Abstract
Ocean Energy Systems (OES) is the short name for the Technology Collaboration Programme on Ocean Energy Systems under the International Energy Agency (IEA). This Annual Report presents an overview of the activities undertaken within OES in 2017, as well as updated country reviews prepared by the Delegates.
The Strategic Plan for this next five years continues to be the guiding document for the OES work programme. The development of ocean energy has been slower than expected. A longerterm vision is required to see the development of ocean energy to the stage where it becomes a viable, cost-effective and reliable alternative to other forms of renewable energy. The added value of the OES arises from good, truly international cooperation. OES is the only intergovernmental, multinational organization in the ocean energy sector, independent of any commercial interests and composed of active members, that encompass the full range of interests from government policy to industry developments. For this new work period, OES will bring added value to national activities by coordinated efforts on priority topics for the whole sector and by delivering clear key technology policy messages to decision makers.
