Rolls‑Royce and Duisburger Hafen AG opened a self‑sufficient, CO₂‑neutral energy system for the new Duisburg Gateway Terminal on July 8, 2025, according to Rolls‑Royce's release.
Rolls‑Royce supplied two mtu H₂ combined heat and power plants, an mtu EnergyPack battery storage system and two mtu fuel cell systems.
The system includes a 1.3 MWp photovoltaic system integrated via intelligent energy management software and is supplemented by mtu battery storage and fuel cells when solar power is insufficient.
At full operation, the terminal will require 3,500 MWh/a of electricity and 77 MWh/a of heat.
The PV system is expected to generate 1,123 MWh annually and covers about 10,000 m².
The battery EnergyPack offers 1.5 MW output and 1.6 MWh capacity. The two H₂ CHP units deliver 2 × 931 kW electric output and 2 × 748 kW thermal. The fuel cell systems are two PEM units producing 2 × 600 kW.
The project, branded Enerport II and funded by Germany’s Federal Ministry for Economic Affairs and Energy, aims to benchmark sustainable energy supply in logistics centres.
Partners include the Fraunhofer Institute UMSICHT, Westenergie Netzservice, Netze Duisburg, Stadtwerke Duisburg AG and Stadtwerke Duisburg Energiehandel.
