Smart Integration of Renewable Energy into Transportation: Challenges, Innovations, and Future Research Directions

Abstract

The integration of renewable energy into transportation systems is essential for reducing greenhouse gas emissions and achieving global  sustainability goals. This review explores the challenges, innovations, and future directions of incorporating renewable energy  sources such as solar, wind, and bioenergy into transportation infrastructures. Key challenges include the intermittency of renewable  energy, the need for advancements in energy storage systems, and the regulatory and economic barriers hindering widespread  adoption. Innovations such as electric vehicles (EVs), vehicle-to-grid (V2G) technologies, and smart grids are pivotal in enabling this  transition. Furthermore, artificial intelligence (AI) and machine learning (ML) offer significant potential to optimize energy management,  enhance efficiency, and facilitate the smooth integration of renewable energy with transportation systems. The review also discusses  successful case studies from different regions and examines policy frameworks supporting renewable energy in transportation. Future  directions point toward increased collaboration between industries, technological advancements, and supportive policies to create a more sustainable, resilient transportation sector. Ultimately, this review aims to provide a comprehensive understanding of how smart  integration of renewable energy into transportation can drive a cleaner, more sustainable future.
