UK project achieves 97% diesel-free operation

Network Rail and Colas Rail say they have proven the viability of sustainable construction, by operating a 97% diesel-free “site of the future”.

The companies used innovative solar lighting and power generation to support a major rail renewal project in Llanwern, South Wales.

During the 14-day trial, two 25 kW solar generators, supplied by UK-based renewable power specialist Prolectric, replaced conventional diesel generators, saving 6,000 litres of fuel.

More than 15 tonnes of CO₂ was also saved using Prolectric’s range of solar and battery technologies for lighting and heating throughout the site.

The results of the trial are being hailed as a significant achievement and could help move Network Rail towards its target of reducing non-traction energy consumption by 20% and carbon emissions by 25%.

Ryan Ballinger, production manager for Colas Rail, said, “A 97% diesel reduction at the first attempt is a great achievement. Saving close to 6,000 litres of diesel is the same as driving a family car at 40 mpg twice around the circumference of the world.

“There’s no doubt these technologies are going to be a complete gamechanger and we need to push on to get to a place where using this type of technology is just business as usual.”

Balinger said the companies’ aim was to achieve a 100% fuel-free site by the time of the next trial, set for a rail renewal project later this year.
