Tuesday's development consent for the Swansea Bay tidal lagoon could unleash a number of further tidal lagoon projects, but only if the application for the next one is allowed to proceed before the first one is built.

Getting the first consent was tricky given the lack of precedents, but any pressure to wait until the Swansea project is built to make consenting the next one easier should be resisted as this would introduce an unnecessary delay for such urgently needed infrastructure.
