2 Aims of the review SNAPSHOT OF KEY CHALLENGES AND OPPORTUNITIES ASSESS AUSTRALIA’S CONTRIBUTION TO POOL OF GLOBAL KNOWLEDGE HOW ARENA/AUSTRALIAN GOVERNMENT CAN BEST SUPPORT THE MARINE ENERGY SECTOR

4 Initial findings from ARENA’s review TECHNOLOGY o Some Australian companies at cutting edge of marine R&D o Designs yet to converge, reducing economies of scale DATA o Paucity of data in real operating conditions OPPORTUNITIES o Significant global investment planned in R&D o Largest wave/tidal market projected to be in Europe/Canada, some opportunities in Asian/South American markets ARENA’S CONTRIBUTION o Data on economic case, environmental impact and grid integration o Monitor progress of ARENA projects, encouraging dissemination of energy output and environmental impact data, re-evaluate following project completion Biopower’s O Drive

5 Wave, tidal, other ocean were considered for this review Oscillating Wave Surge Converter Oscillating Water Column Point Absorber Use surge motion of waves to produce horizontal oscillating motions Chamber part filled with water to drive air through a turbine Buoy connected to fixed mooring heaves with waves Attenuator use oncoming waves to induce an oscillatory motion between two (or more) adjacent components Terminator converts wave energy into potential energy by collecting water in reservoir and releasing it to flow through hydraulic turbine 5 main types of wave devices demonstrated Power can be generated either at sea or water pumped to onshore turbine Tidal current devices sit in water in arrays like wave devices, wind turbines Tidal barrages are dams which control the flow of water across tidal waterways to generate power Other ocean technologies including thermal current and salinity gradient at very early stage Offshore wind not considered ARENA supported Sources: SI Ocean, State of the Art (2014) ; UK Carbon Trust, Accelerating Marine Energy (2011) Horizontal axis device common (see left) Similar to underwater wind turbine Little convergence in design of foundation and support structures.

8 Deployment key to reduce costs for wave, tidal Wave Tidal UK LCOE expected to be around $A225/MWh for wave/tidal current if 2GW installed globally (green line) UK government has indicated it will enter into wave/tidal current contracts for difference up to a total value of £305 (A$513) UK contract for difference scheme uncertainty affecting market investment According to above, only the most competitive wave would be supported, but tidal current more viable Blue line indicates projected build by 2020 with current funding (assuming split 50:50 between wave and tidal current – approx 25MW of each) Note – LCOE in Euro cents Sources: Renewable UK, Wave and Tidal Energy in the UK Conquering Challenges, Generating Growth (Feb 2013) ; UK Carbon Trust, Accelerating Marine Energy (2011) UK strike price for marine

9 Australia’s marine sector and market outlook CURRENT LCOE APPROACHING REMOTE DIESEL COST o niches such as off-grid, coastal infrastructure protection o Australian companies targeting cost competitiveness with diesel by 2020 and ultimately on-grid power o European companies are not generally considering niche opportunities SYNERGIES MAY FURTHER REDUCE COST o cooperation between companies o capitalise on wave, tidal and offshore wind deployment globally o alignment with offshore gas, automotive, shipbuilding manufacturing skills POSSIBLE DEPLOYMENT OF INTERNATIONAL DEVICES o tropical tidal testing if European companies wish to explore Asian/South American/African markets o wave/tidal testing if Southern hemisphere lessons transferrable (i.e. to South Africa, Chile etc) COMMERCIAL ON-GRID POWER POSSIBLE IN AUSTRALIA o Depending on pace of deployment overseas, cost reductions expected to occur – timing to commerciality - tbd Sources: Conversations with Oliver Wragg (EMEC), Shawn and Glen Ryan (Bombora), Dr Peter Osman (CSIRO)

12 Data from ARENA projects will add to pool of global knowledge ECONOMIC CASE o where the best sites are for marine energy investments o understanding of performance and project cost o skills and infrastructure needed to support wave energy projects ENVIRONMENTAL IMPACT o impact of wave arrays on marine environments o managing risk issues INTEGRATING WAVE POWER INTO THE GRID o better understanding of how marine energy fits with demand Cable laying at test site: Source, European Marine Energy Centre
