Abstract
Expanding energy resources for electric power plants from fossil energies to cost competitive renewable ones are required
for reducing GHG emissions and for coping with the soaring in imported fossil energies prices. Importing natural energy
resources as storable and transportable hydrogen transformed from wind power electricity may be preferable. If windmills of
large quantity are constructed in the favored oversea regions, where steady and strong wind is blowing over wide area and the
electricity cost becomes low.
Although it is difficult for hydrogen from overseas wind power generation to show economic efficiency in terms of calorific
value compared to present fossil fuel prices, it was suggested that in the future, it would be more economical to stop using
existing oil-fired thermal power stations and mix LNG with hydrogen at existing LNG power stations. As a means to reduce
CO2, it was also suggested that it would be more economical to mix LGN with hydrogen at existing LNG power stations if
other power generation-related means exceed 7,000 yen/t-CO2
