Casale SA (Lugano, Switzerland) is studying the application of its Casale Ammonia Converter technology for application for Yara International ASA (Oslo, Norway) at its fertilizer factory at Herøya (Norway).
The existing plant will be converted, replacing the current hydrogen production via liquefied fossil gas, with green hydrogen based on renewable energy. By so doing, Yara will be able to create emission-free ammonia.
As part of this initiative, Casale is undergoing a study of its technology, including the design of a brand-new ammonia converter internals that could intrinsically provide GHG emission reduction.
Furthermore, Casale is designing its reactor in order to let the Herøya plant synthesis loop be able to initially work with the traditional source. After the decarbonization of the plant, the Casale design of the reactor will allow ammonia synthesis to switch to the new source of green hydrogen without any additional intervention.
In this first decarbonization step, the plant will produce enough hydrogen equivalent to 20,500 tons of green ammonia per year, which converts into between 60,000 and 80,000 tons of fossil-free mineral fertilizer.
