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."

JGC Corporation demonstrates "world's first" carbon-free ammonia energy cycle

Trevor Brown January 04, 2019

In late 2018, JGC Corporation issued a press release to celebrate a "world's first" in ammonia energy, demonstrating at its pilot plant in Koriyama both "synthesis of ammonia with hydrogen produced through the electrolysis of water by renewable energy, and generation of electricity through gas turbines fueled by synthesized ammonia." By demonstrating the feasibility of using ammonia on both sides of the renewable energy equation -- first, producing green ammonia from intermittent renewable electricity and, second, combusting this carbon-free fuel for power generation -- the project demonstrates the role of ammonia in the "establishment of an energy chain ... that does not emit CO2 (CO2-free) from production to power generation."

New P2A2P Scheme Proposed in Norway

Stephen H. Crolius December 05, 2018

Svalbard, the Norwegian archipelago that sits far above the Arctic Circle, is being considered for the back end of an electricity-to-ammonia-to-electricity (P2A2P) scheme.  As reported in Norway's Teknisk Ukeblad (TU), the state-owned utility Statkraft has surfaced ammonia as one of four possible hydrogen-oriented solutions to meet Svalbard’s energy needs – and then short-listed it for further study.

Development of Technologies to Utilize Green Ammonia in the Energy Market - Update on Japan's SIP Energy Carriers

Trevor Brown November 30, 2018

At the recent NH3 Energy Implementation Conference in Pittsburgh, USA, the keynote speech was given by Shigeru Muraki, Program Director of Japanese government's SIP Energy Carriers project. Muraki is also Chairman of the Green Ammonia Consortium, which will assume responsibility for coordinating the development and deployment of ammonia energy technologies in Japan when the SIP concludes in April 2019. Given both these roles, Muraki was well placed to address not only the recent years of intense research and development in Japan, but also the near-term roadmap for commercial deployment of ammonia energy technologies.

Design Optimization of an Ammonia-Based Distributed Sustainable Agricultural Energy System

Small-scale, distributed production of ammonia better enables the use of renewable energy for its synthesis than the current paradigm of large-scale, centralized production. Pursuant to this idea, a small-scale Haber-Bosch process has been installed at the West Central Research and Outreach Center (WCROC) in Morris, MN [1] and there is ongoing work on an absorbent-enhanced process at the University of Minnesota [2], [3]. Using renewables to make ammonia would greatly improve the sustainability of fertilizer production, which currently accounts for 1% of total global energy consumption [4]. The promise of renewable-powered, distributed ammonia production for sustainability is in fact not…

Realisation of Large-Scale Green Ammonia Plants

Markus Will

The global ammonia production is nowadays mostly based on fossil energy carriers (natural gas, coal, naphtha, etc.). It consumes approximately 1.4% fossil energy carriers and releases more than 1.4% of global CO2 emissions. In order to continue the global transition from the fossil fuel and nuclear energy age to the renewable energy age, ammonia could play a key role. Beside the continued utilization for fertilizer industry, ammonia could become an energy and/or hydrogen carrier as well. thyssenkrupp Industrial Solutions (tkIS) developed a concept to establish Green Ammonia Plants as an alternative to conventional world-scale ammonia plants. As industry leader in…

Demonstration of CO2-Free Ammonia Synthesis Using Renewable Energy-Generated Hydrogen

In Japan, the government funding project SIP, Strategic Innovation Promotion Program, supports the research, development and demonstration of “Energy Carriers”. The concept of the “Energy Carriers” value chain is to produce hydrogen energy carriers overseas from fossil resources using CCS or renewable energy, and transport it to Japan for utilization as clean energy. The purpose of the program is to help realize a low-carbon society in Japan by using hydrogen. Among energy carriers, ammonia is the one of the most promising carriers, because of the ease of transportation as a liquid, higher hydrogen density, and proven technologies for commercial and…
