Gigastack Phase 2 Receives Funding in the UK

Stephen H. Crolius February 20, 2020

Earlier this week the United Kingdom’s Department for Business, Energy & Industrial Strategy (BEIS) announced that a group led by ITM Power has been awarded GBP 7.5 million (USD $9.7 million) for the second phase of a renewable hydrogen project dubbed “Gigastack.” According to the BEIS announcement, “Gigastack will demonstrate the delivery of bulk, low-cost and zero-carbon hydrogen through ITM Power’s gigawatt scale polymer electrolyte membrane (PEM) electrolysers . . .” with the goal of “dramatically reduc[ing] the cost of electrolytic hydrogen.” The hydrogen produced will be used for petroleum refining, although the project partners have their eyes on opportunities that go well beyond desulfurization of oil.

Arranged launches DualTower website, expands to DualSolar

Trevor Brown December 12, 2019

MEMBER NEWS: AEA Member Arranged BVBA has launched a new website for its green ammonia concept, the DualTower. The new site discloses a series of updates on the technology since we first wrote about this project in early 2018, and it also expands the concept in a new direction, introducing the DualSolar.

Comparative Technoeconomic Analysis of Conventional and Absorbent-Enhanced Ammonia Synthesis

Matthew Palys Alon McCormick Edward Cussler Prodromos Daoutidis

Ammonia is the second-most produced synthetic chemical and the main precursor for nitrogen-based fertilizer. In 2015, 160 million tons were produced globally, and global demand is expected to grow 1.5% annually until 2050 [1]. However, traditional ammonia production uses natural gas or coal as its hydrogen source, and as a result, is also responsible for more than 1% of global GHG emissions and 5% of global natural gas consumption [2]. Clearly, a more sustainable ammonia production scheme is needed. One such alternative is obtain hydrogen from electrolysis powered by wind- or solar-derived electricity. It has been proposed to perform this…

Green Ammonia Plants in Chile, Australia, New Zealand

Trevor Brown October 04, 2019

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

Stephen H. Crolius June 13, 2019

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

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.

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.

Ammonia Absorption and Desorption in Ammines

Collin Smith Mahdi Malmali Chen-Yu Liu Alon McCormick Edward Cussler

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

Trevor Brown October 11, 2018

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.
