- thyssenkrupp nucera will supply 300 MW (15 x 20 MW) alkaline water electrolyzers to Moeve for the Onuba project in Huelva, Spain.
- Onuba's 300 MW capacity targets ~45,000 t/yr of green hydrogen production and ~250,000 t/yr CO2 savings.
- Moeve took final investment decision in early March 2026; Onuba is the first phase of the Andalusian Green Hydrogen Valley linking southern Spain's renewable supply and ports to European industry.
