Two cutting edge marine energy devices are expected to rapidly speed up commercial development of wave and tidal power in the UK, it has been revealed.
The projects, which are being supported by the UK’s Carbon Trust are the Pelamis Wave Power and Marine Current Turbines. These focus on installation and maintenance, which currently account for up to 50% of the project costs of wave and tidal energy, according to the Carbon Trust.
Remote control technology will be integrated into existing systems, which will allow use in rougher seas, while the technology will decrease equipment and vessel requirements and enable quick and economical installation and maintenance, reducing the total cost of power produced.
The Carbon Trust is set to invest £250,000 in the Pelamis device.
The Carbon Trust will also invest £150,000 in a feasibility study on Marine Current Turbines (MCT) foundation technology, where a remotely operated subsea drilling platform fixes foundation piles before the deployment of the primary turbine support structure in a single unit.
If the technology meets expected performance targets, it will be utilised in SeaGen’s next project off Anglesey where the firm is collaborating with RWE npower renewables for a 10MW tidal farm, using seven SeaGen systems.
Carbon Trust director of innovations Mark Williamson said the technology will be vital in decreasing marine energy costs to tap the potential of wind as a renewable power resource.
