Abstract
Further to the evaluation of the development of ocean energy technologies, as reported in the IEA-OES 2006 report, Review and Analysis of Ocean Energy Systems, Development and Supporting Policies, [1], additional evaluation of the technologies and their development status was carried out during 2007 and 2008. Ocean energy conversion systems are being developed in a number of countries, as shown in Fig. 1, with the United Kingdom leading the development effort, followed by the United States. Canada and Norway also have a significant number of technology development activities. In addition to these statistics, numerous research and development initiatives are currently being pursued in various academic institutions throughout the world. Also, renewed activities toward developing small to large-scale marine energy projects can be observed within the global marine energy domain [2].
