Japan's Economy, Trade and Industry Ministry says it will support companies that invest in geothermal power generation projects.
Geothermal generation uses high-temperature steam produced by underground water heated by volcanic activity. The ministry predicts that geothermal generation will be a key source of renewable energy in Japan, which has many volcanoes.
A semi-governmental body will offer grants or investment money to firms looking for suitable sites.
Companies need to raise huge amounts of money for the initial stages of these projects. Drilling a well for underground steam is said to cost 5 to 10 billion yen, or 65 million to 130 million dollars. The ministry also plans to guarantee firms' debt to help them obtain loans for the projects from financial institutions.
