PortLiner's value chain approach

PortLiner's approach for the development of the flow battery concept in inland navigation is carried out along the lines of the value chain, including:

  • Ship design and architecture
  • Ship building (hull and subsequent outfitting and finishing), with input and supply from a range of maritime suppliers
  • Battery configuration and equipment supply including Battery Management System and electrolyte
  • Electric system engineering, system integration and installation
  • Battery recharging infrastructure and electricity supply
  • Classification society, to certify vessels, battery systems and waterborne recharging infrastructure
  • Financing, for vessels, battery equipment & electrolyte, recharging infrastructure
  • Chartering, including terminals, brokers and shippers

PortLiner organizes and brings together every link that together represent the value chain,  a cluster of more than 40 companies that together create and build the PortLiner flow battery propelled vessels.

 

Please find below a brief presentation of four key PortLiner partners.


The Fraunhofer Institute for Chemical Technology, near Karlsruhe in Germany (580 employees) carries out research and development in core competences including chemical processes and energy systems.

The Fraunhofer ICT supports its clients and project partners from the original idea to the prototype phase or even to small-series production, according to their requirements. Clients and project partners are mostly from the automotive and transport sectors. The research group working on batteries has over 35 years of experience with electrochemical energy storage devices for civil and defense applications.  

Regarding redox flow batteries, the Institute offers expertise in the areas of material development and characterization, redox chemistry, stack development and battery systems and simulation. The Institute operates a Redox-flow Application Center, with the necessary infrastructure to test and characterize RFB modules in a power range of up to several hundred kWs.  Separate tank systems enable testing of novel electrolytes on large scale.


Werkina is one of most experienced and successful maritime installation companies in the region. Werkina can handle the design, engineering and construction of complete electrical systems for a wide range of maritime applications. Werkina provides complete electrical systems.

In addition to engine control, Werkina also offers nautical equipment, AC/HVAC, tank measurement and alarming systems and entertainment systems. 


Van Oossanen are independent naval architects and hydrodynamicists with vast amounts of experience in the design of sail and motor yachts, commercial ships and advanced marine vehicles.

Their particular area of expertise is in the field of ship hydrodynamics and performance.


ZEL is a logistics provider exclusively selecting zero emission vessels and vehicles. Their field of expertise is inland container logistics. The PortLiner Anna vessel will be part of ZEL's zero emission portfolio.
