Tidal Electric is developing a proposal for an offshore tidal lagoon in Scotland. The proprietary technology enabling the lagoon to be placed offshore allows the plant to deliver large scale, carbon free power at unmatched value. Scotland`s tremendous tidal resource and goal of producing as much renewable electricity as it consumes by 2020 make it an ideal partner for an offshore tidal lagoon. Tidal Electric`s offshore impoundments are the next step for hydroelectricity. Cost competitive, commercial-scale renewable energy from the ocean`s tides. Technical discussion of tidal power generation, the business environment, and the identification of potential sites worldwide.
The history of tidal power stretches into antiquity. The earliest evidence of the use of the oceans’ tides for power conversion dates back to about 900 A.D., but it is likely that there were predecessors lost in the anonymity of prehistory. Early tidal power plants utilized naturally-occurring tidal basins by building a barrage (dam) across the opening of the basin and allowing the basin to fill on the rising tide, impounding the water as the tide fell, and then releasing the impounded water through a waterwheel, paddlewheeel or similar energy-conversion device. The power was typically used for grinding grains into flour. Power was available for about two to three hours, usually twice a day.[i] In Hayle, England, tidal power was used to “dredge” a shipping channel by flushing it regularly with a pulse of stored tidally-impounded water.[ii]
