The international DMEC Accelerator consists of eight innovation projects, covering the entire trajectory from concept to commercial deployment of marine energy solutions. In these projects, DMEC leads several groups of research institutes, technology developers and industry partners in the support of many technologies. Developers receive technology- and business support, are granted access to test facilities, are supported to apply standards and certification and enabled to get in touch with investors, policy makers and end users. We bring the potential of all these projects together by stimulating a collaborative approach to accelerate marine energy development.
