The transport sector in Greece has the largest share in the final energy consumption and the resulting emissions are one of the main sources of atmospheric pollution. This situation is worse in the region of Attica, where nearly half of the country’s private cars circulate in an area equal to 3 % of the total country area; the region’s climatic and geomorphological characteristics further aggravate the environmental problem. This paper examines energy saving and environmental impacts reduction from the penetration of eco-friendly technology passenger cars in this region. Three vehicle technologies are considered: (i) conventional hybrid electric vehicles, (ii) battery electric vehicles and (iii) fuel cell electric vehicles. The influence of the driving cycle is examined through the comparison of two different cycles, the New European Driving Cycle (a regulatory driving cycle) and the Athens Driving Cycle, based on actual driving data. Two alternative scenarios are formulated. The first involves the substitution of all the passenger cars that were registered during the last year (2010) with hybrid and battery electric vehicles that already exist in the Greek market. The second scenario examines the penetration of fuel cell electric vehicles. Both scenarios are evaluated on the basis of their expected energy savings and greenhouse gas emissions reduction. A 7.5 % to 9 % reduction of the CO2 emissions is expected, for the Athens Driving Cycle, if these measures are applied in a five year period.

Driving Cycles

Electric vehicles (EVs) include battery electric vehicles (BEVs), fuel-cell vehicles (FCVs) and fuel-cell hybrid electric vehicles (FCHEVs). The performance of vehicles is usually evaluated using standardized driving cycle tests; however, the results from standardized driving cycle tests deviate from the real-world driving cycle. In order to test the adaptability of EVs to real-world driving cycles, conditions of three typical routes in Tianjin are collected and their characteristics analyzed; then BEV and FCV models are created based on a type of FCHEV to simulate 0–100 km/h acceleration and cruising performance under a real-world driving cycle; finally, a motor bench is used to test the performance of FCHEV under the NEDC (New European Driving Cycle). After the adaptability of the three models to real-world driving cycle is compared based on the simulation and test results, it is found that FCHEV can recycle braking energy and has quick dynamic response, which can be well adapted to the real-world driving cycle.

Hydrogen Mobility Europe (H2ME, 2015–2022) is the largest European Fuel Cells and Hydrogen Joint Undertaking (EU FCH JU)-funded hydrogen light vehicle and infrastructure demonstration. Up until April 2017, the 40 Daimler passenger car fuel cell electric vehicles (FCEVs) and 62 Symbio Fuel Cell-Range Extended Electric Vans (FC-REEV)-vans deployed by the project drove 625,300 km and consumed a total of 7900 kg of hydrogen with no safety incidents. During its first year of operation (to April 2017), the NEL Hydrogen Fueling HRS (hydrogen refuelling station) in Kolding, Denmark dispensed 900 kg of hydrogen, and demonstrated excellent reliability (98.2% availability) with no safety incidents. The average hydrogen refuelling time for passenger cars is comparable to that for conventional vehicles (2–3 min).

The range-extended electric vehicle is proposed to improve the range anxiety drivers have of electric vehicles. Conventionally, a gasoline/diesel generator increases the range of an electric vehicle. Due to the zero-CO2emission stipulations, utilizing fuel cells as generators raises concerns in society. This paper presents a novel charging strategy for fuel cell/battery electric vehicles. In comparison to the conventional switch control, a fuzzy control approach is employed to enhance the battery’s state of charge (SOC). This approach improves the quick loss problem of the system’s SOC and thus can achieve an extended driving range. Smooth steering experience and range extension are the main indexes for development of fuzzy rules, which are mainly based on the energy management in the urban driving model. Evaluation of the entire control system is performed by simulation, which demonstrates its effectiveness and feasibility.

Abstract Potentially large amount of hydrogen resource in China could theoretically supply 100 × 106 fuel cell passenger cars yearly. The Chinese government highly values the hydrogen and fuel cell technology. Policies and plans have been put forward densely in the recent five years. Numerous companies, research institutes, and universities are developing proton exchange membrane fuel cell (PEMFC) and solid oxide fuel cell (SOFC)-related technologies. A preliminary local supplier chain of fuel cell-related technology has been formed. However, the lifetime is still a key issue for the fuel cell technology. More than 3500 fuel cell range extender electric vehicles were manufactured during 2016 and 2018, and at the beginning of 2019, there have been more than 40 hydrogen refueling stations including both under operation and under construction. It is estimated the number of fuel cell-based electric vehicles will reach 36,000 by the end of 2020; therefore, lack of hydrogen refueling station has become a key restriction for development of the fuel cell vehicle industry.

And Diffusion

Battery Electric Vehicles are regarded as highly important to reach environmental goals, such as CO2 savings in the transport sector. Despite governments making strong efforts to encourage their adoption and diffusion, sales still remain at a notoriously low level. One of the reasons may be the lack of a deeper understanding of the differences among potential adopters of Battery Electric Vehicles. To close this research gap, the authors segment adopter groups in a new way. They simultaneously use preferences for product attributes and personal characteristics to identify and characterize adopter groups of Battery Electric Vehicles. In this way, adopters can be effectively segmented, uncovering a more precise picture of adopters’ needs. Moreover, the authors introduce a three-step-procedure combining inputs from an adaptive choice-based conjoint experiment with a questionnaire. This approach can be used to segment adopter groups of other eco-innovations, as well. Based on three adopter groups of Battery Electric Vehicles (Utilitarian Savers, Performance Seekers, and Green Technologists), the authors develop tailored measures for decision-makers in policy and management to foster the adoption and diffusion of Battery Electric Vehicles.
