Marine renewables: a new innovation frontier.

The UK has a large marine renewable energy resource and has been developing a range of wave and tidal technologies for exploiting it. However, progress on moving to the commercial scale has been slow, in part, it is argued, as a result of the way this area of innovation has been supported by the government. This paper looks at the technologies and how they are being developed in the UK and elsewhere. It notes that, although the UK is still in the lead in terms of novel device development, unless better support is provided, the UK might lose out to device developers from other countries in the race to capture the very large global market that is opening up for the relevant technologies.
