Energy Storage through Electrochemical Ammonia Synthesis Using Proton-Conducting Ceramics

Neal P. SullivanLiangzhu ZhuChuancheng DuanRyan O'HayreMax PisciottaLong LeCarolina Herradon HernandezMichelle ButlerCanan KarakayaRobert J. KeeFred JahnkeHossein Ghezel-Ayagh

In this presentation, we provide an overview of an ambitious project to store renewable energy through electrochemical synthesis of ammonia. The joint project between the Colorado School of Mines (Golden, CO) and FuelCell Energy, Inc. (Danbury, CT) is supported through the U.S. Department of Energy ARPA-E ‘REFUEL’ program. The research and development team seeks to harness the unique properties of proton-conducting ceramics to activate chemical and electrochemical reactions for efficient and cost-effective synthesis of ammonia. The system concept is shown in Figure 1; renewable electricity is used to drive electrolysis of the H2O feedstock to form hydrogen. This electrochemically produced…

Solid Oxide Technology for Ammonia Production and Use

John Bøgild Hansen

The presentation will outline a 4 million € project funded by the Danish Energy Agency. The project is coordinated by Haldor Topsøe A/S and the partners are Vestas Wind Power, Ørsted, Energinet, Equinor, DTU Energy Conversion, and Aarhus University. The purpose of the project is to demonstrate a novel process for generation of ammonia synthesis gas without an air separation unit by means of Solid Oxide Electrolyzer Cells as well as using ammonia as a fuel for Solid Oxide Fuel Cells. The synthesis gas generation plant will be a 50 kW unit. The SOFC unit test will be carried out…

Israeli Group Develops New Electrolysis Technology

Stephen H. Crolius October 08, 2019

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.

Yara and Nel collaborate to reduce electrolyzer costs; announce green ammonia pilot in Norway by 2022

Trevor Brown August 23, 2019

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.

High efficiency ammonia synthesis systems

John Bøgild Hansen

Haldor Topsøe A/S has developed a new technology for generation of ammonia synthesis gas via Solid Oxide electrolysis, which eliminates an air separation unit and has 20-30 % lower power consumption than traditional electrolysis based processes. The concept will be demonstrated in a 50 kW unit along with test of ammonia as fuel for Solid Oxide Fuel Cells. The partners in the project are: Vestas, Ørsted, Energinet, Aarhus University and DTU, and it is sponsored by the Danish Energy Development Programme.

New Video Summarizes SIP Energy Carriers Accomplishments

Stephen H. Crolius April 18, 2019

ANNOUNCEMENT: The Japanese Government’s Cabinet Office and the Japan Science and Technology Agency have released an English-language video that summarizes the accomplishments of the Cross-Ministerial Strategic Innovation Promotion Program’s Energy Carriers initiative.  The release coincides with the end-of-March conclusion of Energy Carriers’ work, and anticipates this month’s formal activation of the Green Ammonia Consortium.

Green ammonia: Haldor Topsoe's solid oxide electrolyzer

Trevor Brown March 29, 2019

Haldor Topsoe has greatly improved the near-term prospects for green ammonia by announcing a demonstration of its next-generation ammonia synthesis plant. This new technology uses a solid oxide electrolysis cell to make synthesis gas (hydrogen and nitrogen), which feeds Haldor Topsoe's existing technology: the Haber-Bosch plant. The product is ammonia, made from air, water, and renewable electricity. The "SOC4NH3" project was recently awarded funds from the Danish Energy Agency, allowing Haldor Topsoe to demonstrate the system with its academic partners, and to deliver a feasibility study for a small industrial-scale green ammonia pilot plant, which it hopes to build by 2025. There are two dimensions to this technology that make it so important: its credibility and its efficiency.

Mission Possible: decarbonizing ammonia

Trevor Brown January 18, 2019

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."
