Dortmund/Germany – Decarbonization is a major lever to protect the climate. Even better if existing assets can be preserved while converting them to carbon-free technologies. This is why Grupo Fertiberia engaged Thyssenkrupp Uhde to reduce the carbon footprint of its existing ammonia plant in Puertollano, Spain. The original plant was licensed and built by Thyssenkrupp Uhde in 1969 with a nameplate capacity of 600 metric tons per day (mtpd). It has been in operation ever since, using naphtha as the original feedstock.

Since the 1980s, Fertiberia has been reducing their GHG emissions through several revamps of the unit. Thyssenkrupp Uhde helped their customer to achieve this goal by revamping the plant so it could switch over to natural gas as feedstock and by improving the energy efficiency of the unit. In 2022, with its Net Zero By 2035 strategy, Fertiberia started the production of green hydrogen (20 MW water electrolysis unit) and green ammonia at its Puertollano site, becoming a global pioneer in the energy transition of the fertilizer sector.

Today, Thyssenkrupp Uhde is providing its expertise to further enhance the feedstock switch and partially convert production from grey to green ammonia by injecting green hydrogen.

David Herrero, Industrial Director at Fertiberia: “We are the first company in the agri-food sector that is committed to being carbon neutral within the next decade. This project is another step forward towards our goal to become one of the world leaders in the manufacture of low-carbon ammonia.”

Nadja Håkansson, CEO Thyssenkrupp Uhde: “We are very proud to have been selected once again by our long-standing customer Fertiberia to further decarbonize its production. By gradually replacing fossil-based ammonia production with green ammonia production, we have a huge lever for the green transformation of agriculture and entire industry sectors.”

The revamp concept is to maintain nameplate capacity while minimizing hardware modifications as much as possible. Greenhouse gas emissions will be further reduced by replacing a significant portion of the natural gas with green hydrogen. The necessary green hydrogen will come from a 50 MW water electrolysis unit which runs on renewable energies. With this modification, up to 40 % of the site production will be decarbonized.
