Ammonia Covered in Forbes.com Power-to-X Review

Last week, Forbes.com published Power-To-X In The German Experience: Another In The List Of Growing Energy Transition Strategies.  The article in effect nominates ammonia as a singularly promising up-and-comer in the field of the alternative energy vectors.  Such an endorsement is heartening, but the article is notable as much for who is delivering the message – and the fact of its delivery under the Forbes masthead – as for what the message is.

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).

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?

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.”

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.

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.

Science Publishes Feature Article on Ammonia Energy

On July 13, Science magazine, the flagship publication of the American Association for the Advancement of Science (AAAS), published a 2,800-word “feature article" on ammonia energy. The article, headlined, “Liquid sunshine: Ammonia made from sun, air, and water could turn Australia into a renewable energy superpower,” is uniformly open-minded and upbeat.  Its opening section ends with a quote from Monash University Professor of Physics and Chemistry Doug MacFarlane; “’Liquid ammonia is liquid energy,’ he says. ‘It's the sustainable technology we need.’”

MacFarlane helped launch the Australian chapter of the NH3 Fuel Association.

Nel Stakes a Claim on Another Key Frontier of Hydrogen Implementation

On June 28, Norwegian hydrogen company Nel ASA issued a press release announcing that the company will supply “448 electrolyzers and associated fueling equipment to Nikola Motor Company as part of Nikola’s development of a hydrogen station infrastructure in the U.S. for truck and passenger vehicles.”  The Nikola-Nel arrangement is a globally significant step in the process of implementing a full-scale hydrogen energy economy.  And although its approach for supplying green energy to hydrogen fueling stations does not involve ammonia, it seems likely it will ultimately help make the case for ammonia as an economically advantaged option.

Battolyser Attracts Grant Funding, Corporate Support

The kernel of the story is this: Battolyser B.V. is taking a step forward with the battolyser, its eponymous energy storage technology.  On June 12, Battolyser’s joint venture partners Delft University of Technology (TU Delft) and Proton Ventures announced that they had secured a €480,000 grant from Waddenfonds, a Dutch public-sector funding agency, to build a 15 kW/60 kWh version of the battolyser.  The installation will take place at Nuon’s Magnum generating station at Eemshaven in the Netherlands.  The move makes tangible the vision of the battolyser as an integral part of an energy supply system with a robust quota of renewably generated electricity.

The battolyser is a battery that stores electricity in the conventional galvanic manner until it is fully charged.  At that point, the device uses any additional electricity supplied for the electrolysis of water and evolution of hydrogen.  If the device is integrated with hydrogen buffer storage and an ammonia production train, the result will be a versatile and highly scalable energy storage system that can provide highly responsive grid support on all time scales from seconds to months.  (Ammonia Energy last posted on the battolyser on March 1, 2018.)
