In the aftermath of the 2011 Fukushima nuclear crisis, manufacturers have boosted exports of coal-fired thermal power equipment and systems, and received enough orders to build facilities with a combined generating capacity of 20 million kw, equivalent to the output of 20 nuclear power plants, trade ministry data showed Saturday.

Japanese companies make efficient coal-fired thermal power generation systems, which are in strong demand in Asia's emerging economies where more power is needed, as well as in Eastern Europe, where facilities need upgrading.

An increase of coal-fired thermal power facilities with a combined generation capacity of 270 million kw is expected in Asia and Eastern Europe.

Domestic manufacturers have a technological edge over their foreign rivals, thanks to their supercritical pressure technology.

The government is supporting the export of coal-fired thermal power equipment and systems and plans to incorporate the policy of promoting such power in Japan's growth strategy.

About 40 percent of the world's electricity is generated from coal-fired thermal power because of its low cost, which is about one-third that of liquefied natural gas. But coal power is said to produce about 1.5 times more carbon dioxide, which causes global warming, than LNG, prompting Japanese makers to develop technology that is safer for the environment as well.

Based on data from the Ministry of Economy, Trade and Industry and other sources, more than 15 orders for equipment such as coal-fired thermal power boilers and turbines have been received from seven countries and areas.
