-page report that “provides an extensive and independent assessment of hydrogen that lays out where things stand now; the ways in which hydrogen can help to achieve a clean, secure and affordable energy future; and how we can go about realising its potential.” In this, the second part of a two-part article, the report's extensive treatment of ammonia is considered.

IEA Releases Forward-Looking Hydrogen Report

Last week the International Energy Agency released The Future of Hydrogen, a 203-page report that “provides an extensive and independent assessment of hydrogen that lays out where things stand now; the ways in which hydrogen can help to achieve a clean, secure and affordable energy future; and how we can go about realising its potential.” In this, the first part of a two-part article, the report's overall strengths are considered.  The second part will focus on the report's discussion of ammonia as a contributor to the emerging hydrogen economy.

NH3 vs. MCH: Energy Efficiency of Hydrogen Carriers Compared

Volume 174 of the journal Energy, published on May 1, 2019, includes a paper by Shin’ya Obara, Professor in the Department of Electrical and Electronic Engineering at the Kitami Institute of Technology in Japan, that should be of interest to hydrogen advocates everywhere.  The paper, "Energy and exergy flows of a hydrogen supply chain with truck transportation of ammonia or methyl cyclohexane," concludes that a hydrogen supply chain based on ammonia has better energy efficiency than one based on methyl cyclohexane (MCH).

METI Releases Major Revision to Hydrogen Roadmap

Japan’s Ministry of Economy, Trade and Industry (METI) announced on March 12 that it had released a “major revision” to the country’s Hydrogen and Fuel Cell Strategy Roadmap.  The Roadmap was first formulated in 2014 to “secure the goals set forth in the Basic Hydrogen Strategy and the 5th Basic Energy Plan for the realization of a hydrogen society.”  The Roadmap’s last revision in 2016 predates new editions of the foundation documents that were released in December 2017 and July 2018, respectively.

Ammonia as an environmentally benign energy carrier for the fast growth of China

NEWS BRIEF: A research paper was published this week by researchers from Xiamen Univeristy in China, which "proposes a scheme for an ammonia-based energy storage system in which ammonia, an environmentally benign hydrogen carrier, is expected to [resolve] the conflicts of renewable energy supply and consumption in China."

Ammonia’s Role in the Hydrogen Society

Last month I had the opportunity to reflect on “Ammonia’s Role in the Hydrogen Society.”  This was the title of a speech I gave at the Ammonia Energy International Workshop in Tokyo.  The Workshop was held on January 25 by the Energy Carriers initiative of the Japanese Government’s Strategic Innovation Promotion Program (SIP) as it moves toward its terminal date of March 31, and as the Green Ammonia Consortium, which grew out of the Energy Carriers program, prepares for its official launch in the same time frame.  The key takeaways from my speech are that ammonia is widely seen as a contributor to the viability of hydrogen energy, but the extent of its potential role is not appreciated.

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

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

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

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.

CSIRO Partner Revealed for NH3-to-H2 Technology

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.”
