Japan is primed following the 2011 Fukushima earthquake and tsunami to adopt more power supply devices that can withstand disasters and complement services provided by utilities, Bloom Energy Japan Ltd. said.

The country's fuel-cell market is currently led by individual users with small systems in their homes. Bloom Energy Japan is targeting larger power consumers such as office buildings, factories and data centers, said Shigeki Miwa, chief executive officer of the company.

"Utilities in the centralized power distribution system will remain the main player," he said. "But people have realized that is not enough. So it is good to have decentralized power distribution that can complement the system."
