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.
This month, researchers at the University of Minnesota began successful field tests of their new ammonia engine, operating a heavy-duty tractor across farmland near Morris, MN, on a dual-fuel blend of 70% diesel and 30% ammonia.
This week, Hydrofuel Inc announced a commercial demonstration project to convert diesel gensets and transport trucks to run on ammonia fuel, with the conversion work and dual-fuel operations scheduled for a three year period.
The CAD $2 million (USD $1.5 million) project will take place at TFX International, in Toronto, and involves the conversion of four existing diesel-fueled assets: two stationary power generators and two transport trucks. These will be converted using Hydrofuel's "aftermarket multi-fuels engine retrofit systems," and they will thereafter be able to operate on a dual fuel basis.
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.
This week, Yara announced major progress toward producing "green ammonia" at its plant in Pilbara, Australia. Its new partner in this project is ENGIE, the global energy and services group, which last year made a major commitment to developing large-scale renewable hydrogen projects.
I first reported Yara's plans for a solar ammonia demonstration at its Pilbara plant in September 2017. This week's announcement means that the Pilbara project has moved to the next feasibility phase. However, major elements of the project have already been designed and built: during last year's scheduled turnaround for plant maintenance, the hydrogen piping tie-in was completed - meaning that the Haber-Bosch unit is ready to receive hydrogen directly, as soon as an electrolyzer has been built to supply it with renewable feedstock.
8 Rivers Capital, the developer of “the Allam Cycle, the only technology that will enable the world to meet all of its climate targets without having to pay more for electricity,” unveiled plans in November 2018 for a “billion-dollar clean energy production site” in New Zealand whose outputs are slated to include low-carbon ammonia.
That is a sentence with a lot of angles, and unpacking it will take some effort. So let’s start right in with the Allam Cycle.
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."
Dutch start-up Battolyser BV was today declared the winner of Industrial Energy Enlightenmentz 2018. The award was announced at the annual Industry & Energy event, held at the Brightlands Chemelot Campus in Geleen, which this year focused on the theme When Electrons Power Molecules.
At the NH3 Energy+ Topical Conference last month, Hans Vrijenhoef of Proton Ventures gave the opening presentation, co-authored by Fokko Mulder of TU Delft, in which he described the battolyser's robust combination battery and electrolyzer. He also mapped out Battolyser BV's technology development and investment pathway, beginning with the kW-scale pilot plant that is already underway and expected to be operational by Spring 2019, and a MW-scale, modular, containerized plant which should be complete by the end of 2020. Reaching a technology readiness level of TRL8, Battolyser BV then aims to increase industrial scale swiftly, demonstrating a 100 MW unit by 2025 and a 1 GW battolyser by 2030.

The International Maritime Organization issued its Initial GHG Strategy, committing the global shipping industry to emission reductions that cannot be achieved with carbon-based fuels. This single action is the regulatory trigger that unleashes a three-decade transition to carbon-free liquid fuels like ammonia. The target date for this 50% reduction in emissions is 2050 but, given the long economic life of ocean vessels, the transition must begin immediately.

IHI Corporation tested its 1 kW ammonia-fueled solid oxide fuel cell (SOFC) in Japan; Project Alkammonia concluded its work on cracked-ammonia-fed alkaline fuel cells (AFC) in the EU; the University of Delaware's project for low-temperature direct ammonia fuel cells (DAFC) continues with funding from the US Department of Energy's ARPA-E; and, in Israel, GenCell launched its commercial 4 kW ammonia-fed AFC with field demonstrations at up to 800 locations across Kenya.
