The integration of energy systems with highway infrastructure is gaining traction in China, particularly with the rise of new energy vehicles (NEVs). A recent study led by Li Zhang from the China Power Engineering Consulting Group Co., Ltd. highlights the significant potential for developing a Photovoltaic-Storage-Charging (PV-Storage-Charging) model that aligns transportation needs with renewable energy resources.
As NEVs continue to proliferate, projected figures indicate that by 2025, the national stock of these vehicles will exceed 25 million, consuming an estimated 37.5 terawatt-hours (TWh) of electricity. This surge in electricity demand necessitates innovative solutions to ensure that highways can support the energy needs of these vehicles while also promoting sustainable practices.
The study emphasizes the abundant photovoltaic resources available along China’s highways, with an estimated generation potential of around 1022.8 terawatts (TW). In contrast, the annual energy consumption for highway infrastructure is approximately 17.99 TW. This discrepancy underscores the opportunity to harness solar energy to not only meet the growing demands of NEVs but also to alleviate pressure on the national grid.
Zhang’s research advocates for a self-consistent energy system that leverages these resources. “The main path of integration between transportation and energy should start with developing wind and photovoltaic natural resource endowments based on the infrastructure of road transportation itself,” he states. This approach aims to create a distributed, green, and renewable energy supply system that can operate independently of traditional grid systems.
The commercial implications of this integration are substantial. By investing in PV-Storage-Charging infrastructure, companies can capitalize on the growing market for NEVs while contributing to the reduction of greenhouse gas emissions. The potential for local renewable energy consumption not only enhances energy security but also opens avenues for businesses to participate in the clean energy transition.
The findings of this research, published in “Southern Energy Construction,” provide a theoretical foundation for advancing highway transportation and energy integration in China. As the country continues to prioritize sustainable development, the integration of renewable energy into highway systems represents a promising frontier for the energy sector, paving the way for innovative solutions that benefit both the environment and the economy.
