Green shipping
AG Reederei Norden-Frisia has set out to make island mobility climate-friendly and independent: since March 2025, the all-electric catamaran FRISIA E-1 has been connecting the mainland with the island of Norderney emission-free and is charged with electricity directly from two STABL battery storage units. These are another building block in the comprehensive concept for generating, storing and using electrical energy.
Lower Saxony’s largest charging park was put into operation in the parking areas at the headquarters of AG Reederei Norden-Frisia in Norddeich as early as 2024. With a capacity of 1.6 MW and 242 charging points, guests and employees can conveniently charge their e-vehicles there. The system will be expanded in the future, and an additional 750 kW ground-mounted photovoltaic system is already being planned.
The combination of solar power from the covered car parking spaces and the new STABL battery storage units enables particularly efficient energy management:
Maximum use of self-generated solar power
Stable grid feed-in when charging many vehicles at the same time
Higher degree of self-sufficiency for the entire operation
The two storage units not only ensure maximum self-utilization of solar power, but also significant grid stability during charging. This creates an energy system that goes far beyond simply supplying ships and can serve as a beacon project for other ports and island regions.
Battery storage systems with a total capacity of 1,849 kWh and an output of 608 kW are at work in STABL’s two 20-foot containers. One particularly sustainable feature is that they are equipped with second-life battery modules from electric vehicles, which are reused in a resource-efficient manner thanks to STABL’s innovative multilevel inverter technology.
This is why the shipping company’s aim is to create a closed energy cycle: from solar power generation to intelligent storage and efficient use on land and at sea.
This success story impressively demonstrates how emission-free e-mobility, local energy generation and battery storage can work together intelligently. With the courage to innovate and technological vision, the shipping company proves that real change is possible.
We at STABL Energy are proud to be part of this role model project with our storage solutions. Because it represents a further step towards the maritime energy transition and sends a strong signal from the heart of East Frisia. Ship ahoy!
