Bio fueled hybrid vehicle for airport ground handling operations

To develop a hybrid power pack for ground utility vehicles at the copenhagen airport, which both improves fuel efficiency and reduces the emission of ultra fine particles. The power pack consists of a fuel cell, a combustion engine and a battery and it operates on bio fuel.

The purpose of the HYBRID VEHICLE project is to demonstrate a utility vehicle powered by State-of-the-Art energy technology, which will both improve the energy efficiency and reduce the particle emissions at the Copenhagen Airport. Especially the emission of ultra fine particles represents a significant problem for the working environment at airports (and larger cities in general). This demonstration is performed by developing a hybrid power pack for electrical propulsion and ground handling operations. Many of these utility vehicles have a very 'dis-continuous' usage, which includes long periods of idling at low power consumption and shorter periods with significantly higher power consumption. The new energy system will be based on a hybrid system combining fuel cells, a combustion engine and a battery. The fuel cells and engine will run on renewable bio-DME (Di Methyl Ether). The advantage of this concept is that the size of the individual components can be reduced (as compared to a non-hybrid system), while improving the overall energy efficiency by using the most efficient hybridization for a given power requirement. Furthermore, the use of DME eliminates the formation of particles in the exhaust significantly. The project will develop and demonstrate the concept using an airport utility vehicle. This will enable system design, optimisation and demonstration of components and concepts. Energy efficiency, particle emissions and formation of nitrogen oxides will also be investigated. Identification of Danish partners for commercial exploitation of the project results will be an important aspect. The fuel cell technology is based on High Temperature PEM (HTPEM) fuel cells. A HTPEM stack in combination with a bio-combustion engine will function as range extender and power booster for the battery powered electric utility vehicle. The energy requirements of the application deem a pure battery solution impractical. However, the proposed combination fulfills the needs for both power and energy. The HTPEM fuel cell will operate on reformed DME. The scope of the project is to demonstrate the feasibility and advantages the hybrid system for electrical propulsion and ground handling operations. Extensive testing of the technology at DTU and Copenhagen Airport is performed in order to validate the principles. Furthermore, bio-DME (together with bio-methanol and bio-gas) has by far the largest potential for CO2 reduction related to transportation, meaning that the development of DME ICE technology could result in a general reduction of CO2 related to transportation. The project addresses a number of highly important aspects for implementation of sustainable fuels for electrical propulsion. Fuel cell technology (DTU ECS and DPS), Stack technology (Teksis and DPS), Bio fueled internal combustion engine 'DTU MEk and Danfoss), Battery and power management (Li-Balance) and End)-user (Copenhagen Airport and Vestergaard).
