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

Federer wins record eighth Wimbledon title

first_imgLONDON (Reuters) – Behind Roger Federer’s artistry and charm lies a ruthless streak of razor-edged steel which surfaced again on Sunday as he thrashed suffering Marin Cilic 6-3 6-1 6-4 to secure a record eighth men’s Wimbledon singles title.The incomparable Swiss turned his 11th Wimbledon final into a procession as tearful seventh seed Cilic, battling his nerves and a bloody blister, suffered a torrid afternoon.Federer described Cilic’s predicament as “cruel” after ending his torment with an ace after one hour 41 minutes — but there was no hint of sympathy as, 23 days before his 36th birthday, he became the oldest Wimbledon men’s singles champion.That attitude from the third seed, who last triumphed at the All England Club five years ago, was not surprising since Federer’s dream of title number eight had been shattered by Novak Djokovic in the 2014 and 2015 finals.His take on Cilic’s injury spoke volumes for the killer instinct that has earned him a record-extending 19 majors and taken him past American Pete Sampras’s record of seven men’s singles titles at Wimbledon in the modern era.“I couldn’t tell what it was,” Federer said. “But if I saw him limping around, or if I saw him pull up hurt, I would start to think, maybe I’ll throw in a dropshot to really check him out, then one more, because that’s what you do.“You need to hurt him where it hurts already.”It was not really necessary as Federer enjoyed one of his easiest title victories.Having reached the final without dropping a set, he was braced for Cilic’s power tools but, apart from the first four games, resistance from the Croat was about as daunting as a man brandishing a stick of celery.In winning the tournament without the loss of a set, Federer matched the 1976 feat of Swede Bjorn Borg and his own run 10 years ago at the Australian Open.Latest MilestoneHis latest milestone continued a remarkable resurgence for Federer, who took six months off last year before returning to win the Australian Open — ending a five-year wait for an 18th grand slam many thought would remain elusive.“I’ve got to take more time off, I don’t know!” said Federer, whose family has doubled with the addition of twins Leo and Lennart to go with twin girls Myla Rose and Charlene Riva since his 2012 title — all of whom were watching on Sunday.“It is very special. Wimbledon was always my favourite tournament, will always be my favourite tournament. My heroes walked the grounds here.”For Cilic, who beat Federer in the U.S. Open semi-finals before going on to claim his sole major in 2014, his first final at the citadel of tennis, was a living nightmare.In pain from a blister, his legs appearing tied together and his mind in turmoil, Cilic seemed on the verge of quitting as the tears flowed and the crowd murmured in embarrassment.“I got a really bad blister,” Cilic said, explaining his mid-match meltdown that had fans nonplussed. “It didn’t hurt so much that it was putting me in tears. It was just that feeling that I wasn’t able to give the best.”Shaky StartNerves were apparent for both men as Cilic opened the 131st men’s final with a shaky service game.Federer, who lost serve only four times in the fortnight, saved a break point at 1-2 and in the next game.At 2-2 Cilic took a tumble to the turf trying to reach a Federer dropshot and followed that with two lame backhands to hand master front-runner Federer control.Scenting blood, Federer polished off the first set before breaking Cilic to lead 3-0 in the second.Cilic slumped to his chair, sobbing, as the physio and doctor stood by and for a moment it looked as though the final might end in a retirement for the first time since 1911.Cheered on by the crowd, Cilic returned to the fray but any sense of a real match had vanished as Federer raced through the rest of the second set.After treatment on his stinging feet, Cilic at least showed some spirit to detain Federer for 40 minutes in the third set.But the outcome was never in doubt as the Swiss, eyes narrowing for another batch of records, broke in the seventh game before wrapping up the match with his eighth ace.last_img read more
