UK ethical investment company Abundance has closed a £7m ($8.96m) crowd-funding drive for Orbital Marine Power, its largest to date, to move the Scottish tidal energy company’s 2MW turbine into commercial production.

The first of the company’s ocean-riding O2 design - which measures 73-metre-long and features a pair of hinged 16-metre-diameter turbines that can be raised or lowered to simplify transport, installation and maintenance - is expected to be built "in the next 12 months”, for deployment at the European Marine Energy Centre (EMEC) in Orkney during 2020.
