Engineering & maintenance specialist FDT is demonstrating the versatility of an environmentally-friendly power generation source that runs on hydrogen, produces no noise and the only emissions are heat and water.

The company is one of the UK's leading experts on using hydrogen fuel cell technology to provider electrical power in remote locations.

The hydrogen fuel cell produces no noise because unlike diesel or gas generators the fuel cell converts the hydrogen directly into electricity without the need for combustion or the moving parts normally found in generators and combustion engines.

John Peake, managing director of FDT, said: "This technology is available and suitable for real applications and we chose to set up the laser show in London to demonstrate that the technology can be used in a wide range of applications.

"This is not a laboratory demonstration and we are already trialling the use of fuel cells as a back up power source for mobile phone masts."
