Sea Li-ion – preparing ports for the future

Taking the maritime sector’s electrification one step further by designing energy storage systems for ports.

The next step for the electrification of shipping

The Sea Lion project consists of a study looking into creating two large Energy Storage Systems (ESSs) for storing electricity, which would allow for charging ships fitted with batteries. These ESSs are to be placed in the ports of Gothenburg and Kiel. These two ports have the potential to cater to a growing interest in E-vessels in the Baltic and the North Sea. Their capacity for fast-charging directly alleviates concerns by shipowners on the future availability of shore-side electrical power.  

The project’s key goal is to take the maritime sector’s electrification one step further by designing the ESSs for ports. However, it would be shortsighted to do that in isolation. Ensuring Lithium-ion (Li-ion) batteries’ recycling potential and assessing the impact of an ESS installation on the electricity grid will be vital to ensure a sustainable leap forward. The battery value chain is a strategic value chain for the future of Europe, in particular with respect to clean and low emission mobility. The Action has a broad scope, covering the entire battery value chain. It is highly ambitious and innovative. It aims to develop technologies and processes that are not currently available and will allow significant performance improvements and reduce environmental impact. 

 The project will consist of three main activities:  

  • Creating the design of Energy Storage Systems for use in ports. 
  • Evaluating the recycling potential of lithium-ion batteries and.
  • Assessing the impact of the ESSs on electricity grid systems.
