Harvesting hydrokinetic energy is an attractive addition to the renewable energy mix. And it has one important advantage: you can count on it. You don’t have to wait for wind or sun. Hydrokinetic energy is predictable. It is there, whenever you need it.

SCHOTTEL HYDRO is specialized in developing instream turbines. Our solutions make instream energy highly attractive for grid management – even for isolated applications. They are characterized by

  • Low capital expenses per installed power
  • Low maintenance costs 
  • Easy access
  • High availability
  • High efficiency
  • Optimum grid connection
  • Extreme robustness

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.

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.
