Nautricity, Aquamarine, Ecosse Subsea, Orkney’s European Marine Energy Centre, Iberdrola and Carnegie, etc, share in £7m Scottish Wave Energy contracts bonanza

Wave power general2 HWUScottish wave power developers – as well as peers and rivals from Australia, the EU and the USA – are among 16 global suppliers to share in a £7 million contracts bonanza announced today by Wave Energy Scotland.

Scotland’s national wave energy incubator is focused on the development of low cost, efficient and reliable components and subsystems that can be shared by wave energy technology developers. 

Contracted amounts range from £78,000 for concept optimisation to up to £2 million for later stage prototype development.

Each successful project has been awarded up to 100% financial support for their technology development projects. 

Scottish Energy Minister Fergus Ewing – who set up the incubator last year following financial crises affecting domestic wave power companies – said today: ‘‘This is a hugely significant day for Wave Energy Scotland – which is running the biggest technology programme the wave sector has ever seen. 

“Since the launch last year, there has been global interest in what the new organisation was planning to do.

“Therefore I am delighted to see the first contracts being awarded to technology developers.   Scottish businesses are involved in the overwhelming majority of the projects and this is testament to the number of innovative companies operating in Scotland.

 “The Scottish Government is committed to supporting this important sector and we are confident that Scotland will continue to hold its world class status as a thriving country for wave energy technology development.”
