How to store energy in high-speed rail

Can high-speed rail save energy?

The research of Feng (2011) and Chiara et al. (2017) indicates that high-speed rail can realize the goal of energy saving and consumption reduction. HSR diverts traditional railroads' combined passenger and freight transportation, consistent with Lin et al. (2021) research.

Are high-speed trains energy efficient?

The energy efficiency of high-speed train moving between two successive stations is first studied, then we broaden our research vision in space and time until the global energy efficiency emergence of all in-service high-speed trains in the whole life cycle of railway transportation system can be understood.

What needs to be improved in energy-saving train operation?

In the current study, what need to be improved are as follows: 1. The energy consumption, rather than energy efficiency, was usually used to evaluate the effect of energy-saving train operation, which may be difficult to obtain the objective conclusions, especially in some cases such as the rapid increase or sharp decrease of transportation tasks.

What should China do about high-speed railway construction?

The government should thoroughly investigate the line planning stage, and give full play to the foresight and anticipation of the policy, to effectively enhance the “speeding up” effect of high-speed railway construction on energy efficiency and the development of China's green economy.

How does high-speed rail work?

On the one hand, high-speed rail's spatial and temporal compression can reduce transportation time and cost between cities and improve regional accessibility. It helps to break the regional restriction of factor flows and raise the allocation efficiency of resources, thus generating economic spillover effects (Chen & Haynes, 2017).

What is the energy consumption ratio of high-speed rail and automobile?

According to the statistics, the high-speed rail and automobile energy consumption ratio is 1:2.4 (Ginés, 2012). The shifting effect of passenger flow contributes to a significant reduction in the energy consumption of road passenger transport in urban transportation systems and improves energy efficiency.
