Tidal Developers
The following table contains a list of the tidal energy concepts known to EMEC. This list is alphabetical by company name and is not intended to infer any endorsement by EMEC of the concept or the companies concerned. The immature nature of the industry means that some of the categorisation of devices may not perfectly fit the simplified assessment made for this web site. If you have any additions or amendments, please contact us.
