Ministers and delegates from more than 30 nations, regions and organizations pledged Wednesday in Tokyo to introduce 10 million fuel cell vehicles, trucks, buses and other hydrogen-powered systems, as well as 10,000 hydrogen refueling stations, globally over the next 10 years.

That means around a 250-fold increase over the next decade, as the current number of fuel cell vehicles, forklifts, trains and ships is estimated to be around 40,000 globally, said Yoshinori Furukawa, director general of New Energy and Industrial Technology Development Organization's advanced battery and hydrogen technology department.

That comprises about 10,800 FCVs across Japan, the United States and Germany, 3,000 fuel cell buses and trucks in China, and about 25,100 forklifts in Japan and the U.S., he added.
