Cooling can be placed in separate rooms, providing more efficient cooling of the batteries. A heating element is connected in the cooling circuit to ensure that the batteries do not fall below the optimal operating temperature when not in use.

  • Lower emissions (NOx and SOx)
  • Lower fuel consumption (up to 60%)
  • Shorter generator/diesel engine running time (1–7 hours)
  • Less generator/diesel engine maintenance
  • Less acoustic noise
  • Reduced vibration
  • One of the most dependable batteries on the market
  • Batteries approved by DNV-GL
  • Low CO2 footprint
  • Cobalt-free
  • Long working life
  • Flexible and redundant (multiple strings)
How does the system work?

By combining batteries with a diesel engine, the diesel engine can be run at the optimum load point, while charging the batteries and operating the barge. When the batteries are fully charged, the system automatically switches to battery operation and stops the diesel engine.

The system consists of:

  • Batteries
  • Battery rack
  • Inverter / control cabinet
  • Transformer
  • Energy Management System
  • Water cooling

With our hybrid dashboard you can easily keep track of how much fuel your generators are using at all times and how much the hybrid system is saving you.


Based on technical and financial studies, we can help you choose the best configuration for a new installation or a retrofit. With ZEM, we have also developed a fixed battery case that is much more space-saving than previous solutions.
