Transforming from grey ammonia and fertiliser production towards green fertiliser production is not done overnight. It is a puzzle with many pieces. For each site we have to make a different puzzle and design the pieces accordingly. The required technologies also need to develop further. Water electrolysis has not yet been implemented on a large scale and on our site in Puertollano a 20 MW electrolyser will be commissioned this summer. The hydrogen for this electrolyser will be used for green ammonia and green fertiliser production in a hybrid setup.
The learnings from this new combination will be applied for new projects in our pipeline. The combination of grey and green ammonia production in one plant is not the most preferred solution, but a daring and necessary first step. New projects are being designed to replace the importation of grey ammonia with our own green ammonia production in Sagunto and Aviles in Spain.
The technical, logistical and economic considerations behind these choices are discussed in this presentation.
