The sales of hydrogen fuel cell trains will generate a cumulative revenue of $653.6 billion over the next 15 years. During this period, the unit sales of these trains, also known as hydrails, will grow at a CAGR of over 100 percent.

A locomotive's normal lifespan is 30 years, but with proper maintenance, it can exceed 40 years. This means that when investing in a locomotive, one has to carefully weigh the pros and cons.

The train vendor currently spearheading the market is Alstom, but several other train manufacturers are making waves in the market. The market will dramatically expand as more players enter the market.

Over 30 countries are in various stages of deploying fuel cell trains, most of them in Europe. But over the next 15 years, Asia-Pacific will overtake Europe in both terms of unit sales and revenue.

Because of its high energy density by weight, hydrogen is ideally suited for heavy-duty trains. Currently, battery-electric trains are less expensive than hydrails. But for heavy-duty applications, hydrogen is a much better solution than batteries because batteries are poor energy storage devices.
