Telecommunications company Orange has begun trials with a telephone mast powered by a hydrogen fuel cell.
Orange said electrical cabling would have been damaging
The company has installed the system on a mast at the Huntly Nordic Ski Centre site in Aberdeenshire.
It said the stand-alone power unit was an environmentally friendly alternative to the laying of five kilometres of cabling at the site.
A spokesman said the cabling work would have caused environmental damage and would have proved much more costly.
Orange said its fuel cell was supported by a back-up LPG generator.
The mast is situated in forest land and provides network coverage for the A941 road between Rhynie and Elgin.
Ian Guthrie, the company's operations manager in Scotland, said: "This breakthrough means we will be able to look at getting network coverage to those areas not covered at this present time.
"We were also pleased to have been able to do this in a cost-effective way as well as creating as little environmental damage as possible to the surrounding area."
Norman Davidson, district manager for Forestry Commission Scotland, said: "The technology means there has been no impact on the forest and it is something we will be looking at further to provide power to installations we need to run in our remote areas."
Ski club secretary Peter Thorn said an oil generator or cabling would have had a negative impact on the site and the club now has full network coverage which would prove beneficial should an accident happen.
The system was installed in December and is subject to a six-month trial.
