Trendsetter for hybrid buses in Europe
First European city bus with volume-production hybrid technology (2006)
Offer of different diesel-electric hybrid technologies gives operators the choice of suitable hybrid drive systems
Fuel consumption reduced by up to 29%, emissions by up to 78%
Electric mobility

Market leader in trolleybuses
Solaris Trollino trolleybuses have provided electric mobility since 2001
Available in four lengths (12, 15, 18 & 18,75 metres)
Choice of four traction equipment suppliers (Škoda, Medcom, Cegelec, Vossloh Kiepe)
EU & EFTA market leader with 40% market share
Electric mobility
17
Hybrid trolleybus with batteries and supercaps
Demonstrator in Eberswalde as part of EU-funded TROLLEY project
Battery (72 kWh) for 4 km independent operation per 18 km round trip
Fits into existing space on the bus
Other battery sizes are possible
Energy cost per km for hybrid trolleybus is 32% lower than for reference vehicles (fitted with diesel auxiliary units and supercaps)
New possibilities for electric bus systems
Route extension without infrastructure cost
New networks with infrastructure only on highly-used main sections

International projects
ZeEUS
• ZeEUS project focus on the today's challenge in the electrification of bus system, the extension of the fully-electric solution to a wider part of the urban network.
• This goes through the development of electric vehicles of large capacity, and the creation of an infrastructure capable of providing the required charging energy, operated according to non-disruptive and grid-balancing principles.
• The ZeEUS project will cover innovative electric bus solutions with different types of electrical power-train systems.

International projects
Emerald
Project purpose: EMERALD focuses on energy use optimisation and on the seamless integration of the FEV into the transport and energy infrastructure, by delivering clear advances over the state-of-the-art. EMERALD will introduce Integrated in-vehicle energy management, comprising: Dynamic energy-driven management of FEV auxiliaries, Energy-efficient long-range route planning and optimisation, Performance-centric machine learning for consumption prediction, User-centric charge and discharge management, Solaris contribution to the Project concerns primarily participation in testing EMERALD functional system
