1 Making tidal power a reality Nautricity s Tidal Technology Development Program Cameron M. Johnstone CEO

2 Nautricity Limited Nautricity: a Scottish tidal technology company aiming to make tidal energy cost and reliability competitive with offshore wind, and thereby develop a global scale industry. Company history University of Strathclyde Spin-out Company formed in obtained exclusive global license to the University it of Strathclyde sth CoRMaT turbine technology and recruited inventor, Cameron Johnstone. The company also completed its first venture funding bringing in First Tech as a shareholder and raising sufficient funds to commercialize the CoRMaT device. By 2011 Nautricity completed FEED studies on CoRMaT technology at 50, 250 and 500KW scales and formed first two Single Purpose Vehicles to develop commercial sites.

3 First Generation Tidal Devices marinised wind These devices are all big, heavy, and require extensive seabed engineering in hostile environments their ultimate cost is driven by the mass of materials used.

5 Technology: Next Generation Tidal Turbine The novel idea behind the contra-rotating tti turbine concept is to use two closely spaced dissimilar rotors, moving in opposite directions for deployment in lower velocity sites. This has several technical and cost advantages over single rotor designs: Increases the efficiency of energy capture Eliminates complex blade pitch control Reduces turbulent flow downstream Minimises reactive torque, thus promising a lower cost, flexible mooring possibility Increases dynamic stability Increases relative shaft output speed Electrical power take off possible via direct drive of a contra- Electrical power take off possible via direct drive of a contrarotating generator.

7 Disciplined, comprehensive development Stage 5 TRL 8 Extended commercial demonstration at sea Stage 4 TRL s 5 Scale prototype generated electricity in tidal stream off Islay 2006 Stage 3 TRL s 4 Small scale model deployed in Kyles of Bute proves dynamic stability and ease of deployment and recovery Stage 2 TRL 3 Tank testing proves energy capture and torque load cancelation Stage 1 TRL s 1-2 First principles analysis of tidal generation challenge leads to contra-rotating turbine concept

8 Contra-rotation t ti drives competitive advantage Contra rotating generator No gearbox No foundations Reduced wash Low blade speed / high solidity no variable pitch Free to orientate to current High energy capture Simple, light device only 3 sub assemblies Reduced chance of failure Rapid deployment / recovery Small support vessel Small inter-device spacing No marine life damage Low operating cost /MWh Low capital cost /MW Low environ- mental impact

9 Mooring system with Hydro-buoy Technology EMEC testing Combines displacement buoyancy with hydrodynamic lift, varying mooring tension proportionally with tidal velocity. Reduces amount of subsurface buoyancy required to create required tension Maximises mooring tension, reducing mooring footprint Patent filed in UK in 2011 Pat. App. No PCT process underway.

10 Phase 1: HydroBuoy and CoRMaT Full Scale Testing at EMEC, Orkneys, 2013 EMEC Deployment Feb 13 EMEC Deployment, Feb 13 - Hydro-buoy performance analysis

11 Full Scale CoRMaT Manufacture GFRP Blades Contra-rotating radial PMG

12 Assembly and pre-testing at Montrose staging post Preparing for EMEC Deployment

13 Phase 2: Deploying at EMEC, 2014 Installing the CoRMaT 500 using a 100% local supply chain Securing to the Installation Vessel

14 Day of installation: Tow out timed to be at site 1.5hrs before slack water, end of ebb. 04:00 hrs Tow Out

15 Securing Position above the pre-installed mooring

16 Sinking, Connection and Hook-up in less than 20 mins. Going, Going, Gone!!!

17 Recovery and Decommissioning - Turbine recovered and secured on tow vessel within 50 minutes - Site completely decommissioned within the day.
