New technology aims to cut emissions

His comments came as a Dundee and Aberdeen-based company unveiled details of a new type of battery which aims to increase electric vehicle efficiency.

The project is being developed by Axeon in conjunction with another company, ITI Energy, also based in Aberdeen.

Mr Stephen said Scotland aimed to be a world leader in alternative technology.

It is hoped the new Li-ion system will offer an emission-free, cheaper alternative to current technology and be used to power a range of vehicles, from golf carts to buses.

'Rapidly growing market'

Mr Stephen said: "If Scotland is to be energy self-sufficient in the long run, it is vital that we make the most of our vast renewable resources.

"It is equally important that we continue to develop various forms of alternative technologies - and on both fronts we aim to lead globally in moving towards green and clean energy."

Mr Stephen, who described the Li-ion project as a significant step forward for Scotland's energy future, added: "The increased proliferation of electric vehicles in our towns and cities is an indicator of some progress."

Axeon chief executive Hamish Grant said new battery technology and electronics were fuelling a rapidly growing market for electric and hybrid electric vehicles.

"These vehicles can make a significant contribution to reducing CO2 emissions while reducing operating costs for their operators," he said.
