ZEM e-BOX – A Smart Retrofit Battery Solution for Workboats

The ZEM e-BOX is an innovative battery solution designed to transform diesel-powered workboats into efficient electric hybrids. By reducing engine idling, fuel consumption, and CO₂ emissions, the e-BOX provides a cost-effective and sustainable upgrade for maritime operations.

Key Features

  • DNV Type-Approved: Ensuring safety and compliance for marine installations.

  • Plug-and-Play Retrofit: Easily integrates with existing diesel engines to enable hybrid operation.

  • Scalable Energy Storage: Available in 90 kWh and 180 kWh configurations, with the option to install multiple units for additional capacity.

  • Outdoor-Ready Design: Engineered for robust, deck-mounted installation.

  • Reduced Environmental Impact: Cuts CO₂ emissions by up to 100 tons per year per workboat.

  • Lower Fuel Costs: Saves between 20,000 – 40,000 liters of diesel annually.

  • Improved Work Environment: Reduces exhaust, noise, and vibrations for a cleaner and more comfortable workplace.
