Principles of wave and tidal energy conversion

Our turbines have three different modes of operation: wave and tidal energy conversion; wave energy conversion; and tidal energy conversion. It is therefore possible for the potential energy of waves and the kinetic energy of tidal streams to be converted into electricity. They have a very low socio-environmental impact, are scalable and produce electricity at an industry-leading levelised cost of energy (LCOE).

Our floating structures are semi-submersible, utilising a taut mooring principle and anchor cable shock absorbers to minimise wave impact forces. This approach also eliminates the need for voltage-limiting inductive couplings and expensive subsea maintenance and defouling interventions, while reducing reliance on costly subsea construction techniques.

Our technology has a low environmental impact because:
• no piling is required to deploy the deadweight anchors or other components;
• only limited seabed trenching is required; and
• full recovery is planned during decommissioning.
