Gigawatt-scale electrolyzer manufacturing and deployment
Article

ANNUAL REVIEW 2019: Electrolyzers have featured heavily at this year's Ammonia Energy Conference, which ended today. How much can innovation increase efficiency? How far can volume manufacturing drive down capex? How much could process integration with Haber-Bosch deliver improved ammonia production? How realistically can new, sophisticated strategies optimize variable and baseload power inputs? These technical questions are all important, but none defines profitability. While progress is being made on all these fronts of research and development, major industrial projects are still moving forward.

Ammonia in China: change is coming
Article

ANNUAL REVIEW 2019: In the ammonia industry, Chinese data is notoriously hard to verify. Without question, the country produces more ammonia today than any other nation, and yet it has recently closed million of tons of annual capacity. Its cities are smothered in pollution, and its coal-based ammonia plants use the dirtiest technologies available. Huge questions remain. One answer is clear: China has repeatedly proven its desire and ability to become a global leader in developing and deploying clean technologies in the explicit effort to combat climate change. Within China, therefore, the question of large-scale adoption of ammonia energy technologies is increasingly becoming simpler. When?

The mining industry: a driving force behind green ammonia
Article

ANNUAL REVIEW 2019: Ammonia is too often assumed to be only a fertilizer. This assumption overlooks other important uses for the chemical, large and small, in every corner of our economy. Some of the recent green ammonia announcements suggest that these other industries might, in fact, present better economic fundamentals for green ammonia investments than the fertilizer industry. Alternatively, these companies might have set their sights on becoming first movers in developing the commodities of the future. Time will tell but, if the last 12 months is any guide, the mining industry could be a force for change in the ammonia industry.

The fertilizer industry is learning to love green ammonia
Article

ANNUAL REVIEW 2019: Green ammonia is no longer a lonely venture for Yara, which used to appear alone among fertilizer producers in its desire to reduce carbon dioxide emissions from ammonia plants. While dozens of green ammonia demonstration projects and prototype technologies have been demonstrated in recent years, this progress was mostly achieved by energy companies and technology start-ups - and Yara. In the last year, however, fertilizer producers on five continents have begun feasibility studies, launched pilot demonstrations, or simply gone ahead and re-engineered their ammonia plants to replace fossil fuel inputs with renewable hydrogen.

The maritime sector's ammonia learning curve: moving from scenario analysis to product development
Article

ANNUAL REVIEW 2019: The maritime industry is learning about ammonia fast. It is searching for a new bunker fuel, and ammonia is one of the few options that can realistically deliver a 50% reduction in the sector's GHG emissions by 2050. The IMO declared this target in April 2018 and, in last year's Annual Review, I wrote about all the reports that were published demonstrating that ammonia could deliver this outcome. In the last 12 months, by contrast, we have moved quickly beyond analysis and into engineering design, technology testing, and product development.

IHI Corporation pushes its ammonia combustion technologies closer to commercialization
Article

This week, an article in Japan Chemical Daily disclosed IHI Corporation's future plans for its range of ammonia combustion technologies, each of which has been demonstrated in the last year. These include "ammonia-coal co-fired thermal power boilers, ammonia-fired gas turbines and direct ammonia solid oxide fuel cells (SOFCs)." Under the headline "IHI Speeds up Development of Several Ammonia-Based Technologies," the article describes the company's ambitions for scaling-up each of these technologies, and provides a schedule for its next set of demonstration projects.
