Literature review: Electrochemical Ammonia Synthesis and Ammonia Fuel Cells

The journal Advanced Materials recently published an article that reviews electrochemical ammonia technologies for both synthesis and power generation. In addition to presenting a range of technologies under development, the authors, based at the University of Delaware, present "perspectives in the technical challenges and possible remedies."

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."

EPRI Releases Ammonia Energy Report

Last month the Electric Power Research Institute (EPRI) released Renewable Ammonia Generation, Transport, and Utilization in the Transportation Sector, the organization’s first public treatment of ammonia energy.  The report is positioned as a communique from the cutting edge – a “Technology Insights Brief” from EPRI’s “Innovation Scouts” – and, bracingly, manages to be both brief and comprehensive.  Within its format, it does an excellent job of conveying the positive case for ammonia energy and the R&D that will allow it to reach its potential.

IEA Analysis: Green Chinese P2A Could Compete with Brown NH3

The IEA has developed a rigorous economic model to examine the proposition that resource intermittency can be managed by siting hydrogen facilities where variable renewable energy (VRE) resources have complementary daily and seasonal production profiles. Last month, IEA Senior Analyst Cédric Philibert shared modeling results from selected sites in China with an audience at the Energy Research Institute in Beijing.  The exercise offers a first quantitative look at two important questions.  First, what is the economic impact of "VRE stacking"?  And second, what is the relative cost position of ammonia produced via a stacking approach?

Fuels Without Carbon: Prospects and the Pathway Forward for Zero-Carbon Hydrogen and Ammonia Fuels

A new report from CATF, Fuels Without Carbon: Prospects and the Pathway Forward for Zero-Carbon Hydrogen and Ammonia Fuels, explores how a massive scale-up in the production and use of zero-carbon hydrogen and ammonia might help decarbonize segments of the power sector, the industrial sector, and the transportation sector (both marine and ground). Fuels Without Carbon looks at how the availability of zero-carbon hydrogen and ammonia fuels could help address several vexing climate-energy challenges, and it examines the steps that need to be taken to fully understand and address the safety and environmental risks associated with the two chemicals. Fuels Without Carbon also identifies several public and private sectors initiatives — including a few being pursued by CATF — for analyzing the opportunities and challenges associated with hydrogen and ammonia fuel, educating stakeholders about the potential benefits and risks, designing and advocating for appropriately supportive policies, and engaging with key power and mobility companies.

Ammonia plant revamp to decarbonize: Yara Pilbara

This week, Yara announced major progress toward producing "green ammonia" at its plant in Pilbara, Australia. Its new partner in this project is ENGIE, the global energy and services group, which last year made a major commitment to developing large-scale renewable hydrogen projects.

I first reported Yara's plans for a solar ammonia demonstration at its Pilbara plant in September 2017. This week's announcement means that the Pilbara project has moved to the next feasibility phase. However, major elements of the project have already been designed and built: during last year's scheduled turnaround for plant maintenance, the hydrogen piping tie-in was completed - meaning that the Haber-Bosch unit is ready to receive hydrogen directly, as soon as an electrolyzer has been built to supply it with renewable feedstock.

Hydrogen and Ammonia Discussed in Australian Energy Storage Report

The Australian report Comparison of dispatchable renewable electricity options does the very useful service of quantifying the energy storage landscape in dollars and cents.  It reaches many interesting conclusions, not the least of which is that hydrogen, and by explicit extension, ammonia, is the key option for long-cycle storage.  And while the study’s focus is Australia, “with costs in AUD and based on Australian conditions,” its lead author says that “much of the information and many of its findings are expected to hold independent of jurisdiction.”

Mission Possible: decarbonizing ammonia

Mission Possible, a major report published at the end of 2018, concludes that decarbonizing ammonia production by 2050 is both technically and economically feasible. Among its 172 pages of assumptions, analysis, and explanation, Mission Possible examines production pathways and markets for green ammonia and its derivative green nitrogen fertilizers. It addresses the relatively straightforward issue of how to replace fossil feedstocks with renewable hydrogen for ammonia synthesis, as well as the more complex question of how to source or supplant the carbon dioxide molecules contained in urea, the most common nitrogen fertilizer.

The report's economic conclusions will not surprise anyone involved in ammonia production or politics. Yes, green ammonia is currently more expensive than fossil ammonia, although it won't be for long. And no, "none of the increases in end-consumer prices are sufficiently large to be an argument against forceful policies to drive decarbonization."

Mission Possible: a roadmap for net-zero emissions in the heavy industry and heavy-duty transport sectors

Mission Possible, a recent report published by the Energy Transitions Commission, presents an extremely detailed roadmap for "Reaching net-zero carbon emissions from harder-to-abate sectors by mid-century." The report is designed to support the targets of the Paris Agreement by sending "a clear signal to policymakers, investors and businesses: full decarbonization is possible, making ambitious climate objectives achievable."

Ammonia is one of the crucial solutions that make Mission Possible possible. In its 172-pages, the report details the technologies and the economics behind decarbonizing ammonia, the "likely" adoption of ammonia as the carbon-free fuel of choice for long-distance shipping, and the "key role" ammonia will play in enabling international trade in renewable power.
