Johnny Porritt rides again!

So they\’re not going to fund the Severn Barrage. Sir Jonathan says:

Jonathon Porritt oversaw a 2007 report that backed the giant barrage while he was chair of the government advisory body, the Sustainable Development Commission, which was itself abolished last week. Last night he said: \”If the government is not prepared to find any mechanism to put public funds into the pot, it will die..

\”It\’s a good way to generate a lot of clean energy,\” he said. \”If it is a choice between a [large] barrage on the Severn and two nuclear power stations, then it is clear to me which is better – it is the barrage.\”

Actually, no, it\’s not a very good way at all. As some pendant wrote over at The Guardian some time ago.

It\’s one of these projects that the bigger we build it the more money we lose.

And that\’s true not even in comparison to nuclear, but in comparison to gas fired plant. Yes, even including the fines from the EU and the CO2 emissions, the Severn Barrage still loses money even if we have to get our electricity by burning whatever Putin is willing to sell us.

Bad luck Johnny, must be a right pisser watching the destruction of the idiocies that you so carefully constructed.

  1. Poor old Johnny, it hasn’t been a good year for him has it. First off his Sustainable Development Commission proved to be anything but, and now his beloved barrage has been canceled. In the centuries to come millions of people will be able to enjoy the natural beauty of the Severn estuary; this idiot would have destroyed it for nothing.

  2. …and what of the proof it will not screw up the Severn ecosystem?

    I bet if a nasty corporation tried to do it without green blessings, the environmentalists would be all over the greedy private company like a rash.

    Why is it they want to put wave power in probably the most risky place in the UK, when I am sure there are plenty of barren rocks being pounded by the sea, or cliffs facing erosion where it might be better placed. No, shove it in front of a massive tidal silt and mud bird paradise. Go on.

  3. I have another problem with the Severn Barrage, te same one I have with wind power – there’s no guarantee that the turbines will be turning when the power is actually needed.

    For any hydro power scheme to work you need a high difference in water levels between one side of the turbine and the other. In a tidal system this is provided by the high and low tides. But high and low tides don’t happen at the same time every day. Indeed the tides work on a two week cycle. If morning high tide is at 08H00 today, the next time you will get a morning high tide at 08H00 is in two weeks time.

    Now tidal systems do work in both directions so this problem is reduced to a one week period. Even so, our peak generating times are not necessarily going to mesh with peak demand times.

    You also have to accept that in each tidal cycle there will be slack tijmes when the difference in water level between the high side and the low one is insufficient to produce enough flow to generate anything.

  4. This can be solved by using a combination of turbines which work on the tidal currents and lagoons which operate like normal hydro on the tidal ranges. The turbines have maximum power around the half way point in the tide where the lagoons have nothing. The lagoons max out at high and low water where the turbines have nothing. Combine the two and you have extremely predictable power at all points of the tide.
