摘要：SummaryWe employed a bottom-up modeling framework to examine a set of scenarios to generate insights on the techno-economic and environmental implications of increasing levels of electric vehicle (EV) penetration using Nigeria as a case study. Results indicate that, despite Nigeria having a natural gas-dominated electricity system, the deployment of EVs can support the decarbonization of the transportation and power sectors but at a relatively high cost. The cost of EVs would need to drop by ∼40% to become cost-competitive. However, if variable renewable energy sources deliver the EVs power requirement with a bidirectional vehicle-to-grid (V2G) charging strategy, then the cost of EVs would need to decline by only ∼30%. Not all EVs need to participate in a V2G charging strategy in order to realize the full benefits of the strategy. Expanding renewables capacity leads to additional reduction in CO2emission and decarbonization cost but at different magnitudes based on the charging strategy.Graphical abstractDisplay OmittedHighlights•Deploying EVs in Nigeria could support decarbonization•V2G charging of EVs lessens pressure on Nigeria’s energy sector investments•High EVs penetration is cost-effective with variable renewable electricity•Benefit from V2G is achieved at relatively modest deployment levels of EVsEnergy policy; Energy sustainability; Energy Resources; Energy transportation; Energy storage
