Technology Advances for Blue Hydrogen and Blue Ammonia
Article

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
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.

Ammonia in the Mix as an Industrial Energy Source
Article

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
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.

Green Ammonia Plants in Chile, Australia, New Zealand
Article

Green ammonia plants are being announced quicker than I can report. Here is a summary of four new projects that propose to use electrolyzers, fed by renewable power, to produce hydrogen for ammonia production. These are big companies, operating in regions with excellent renewable resources, making significant investments in their future. In Chile, it is Enaex, a major ammonium nitrate manufacturer, supplying explosives to the mining industry. In Australia, it is Incitec Pivot, "the second largest supplier of explosives products and services in the world," and Wesfarmers, "the largest Australian company by revenue," according to Wikipedia. In New Zealand, it is Ballance-Agri Nutrients, a big farmers' co-operative and the country's sole fertilizer producer. Each aims to make its business "future-proof." The transition from fossil ammonia to renewable ammonia is underway.
