China's railway has been experiencing rapid growth recently. The achievement of solar energy for the increasing electricity consumption in the rail sector attracts significant attentions. In this paper, the available solar energy on the covered land and trackside land in the rail itself is assessed for further utilization.
Except for the railway tunnels, the available railway mileages for the integration of the solar power generation are decreased to 0.2 × 104 km in Zone I, 3.1 × 10 4 km in Zone II, 7.5 × 10 4 km in Zone III, and 1.1 × 10 4 km in Zone IV, respectively. Fig. 1. Distribution of railway networks and solar energy in China.
The lowest daily PV generation is 1334 MWh, which still covers 60% of the electricity consumption. These results indicate the high potential of the railway PV system to supply power to the HSR and show that the railway system is not highly reliant on the storage system, which undoubtedly cuts the system costs.
As seen, all the available solar energy in the rail sector itself is as much as 3157.8 TWh per year. Since there is less rail mileage in Zone I and IV, less utilized space is available for solar energy integration. The available solar energy in Zone I and IV are 79.8 TWh and 230.4 TWh, respectively, occupying 2.5% and 7.3% in the total.
In addition to accelerating the deployment of high-speed railways powered by electric traction, China also needs to transition from coal-fired power supply (Guan et al., 2018; Li et al., 2016) and use electricity from renewable sources to enhance the eco-friendliness of the railway system (Dalla Chiara et al., 2017).
In past years, China's railway network has experienced the rapid growth. By the end of 2019, the total rail mileage exceeds 13.9 × 104 km . Since more and more electrified rails began operation, thereby resulting in a higher electrification rate, the electrification rate has a steady growth increasing to 71.9% in 2019.
