A tidal lagoon is a form of tidal power generation built as an independent enclosing barrage on high level tidal estuary land, distinct from a conventional tidal barrage because it does not block the flow of the river or estuary it sits on. A single lagoon pool can generate around 3.3 watts per square meter, a dual lagoon arrangement can provide continuous output at around 4.5 watts per square meter, and an enhanced configuration that adds pumped storage can reach around 7.5 watts per square meter. As one of several generating methods grouped under tidal power, the tidal lagoon remains a proposed rather than a widely built technology, distinguished from a barrage mainly by its self contained structure and its lighter impact on the estuary around it.
Facts
Technology TypeA self-contained tidal power barrage built as an artificial pool along a coastline, generating electricity from the rise and fall of the tide without blocking a river or estuary. 1 Invented YearMarks UK development consent for Tidal Lagoon Swansea Bay, billed as the worlds first tidal lagoon power plant; the project was later refused funding by the UK government in 2018 and no tidal lagoon has yet been built.
