Why ‘Clean Coal’ Remains out of Reach

first_imgWhy ‘Clean Coal’ Remains out of Reach FacebookTwitterLinkedInEmailPrint分享Robert Rapier for Forbes:Since the coal industry and utilities that use coal want to continue to exist, they have pushed the clean coal narrative for many years. After all, if there is some hope that this dream is achieved, perhaps the EPA could cut them some slack while they work out the kinks.It’s not so hard to imagine how it would be done. In fact, it’s already been demonstrated many times at a pilot scale. The exhaust from the power plant stack is captured, compressed, and stored underground — either in a cavern or an old oil or gas field.The key challenge has always been one of economics. The capital cost of capturing and compressing those emissions is very high, and the power consumed in compressing the carbon dioxide places a parasitic load on the power plant. Just to compress the emissions can require the electric power requirements of 10% of the plant output, and then it must still be transported to an appropriate site and pumped into the ground. All of these factors drive up the costs to the point that coal power with carbon capture is prohibitively expensive relative to competing ways of producing power.The prohibitive costs are amply demonstrated by the FutureGen project in Illinois. This project was a partnership between the United States Department of Energy (DOE) and an alliance of coal mining and electric utility companies. The project was to be located at the 275 MW Meredosia Power Station in Illinois.FutureGen won $1.1 billion in federal money in 2009, and the project cost was estimated to be $1.65 billion. The DOE spent $202 million on the project, but missed project deadlines and unresolved technology challenges ultimately caused the DOE to pull the plug on the project in 2015.While there are a number of other pilot projects underway around the world, they all suffer from the same basic problem. The costs of competing technologies are close enough to coal that when you try to capture the carbon dioxide emissions it pushes the cost of coal-fired power beyond the competition.Thus, in reality there aren’t any commercial clean coal technologies. It’s very likely there won’t be any. So for countries that have committed to reducing carbon emissions, the pressure to phase out coal will continue to be intense.Full item: The Elusive Search For Clean Coallast_img read more

Five Premier League thrillers that live long in the memory

first_imgAdam Lallana’s stoppage-time goal earned Liverpool a 5-4 win at Norwich – the final dramatic act of a thrilling afternoon at Carrow Road. Manchester City 3 QPR 2, May 2012 Perhaps the most significant of all, City started this game knowing a win would earn them a first Premier League title but when they went 2-1 down – even against ten men – it looked as though rivals United would take the trophy. However, Edin Dzeko scored with two minutes of time added on to level and then, memorably, Sergio Aguero (or to quote Martin Tyler, ‘Agueroooooooooo’) won both the match and the title with 93:20 on the clock. Liverpool 4 Newcastle 3, April 1996 Sure to feature on everyone’s classic list, this was the game which saw Newcastle boss Kevin Keegan slump over the front of the dugout as his side’s title chances went up in smoke. Liverpool came from 2-0 down, only to see Faustino Asprilla make it 3-2 seconds later. Stan Collymore soon levelled and then won it two minutes into added time, with Tyler again taking over with his line of “Collymore closing in”. Newcastle 4 Arsenal 4, February 2011 When Theo Walcott scored for Arsenal 44 seconds into this game it set the tone for a blistering period of away play, with Johan Djourou and Robin van Persie (two) putting Arsenal 4-0 up. Reds boss Jurgen Klopp lost his glasses amid wild celebrations on the touchline, the German getting a real taste of the kind of finishes the Premier League can conjure up. Here, Press Association Sport looks at five other late-goal classics. Press Association However, the game turned as Abou Diaby saw red for Arsenal and Newcastle mounted a stellar comeback. Two penalties from Joey Barton and a Leon Best goal gave them a foothold, but they still needed a brilliant 87th-minute volley from Cheik Tiote to get a point. Leicester 3 Arsenal 3, August 1997 Perhaps best remembered for Dennis Bergkamp’s brilliant solo goal, this game had far more to it. The Dutchman’s wonder goal was actually to put Arsenal up after Matt Elliott had scored in the third minute of stoppage time for Leicester to make it 2-2, but there was still time for Steve Walsh to score another dramatic goal and make it 3-3. Chelsea 2 Arsenal 3, October 1999 Arsenal, again! Nigerian Kanu took centre stage as the Gunners mounted a terrific comeback against Chelsea at the Bridge. Headers from Tore Andre Flo and Dan Petrescu got Chelsea 2-0 up, but then Kanu took control. He pulled two back from close range in regulation time and then, in stoppage time, broke free, skipped past keeper Ed de Goey by the corner flag and then curled in the winner from an improbable angle. last_img read more
