The Power Box 125

The Power Box 125 represents our vision to deliver the most future-proof energy system for the maritime sector. It is powered by PEM technology, the most promising long-term solution for zero-emission shipping, and builds on our proven 8th-generation ZEN 60. Now featuring our advanced 9th-generation fuel cell, it addresses the flaws of traditional systems while integrating HELINOR Energy’s unique advancements to set a new standard. The result?

A scalable fuel cell system

Tailored for the maritime sector, the Power Box 125 delivers a constant stream of power with world-class energy efficiency and high redundancy. Designed with safety in mind, it ensures an unchanged operational pattern and maneuverability for your vessel.

Simple to maintain and install, worry free-carbon documentation and scalability flexibility, the PB 125 sets a new standard for tomorrow.

Fuel Cell Power System

The Power Box is the most compact, lightweight and scalable fuel cell system on the market holding world-class energy efficiency.
