Nokia Siemens Networks Company and Ballard Power Systems said that the fuel supply system on the base of methanol can be part of cellular base stations and maintain the health of the latter in the case of power failure. Test such developments Nokia Siemens and Ballard Power intend to in the near future on the network as an example of Japanese mobile operator NTT DoCoMo. In NSN say that most of today's cell towers initially have no spare power supply systems, except full-time.
Some stations are equipped with optional generators or batteries. However, the new power system more friendly to the environment, in the quieter and more economical in comparison with diesel fuel. In addition, the methanol system by its dimensions are smaller and lighter than conventional generators. As described in the Nokia Siemens Networks, the proposed concept of the methanol supply to the cell tower has power to provide power for about 40 hours on one tank of 225 liters of liquid methanol, which is about 5.6 liters of methanol per hour. Diesel generator uses about 3 liters / hour but a direct comparison here is incorrect, assure of NSN. Diesel generators require much more maintenance, and on its cost three times as much diesel fuel methanol. Another thing is the availability of methanol on the market today. For example, in Japan, with the availability of methanol, no problem, but in other countries it is. Engineers say that as soon as NTT DoCoMo set several CSs in a methanol fuel supply and will test them on one of the segments of their networks. At Nokia Siemens says Japan over other parties interested in solutions for critical infrastructure that supports backup power, but in the current conditions almost everywhere there is the feasibility of similar systems.Expected from testing Nokia Siemens and NTT DoCoMo signed a commercial agreement to equipment supply.
Earlier Japanese manufacturer ROHM Semiconductor announced the development of a hydrogen battery, with which you can charge smartphones and tablets, if not in the availability of stationary supplies.
