A company which has devised an innovative way of allowing cars to run on hydrogen has won a green award.

Staff at OM Energy, based at Aston Tirrold, have invented an Electro Hydrogen Generator which converts water stored in the car to hydrogen that is then fed back into the engine, cutting the amount of petrol or diesel used. The technology has won a Shell Springboard award of £20,000.

OM Energy is now waiting to hear if it would be named as the overall UK winner.

Director Don Smith said: "This will help to secure the financial future of the company, while the recognition will increase our credibility in the industry. We can now talk to engine companies and truck manufacturers with greater confidence."

Andrew Eddy, director of Shell UK, added: "This kind of grassroots innovation from within the small business community will play a critical role in tackling climate change."
