Last month, a heavyweight consortium of local and global companies announced plans to collaborate on a project to design, build, operate, and evaluate a demonstration plant to produce "green ammonia" from water, air, and renewable energy in The Netherlands.
This is one practical outcome of last year's Power-to-Ammonia study, which examined the economic and technical feasibility of using tidal power off the island of Goeree-Overflakkee in Zuid-Holland to power a 25 MWe electrolyzer unit, and feed renewable hydrogen to a 20,000 ton per year green ammonia plant.
This new demonstration plant phase of the project will still be led by the original developer, Dutch mini-ammonia plant developer Proton Ventures. However, its partners in the venture now include Yara and Siemens, as well as speciality fertilizer producer Van Iperen, and local sustainable agricultural producer, the Van Peperstraten Groep.
Goeree-Overflakkee, in the southwest corner of The Netherlands, already produces more renewable power than it can consume. But, by 2020, this small island will generate a full 300 MWe of solar and wind, which far "exceeds the electricity demand on the island, rated at maximum 30 MWe peak."
Stedin, the local grid operator, has the expensive task of integrating these and future renewable resources into its electricity distribution system.
The recent Power-to-Ammonia study included a detailed analysis of Stedin's business case for producing renewable ammonia as a way to store and transport this electricity - enabling the island to become a net exporter of clean energy.
The Institute for Sustainable Process Technology has just published a feasibility study that represents a major step toward commercializing renewable ammonia.
It examines the "value chains and business cases to produce CO2-free ammonia," analysing the potential for commercial deployment at three companies with existing sites in The Netherlands: Nuon at Eemshaven, Stedin at Goeree-Overflakkee, and OCI Nitrogen at Geleen. The project is called Power to Ammonia.
The team behind it is an industrial powerhouse with serious intentions, and this feasibility study is the first part of their plan: next come the pilot plants and demonstrations. As OCI Nitrogen explains, "there are still many hurdles to be overcome. By setting up pilots for this new technology, we can identify these and find ways to solve them."
