ElectroSelf Guarantees Power to a High-Speed Internet System using Renewables
14 Feb 2012
Electro Power Systems SpA (ElectroPS), based in Turin, has deployed its ElectroSelf ‘self-recharging’ back-up power fuel cell unit within an agile energy system based on solar and wind power. The system has been fully designed and built by ElectroPS.
The system provides 24 hour back-up power for a new WiMAX antenna that brings broadband internet to a rural area in Italy; Cellarengo has to date found network connections difficult to establish and high-speed connectivity near impossible.
The energy system comprises a photovoltaic system and a mini-windmill with the ElectroSelf, which combines a fuel cells and an electrolyser. The electrolyser generates hydrogen from water during periods of excess energy supply, and the fuel cell uses the hydrogen for production of electricity during periods when demand outstrips supply, in turn producing water for the electrolyser.
This use of fuel cell and electrolyser technology facilitates clean distributed generation and increases the value of small-scale renewables by minimising the mismatch between energy production and consumption.
