2 INTRODUCTION SCHOTTEL GROUP SCHOTTEL is an innovative group of companies specializing in the development, design, production and servicing of azimuthing propulsion and manoeuvring systems, controllable pitch propellers as well as complete propulsion systems with power ratings of up to 30 MW for vessels of different sizes and types. Based on more than 60 years of experience in submerged rotating power systems in harsh marine environment, SCHOTTEL now took a step into tidal energy. WE KNOW WHAT MOVES SHIPS YOUR PROPULSION EXPERTS 2

5 INTRODUCTION SCHOTTEL HYDRO MISSION STATEMENT & THREE COLUMNS SCHOTTEL HYDRO aims to reach leadership of the emerging hydrokinetic energy market. Component Supply High quality systems engineering and manufacturing on demand SIT Systems Modular toolkit, adaptable and reliable at lowest cost of energy TidalStream TRITON Semi-submerged floating platforms for cost-effective large-scale applications 5

6 INTRODUCTION HYDROKINETIC ENERGY (ENERGY FROM TIDAL AND RIVER CURRENTS) Hydrokinetic energy is a renewable energy source is practically inexhaustible is more reliable than wind, solar and wave energy features higher energy density than wind has much less environmental impact than hydro dams or tidal barrages inheres a predictability that is highly attractive for grid management 6

7 TIDAL ENERGY POTENTIAL WORLDWIDE Source: tidal-resources.jpg 7

8 TIDAL INDUSTRY MARKET DRIVERS Demand for (renewable) energy Community scale / remote locations Utility scale / national energy policy Reduction of emissions Grid management / base-load Feed-in tariffs, subsidies & public grants Private equity, commercial loans bankability Examples for estimated market volume: 2.0 GW UK, 300 MW Bay of Fundy* Obviously much less market volume than e.g. solar and wind, but still significant * European Ocean Energy Association 2010 / Marine Renewables Canada

9 TIDAL ENERGY TECHNICAL & ECONOMIC CHALLENGES Harsh environment: High currents, wave regime, salt water Grid connections Environmental and navigational conflicts Installation and maintenance vessels Technology developers lack experience in marine engineering, production & global O&M facilities (unlike SCHOTTEL) Levelised cost of energy (LCoE) needs to be competitive: CAPEX incl. installation / foundation / cabling OPEX / maintenance costs maximised energy yield / revenue

10 TIDAL INDUSTRY COMMON APPROACHES Surface piercing (e.g. MCT) Expensive installation Limited to shallow water In situ access Seabed-mounted (e.g. Andritz Hammerfest, OpenHydro) Expensive installation Unsuitable for deep water Back-to-base maintenance Floating (e.g. Bluewater) Liable to storm damage Sheltered sites only However, cost-effective CURRENTLY VERY HIGH COSTS NOT BELOW 7 M /MW (rather M /MW) 10

11 SCHOTTEL HYDRO COMPONENT SUPPLY 11

16 SCHOTTEL INSTREAM TURBINE - SIT DESIGN PHILOSOPHY Turn the cube/square law into benefit Downsize turbines to 50 kw Turbine weight 1 50 kw 20 x 50 kw = 1 20 tonnes! Apply the KISS principle Simple and robust drive train Fixed pitch, variable speed Cooled by ambient water Be adaptive to a wide range of sites Scalable in terms of quantity 3 speed classes (D rotor = 3.0 / 4.0 / 5.0 m) Platform agnostic ( horses for courses ) 16

17 SCHOTTEL INSTREAM TURBINE - SIT DEVELOPMENT AND FULL-SCALE TESTING DRIVE TRAIN BACK TO BACK Drive train, control system, long-term behaviour ROTOR + DRIVE TRAIN; TUGBOAT Rotor characteristics, efficiency, loads, overspeed conditions, cavitation 17

18 SCHOTTEL INSTREAM TURBINE - SIT TURBINE TESTING STRANGFORD LOUGH WEEKS TURBINE TESTING In cooperation with Queens University Belfast and IWES Fraunhofer According to International Electrotechnical Commission (IEC) Standards Environmental impact study Funded by EC s FP7 program MARINET 18

19 SIT APPLICATIONS SME S FULLY SUBMERGED PLATFORM PLAT-O Phase 1: Recently successful power tests off Isle of Wight, UK Not grid-connected Phase 2: Commercial deployment at EMEC soon Grid-connected Scope of supply: 2 x SCHOTTEL Turbines (D=4.0m) Turbine control system 19

20 SIT APPLICATIONS SME S FULLY SUBMERGED PLATFORM PLAT-O Phase 1: Recently successful power tests off Isle of Wight, UK Not grid-connected Phase 2: Commercial deployment at EMEC soon Grid-connected Scope of supply: 2 x SCHOTTEL Turbines (D=4.0m) Turbine control system 20

21 SIT APPLICATIONS SME S FULLY SUBMERGED PLATFORM PLAT-O SCHOTTEL AND SME WILL COORPORATE ON FURTHER PROJECTS SME purchased two SCHOTTEL Turbines which recently produced first power on a PLAT-O platform SCHOTTEL has supported SME technically to get to this stage SCHOTTEL and SME are drawing up a joint plan for product development 21

22 SIT APPLICATIONS BLUEWATER COMMUNITY-SCALE SHOWCASE SCHOTTEL HYDRO is member of Texel demonstrator consortium (incl. Bluewater, Damen, van Oord and others) Two SIT turbines to be deployed at Texel in early 2016 Bluewater and SCHOTTEL HYDRO intend to offer community-scale solution 22

23 MAKING TIDAL ENERGY COMMERCIALLY VIABLE TRITON PLATFORM Semi-submersible platform for mounting multiple tidal turbines Following the tide passively Operating position: Maintenance position: 23

24 TRITON PLATFORM INCREASE REVENUE: POSITIONED FOR OPTIMUM RESOURCE UTILISATION Find the best position for the turbines in the water column Maximise energy capture Flow velocity (approx 1/7 th rule) Advantages over common approaches: Surface floaters are in wave / storm affected zone 75% of energy is in the upper 50% of depth Triton operating zone 25% of energy is in the lower 50% Bottom-mounted turbines are in sediment / debris transport region and in poor flow 24

30 CONCLUSIONS - Tidal energy can be an attractive contribution to the energy mix - Global markets, both in community scale and utility scale - The emerging industry has to overcome technical and economic challenges - First arrays will be in the water soon - Demonstrator projects can already be commercial, based on feed-in tariffs or high spot-market prices - Tidal energy arrays can be commercial at lower LCoE by scaling up
