Schemes designed to help provide a source of renewable cheap energy have today been given extra funding from the Carbon Trust.
Two marine energy projects will benefit from a total of £400,000 of investment from the trust.
The Pelamis project, an electricity-generating 'sea snake' generating wave power, will benefit from extra cash to help investigate how to move the structures to effective locations and how to control the technology.
Marine Current Turbines will also receive cash from the trust to help it find a way to deploy its SeaGen tidal energy system.
Both developments should allow the projects to come closer to commercial reality, the Carbon Trust believes.
"Innovation in the deployment and maintenance of wave and tidal devices will be critical in cutting the cost of marine energy and unlocking the potential of this fantastic renewable energy source," said Mark Williamson, director of innovations at the Carbon Trust.
Earlier this week, the Carbon Trust highlighted the cost to UK businesses of waiting until equipment has broken before replacing it.
