Plans for the the largest tidal power turbines in the world have been unveiled by the UK’s SIMEC Atlantis Energy.
The UK company’s ‘next generation’ single axis rotor turbine would be capable of accommodating rotor diameters of between 20-24 metres, depending on the site, while only reducing rotor speed by less than one metre per second.
For a machine with a 20-metre rotor, that would mean a maximum power output of 2MW at 3.05 metres per second. It is designed to be the backbone of a highly efficient and cost-effective generation system.
The turbine is offered as part of a complete rotor to grid tidal generation system, with an array architecture that allows multiple turbines to be connected in parallel, reducing the cost and impact of the subsea infrastructure.
The AR2000 turbine has been in development for two years and builds on the deployment of the firm’s AR1500 turbines at the MeyGen project in Scotland, which began generating power for the grid last year. The new 2MW turbines are expected to be deployed on future phases of the MeyGen project and will be also be available for sale to commercial developers late next year.
Drew Blaxland, director of turbine and engineering services at SIMEC Atlantis Energy, said deployment of the AR2000 would help reduce costs and deliver efficiencies for the tidal power sector.
“Combining a larger rotor diameter with a drive train capable of being daisy-chain linked, optimised redundancy and quick connection, will deliver an offshore generation system that can compete with other comparable sources of renewable generation when deployed at scale.”
“Not only will it be the largest single rotor turbine in production, it will be the backbone of a highly efficient and cost-effective generation system capable of deployment in each of our key target markets in the UK, France, Channel Islands, Asia, Australia and Canada,” he explained.
