“…In general, previous studies have discovered the general sense of purpose of RES integration and relating EV diffusion [8], quantified the reduction in CO2 emissions and RES curtailments [9], deduced optimal levels of EV and RES penetration [10] and designed mechansims for the incentivisation of those [11].…”

Electric vehicles, being able to reduce pollutant and greenhouse gas emissions and shift the economy away from oil products, can play a major role in the transition towards low-carbon energy systems. However, the related increase in electricity demand inevitably affects the strategic planning of the overall energy system as well as the definition of the optimal power generation mix. With this respect, the impact of electric vehicles may vary significantly depending on the composition of both total primary energy supply and electricity generation. In this study, Italy and Germany are compared to highlight how a similarity in their renewable shares not necessarily leads to a CO2 emissions reduction. Different energy scenarios are simulated with the help of EnergyPLAN software assuming a progressive increase in renewable energy sources capacity and electric vehicles penetration. Results show that, for the German case, the additional electricity required leads to a reduction in CO2 emissions only if renewable capacity increases significantly, whereas the Italian energy system benefits from transport electrification even at low renewable capacity. Smart charging strategies are also found to foster renewable integration; however, power curtailments are still significant at high renewable capacity in the absence of large-scale energy storage systems.

“…A reference scenario has been modelled with reference to the Italian energy system at 2016 with help of EnergyPLAN software, a computer model for energy system analysis. Data have been derived from updated and reliable sources following the procedure used in previous works of the authors [31]. Input data relevant to the analysis have been summarised in Appendix A listing main input parameters described in the following.…”

“…For example, Varone and Ferrari analysed the German energy scenario and pointed out that an eightfold increase in RES capacity, together with the adoption of P2G technologies, could result in a 79% RES share of total electricity generation [34]. In the Italian case, Romanelli estimated that, if RES were to generate an annual electricity production equal to the annual amount of electricity demand, RES capacity was required to increase, above the 2013 level, by a factor of 7.5-8.5 [2], while the authors found that full electrification of private transport and a tenfold increase in iRES capacity only result in 20% emission reduction and 58% RES share of electricity generation if no other measure is implemented [31].…”

“…From demand side, EV are assumed to replace conventional light-duty vehicle fleet by 50% and 100%. The procedure implemented for the replacement of conventional cars follows what is reported in a previous study by the authors [31]; vehicles operating parameters are derived as a weighted average from the actual fleet, taking into account real-driving conditions and auxiliary consumption [37,38]. An example, referring to a 50% replacement of the conventional fleet, is recalled in Tables 3 and 4.…”

Storage technologies are progressively emerging as a key measure to accommodate high shares of intermittent renewables with a view to guarantee their effective integration towards a profound decarbonisation of existing energy systems. This study aims to evaluate to what extent electricity storage can contribute to a significant renewable penetration by absorbing otherwise-curtailed renewable surplus and quantitatively defines the associated costs. Under a Smart Energy System perspective, a variety of future scenarios are defined for the Italian case based on a progressively increasing renewable and storage capacity feeding an ever-larger electrified demand mostly made up of electric vehicles and, to some extent, heat pumps and power-to-gas/liquid technologies. Results are compared in terms of crucial environmental and techno-economic indicators and discussed with respect to storage operating parameters. The outcome of this analysis reveals the remarkable role of electricity storage in increasing system flexibility and reducing, in the range 24–44%, the renewable capacity required to meet a given sustainability target. Nonetheless, such achievements become feasible only under relatively low investment and operating costs, condition that excludes electrochemical storage solutions and privileges low-cost alternatives that at present, however, exist only at a pilot or demonstration scale.

“…An additional aspect, that will be considered in detail, is the electricity production and distribution pathway: although electric cars are not causing local emissions, the electricity production may have other de-localized environmental impacts, especially if produced by fossil fuels. Focused studies are needed to promote synergies between EVs and a proper electricity generation from local RES (Bellocchi, Gambini, Manno, Stilo, & Vellini, 2018).…”

The transport sector has rarely seen disruptive evolutions after the diffusion of the internal combustion engine, and today the European mobility is still heavily relying on oil derivates and on private cars. However, there is a significant push in cities towards more sustainable mobility paradigms, and digital technologies are playing a major role in unleashing possible alternatives to a car-and fossil-based mobility. Three major digital trends can be highlighted, with different levels of maturity and some potential synergies among them: Mobility as a Service, Shared Mobility and Autonomous Vehicles. The effects of these trends are also related to the strong push towards electric mobility, which currently appears as the most supported solution by companies and regulators to decarbonize the transport sector. This working paper discusses an investigation of the potential effects of digital transition, by means of a data-driven model for the calculation of the impacts of mobility demand in Europe in terms of primary energy consumption and CO2 emissions. The results show that digitalization may have a positive effect on energy consumption and CO2 emissions for passenger transport, given the strong efficiency improvements expected by technological development in the vehicles powertrains. The benefits are maximized if digital technologies are used towards a collective optimization, by increasing the share of available mobility options. Conversely, if digital technologies are limited to increase the quality of private mobility, the environmental benefits will likely remain very limited. Thus, there is a need of tailored policies supporting the right mobility models to fully exploit the potential benefits of digitalization.
