Green Ammonia Plants in Chile, Australia, New Zealand
Article

Green ammonia plants are being announced quicker than I can report. Here is a summary of four new projects that propose to use electrolyzers, fed by renewable power, to produce hydrogen for ammonia production. These are big companies, operating in regions with excellent renewable resources, making significant investments in their future. In Chile, it is Enaex, a major ammonium nitrate manufacturer, supplying explosives to the mining industry. In Australia, it is Incitec Pivot, "the second largest supplier of explosives products and services in the world," and Wesfarmers, "the largest Australian company by revenue," according to Wikipedia. In New Zealand, it is Ballance-Agri Nutrients, a big farmers' co-operative and the country's sole fertilizer producer. Each aims to make its business "future-proof." The transition from fossil ammonia to renewable ammonia is underway.

New Coalition Plans to Build Offshore Green Fueling Hubs
Article

Last week Wärtsilä, the Finnish engine and energy equipment manufacturer, unveiled a concept for producing and distributing low-carbon maritime fuels from purpose-built facilities in the waters off northern Europe.  Dubbed Zero Emission Energy Distribution at Sea (ZEEDS), the initiative is intended to help meet the International Maritime Organization’s target of halving the shipping sector's carbon dioxide emissions by 2050.  And although Wärtsilä’s press release on June 3 mentions only “clean fuels,” the headline used by logistics-sector publisher Freight Week for their June 5 story is “Offshore fuel hubs to supply green ammonia for zero-emission future.”

Green ammonia: Haldor Topsoe's solid oxide electrolyzer
Article

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.

New P2A2P Scheme Proposed in Norway
Article

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.

Ammonia Absorption and Desorption in Ammines
Presentation

While adsorption onto solids is a common separation process, absorption into solids is much less often used. The reason is that absorption is usually assumed ineffective because it includes very slow solute diffusion into the solid. An exception may be the separation of ammonia from nitrogen and hydrogen using ammines, especially at temperatures close to those used in ammonia synthesis. There, ammonia can be selectively absorbed by calcium chloride; nitrogen and hydrogen are not absorbed. The kinetics of ammonia release seem to be diffusion controlled. The kinetics of absorption are consistent with a first order reaction and diffusion in series,…

Green Ammonia Plants, Commercially Available Today
Article

In the last 12 months ... Green ammonia pilot plants began operations in the UK and Japan, and new demonstration plants were announced in Australia, Denmark, Morocco, and the Netherlands (more, yet to be announced, are in development). Fertilizer company CEOs spoke about how green ammonia fits their corporate strategy. And all four of the global licensors of ammonia technology made it abundantly clear that they are ready and willing to build your green ammonia plant, today.

Ammonia as a Grid-Supporting Energy Storage Solution
Article

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.

Siemens Gamesa investigating green ammonia pilot plant in Denmark
Article

Another week, another green ammonia pilot plant. Siemens Gamesa, the world's largest wind turbine manufacturer (by installed capacity), has announced a partnership with local climate innovation fund Energifonden Skive to investigate the production of ammonia from wind power at an eco-industrial hub in Denmark's "Green Tech Valley." The announcement describes "an agreement to jointly explore eco-friendly ammonia production as a way to store surplus electricity from wind turbines. The goal: a pilot plant at GreenLab Skive."

Green ammonia demonstration plants now operational, in Oxford and Fukushima
Article

Two new pilot projects for producing "green ammonia" from renewable electricity are now up and running and successfully producing ammonia. In April 2018, the Ammonia Manufacturing Pilot Plant for Renewable Energy started up at the Fukushima Renewable Energy Institute - AIST (FREA) in Japan. Earlier this week, Siemens launched operations at its Green Ammonia Demonstrator, at the Rutherford Appleton Laboratory outside Oxford in the UK. The commercial product coming out of these plants is not ammonia, however, it is knowledge. While both the FREA and Siemens plants are of similar scale, with respective ammonia capacities of 20 and 30 kg per day, they have very different objectives. At FREA, the pilot project supports catalyst development with the goal of enabling efficient low-pressure, low-temperature ammonia synthesis. At Siemens, the pilot will provide insights into the business case for ammonia as a market-flexible energy storage vector.
