Pumped Storage and Tidal Power in Energy Systems

Tidal power has repeatedly been shown to be an unacceptably expensive energy source. The writers foresee a changing position resulting from a substantial increase in nuclear installations coupled with an associated dependence on pumped storage, plus escalating costs together with frequent concern over the supply of fossil fuels. The report shows how tidal power may be harnessed and combined with energy of thermal origin in a two-basin estuary pumped storage project, to give firm output and peaking potential with inherent hydro flexibility. The comparative simplicity of the total system, compactness and freedom from demands on land are distinct features.
