The European Marine Energy Centre (Emec) will showcase the pioneering work taking place in Orkney for European officials later this month.
European Commission representatives will be shown around Emec’s onshore facilities at the Billia Cross wave test site and the Caldale substation in Eday.
Their arrival coincides with an open day on June 28.
Both projects have received funding from Horizon 2020’s research and innovation programme.
Remi Gruet, chief executive Ocean Energy Europe, a network of marine power professionals, said: “We are delighted to bring a delegation of EU officials to Emec to see cutting edge ocean energy technologies in action.
“Europe is currently the global leader in ocean energy technology, and with the right support these technologies can form the bedrock of a mainstream power sector, capable of providing 10% of Europe’s electricity supply by 2050.”
