The All Energy conference and exhibition in Aberdeen, Scotland saw growing evidence of the wave and tidal sector's push toward commercialisation. Over 210 of the 580 exhibitors were involved in marine energy, the organizers said, and 15 hours of the conference were devoted to the sector. And, for the first time at this long-running show, an innovation technology showcase featured wave and tidal device developers from the UK, Norway, Australia, Canada and Russia.
