The Blue Energy Power System overcomes the problems of traditional ocean technologies by being both cost effective (US$1200 per kW capacity) and ecologically benign. The “tidal fence” structures are larger arrays of slow moving vertical-axis turbines which allow water and marine life to flow through freely and safely. The system is not dependent upon tidal amplitude, making it viable in many more locations than traditional ocean barrage systems.
