Wave & Tidal Energy
Share |

The Department of Energy and Climate Change (DECC) estimates that wave & tidal stream energy combined has the potential to deliver around 20 per cent of the UK’s current electricity needs which equates to an installed capacity of around 30 – 50GW. In addition, tidal lagoons could deliver up to 8 per cent of our energy needs according to a recent report by The Centre for Economics and Business Research.

In their Marine Green Growth paper The Carbon Trust estimated that UK companies could capture around 22% of the global market for marine energy which could be worth around £76 billion between now and 2050.

Our Working for a Greener Britain and Northern Ireland report estimates that in the next decade wave and tidal stream energy could provide jobs for more than 20,000 people, contributing towards continued economic prosperity as we export our skills, services and products.

Ocean Energy Race Campaign

RenewableUK and our members have worked together to develop the Ocean Energy Race campaign (Member login required) in order to strengthen political support for developing wave and tidal energy in the UK. The strategic aim of the campaign is to harness support from MPs across the UK – as well as across political parties – to exert pressure on the Government to ensure there is a supportive framework for developing marine renewables. 

RenewableUK is a partner on the Marine Energy Supply Chain Gateway (MESCG) - a database of suppliers supporting the UK’s marine energy industry owned and managed by ORE Catapult. Members of RenewableUK with capabilities in the marine energy sector who would like to be listed as a supplier on the gateway should contact
