Haldor Topsoe has greatly improved the near-term prospects for green ammonia by announcing a demonstration of its next-generation ammonia synthesis plant. This technology uses a solid oxide electrolysis cell to make synthesis gas (hydrogen and nitrogen), which feeds Haldor Topsoe's existing technology: the Haber-Bosch plant. The product is ammonia, made from air, water, and renewable electricity.
The "SOC4NH3" project was recently awarded funds from the Danish Energy Agency, allowing Haldor Topsoe to demonstrate the system with its academic partners, and to deliver a feasibility study for a small industrial-scale green ammonia pilot plant, which it hopes to build by 2025. There are two dimensions to this technology that make it so important: its credibility and its efficiency.
SUMMARY STATUS: Planning Phase
Midwest BioEnergy is planning a series of small waste-to-ammonia plants at municipal and industrial sites in the heart of the ammonia fertilizer market. The Monmouth plant will be the "proof of concept." Some equity in place; debt financing secured, contingent upon equity investment.
UPDATED: 03/07/2016 — see Change Log. No further updates expected.
PROJECT: Brownfield urea plant
SUMMARY STATUS: Cancelled
Agrebon is no longer developing the Casselton plant. There have been no announcements regarding this site since April 2013. The team behind Agrebon regrouped as Bayotech, which continues to develop small-scale, modular ammonia reactors but shifts the team's focus away from biomass feedstocks.
OWNER: University of Minnesota
PROJECT: Pilot plant
SUMMARY STATUS: Operational
The Wind-To-Ammonia project at the University of Minnesota is a fully operational pilot plant, demonstrating the feasibility of using renewable energy to produce carbon-free ammonia.
