Nokia Siemens Networks and Ballard Power Systems are collaborating on a fuel cell system that could provide extended electrical backup to a cell site during an emergency.
The companies cited a number of advantages to fuel cell over battery back-ups or diesel generators. These include higher reliability across a wide range of operating conditions, lower maintenance costs, longer operating life as well as reduced size, weight, installation footprint, noise signature and environmental impact.
The base station and fuel cell combination developed by Nokia Siemens Networks with Ballard can provide 4.5 kW of power for approximately 40 hours on a single tank of fuel.
NTT DOCOMO is testing the system alongside the Nokia Siemens Networks Flexi Multiradio base station at Yokosuka Research Park (YRP) for potential commercial deployment.
The solution from Nokia Siemens Networks and Ballard Power Systems has already received the Ministry of Economy, Trade and Industry (METI) statutory approval in Japan.
“Mobile networks can be vital when a natural disaster strikes, and power outages make other forms of communication difficult,” said Mark Donaldson, head of energy solutions for mobile broadband networks at Nokia Siemens Networks. “Integrating fuel cells with our base stations can significantly increase the resilience of the mobile networks we provide.”
“Our fuel cell systems provide power for extended periods during outages caused by natural calamities and commercial grid failures,” said Larry Stapleton, vice president of sales, Ballard. “The collaboration with Nokia Siemens Networks has helped us leverage our service and integration expertise in order to deliver an emergency-ready alternative power solution for mobile networks.”
