Ammonia as a Grid-Supporting Energy Storage Solution

In the last 12 months ...
We have seen repeated enunciations of a compelling logic chain: electricity generated by wind-based and photovoltaic systems is manifesting ever-more competitive economics; the greater the share of electricity generated by intermittently active resources, the greater will be the need for complementary energy storage systems; chemical forms of “X” in the power-to-X (P2X) stored-electricity construct will surely have a role to play in long-term, large-scale energy storage; ammonia may be the most advantageous chemical for such storage.

Ammonia for Power: a literature review

"Ammonia for Power" is an open-access literature review that includes over 300 citations for recent and ongoing research in the use of ammonia in engines, fuel cells, and turbines, as well as providing references to decades of historical case studies and publications. The review, written by a consortium of ammonia energy experts from the University of Cardiff, University of Oxford, the UK's Science and Technology Facilities Council, and Tsinghua University in China, can be found in the November 2018 edition of Progress in Energy and Combustion Science.

Ammonia for Fuel Cells: a literature review

I wrote earlier today about a new literature review on "Ammonia for Power," published in November 2018. As a companion piece to that article, I'd like to highlight another open-access literature review, this one published a few years before we launched Ammonia Energy, which focuses completely on the (perhaps unexpectedly) broad subject of direct ammonia fuel cells. The mini-review, "Ammonia as a suitable fuel for fuel cells," was published in the August 2014 edition of Frontiers in Energy Research, written by Rong Lan and Shanwen Tao of the University of Strathclyde in the UK.

This Week in Hydrogen

September 10–14 gave us five remarkable events both evidencing and advancing the rise of hydrogen in transportation and energy. Any one of them would have made it a significant week; together they make a sea change.

Small-scale ammonia: where the economics work and the technology is ready

The movement toward small-scale ammonia is accelerating for two reasons. First, small ammonia plants are flexible. And, second, small ammonia plants are flexible.

They are feedstock-flexible, meaning that they can use the small quantities of low-value or stranded resources that are widely available at a local scale. This includes flared natural gas, landfill gas, or wind power.

And they are market-flexible, meaning that they can serve various local needs, selling products like fertilizer, energy storage, or fuel; or services like resource independence, price stability, or supply chain robustness.

While the scale of these plants is small, the impact of this technology is big. As industry-insider publication Nitrogen+Syngas explained in its last issue, "as ammonia production moves toward more sustainable and renewable feedstocks the ammonia market is facing a potentially radical change."

ITM Power, Sumitomo Enter Strategic Partnership

ITM Power and Sumitomo Corporation have entered into a strategic partnership “for the development of multi-megawatt projects in Japan based exclusively on ITM Power’s electrolyser products.”  The two companies will also look for collaborative opportunities outside Japan.  In a July 9 press release, ITM refers to the two companies’ shared vision for “the use of hydrogen to decarbonise heat, transport and industrial processes” as the foundation for the arrangement.

DNV GL predicts carbon-neutral fuels, including ammonia, to surpass oil for shipping by 2050

This week, DNV GL published its annual Energy Transition Outlook, providing a long-term forecast for global energy production and consumption, and including a dedicated report describing its Maritime Forecast to 2050. This is the first forecast from a major classification society explicitly to evaluate ammonia as a maritime fuel.

By 2050, DNV GL predicts that 39% of the global shipping energy mix will consist of "carbon-neutral fuels," a category that include ammonia, hydrogen, biofuels, and other fuels produced from electricity. By 2050, these fuels will therefore have gained greater market share than oil, LNG, and battery-electric. If ammonia succeeds as the carbon-neutral fuel of choice in the shipping sector, this new demand will be roughly equivalent to 200 million tons of ammonia per year, more than today's total global production.

Ammonia Energy Coming on Like Gangbusters in Australia

NH3FA.Oz, the Australian chapter of the NH3 Fuel Association, held a meeting on August 30 in approximate observance of its one-year anniversary.  John Mott, one of the founders of NH3FA.Oz and a member of the NH3 Fuel Association’s Advisory Board, reported that more than two dozen stakeholders from academia, industry, and the public sector participated.  The meeting came on the heels of the rapid-fire release of three significant reports, and preceded by a week the announcement of an important set of research grants.  The meeting, the reports, and the announcement all made clear that ammonia  is fast becoming a fixture in Australian energy policy.

Science Publishes “Net Zero Emissions” Paper, NH3 Seen in Prominent Role

Ammonia energy received prominent mention in a review article published in the June 29, 2018 edition of Science magazine.  Science is the flagship publication of the American Association for the Advancement of Science.  The paper, whose main body is almost 7,000 words long, is entitled “Net zero emissions energy systems.”  While the paper's overall mission is to examine “the special challenges associated with an energy system that does not add any CO2 to the atmosphere,” the specific concerns that set it in motion relate to the idea that “energy services essential to modern civilization entail emissions that are likely to be more difficult to fully eliminate.”  The paper is a detailed investigation of technological solutions that can be applied in these areas.  Ammonia is highlighted as an “energy-dense liquid fuel” that could meet the needs of long-distance transportation services including aviation, long-distance trucking, and shipping.

Siemens Gamesa investigating green ammonia pilot plant in Denmark

Another week, another green ammonia pilot plant.

Siemens Gamesa, the world's largest wind turbine manufacturer (by installed capacity), has announced a partnership with local climate innovation fund Energifonden Skive to investigate the production of ammonia from wind power at an eco-industrial hub in Denmark's "Green Tech Valley." The announcement describes "an agreement to jointly explore eco-friendly ammonia production as a way to store surplus electricity from wind turbines. The goal: a pilot plant at GreenLab Skive."
