ABB TechTalks: Icebreaker Battery Study

Recorded webinar


ABB has conducted a study to show how an energy storage system could help improve the overall power efficiency of icebreakers, saving fuel and reducing emissions.

In this webinar, ABB Marine & Ports experts will present the key findings from this study. The onboard energy storage simulation results indicate substantial power efficiency and emission reduction benefits for both LNG and diesel operation.

  • Improving performance and cutting emissions of an icebreaker through energy storage
  • Operational profile of the Polaris icebreaker
  • Simulation results and key findings
