The Urban Electrification Benchmark
By Staff Report · 2 min read

In a record-breaking move for the German maritime sector, Lehmann Marine has secured its largest order to date: supplying 3.8 MWh energy storage systems for three new, fully electric ferries in the Port of Hamburg. Built by SET Tangermünde for HADAG, these "Type 2030e" vessels represent a shift from hybrid experiments to utility-scale, zero-emission urban transit. By replacing diesel dependent engines with high-capacity battery cubes, Hamburg is establishing a scalable model for port-city air quality.
Decoding the 3.8 MWh CUBE Architecture
The heart of this project is the CUBE energy storage system, a modular solution designed specifically for the aggressive duty cycles of port service.

- High-Capacity Zero-Emission Berthing: Each 30-meter ferry will carry 3.8 MWh of battery capacity, a massive amount of energy for a passenger vessel of this size. This enables the ferries to operate 100% electrically and silently, removing the NOx and particulate matter emissions that traditionally plague urban waterfronts.
- Modular Serviceability: The CUBE system’s architecture allows for "plug-and-play" maintenance. In a high-frequency ferry environment where downtime is not an option, the ability to service or replace modules without dry-docking the vessel is a significant operational advantage.
- A "Lighthouse" for Onshore Charging: While the focus is on the onboard batteries, this project creates a massive demand for high-speed Onshore Power Supply (OPS). These ferries will require rapid, automated charging interfaces at the pier to maintain their 3.8 MWh charge state during short stopovers, reinforcing the business case for terminal-wide electrification.
