Why ‘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 Coal
”This acquisition continues our strategy of acquiring development and redevelopment opportunities in the north west.”At present, property investments make up approximately 6% of GMPF’s £13bn portfolio, of which two-thirds are in direct holdings and one-third in funds.Morris said that GMPF’s planned target allocation to property in the medium-term is 10%, delivered in various ways.He added direct property holdings were expected to be in the range of 4 to 8% of the total portfolio. But the fund will continue to develop other means of obtaining its property exposure, such as GMPVF. The Greater Manchester Property Venture Fund (GMPVF) has moved to acquire Chorlton Shopping Centre in a £10m (E12m) deal from Development Securities.GMPVF invests in property development and redevelopment opportunities in North-West England on behalf of the Greater Manchester Pension Fund (GMPF)The shopping centre has 16 retail units, a supermarket, offices and a car park. Existing tenants include travel agency Thomas Cook, newsagents Martins, Heron Foods, Quality Save and a large number of independent quality retailers.Peter Morris, director of pensions, GMPF, the largest scheme for local authority workers in England & Wales, said: “This is a long-term investment. We will develop a plan that will see the centre improved over time, respecting the diversity of operators there.
James Southerland was once again in street clothes Monday, sitting out his third consecutive game due to ineligibility. The 6-foot-8 forward, who shoots like a guard in a big man’s body, leaves his team sans a shooter and sans size.It forced the Orange to turn to a three-guard lineup for the first time all season against Cincinnati, employing Triche, Carter-Williams and Trevor Cooney for lengthy stretches of the second half.And though it hurt Syracuse defensively, as Boeheim explained in his postgame press conference, it gave his team a boost on offense. Those three players combined to score 37 points in a 57-55 win against the Bearcats, while also tallying 10 of the team’s 11 assists.“We don’t have a lot of options shooting it,” Boeheim said. “We tried to play the three guards together to get another shooter in the game; it hurts us defensively. But when you’re not scoring you’ve got to try to find a way to score.”The Orange managed only 22 points in the first half Monday and missed seven of its 10 attempts from 3-point range. Southerland, the team’s second-leading scorer and arguably its best outside shooter, would have likely boosted those numbers.AdvertisementThis is placeholder textInstead, that becomes Cooney’s role. The guard finished with eight points, including two 3-pointers. He also chipped in four steals in 18 minutes of play, off-setting the lack of size featured in the three-guard lineup.Cooney said the team began practicing and discussing the possibility of the three-player scenario once Southerland was declared ineligible. It moves Triche, a 6-foot-4 guard, down to one of the wing positions, with Cooney and Carter-Williams out on top of the zone.“It’s something that we’ve talked about and put in the game today, so we’ll see if we put it in again this week,” Cooney said.Judging by Monday’s results, Boeheim may consider using this lineup again if Southerland remains ineligible. The three guards played together from the 16:32 mark of the second half to the 8:54 mark. Syracuse closed Cincinnati’s lead from four to two in that stretch — effective, though not ideal.Up next for Syracuse is Villanova, a team that lacks depth up front. It means the Orange might be able to get away with that lineup one more time before traveling to Pittsburgh in two weeks.Said Cooney: “We’ll make it a lot more difficult for teams to play zone against us if we have that lineup out there.” Comments Related Stories ROARING BACK: Syracuse defies odds again in late comeback win over No. 21 CincinnatiSyracuse overcomes barrage of 3s to fight back against No. 21 CincinnatiCarter-Williams comes up clutch down stretch in Orange’s comeback win against No. 21 Cincinnati Facebook Twitter Google+ Published on January 21, 2013 at 8:48 pm Contact Michael: email@example.com | @Michael_Cohen13
RB Leipzig chief executive Oliver Mintzlaff admits he is “bored” by constant speculation surrounding midfielder Naby Keita.The Guinea international is a target for Liverpool, who are prepared to smash their transfer record to acquire him, after just one season with the Bundesliga club and there are conflicting reports about the player’s future.Although the transfer window has only just officially opened, Mintzlaff has had enough of all the talk, even though he is powerless to prevent it.Asked by Sportbuzzer whether Leipzig were “unresponsive” to offers for Keita, Mintzlaff said: “Yes. And that topic is boring.“This is only our second Bundesliga season, our squad is still the youngest and most likely also the most inexperienced.“Sure, it would be great to start where we left off. It’s an advantage that there’s no upheaval.” Liverpool are prepared to spend big bucks to land Naby Keita this summer 1
