NTT DoCoMo will use fuel cells at cellphone base stations across the country as emergency power sources in the event of a disaster.
Company officials from Japan's largest mobile carrier said on Friday at the moment, only one in Tokyo has fuel cells, The Japan Times reported. Fuel cells generate power by combining hydrogen with oxygen in a chemical reaction and do not emit carbon dioxide.
However, Japan's largest mobile carrier will select other base stations by the end of this year for the introduction starting 2014, the officials noted.
The telco is also installing solar power systems at selected base stations and is planning to use solar power on a routine basis to reduce power consumption at the base stations.
Other than NTT DoCoMo, Softbank is also collaborating with U.S. fuel cell developer Bloom Energy to prevent potential communications failure from a blackout and promote environmental measures, a separate report on The Japan Times noted.
