Engineers also focused on improving fuel efficiency and this results in a 20% increase in “cruising range.” While the current Mirai can travel 402 miles (647 km) between stops, hydrogen prices in California skyrocketed to record highs last year. This means any increase in fuel efficiency would be a welcome development.

Stationary fuel cells are gaining ground in the race to meet global energy security and decarbonisation goals. As the power grid faces mounting pressure from rising demands and digitalisation, fuel cells—especially those running on green hydrogen—are emerging as a viable solution.

For better or worse, Toyota is pushing ahead with the development of hydrogen powertrains, and it just revealed its third-generation fuel cell system as part of its “con
