The Royal Society has produced a report with a dozen papers on tidal power. Full papers are behind a paywall (of course Sad ) but abstracts are here:

and there's a BBC report here:

Tidal power could indeed generate a significant proportion of our electricity demand.
The output is variable, but unlike with wind power, the output may be calculated far in advance.

The problems are not technical but are planning/NIMBY related.

David MacKay has been touting tidal power for some time and examines it in depth.

In the light of the 15GW potential of the Severn Outer Barrage then I think the NIMBYs can be ignored.

I favour sea bed mounted venturi units.

Given that much of the sea shore along the Severn Estuary is a SAC to try to put a barrage there would entail a visit, probably unsuccessful for the UK, to the European court. The other devices shown above would thus be the best way forward. I think that a number of the Venturi units would be the best option as they look the safest to me. I would have thought that they would also be the most efficient as they concentrate the flow. Probably more expensive though.
