‘Pelamis’ - Wave Energy in Action !!
3
Wave Hub - What is it?
Simple idea! § An area of sea with an electrical cable and connection point
offshore into which arrays of Wave Energy Converters will be connected
§ A connection to the National Grid for initially up to 30 MW
of wave power
§ Permits to allow connection and operation of the facility
4
Why are we doing it?
§ Demonstrate commercial viability of wave energy
5
R&D
Initial prototype
Refined prototype
Pre- commercial device
Market entry with commercial product
Market penetration

Wave Hub … a route to commercialisation
6
What do we hope will happen?
§ Demonstrate commercial viability of wave energy
§ Maintain and strengthen the UK lead in marine renewable energy
§ Develop a new industry in the South West
§ Contribute significantly to the South West renewable energy generation
7
Where did it come from?
§ 2001 SWRDA Regional Renewable Energy Strategy § 2002 Agreement to support biomass, wave and tidal power § 2002 Set up Regen SW § Oct 2003 Seapower South West Report § Jan 2004 METOC Seapower SW Review § April 2004 Wave Hub Feasibility Study Starts

Project Requirements (What do we need to do?)
§ A site (offshore and onshore) § A suitable resource (wave energy) § A grid connection § Feasible technology (practical and cost effective) § A business case (market need and financially viable) § Legally allowed to do it (permits and consents including an
EIA) § Stakeholder support

Potential Benefits
The potential to create an International industry in SW
§ Development of wave energy sector and associated supply chains – including marine technology and advanced engineering resulting in over 450 jobs in the
SW by 2010 and 700 by 2020. § Inward Investment
– GVA from indirect impacts to the SW of £15million and £27 million respectively with 20-40% expected in Cornwall.
§ 20MW wave power produced and sold by 2008 – supplying 14,000 homes; meet up to 30% of Cornwall’s renewable energy target and
up to 5% of the Regional target. § Links to Higher Education
– Centres of Excellence in CUC, Plymouth and Exeter leading to the establishment of a high profile wave energy R&D base in west Cornwall.

Conclusions
§ It is Technically Feasible !! § It is wanted and supported by Industry and Government § It is supported by SWRDA § It appears to have positive environmental benefits and
negligible negative impacts (to be confirmed by EIA) § It has Local Stakeholder support (so far) § It is legal § It requires a lot more work! § It will cost - but not excessively so! § We are not alone!
