In the remaining months from April to October we concluded the research and derived overall following findings: The results show how Shared Autonomous Electric Vehicles (SAEVs) could be effective at absorbing excess generation from renewable energy, as well as providing more complex grid services which are today provided by large fossil-fueled power plants. The use of smart charging could significantly reduce charging cost, and could also enable important synergies between the transport and energy system: the results show how the introduction of grid services could induce a situation where, all other things equal, expanding the fleet saves the fleet operator money. This has consequences also for the transport service quality, since a larger fleet is able to provide a better service with lower waiting times. Moreover, the research shows how SAEVs could be an attractive alternative to existing transport modes. We show how these shared transport systems could attract a significant proportion of passengers currently using private cars, public transport or active modes such as walking.
With respect to our work on electric buses we showed how these can be used to support and stablise energy demand and how "energy grid services" can be an additional source of income for public transport providers. We discussed different forms of contracts a bus operator might make with an energy provider.
