Integrated Solution

Sustainable Marine Energy (SME) is a turnkey supplier of integrated tidal energy generation systems. SME was founded in 2013 to develop tidal energy platforms and enabling technologies. In 2018 SME merged with the tidal energy business of SCHOTTEL a long standing partner who had supplied tidal turbines to SME and supported platform development from its inception.

SCHOTTEL has transferred all its tidal energy assets, including UK subsidiary TidalStream Ltd and Canadian subsidiary Black Rock Tidal Power Inc., to SME, with Black Rock Tidal Powers’s name being changed to Sustainable Marine Energy (Canada) Ltd. 

SME will be commercializing the tidal turbine technology developed by SCHOTTEL, in conjunction with its platform and anchoring solutions, to offer an integrated solution to the market. SME will also be continuing the development of projects in Nova Scotia, Canada, that will be used to prove up its products, including the 5MW berth at the Fundy Ocean Research Center for Energy (FORCE) that was awarded to SCHOTTEL in 2014. (link to SME)
