Hydrogen and fuel cell technologies may represent a key enabling 
technology for radio base stations (RBSs) powered by renewable energies 
to see real market traction. The EU-funded project 'Demonstration 
project for power supply to telecom stations through FC technology' (
FCPOWEREDRBS)
 is clearly demonstrating this potential. With 15 RBS installations live
 in Italy and 2 in Europe research centres, FCPOWEREDRBS is conducting 
field trials to allow a complete technology assessment for this 
promising, yet early market.
These units should demonstrate such performance in terms of start-up
 time, reliability, durability and number of cycles that should qualify 
them for quick market entry throughout the world.
Diesel generators are being displaced by new systems combining 
renewable energy and proton exchange membrane fuel cells fuelled with 
pure hydrogen. With such alternative fuelling solutions, FCPOWEREDRBS is
 not only enhancing off-grid RBS performance but also decreasing cost of
 ownership.
Several simulation activities helped define system specifications. 
Focus was placed on evaluating the impact of the battery and the 
photovoltaic pack sizes as well as of the variable weather on the system
 output. A laboratory for benchmarking of fuel cell-powered RBSs was set
 up, where also the first fuel cell system was tested. Furthermore, 
researchers verified the impact of sudden radiation variations on each 
sub-system.
FCPOWEREDRBS has developed a benchmark protocol for the fuel cell 
technology that should be added to the available benchmark protocols, 
providing a point of reference for final users.
The FCPOWEREDRBS project's proposed fuel cell solution reduces RBS carbon footprint and offers significant cost savings.
