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.
Last week, the UK Department for Business, Energy and Industrial Strategy (BEIS) announced a "£390 million government investment to reduce emissions from industry," with a focus on low-carbon hydrogen supply and clean steel production. As part of this investment, a consortium led by Ecuity Consulting that includes Siemens, Engie, and the Science & Technology Facilities Council (STFC), has been awarded £249,000 to perform "valuable research on the role of ammonia in the delivery of low cost bulk hydrogen for use in the UK energy system."
This week, Yara announced major progress toward producing "green ammonia" at its plant in Pilbara, Australia. Its new partner in this project is ENGIE, the global energy and services group, which last year made a major commitment to developing large-scale renewable hydrogen projects.
I first reported Yara's plans for a solar ammonia demonstration at its Pilbara plant in September 2017. This week's announcement means that the Pilbara project has moved to the next feasibility phase. However, major elements of the project have already been designed and built: during last year's scheduled turnaround for plant maintenance, the hydrogen piping tie-in was completed - meaning that the Haber-Bosch unit is ready to receive hydrogen directly, as soon as an electrolyzer has been built to supply it with renewable feedstock.
The second annual European Conference on Sustainable Ammonia Solutions has announced its full program, spread over two days, May 17 and 18, 2018, at Rotterdam Zoo in the Netherlands. The international cadre of speakers, representing a dozen countries from across Europe as well as the US, Canada, Israel, and Japan, will describe global developments in ammonia energy from the perspectives of industry, academia, and government agencies.
This week, at the World Economic Forum in Davos, the leaders of 13 global companies, representing more than EUR 1 trillion in annual revenues, announced the launch of the Hydrogen Council.
This new global initiative is important for obvious reasons: it presents a compelling "united vision and long-term ambition" for hydrogen, it promises global engagement with "key stakeholders such as policy makers, business and hydrogen players, international agencies and civil society," and it pledges financial commitments to RD&D totaling EUR 10 billion over the next five years.
It is important for a subtler reason too: it is the first hydrogen industry promotion I've seen that includes ammonia. It includes ammonia both implicitly, encompassing "hydrogen and its compounds," and explicitly, listing ammonia as a "renewable fuel" in its own right.
