Its half-sister at Kincardine came down in the mid-to-late nineties.</p> <p>I doubt it would be deemed echonomical to keep the existing structure if the gas power station goes ahead. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=4098#post-61353 Thu, 15 Mar 2012 15:39:25 +0000 Wilmington's Cow 61353@http://citycyclingedinburgh.info/bbpress/ <p><a href="http://www.scotsman.com/edinburgh-evening-news/edinburgh/cockenzie-power-plant-to-shut-down-1-2175741">Shutting down next year</a> </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=4098#post-42657 Thu, 06 Oct 2011 16:55:07 +0000 kaputnik 42657@http://citycyclingedinburgh.info/bbpress/ <p><em>Does Natural Gas not give off carbon when burned then?</em></p> <p>Per unit of heat generated, brown coal emits 3 times as much CO2 as methane and black coal 2 times as much.</p> <p>Levels of carbon monoxide from gas are about 1/8th for that of coal, NOxes are about 1/2 to a 1/3 of coal and sulphur dioxide is negligible. It also physically generates less flue gas and almost no particulate matter.</p> <p>A modern combined-cycle gas-turbine powered station (buring gas to turn a gas turbine, then capturing the waste heat to generate steam to turn a steam turbine) is also vastly more efficient than a 1960s coal station. You can get 50-60% thermal efficiency in optimal operating conditions for CCGT. Coal is about 30-35%.</p> <p>So it's good all round in those respects. What the gas costs and where it comes from, that's another thing. Bear in mind a lot of the coal for Cockenzie is imported from Russia - getting it here is not a clean and efficient business. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=4098#post-42652 Thu, 06 Oct 2011 16:32:07 +0000 steveo 42652@http://citycyclingedinburgh.info/bbpress/ <p>Not nearly as much, there are also less "other" environmental issues with gas. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=4098#post-42651 Thu, 06 Oct 2011 16:24:45 +0000 DaveC 42651@http://citycyclingedinburgh.info/bbpress/ <p>No the news said it was in line with agreements to reduce carbon, coal being a dirty fuel. Does Natural Gas not give off carbon when burned then?</p> <p>looking at the massive amount of water flowing under the forth bridges as i do most days, they ought to pus some tidal flow energy generation there. If fair hoons through at springs. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=4098#post-42649 Thu, 06 Oct 2011 16:22:41 +0000 steveo 42649@http://citycyclingedinburgh.info/bbpress/ <p>More likely the cost of the new carbon trading scheme means that coal is becoming less and less attractive even as the price of gas rises. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=4098#post-42648 Thu, 06 Oct 2011 16:20:23 +0000 alibali 42648@http://citycyclingedinburgh.info/bbpress/ <p>Probably a decision bolstered by the arrival of fracking, without which the supply of gas would depend on imports. Or maybe in-place gasification of coal that is still in the ground? </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=4098#post-42642 Thu, 06 Oct 2011 15:51:25 +0000 chdot 42642@http://citycyclingedinburgh.info/bbpress/ <p>"they have their own beauty"</p> <p><a href="http://www.youtube.com/watch?v=4JnQ8d8yvZQ" rel="nofollow">http://www.youtube.com/watch?v=4JnQ8d8yvZQ</a></p> <p>.</p> <p><a href="http://www.google.co.uk/search?q=cockenzie+power+station+lit+up#q=cockenzie+power+station+lit+up">More videos</a> </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=4098#post-42639 Thu, 06 Oct 2011 15:45:51 +0000 amir 42639@http://citycyclingedinburgh.info/bbpress/ <p>"Subliminal navigation aid?"</p> <p>More than subliminal.
