Mission Possible, a recent report published by the Energy Transitions Commission, presents an extremely detailed roadmap for "Reaching net-zero carbon emissions from harder-to-abate sectors by mid-century." The report is designed to support the targets of the Paris Agreement by sending "a clear signal to policymakers, investors and businesses: full decarbonization is possible, making ambitious climate objectives achievable."
Ammonia is one of the crucial solutions that make Mission Possible possible. In its 172-pages, the report details the technologies and the economics behind decarbonizing ammonia, the "likely" adoption of ammonia as the carbon-free fuel of choice for long-distance shipping, and the "key role" ammonia will play in enabling international trade in renewable power.
In the UK, an expansive report was published last month that examines the role of Hydrogen in a low-carbon economy. It considers ammonia's role in depth, both as a potential low-cost hydrogen carrier and as a direct fuel.
As a hydrogen carrier, "converting hydrogen to ammonia as a means of transporting it over long distances would have lower costs than transporting it as hydrogen." And used directly, ammonia is "a hydrogen-rich liquid that could be used as an alternative or complementary fuel."
A new report, Roadmap to Decarbonising European Shipping, identifies a mix of three technologies - batteries, hydrogen, and ammonia - as being "by far the most efficient way to decarbonise the sector." Even so, to satisfy demand from EU's carbon-free shipping sector in 2050, this technology mix will require the installation of huge amounts of additional renewable power generation, equivalent to 25% of the EU's total electricity production.

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.
In June, ThyssenKrupp announced the launch of its technology for "advanced water electrolysis," which produces carbon-free hydrogen from renewable electricity and water. This "technology enables economical industrial-scale hydrogen plants for energy storage and the production of green chemicals."
Two weeks later, in early July, ThyssenKrupp announced that it was moving forward with a demonstration plant in Port Lincoln, South Australia, which had been proposed earlier this year. This will be "one of the first ever commercial plants to produce CO2-free 'green' ammonia from intermittent renewable resources."
The German conglomerate is one of the four major ammonia technology licensors, so its actions in the sustainable ammonia space are globally significant.
Last week, I wrote about a crucial new report that discusses four fuel technologies: batteries, hydrogen, ammonia, and nuclear. These could reduce the shipping sector's emissions in line with targets set in the IMO's Initial GHG Strategy. The report, Reducing CO2 Emissions to Zero, concludes that "all industry stakeholders ... need to get on with the job of developing zero CO2 fuels." This call to action should be consequential: it comes from the International Chamber of Shipping, an influential industry group that represents "more than 80% of the world merchant fleet."
This week, I provide an example of the kind of research required, with an update on a project that aims to demonstrate "the technical feasibility and cost effectiveness of an ammonia tanker fueled by its own cargo."
Although this project is still in its early days, I want to highlight three aspects that I believe will be crucial to its success. First, the work is being done by a consortium, bringing together many industry stakeholders, each with its own expertise and commercial interests. Second, the scope of research extends beyond conventional engine configurations to include not just new fuels but also new technology combinations; in other words, rather than assess new fuels in old engines, it aims to develop optimized propulsion designs for zero-emission fuels. And, third, its consideration of ammonia as a fuel begins with a comprehensive safety analysis.
A number of green ammonia projects have been announced in the Netherlands since the influential Power-to-Ammonia feasibility study was published in early 2017. Perhaps the most important publication since then, however, is the roadmap published by The Northern Netherlands Innovation Board, The Green Hydrogen Economy in the Northern Netherlands. Its scope, including sections written by consultants from ING, Rabobank, and Accenture, goes well beyond the standard techno-economic analysis and presents a cogent plan for coordinated development of "production projects, markets, infrastructure and societal issues."
Green ammonia features heavily throughout the roadmap, which calls for the construction of 300,000 tons per year of renewable ammonia production in Delfzijl by 2024, as well as for large-scale imports of green ammonia, starting in 2021, which would provide low-cost delivery and storage of carbon-free fuel, cracked into hydrogen, for the Magnum power plant.
In early April the Business Network for Offshore Wind held its 2018 International Offshore Wind Partnering Forum in Princeton, New Jersey in the U.S.. Ammonia energy was not on the agenda, at least as a matter of formal programming. But it did come up during a panel session entitled “Offshore Wind Energy Hydrogen Production, Grid Balancing and Decarbonization.” We know this because Steve Szymanski, Director of Business Development for Proton OnSite (a subsidiary of Norway’s Nel ASA), was on the panel and says he was the one to bring it up. The topic attracted “a lot of interest and a lot of good questions,” Szymanski said. Nel is an industry member of the NH3 Fuel Association.
On February 8, the Royal Society released a policy briefing entitled “Options for producing low-carbon hydrogen at scale.” The briefing evaluates the technical and economic aspects of hydrogen production methods and concludes that it is indeed feasible to produce low-carbon hydrogen at scale. Part of that feasibility, the briefing says, could be based on the use of ammonia as an expedient for hydrogen transport and storage.
Last month, an important new consortium in the Netherlands announced its intention to research and demonstrate "the technical feasibility and cost effectiveness of an ammonia tanker fuelled by its own cargo." This two-year project will begin with theoretical and laboratory studies, and it will conclude with a pilot-scale demonstration of zero-emission marine propulsion using ammonia fuel in either an internal combustion engine or a fuel cell.
