Officials from around the world have agreed to support a sharp increase in hydrogen technology. Japan announced Wednesday that energy ministers or delegates from 30 countries are supporting a plan to develop hydrogen energy for transportation. The Japanese government invited the officials to the Hydrogen Ministerial Meeting in Tokyo. The 30 countries reportedly agreed to calls to increase production of hydrogen-powered mobility systems, such as fuel cell vehicles, trucks, buses, trains or ships. The goal is to make 10 million such systems available worldwide over the next 10 years.
