3.4 / INTERNATIONAL VISION FOR OCEAN ENERGY<br />
Leaders of the Activity<br />
Dr. John Huckerby (Chairman of <strong>OES</strong>) and Mr. Henry Jeffrey (UK Alternate) with help from Ms. Laura Finlay<br />
and Mr. Jonathan Sedgwick (Edinburgh University).<br />
Duration<br />
This Activity was commissioned in April 2011 to follow on from the first phase, which led to the publication<br />
of “International Vision for <strong>Ocean</strong> <strong>Energy</strong>” brochure in October 2011. The second phase work began in<br />
earnest in November 2011 and was completed in October <strong>2012</strong>.<br />
Objectives<br />
The objectives of this Activity was to update the statistical information cited in the first version of the<br />
brochure by collaborating with the IEA’s modelling group, who had begun modelling for the biennial<br />
<strong>Energy</strong> Technology Perspectives <strong>2012</strong> publication. For the first time, an IEA publication would include<br />
marine energy in its full modelling runs. The revision to the International Vision brochure would thus include<br />
peer-reviewed and modelled information from <strong>OES</strong> and the IEA, helping to fulfil <strong>OES</strong>’s stated mission to<br />
become the “Authoritative International Voice for <strong>Ocean</strong> <strong>Energy</strong>”.<br />
Achievements in <strong>2012</strong><br />
The modelling work with the IEA began in November 2011 with a meeting between the IEA modelling<br />
group and the <strong>OES</strong> Chairman. The International Vision team then sought information on capex and opex<br />
costs, learning rates and qualitative resource estimates (by geographic region) for the following forms of<br />
ocean energy - wave, tidal current, tidal rise and fall, ocean thermal energy conversion (OTEC) and salinity<br />
gradients. Ranges of levelised costs for the first three forms of ocean energy were found relatively easily but<br />
costs for OTEC and salinity gradients were much more difficult. This was because OTEC developers were<br />
sensitive about releasing commercial cost forecasts and different salinity gradient technologies are still at<br />
an experimental stage. In the end the International Vision team could only submit information on wave,<br />
tidal current and tidal rise and fall to the modelling.
