The ammonia industry is transitioning towards sustainability at remarkable speed. In the last week alone, three major project announcements signal the availability of millions of tons of low-carbon ammonia this decade, and enthusiasm for rapid and complete transformation of the industry. Decarbonizing ammonia is no longer viewed as a challenge — now, this is quite clearly an opportunity.
This week, Japan’s new Prime Minister Yoshihide Suga announced that by 2050 the country would drive its greenhouse gas emissions to zero and achieve carbon-neutrality. Earlier in the month, the Japanese electric utility JERA announced its intention of “achieving zero CO2 emissions by 2050.” Its first step toward this goal was its 'JERA Zero CO2 Emissions 2050 Roadmap for its Business in Japan.'
Earlier this month the journal Science published “Recent advances in solid oxide cell technology for electrolysis." The paper advances two important theses: first, solid oxide electrolysis cell (SOEC) technology has an important role to play in the sustainable energy economy of the future; second, SOEC technology has achieved a set of economics that make commercial viability possible today.
Last week, two new low-carbon ammonia production projects were announced, both of them large-scale and largely CO2-free. Monolith Materials announced a 275,000 ton per year “clean ammonia” plant in Nebraska, in the heart of the US cornbelt. The plant will begin construction in 2021, expanding the existing demonstration plant, using Monolith’s methane pyrolysis process powered by 100% renewable electricity. Ørsted and Yara announced their plan to produce 75,000 tons per year of “green ammonia” at Yara’s existing Sluiskil plant in the Netherlands. They intend to install a 100 MW electrolyzer, using Ørsted’s offshore wind energy, with a final investment decision expected in 2021-2022, and production beginning in 2024-2025.
From 2014 to 2018 Bunro Shiozawa served as Deputy Program Director of the SIP “Energy Carriers” initiative in Japan. Over the last year he has published a ten-part series of articles that describe and reflect on the research supported by the initiative. Part 4 covers ammonia combustion technologies. The first half of the article was posted on September 23, 2020, in Shiozawa's English translation. The second half follows.
Last week, Saudi Aramco and the IEEJ attracted significant media attention when they announced that the first “blue” ammonia has been shipped to Japan. Aramco’s celebration of this shipment of 40 tons of ammonia (not 40 thousand or 40 million, just 40 tons) raises many questions, but makes three things clear. First, projects to demonstrate the carbon footprint of specific batches of low-carbon ammonia are now underway, and these case studies will inform the design of an international low-carbon ammonia certification scheme. Second, there is an urgent need to establish definitions across the industry, or risk losing credibility. Third, Aramco (absolutely the most profitable company in the world, with over a hundred oil and gas fields and almost 300 trillion scf of natural gas reserves) has sent a clear signal that it intends to make and sell ammonia as a decarbonized energy commodity.
The Senate Energy and Natural Resources Committee, led by Chairman Lisa Murkowski (R-Alaska) and Ranking Member Joe Manchin (D-West Virginia), recently hosted a hearing on offshore energy technologies. I was invited to testify on technology and policy options for eliminating greenhouse gas emissions from the marine shipping sector, and I used the opportunity to spotlight ammonia's central role in that effort.
This week, DNV GL published its annual Maritime Forecast to 2050, concluding that “e-ammonia, blue ammonia and bio-methanol are the most promising carbon-neutral fuels in the long run.” DNV GL’s assumptions that determine this long run, however, suggest a significant mid-term reliance on fossil LNG. This risks locking the industry into a long-term emissions trajectory incompatible with the IMO’s 2050 GHG targets, in part because of significant fuel supply and infrastructure investments. These investments could become more ‘sticky’ than expected. A host of alternative opinions have been published in the days before and after DNV GL published its report. These suggest that, for ammonia, the long run could begin this decade. Among others, MAN ES has announced that its ammonia engine will be available for retrofits by 2025.

In recent weeks, the Japanese shipping company NYK Line has announced a series of high-profile research and development collaborations that aim to establish ammonia fueled vessels and fuel supply. Its partners in these projects include classification society Class NK, engine manufacturer IHI Power Systems, and shipbuilder Japan Marine United Corporation. Three vessel types have been announced, so far, including an ammonia-fueled ammonia gas carrier, an ammonia barge for offshore bunkering, and an ammonia-fueled tugboat (for navigating the barge). Pushing beyond the initial research phase, these collaborations aim for commercialization and to put these vessels “into practical use.”
