:: Limpet (Land Installed Marine Powered
Energy Transformer) is a shoreline energy converter sited on the
island of Islay, off Scotland’s west coast.
Limpet device – Limpet 500 – was installed in 2000 and produces
power for the national grid.
Limpet uses the principle of an
oscillating water column. The following diagrams show how this
Limpet is a shoreline unit and ideally placed to
generate electricity in areas exposed to strong wave
We are currently developing the technology used in
Limpet to build a series of commercial power generators. We are also
investing in further uses, including housing a series of units in
We also use Limpet a developmental facility, to
demonstrate new systems and improve its output. A current project
includes installing a new variable pitch turbine, which will
increase Limpet’s power performance.
