“…The functional unit of this study is one vehicle kilometer traveled (VKT), which focuses on the operation phase of the vehicle's life cycle, and the associated system boundary from well-to-wheels (WTW). This WTW system boundary links the environmental impacts generated from well-to-tank (WTT), and tank-to-wheels (TTW), in order to more comprehensively compare BEV and ICEV emissions (see Figure 1) [31][32][33]. In the context of BEVs, the WTW boundary takes into account not only the emissions from electricity generation, but also emissions from extraction of the energy resources used for electric power generation, such as the emissions from extraction of natural gas, coal, oil, production of hydroelectric, nuclear, and solar photovoltaics (PVs) power sources [34].…”

The environmental impact of battery electric vehicles (BEVs) largely depends on the environmental profile of the national electric power grid that enables their operation. The purpose of this study is to analyze the environmental performance of BEV usage in Korea considering the changes and trajectory of the national power roadmap. We examined the environmental performance using a weighted environmental index, considering eight impact categories. The results showed that the weighted environmental impact of Korea’s national power grid supply would increase overall by 66% from 2015 to 2029 using the plan laid out by the 7th Power Roadmap, and by only 33% from 2017 to 2031 using the 8th Power Roadmap plan. This change reflects the substantial amount of renewables in the more recent power mix plan. In 2016, BEV usage in Korea resulted in emissions reductions of about 37% compared with diesel passenger vehicles, and 41% compared with gasoline vehicles per kilometer driven (100 g CO2e/km versus 158 g and 170 g CO2e/km, respectively) related to transportation sector. By 2030, BEV usage in Korea is expected to achieve a greater emissions reduction of about 53% compared with diesel vehicles and 56% compared with gasoline vehicles. However, trade-offs are also expected because of increased particulate matter (PM) pollution, which we anticipate to increase by 84% compared with 2016 conditions. Despite these projected increases in PM emissions, increased BEV usage in Korea is expected to result in important global and local benefits through reductions of climate-changing greenhouse gas (GHG) emissions.

Biomethane use for automobiles towards a CO2-neutral energy system

To pursue the goal of sustainable mobility, two main paths can be considered: the electrification of vehicles and the use of biofuels, replacing fossil fuels, in internal combustion engine (ICE) vehicles. This paper proposes an analysis of different possible scenarios for automobiles towards a CO2-neutral energy system, in the path of the use of biofuels and the production, distribution and use of biomethane. The study, an update of work presented previously, focuses on different scenarios that take into account numerous parameters that affect the overall efficiency of the production-and-use process. A Well-to-Wheel analysis is used to estimate the primary energy savings and reduction in greenhouse-gas emissions compared both to the use of fossil-based methane and to other fuels and automotive technologies. In particular, the study shows that the Non-Renewable Primary Energy Consumption (NRPEC) for biomethane is slightly higher (+9%) than that of biodiesel, but significantly lower than those of all the other power trains analysed: –69% compared to the battery electric vehicle (BEV) and –55% compared to bioethanol. Compared to the use of fossil natural gas, the NRPEC is reduced to just over a third (2.81). With regard to CO2 emissions, biomethane has the lowest values: –69% compared to BEV, –176% compared to bioethanol and –124% with respect to biodiesel. Compared to the use of fossil natural gas, the CO2 emissions are reduced over a third (3.55). Moreover, the paper shows that biomethane can completely cover the consumption of fossil methane for vehicles in Italy, proposing two different hypotheses: maximum production and minimum production. It is evident, therefore, that biomethane production can completely cover the consumption of fossil methane for vehicles: this means that the use of biomethane in the car can lead to a reduction in NRPEC equal to 28.9 × 106 GJ/year and a reduction of CO2 emissions equal to 1.9 × 106 t/year.
