|'Clean coal' stalled |
Until recently, "clean coal" power plants like the 600 megawatt Mesaba Energy Project had seemed like the energy industry's perfect retort to Al Gore: a plant on the Iron Range that could produce reliable power using abundant coal and yet not muck up the environment.
But the controversial project failed to win regulatory approval from the Minnesota Public Utilities Commission this week and similar projects using the same technology elsewhere are collapsing over concerns about <a href=http://www.tiffanyoutlet-2014.com>tiffany</a> cost and feasibility.
Julie Jorgensen doesn't think so. The <a href=http://www.tiffanyoutlet-2014.com>tiffany and co outlet</a> co CEO and founder of Wayzata based Excelsior Energy believes her company's $2.1 billion project will be back and so will its technology, called integrated gas combined cycle, or IGCC for short.
The state's power companies, including Xcel Energy, need fossil fuels to meet growing energy needs, she said, and IGCC scrubs coal of many pollutants like sulfur dioxide and nitrous oxides by a process that turns it into a gas before burning.
The energy industry believes that within a few years, Washington will enact regulations levying heavy penalties on producers of carbon dioxide emissions, which are believed to be accelerating global warming.
That bullet has misfired badly of late, though. Xcel Energy, which opposed the Excelsior project because it didn't want to be forced to buy Mesaba's power, this week shelved an IGCC proposal of its own for the state of Colorado.
Xcel said that after two years of study, it decided its own $1 billion IGCC proposal was too costly to build without a partner.
And last month, Teco Energy Inc. in Tampa, Fla., said it wasn't moving ahead with plans for a $2 billion IGCC unit because of uncertainty over possible emissions regulations and the potential for rising construction costs. IGCC projects <a href=http://www.tiffanyoutlet-2014.com>tiffany outlet</a> that have been canceled or put on hold this year. In September, a Dutch utility tabled a 1,200 megawatt IGCC project in the Netherlands.
Unexpected costs have been dooming many of these projects, said Carol Overland, a Red Wing attorney who is representing landowners on the Iron Range that would have been affected by the Mesaba Power project.
Overland and other critics also contend the plants are not as environmentally friendly as they first sounded. The plants would not reduce emissions of sulfur dioxide or nitrous <a href=http://www.tiffanyblueaustralia.org>tiffany blue</a> oxides significantly lower than that of a brand new coal plant using "pulverized" technology that pounds coal into a dust before burning, she said.
Excelsior officials dispute that assertion, but a two judge panel that studied the proposal for the PUC sided with the critics.
Finally, there's <a href=http://www.tiffanyoutlet-2014.com>tiffany outlet</a> the carbon dioxide. IGCC by itself does nothing to reduce CO2 on its own.
Jorgensen and her husband, Tom Micheletti, Excelsior's other co CEO and founder, maintained that they would build in the ability for their plant to capture and sequester the CO2. They would then ship it via a pipeline into Canada, where it could be sold to oil companies that already <a href=http://www.tiffanyoutletstore1.co.uk>tiffany and co uk</a> are injecting captured CO2 into oil wells to push out the oil while the gas remains trapped underground.
But opponents of Mesaba have pointed out Excelsior's proposal did not include formal plans to spirit away the carbon dioxide. That could tack on another $1 billion to the proposal's price tag, one commissioner suggested.
Next door to Antelope Valley Station is a plant that converts coal into synthetic natural gas, similar to the IGCC process. That plant, a subsidiary business of Basic Electric, ships its leftover CO2 to oil wells in Canada in a 205 mile pipeline.
