Mobile Phone Towers Double as Green Energy Stations

Mobile Phone Towers Double as Green Energy Stations

Cut-off communities across Europe pay more for electricity with greater cost to the environment because their tricky locations force them to rely on diesel generators.

But researchers have now found a way to supply them cheap, clean renewable energy by collecting and storing renewable energy from their mobile phone base stations.

It could bring cheaper, cleaner fuel to thousands in remote places like in mountains or on Europe’s many tiny islands and at the same time make them more self-sufficient.

Developed by Brunel University London and green energy tech firm,

SolarBotanic, Regenerative Hydrogen Fuel Cells (RHFCs) offer an environmentally-friendly way to store power from solar panels and wind turbines.

“Faced with unreliable power grids, or without a grid at all, telecom infrastructure companies want alternatives to high cost, high maintenance fossil fuels,” said Brunel’s Dr Zahir Dehouche, a sustainable energy specialist. “RHFC systems are the answer.”

The fuel cells use excess electricity from the solar panels and wind turbines to produce hydrogen from water. The hydrogen fuel is stored in a tank on-site and delivered to the fuel cells to generate electricity when needed, for instance when there’s not enough wind or solar power. This way, they cut out fuel used to transport the stored energy to these remote areas.

The system generates enough energy from solar panels and a wind turbine half way up the phone mast, to both power the mast and store to supply the community as a microgrid. The cells can supply power for 10 days and don’t need back up from a battery like diesel generators. They last longer than 15 years and are more secure and reliable than diesel systems backed up by battery and they are designed to blend in with the natural environment.

“This radical innovation provides the opportunity for a never-before-seen degree of energy autonomy, all the while significantly reducing cost, both financially and in terms of environmental impact”, said SolarBotanic’s Harry Corrigan.
