Potential Climate Impact Variations Due to Fueling Behavior of Plug-in Hybrid Vehicle Owners in the US

Abstract

With the expected rapid growth of renewable electricity generation, charging plug-in hybrid electric vehicles (PHEVs) from the grid promise ever higher reductions in CO 2 emissions. Previous analyses have found that the share that PHEVs are driven in electric mode can differ substantially depending on region, battery size, and trip purpose. Here, we provide a first fleet-wide emissions mitigation potential of US-based PHEV drivers adopting high or low shares of electric driving. Specifically, we illustrate scenarios of different combinations of PHEV uptake, renewable electricity generation shares, and PHEV fueling behavior. Across 21 analyzed scenarios, annual greenhouse gas (GHG) emissions of the light-duty vehicle (LDV) fleet could differ by an average of 21% (5–43% range) in 2050 depending alone on the fueling behavior of PHEV drivers. This behavior could further determine the discharge of about 1.3 (0.7–1.9) Gt CO 2 (or roughly one year of current emissions) over the next three decades, significantly influencing the feasibility of reaching an 80% emission reduction target for the LDV sector. Governments can nudge PHEV drivers toward environmentally favorable fueling behavior. We discuss several options for nudging, including charging infrastructure availability, battery design, and consumer education.

Greenhouse gas emissions of India's household food, apparel, mobility and energy consumption: Regional structure and inequality, and scenarios for 1.5°C climate stabilization

“…Additionally, to explore the capabilities of developed regional commod-ity and carbon-database of 2011-12, we model scenarios aimed at net-zero emissions by 2050 for specific products identified through this "bottom-up" assessment, with the exclusion of rebound effects. The explored scenarios are in alignment with #SDGinPB framework [2], and demonstrate the poten-tial reduction of "direct" households emissions from both supply-side [40] and demand-side [41,42] actions, considering per capita-based share of global carbon-budgets [11,43] in view of planetary-boundaries [44]. Further, the transitions explored in these scenarios are interpreted and justified under the "Avoid-Shift-Improve" framework [45,46].…”

“…Neither does hydrogen-based mobility guarantee such a low-carbon state for all [116]. Thus from a demand-side emissionreduction perspective, apt changes in consumer-behavior [42], increasing material-efficiency [117], reduc-tion in residential-energy demand [118] from fair building space distribution [119], etc. should also be foreseen as possible solutions.…”

“…The above defined scenarios are explored to quantify potential and definite emission reductions that can be achieved through both production-system (electricity) and behavioral changes, however the defined scenarios are not exhaustive. Other scenarios others such as those focusing on expenditureand age-stratified behavioural-changes [85,86], regional-densification [87], fueling-behaviour [42] in conjunction with adoption of electricity-vehicles, can be GHG Indian households: Structure, Inequality and Scenarios explored as well. Further, we excluded assessment of vehicle electrification (bat-tery electricity-vehicles (BEVs) or hydrogen-based vehicles(HbVs) [88,89]) impacts since it is already been proven that without greener grid GHG reduc-tion would not happen [90].…”

Energy Consumption Prediction and Control Algorithm for Hybrid Electric Vehicles Based on an Equivalent Minimum Fuel Consumption Model

“…The energy crisis and environmental pollution are becoming more and more serious, and hybrid electric vehicles have gradually become a key topic in the field of automobile research because of their low energy consumption and low emissions [1,2]. Hybrid electric vehicles refer to vehicles whose driving systems are composed of two or more single driving systems that can run at the same time, and the driving power of these vehicles is provided by a single driving system, alone or jointly, according to the actual driving state of such a vehicle [3].…”
