Marubeni Targets National Park in Japan for Geothermal

Marubeni Corp., the biggest investor in electricity generation among Japan’s trading houses, is working on how to revive the geothermal industry and tap heat that powers volcanos as an alternative to nuclear reactors.
The effort would draw pools of underground heat with a potential of double the current capacity of geothermal projects operating worldwide. That would help Japan shift away from atomic reactors that provided 30 percent of the nation’s power before the accident in Fukushima two years ago.
