This paper summarises UKERC roadmapping activity in the last 12 to 18 months. A summary of previous activity is provided since the start in April 2005, to put the current status in context. Results of questionnaires and discussion summaries are presented in the paper, which shows that UKERC has adopted a consultative and consensus based approach to developing a technology road-map. As well as reinforcing the approach being adopted, constructive criticism was provided in the discussions at the Oxford workshop to assist in the development of the road-map. All the data collected since the start of the road-map is being collated and analysed to develop one road-map for the international marine renewable community. This paper provides a sample of some of that data.
