日本語
本研究は、2018年から2050年までの屋上太陽光発電（PV）、電気自動車（EV）、Vehicle to Home（V2H）の段階的導入が都市エネルギーシステムに与える影響を、シナリオベースで年次評価する枠組みを提案する。吹田市を対象に、CO2削減、コスト削減、自家消費、エネルギー充足度、自立度の5指標を分析。加速シナリオでは2050年までにCO2を60%削減し、コストを25%以上削減可能で、2035年以降はPV単独よりPV・EV・V2H統合が効果的と示した。
English
This study proposes a scenario-based framework to quantify year-by-year impacts of gradual rooftop PV, EV, and V2H deployment from 2018 to 2050. Using Suita City, Japan, it assesses five dimensions: CO2 reduction, cost savings, self-consumption, energy sufficiency, and self-sufficiency. An accelerated scenario achieves up to 60% CO2 reduction and over 25% cost savings by 2050, with integrated PV-EV-V2H outperforming PV-only from around 2035.

📄 Abstract（原文）
Achieving carbon neutrality toward 2050 requires not only the adoption of renewable energy technologies but also long-term planning based on their gradual integration into urban systems. This study presents a novel scenario-based framework that quantifies year-by-year impacts of deploying rooftop photovoltaics (PVs), electric vehicles (EVs), and Vehicle to Home (V2H) systems from 2018 through 2050. Five key dimensions are assessed: CO2 emission reduction, cost savings, self-consumption, energy sufficiency, and self-sufficiency. Using Suita City, Japan, as a case study, we analyzed two diffusion scenarios, “baseline (current growth case)” and “accelerated deployment case”. The results indicate that despite high initial investment, an accelerated scenario can achieve up to a 60% CO2 emission reduction and over 25% cost savings by 2050. Importantly, the integrated deployment of PVs, EVs, and V2H surpasses PV-only systems in overall effectiveness from around 2035 onward. By capturing the dynamic evolution of technology impacts over time, this study provides unique and actionable insights for designing data-driven policies supporting long-term urban decarbonization.
