Ammonia in China: change is coming

Trevor Brown November 07, 2019

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?

Safety of Ammonia Energy: First Up, the Maritime Use Case?

Stephen H. Crolius November 07, 2019

ANNUAL REVIEW 2019: Ammonia. A hazardous chemical, no doubt. But is it too hazardous to use as an energy vector? This is a legitimate question that must be addressed as other aspects of the ammonia energy concept advance. It is also a question whose unique context can be evoked with two other questions: Haven’t the safety issues already been identified and resolved over the last 100 years of widespread agricultural and industrial use? And even if they have, how will the general public react when proposals for expanded ammonia infrastructure suddenly appear? The earliest tip of this particular iceberg came into view this year when the Dutch naval architecture firm C-Job released Safe and Effective Application of Ammonia as a Marine Fuel.

Technology Advances for Blue Hydrogen and Blue Ammonia

Stephen H. Crolius November 01, 2019

ANNUAL REVIEW 2019: Blue hydrogen – defined as the version of the element whose production involves carbon capture and sequestration (CCS) – represents an alluring prospect for the energy transition. The primary “blue” feedstocks, natural gas and coal, currently set the low-cost benchmarks for storable energy commodities. With the addition of CCS, they are expected to set the low-cost benchmarks for low-carbon storable energy commodities. Blue ammonia is very much included in this frame of reference since CCS could be applied to the CO2 waste stream from the Haber-Bosch process. But neither blue hydrogen nor blue ammonia are sure things; a variety of technical, financial, regulatory, and social issues could stand in the way of their widespread adoption. But work on new technologies that have the potential to ease the way for blue products has come increasingly into view over the last twelve months.

The mining industry: a driving force behind green ammonia

Trevor Brown November 01, 2019

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

Trevor Brown October 25, 2019

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.

Ammonia Energy Mainstreaming Expands to Governments

Stephen H. Crolius October 25, 2019

ANNUAL REVIEW 2019: An item in the last Annual Review described an upwelling of attention for ammonia energy from mainstream media outlets. Over the last 12 months, the process of 'mainstreaming' has started to spread to another important constituency: governments.

Ammonia in the Mix as an Industrial Energy Source

Stephen H. Crolius October 25, 2019

ANNUAL REVIEW 2019: The generation of heat for industrial processes accounts for approximately 10% of global greenhouse gas emissions – which means that finding ways to eliminate this climate footprint is among the pressing technology tasks on our societal to-do list. Developments over the last 12 months suggest that ammonia could play an important role in meeting this challenge.

The fertilizer industry is learning to love green ammonia

Trevor Brown October 25, 2019

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.

Government Investments in Hydrogen: How Does Your Country Compare?

Stephen H. Crolius October 11, 2019

On September 3, the British renewable-energy news portal reNEWS.BIZ ran a story with an intriguing headline: “Scotland launches £3bn green project portfolio.” At first glance, that number (which equates to USD $3.7 billion) looks out of scale with Scotland’s relatively tiny population of 5.5 million. Close reading reveals that the £3 billion is not the amount that will be invested by the Scottish government, but rather the value of the “investment portfolio” of green businesses the program is intended to galvanize over the next three years. But still one wonders, how does £3 billion stack up against other national programs aimed at supporting the sustainability transition?

IHI Corporation pushes its ammonia combustion technologies closer to commercialization

Trevor Brown October 11, 2019

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.
