Spain – Puertollano in southern Spain is currently home to Europe’s largest electrolyzer for hydrogen production, run by Iberdrola, with a capacity of 20 megawatts. It runs entirely on solar energy. With this green hydrogen, producer Fertiberia first makes ammonia and then fertilizer. A very elegant and hopeful development. Watch the vlog of Hydrogen Trail Europe, while visiting the Spanish frontrunners.
However, it will be some time before a significant proportion of the world’s fertilizer is produced in this way. In Puertollano it is now only ten percent of the total production. The rest of the fertilizer is still made from hydrogen from natural gas and nitrogen from the air. Fertiberia has plans to scale up the green route at multiple locations, but that will take time.
