Nel Hydrogen

For the latest episode of Ammonia Project Features, we explored the ongoing renewable ammonia project in Puertollano, Spain. Marc van Doorn (Grupo Fertiberia) and Imanol Arrizabalaga Prado (Nel ASA) discussed progress to date and technologies used at the first large-scale, electrolysis-based hydrogen facility in Europe, which is operated by renewable energy developer Iberdrola. We also considered what other pioneering projects are on the horizon, and how can electrolyzer manufacturers like Nel scale-up to meet growing demand?

The consortium developing the Skovgaard ammonia project has ordered an alkaline electrolyser system from Nel, bringing the 10 MW plant a step closer to reality. Skovgaard will be an important test case for hydrogen production directly from renewable energy, with no battery storage or firming to be used.

In other electrolyser news, German-based Sunfire and US-based Electric Hydrogen have received new funding to develop their technologies. Also in Germany, Siemens and Air Liquide will join forces to develop a GW-sized factory in Berlin, with 3 GW of PEM electrolyser units to be manufactured annually by 2025.

Welcome to the Ammonia Wrap: a summary of all the latest announcements, news items and publications about ammonia energy. There's so much news this edition that we're bringing you two, special Wrap articles. Our first focuses on ammonia production - both existing and new build plants. This week: InterContinental Energy to build 25 GW of green ammonia production in Oman, Cummins and KBR to collaborate on integrated green ammonia solutions, New green ammonia pilot plant for Minnesota, Stamicarbon launches new technology for sustainable fertilizer production in Kenya, Haldor Topsoe and Shchekinoazot to explore ammonia plant decarbonisation in Russia, 1 million tonne blue ammonia per year in Norway and Trammo announces off-take MoU for 2GW AustriaEnergy plant in Chile.

Welcome to the Ammonia Wrap: a summary of all the latest announcements, news items and publications about ammonia energy. This week: updates from India, the PROMETEO project - continuous hydrogen production by SOEC, Viridis Bulk Carriers - a new zero-emissions shipping company, Korean Register AiP for ammonia bunkering vessel, two green hydrogen import MoUs for the Port of Rotterdam and Haldor Topsoe and Nel team up to offer green fuel solutions.

Last week Ammonia Energy published “Europe!”, an article describing the European Commission’s Green Deal and the related appearance of national hydrogen strategies from several European countries. This week we have an article that describes another consequential European initiative that, while related to the Green Deal, is running on a distinct track: the Clean Hydrogen Alliance. Along the way a clear call to action has been sounded for the ammonia energy community.

Last month a group of researchers from the Technion Israel Institute of Technology published a paper, “Decoupled hydrogen and oxygen evolution by a two-step electrochemical–chemical cycle for efficient overall water splitting,” in the journal Nature Energy.  The key word in the title is “efficient.”  In a September 15 Technion press release, the researchers state that their technology “facilitates an unprecedented energetic efficiency of 98.7% in the production of hydrogen from water.”  Applied to the appropriate use case, the technology could lead to a major improvement in green ammonia’s ability to compete with brown ammonia and other low-carbon energy carriers.

This week, two Norwegian companies, fertilizer producer Yara and electrolyzer manufacturer Nel, announced an agreement to test Nel's "next generation" alkaline electrolyzer at an ammonia production site. The parties expect to begin operating a 5 MW prototype in 2022, feeding green hydrogen directly into Yara's 500,000 ton per year ammonia plant at Porsgrunn.

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.

The second annual European Conference on Sustainable Ammonia Solutions has announced its full program, spread over two days, May 17 and 18, 2018, at Rotterdam Zoo in the Netherlands. The international cadre of speakers, representing a dozen countries from across Europe as well as the US, Canada, Israel, and Japan, will describe global developments in ammonia energy from the perspectives of industry, academia, and government agencies.

On August 1, 2017 the Japan Government’s New Energy and Industrial Technology Development Organization (NEDO) announced that it will proceed with funding for the construction of a hydrogen production plant in Namie Township, about ten kilometers from the site of the Fukushima nuclear disaster.  The project’s budget is not mentioned, but the installation is projected to be “the largest scale in the world” -- in other words, a real bridge to the future and not a demonstration project.  The project no doubt has a variety of motivations, not least the symbolic value of a renewable hydrogen plant rising in the shadow of the Fukushima Daiichi nuclear station.  In economic terms, though, it appears to be a dead end.  This is unfortunate because a similarly conceived project based on ammonia could be a true bridge-building step that aligns with leading-edge developments elsewhere in the world.

The viability of producing ammonia using renewable energy was one of the recurring themes of the recent Power to Ammonia conference in Rotterdam. Specifically, what cost reductions or market mechanisms would be necessary so that renewable ammonia - produced using electrolytic hydrogen in a Haber-Bosch plant - would be competitive with normal, "brown" ammonia, made from fossil fuels. A number of major industry participants addressed this theme at the conference, including Yara and OCI Nitrogen, but it was the closing speech, from the International Energy Agency (IEA), that provided the key data to demonstrate that, because costs have already come down so far, renewable ammonia is cost-competitive in certain regions today.

This week, an important new voice joined the chorus of support for renewable ammonia and its potential use as an energy vector - the International Energy Agency (IEA). In his article, Producing industrial hydrogen from renewable energy, Cédric Philibert, Senior Energy Analyst at the IEA, identifies a major problem with the hydrogen economy: hydrogen is currently made from fossil fuels. But his argument for producing hydrogen from renewable energy leads almost inevitably to ammonia: "In some not-too-distant future, ammonia could be used on its own as a carbon-free fuel or as an energy carrier to store and transport energy conveniently."
