Gdynia forms a part of a Polish metropolitan area Tricity, together with Sopot and Gdańsk. Located on the Baltic Sea, it plays an important role in naval economy and international trade as a seaport. Apart from cargo, Gdynia offers also a regular ferry service to Sweden. 
Public transport in Gdynia: Apart from regular buses, Gdynia is one on three cities in Poland to provide trolleybus service. They boast popularity and transport around 350 million people every year.
In the project: The ELIPTIC activities in Gdynia are led by PKT with support of the University of Gdansk.
ELIPTIC use cases in Gdynia:

Pillar A - Opportunity (re)charging of e-buses connecting Tricity agglomeration based on trolleybus infrastructure

The Use Case Team analyses possibilities how to electrify public transport services in Tricity area. As the first step, the operation of trolleybuses on existing line is planned to be extended – once leaving the catenary network in Sopot, the trolleybus operates for 4-5 km with lithium-ion battery traction up to sports stadium Ergo Arena. Then, loaded conventionally under the network, it comes back to Gdynia. Additionally, the local operator, PKT, plans to create a loop for electric vehicles to park and load any electric vehicles. Potential localization of such a loop close to Ergo Arena will be analysed, as well as the possibility to extend off-traction operation of trolleybuses. The use case analyses the electric energy saving potential as well as the cost-benefit ratio of such electric service plans.

Pillar A - Replacing diesel bus lines by extending trolleybus network with trolley-hybrids

The trolleybus network in Tricity is analysed in order to identify potential routes of current diesel buses which could be used to extend the existing trolleybus network. The continuation of these lines is based on trolley-hybrid buses running in autonomous mode on battery traction. The study uses also data from the Gdynia demonstration of the CIVITAS-DYNAMO project, in which trolleybus operation on line 21 is extended to service the new central area in Gdynia by 2 km without catenary connection. In this Use Case, the extension will be serviced by two new trolleybuses equipped with innovative Lithium-Ion batteries and two other classic vehicles witholder Ni-Cd batteries. The study will help to evaluate the possibility experience, PKT (supported by UG) will evaluate possibilities (incl. CBA / emissions reduction) for further extension /replacement of diesel bus lines with battery-trolleybus including in new metropolitan areas for this type ofservice.
