Hydrogen Fuel Cell Technology
A hydrogen fuel cell generates electricity through an electrochemical reaction between hydrogen and oxygen. Unlike internal combustion engines, the only by-product is water vapour, making the system a zero-emission propulsion option. The generated electricity drives electric motors, and excess energy is stored in onboard batteries for use during acceleration peaks.
- Hydrogen is stored at high pressure (up to 350 bar) in lightweight carbon-fibre cylinders.
- The efficiency of hydrogen fuel cells is typically 40–60%, compared to around 20–30% for diesel engines.
- The trainset under development has a projected capacity of 2,400 kW and can carry roughly 2,600 passengers per rake.
- Unlike battery electric trains, hydrogen trains can be refuelled in minutes, similar to diesel.
