Coal is the cheapest option to generate the power at the moment. However, there are some crucial supports will be required even if some new technology has been developed to reduce the environmental impact.
J-Power also owns Osaki Coolgen, a 170 megawatt IGCC pilot plant near Hiroshima, where carbon capture - but not storage - will be demonstrated from 2019. Japan lacks suitable sites for storage, and is concentrating on ways to re-use the carbon for enhanced oil recovery or production of algae for biofuel and fertiliser.
Commercial implementation "depends on performance and capital cost," J-power said.
Is anyone can support to solve these problems from the coal supply side??
