Technology:
The move
to use cheap surplus electricity for mass production of hydrogen by electrolysis
of water and use the produced hydrogen as a source of energy of power
generation as needed is expected to spread. That is, hydrogen will play a role
of a battery. Kawasaki Heavy is ahead of others in this move, and it is
negotiating on a project to liquefy hydrogen with the Russian leading electric
power company RusHydro headquartered in Oblast Magadan
near Polustrov Kamchatka. Because surplus electricity generated by hydraulic
power generation is very cheap, it will be possible to supply liquefied hydrogen
to Japan at a low cost. The company plans to start the demonstration experiment
in Russia in 2017, and subsequently build a large-scale plant with an annual
production capacity of 90,000 tons with an investment of 20-30 billion yen.
It wishes to market liquefied hydrogen imported
form Russia as fuel for power generation. Development of the technology to
liquefy hydrogen using cheap nighttime electricity will open up the road to use
liquefied hydrogen as fuel for daytime power generation. Theoretically, it will
also be possible to transport and store hydrogen produced by electrolysis of
water using cheap electricity generated by photovoltaic generation in such hot regions
as the Middle East and Africa. It is expected that spread of hydrogen power
generation will contribute greatly to the spread of renewable energy.
