This week, the government of South Australia announced a "globally-significant demonstrator project," to be built by the hydrogen infrastructure company Hydrogen Utility (H2U). The renewable hydrogen power plant will cost AUD$117.5 million ($95 million USD), and will be built by ThyssenKrupp Industrial Solutions with construction beginning in 2019.
The plant will comprise a 15 MW electrolyzer system, to produce the hydrogen, and two technologies for converting the hydrogen back into electricity: a 10MW gas turbine and 5MW fuel cell. The plant will also include a small but significant ammonia plant, making it "among the first ever commercial facilities to produce distributed ammonia from intermittent renewable resources."
The list of investment drivers for building new ammonia plants in the US over the last few years was short, beginning and ending with cheap natural gas. Markets change, however, and the investment drivers for the next generation of new ammonia plants might include low cost electrolyzers, low cost renewable power, carbon taxes, and global demand for ammonia as a carbon-free energy vector.
For this to make sense, however, ammonia needs to be produced without fossil fuel inputs. This is perfectly possible using Haber-Bosch technology with electrolyzers, but today's wind and solar power plants exist on a smaller scale than could support a standard (very big) Haber-Bosch plant. So, to produce renewable ammonia, small-scale ammonia production is essential.
This time series chart shows the capital intensity of today’s ammonia plants. Together, the data illustrate competitive advantages of alternative investment strategies, and demonstrate a shift away from the prior trend toward (and received wisdom of) monolithic mega-plants that rely on a natural gas feedstock.
This series of articles on the future of ammonia synthesis began with a report on the NH3 Energy+ conference presentation by Grigorii Soloveichik, Program Director at the US Department of Energy's ARPA-E, who categorized the technologies as being either improvements on Haber-Bosch or electrochemical (with exceptions).
ARPA-E invests in "transformational, high-risk, early-stage research," and recently began funding ammonia synthesis technologies, not to make renewable fertilizer but to produce "energy-dense zero-carbon liquid fuel." This article will introduce the six electrochemical technologies currently in development with funding from ARPA-E.
This morning in Beijing, China, the International Energy Agency (IEA) launched a major new report with a compelling vision for ammonia's role as a "hydrogen-rich chemical" in a low-carbon economy.
Green ammonia would be used by industry "as feedstock, process agent, and fuel," and its production from electrolytic hydrogen would spur the commercial deployment of "several terawatts" of new renewable power. These terawatts would be for industrial markets, additional to all prior estimates of renewable deployment required to serve electricity markets. At this scale, renewable ammonia would, by merit of its ease of storage and transport, enable renewable energy trading across continents.
The IEA's report, Renewable Energy for Industry, will be highlighted later this month at the COP23 in Bonn, Germany, and is available now from the IEA's website.
On August 1, 2017 the Japan Government’s New Energy and Industrial Technology Development Organization (NEDO) announced that it will proceed with funding for the construction of a hydrogen production plant in Namie Township, about ten kilometers from the site of the Fukushima nuclear disaster. The project’s budget is not mentioned, but the installation is projected to be “the largest scale in the world” -- in other words, a real bridge to the future and not a demonstration project.
The project no doubt has a variety of motivations, not least the symbolic value of a renewable hydrogen plant rising in the shadow of the Fukushima Daiichi nuclear station. In economic terms, though, it appears to be a dead end. This is unfortunate because a similarly conceived project based on ammonia could be a true bridge-building step that aligns with leading-edge developments elsewhere in the world.
The NH3 Fuel Association has finalized details of its Sponsors Reception on Wednesday November 1 at the AIChE Annual Meeting in Minneapolis, and has also announced an additional sponsor for the conference: Starfire Energy.

Ammonia energy has gained recognition from the United States Department of Energy, in both bottom-up and top-down programs. This establishes ammonia energy in the world’s largest economy as a legitimate target for both public- and private-sector investment.
Yara, the world's biggest producer of ammonia, has announced that it intends to build a demonstration plant to produce ammonia using solar power, near its existing world-scale plant in the Pilbara, in Western Australia.
It expects to complete the feasibility study this year. Next year, in 2018, Yara hopes to finish the engineering design and begin construction so that it can complete the project and begin production of carbon-free ammonia in 2019.
Today, we saw probably the single most important announcement in the five years that I've been tracking sustainable ammonia production technologies.
Global ag-input giant Bayer and MIT-spin off Ginkgo Bioworks ("we design custom microbes") announced a USD $100 million investment to engineer nitrogen-fixing bacteria into seed coatings, potentially displacing ammonia from its fertilizer market.
On the other side of the world, in the Philippines, researchers are developing another use for another bacteria: industrial-scale algal ammonia synthesis. This would allow ammonia to become a carbon-free biofuel, creating a new and much, much, much bigger market for ammonia: no longer fertilizer but energy.
A paper has just been published by researchers in The Philippines who set out to determine the most environmentally benign way to produce, transport, and use ammonia as a fuel for vehicles.
This new work provides a detailed life cycle analysis of a broad range of ammonia technologies, evaluating both carbon and nitrogen footprints of each, and identifying the optimal "well-to-wheel" pathway. Their results support the idea that using ammonia for energy presents a safe and sustainable way to bring about the hydrogen economy.
