6 FAQs about [Hydrogen energy high-speed rail energy storage]

Should hydrogen fuel cell electric trains have liquid hydrogen storage?

For hydrogen fuel cell electric trains, a high volumetric storage capacity is more appealing for a long-haul operation. Therefore, in some cases, e.g., a hydrogen train project in South Korea, liquid hydrogen storage onboard was reported to be used .

How can hydrogen be used to power a train?

Hydrogen can be used to power trains via two means: combustion in engines that directly pass mechanical energy to onboard machinery , or oxidation in fuel cells (FCs) that convert chemical energy directly to electricity to power electric motors .

How do hydrogen-powered hybrid trains work?

For hydrogen-powered hybrid trains, the fuel cell systems provide the average load, while the battery systems cover the high peak power to assist traction and recover regenerative braking energy . In general, the design of hybrid power systems presents two key technical challenges: energy management strategies (EMS) and size optimization.

Could hydrogen fuel cell electric trains be a future transport system?

One rail route using hydrogen fuel cell electric trains has been commercialized. A variety of projects exist, but mostly in developed countries. Trains have been a crucial part of modern transport, and their high energy efficiency and low greenhouse gas emissions make them ideal candidates for the future transport system.

Why are sizing and energy management strategies important for hydrogen-powered InterCity trains?

5. Conclusions In summary, optimal sizing and energy management strategies (EMS) are essential for reducing fuel consumption, extending the lifespan of proton exchange membrane fuel cell (PEMFC) and battery systems, and improving the life cycle cost (LCC) of hydrogen-powered intercity trains.

How does a hydrogen-electric intercity train work?

The system setup and power flow of the traction system of a typical hydrogen-electric intercity train. During the traction phase, the train consumes energy from both the fuel cell and the battery. In the braking phase, the motor operates in regenerative braking mode, with part of the energy delivered to the battery system.
