Title:
TIDAL POWER GENERATION AND STORAGE
Document Type and Number:
WIPO Patent Application WO/2014/140629
Kind Code:
A3
Abstract:
A tidal power generation and storage system (10) comprising three tanks (12, 14, 16) located in a tidal sea (18). Two of the tanks (12, 14) are in fluid communication with the sea (18) such that a first one of them (12) can be filled to sea level (20) at high tide, whereas the second tank (16) can be emptied to sea level (20) at low tide. A first fluid passageway (26) extends the first pair of tanks (12, 14), which passageway (26) comprises a first turbine-generator assembly (30) that generates a first power (48), which is used to drive a pump (32) for pumping water between a second pair (12, 16) of the three tanks via a second fluid passageway (34). A third fluid passageway (40), extending between a third pair of tanks (16, 14) is also provided, which passageway (40) comprises a flow control means and a second turbine-generator assembly (42,44) configured to generate a second output power (49) as water flows between the third pair of tanks (16, 14).
