Pure uses wind power to convert water to hydrogen
A Shetland renewable energy project has been shortlisted for a major international environmental award.

The Pure project, on Unst, is among the last three of the St Andrews Prize for the Environment, which carries a first prize of $50,000.

The project is the first off-grid renewable hydrogen system in Europe and the first community owned hydrogen production plant in the world.

It uses wind power to provide comprehensive and sustainable energy.

The other two finalists are a drinking water project in rural Nepal and a farming project in South America.

Innovative projects

Sir Crispin Tickell, chairman of the St Andrews Prize for the Environment trustees, said: "The prize is now in its eighth year and we are delighted that it has become so well established and continues to attract such a range of innovative projects from all over the world.

"We are very much looking forward to meeting the finalists and hearing about their projects in detail."

The Pure system enables wind generated electricity to convert water into hydrogen, which is then bottled and kept for converting back into electricity as required.

The winner will be announced in St Andrews next month, with each of the other finalists receiving $10,000.
