The Japanese government is set to build up to 45 new high energy, low emission (HELE) coal-fired power plants in a bid to diversify its power supply.
Following Fukushima, the country had favoured gas-fired power, with liquefied natural gas being imported, but has opted for coal, as gas has risen in price.
The coal will to be used in the plants will be imported also from Australia and the island nation is heavily dependent on imports for its electricity security.
Tom O'Sullivan, a Tokyo based energy consultant with Mathyos Global Advisory, told ABC Online, "So it's trying to diversify its fuel sources and it doesn't want to be too reliant on any one market."
Coal power advocates say HELE coal fired power plants produce half of the emissions of traditional plants.
