A small Orkney business is celebrating after winning £40,000 to help develop tidal energy.
Tidal power is seen as a way of reducing greenhouse gas
Scotrenewables won the award from an environmental fund called Springboard, set up by Shell UK to support ideas to combat climate change.
Awards are made for efforts that are innovative, commercially viable and that could lead to greenhouse gas reductions.
Scotrenewables received the money to help research tidal energy potential.
Stromness-based Scotrenewables managing director Barry Johnston said: "This is great news and a tremendous endorsement for our business.
"The funding from Shell Springboard will allow us to push forward our development plans for 2006 and beyond."
James Smith, chairman of Shell UK, said: "As demand for energy grows, so does the emphasis on governments and business to tackle climate change.
"So we set up Shell Springboard to encourage and reward companies with innovative ideas that are not only good for the environment but also good for business.
"This was the first Shell Springboard event in Scotland. It was a great success and proved small businesses really can make a difference."
Scotrenewables will now head to London on 7 March to compete with other UK businesses for a national award.
Formed in 2002, Scotrenewables has researched both wind and marine renewable energy.
