1 New Outline Technical Specification providing Guidance for the Design and Analysis of Ocean Thermal Energy Conversion (OTEC) systems Martin Brown & John Griffiths, IEC PT 20 Committee All Energy Conference, Glasgow, Thursday 7 th May 2015

2 Introduction to IEC The International Electrotechnical Commission (IEC) is a not for profit, nongovernmental organization, founded in The IEC's members are National Committees, and they appoint experts and delegates coming from industry, government bodies, associations and academia to participate in the technical and conformity assessment work of the IEC. 2

3 Using IEC Ocean Energy Technical Specifications The International Committee for Ocean Energy Standards (TC/114) has published the following Technical Specs: IEC Assessment of Performance of Wave Energy Converters IEC Assessment of Performance of Tidal Energy Converters Very shortly the following two will be published: IEC Assessment & Characterisation of Wave Energy Resource IEC Assessment of Tidal Energy Resource We vitally need people to try using these TS's and reporting to our Ad Hoc Groups on their experiences, providing comments. Please contact me on how to do this 3

4 Importance of a Technical Specification for OTEC Reassurance for Investment community review Guidance for technical due diligence 4

5 OTEC (Ocean Thermal Energy Conversion) OTEC a Fairly Well Kept Secret in Europe 5

6 The Oceans as a Gigantic Solar Collector Oceans are a huge solar collector that cover 71% of the globe OTEC provides a means to exploit the solar input they receive 6

7 Ocean Thermocline drives OTEC Thermocline thin layer of warm water overlying a much cooler subsurface water mass 7

8 Land Based (Steep Shore Line) 8

9 Floating OTEC some similarities to a FPSO 9

10 Technical Specification Scope This technical specification establishes general principles and provides useful information to enable design assessment of landbased, shelf mounted, or floating OTEC plants that generate electrical power. This electricity may be used for utility supply, or production of other energy carriers. It is applicable to the OTEC structure, process flows and machinery, and electrical equipment and controls, to the point of interconnection to the primary load or electrical grid. Intended users of this specification are OTEC developers, engineers, regulators and financing authorities. 10

11 Working Group Make Up Martin Brown elected as Working Group Convenor in Dec at a well attended scope review meeting in London 1. Pat Grandelli (Makai, US) 2. Laurie Meyer (La Mer Consulting, US) 3. John Griffiths (JWG Consulting, UK) 4. Yasuyuki (Yasu) Ikegami, (Institute of Ocean Energy, Saga University, Japan) 5. Paul Dinnissen & Remi Blokker (Bluerise, Netherlands) 6. Gouri Shankar Bhuyan, Vancouver, (GB Consultants, Canada) 7. Laura Mae Macadré, (Bureau Veritas, France) 8. Dr. Weimin Liu, First Institute of Oceanography, Qingdao (China) 9. Purnima Jalihad, (NIOT, India) 11

12 Technical Specification Development Very international group so coping with time zone differences means early mornings and late nights for some participants during Skype conference calls Group members have to squeeze in PT20 work between day job 12

13 OTEC Developments Around Globe 100kW prototype Okinawa, Japan DCNS, prototype La Reunion Bluerise, prototype TU Delft 13

14 Key International OTEC Players 14

15 OTEC Developments Around Globe 15

16 New Plant about to go on line in Hawaii August 2015 Official Opening 16

17 Substantial NER 300 Funding Akuo and DCNS offshore NEMO project was awarded 72m Euro in a Second NER300 Call NEMO is an OTEC project off the west coast of Martinique in the Caribbean Sea. A moored barge will be installed housing four turbo generators. Each will be driven by an Ammonia closed Rankine cycle utilising the circa 20 C temperature difference between the cold seawater at 1.1 km depth and the warm surface waters. The cold water is pumped via a single large diameter riser. Each turbine will produce roughly 4 MW resulting in a total nominal installed capacity of 16 MW with a maximum available capacity of 10.7 MW. The net generated power is exported to the grid via a subsea cable and a substation at an existing conventional fossil fuel power plant. 17

18 Conclusions New Technical specification will help to more projects on the go Significant investment in OTEC is happening around the world Oil and gas floating production experience has reduced the technical risk associated with OTEC 18
