Residents and visitors to Valcamonica, an Alpine region in northern Italy, will be able to ride hydrogen-powered trains from next year. The region currently uses polluting diesel trains, which will be replaced by 14 zero-emission hydrogen-powered trains. The project, the first of its kind in Italy and supported by an investment of 367 million euros ($396 million), marks the adoption of hydrogen fuel for a rail line, despite the high production and operational costs.
