Ambitious plans for the large-scale deployment of wave and tidal energy are underway to meet carbon reduction targets, with up to 240 GW (gigawatts) of marine (188 GW wave and 52 GW tidal) energy generation capacity forecast by 2050. 1 Test sites, including the European Marine Energy Centre (EMEC), have been established, seabed leases have been awarded, and the deployment of the first, small-scale, commercial array of devices is underway at the Meygen development in Scotland. Plans for significant ocean energy (OE) developments, including up to 1.6 GW of wave and tidal energy generation planned for the Pentland Firth and Orkney Waters (PFOW) in Scotland, are emerging, with test sites being established around the world. 2
