Indeed, the effort to paint coal as environmentally friendly is not an easy endeavor, especially when the climate movement has picked up speed and lambasted the industry for contributing more than its fair share to the global warming dilemma.
Activists around the world have targeted coal for a number of reasons. First, coal is still plentiful (compared to gas and oil) so stopping its use will largely curtail carbon output down the road. Second, it is the dirtiest of all fossil fuels. Lastly, in the US the fleet of coal-fired power plants is almost old enough to file for Medicare, so these aging plants are sitting ducks for closure efforts.
"NASA climate scientist James Hansen ... has demonstrated two things in recent papers," writes environmental author and activist Bill McKibben about the need to axe coal. "One, that any concentration of carbon dioxide greater than 350 parts per million in the atmosphere is not compatible with the 'planet on which civilization developed and to which life on earth is adapted.' And two, that the world as a whole must stop burning coal by 2030 - and the developed world well before that - if we are to have any hope of ever getting the planet back down below that 350 number."
If this were a prize fight, Big Coal would be the battered boxer in the corner of the ring, shuffling away in an attempt to avoid the repeated jabs anti-coal warriors and scientists have been tossing its way. In 2009, not one new coal plant broke ground in the United States. Over 100 new plants were canceled or abandoned, largely due to the public's awareness that coal isn't the fuel of the future but a scourge of the past.
Clearly there is a reason for the coal industry's recent PR stunts. Big Coal is losing, and its best attempts to persuade the public about coal's green potential are failing miserably.
At the heart of "clean-coal" logic is the idea that carbon dioxide produced from burning coal can be captured and buried underground before it is ever released into the atmosphere where it will contribute to the earth's warming for centuries to come. Despite the fact that this technology, dubbed Carbon Capture and Storage (CCS), doesn't actually exist in any real capacity in the United States, it has not stopped the coal lobby from spreading the filthy myths.
Given the reality of climate change, Big Coal is banking on CCS to help it navigate its tenuous future, so much so that they are already touting the virtues of CCS to the public. Not surprisingly, the industry's pals in Washington, including virtually all the senators (Republican and Democrat alike) from coal-producing states, are going to bat for the beleaguered industry.
Certainly the effort to greenwash one of the most prolific and dirtiest energy sources on the planet does not come without a hefty price tag. The proposed Waxman-Markey climate bill, for example, is set to provide a whopping $60 billion in subsidies for "clean-coal" technologies. President Obama is on board and nary a word of opposition has peeped out of the Beltway. To put this amount of money in perspective, the coal industry itself, measured by its falling Wall Street stock, is only worth about $50 billion. The subsidies are a bailout by a different name.
In theory, in order for CCS to work, large underground geological formations would have to house this carbon dioxide. But according to a recent peer-reviewed article in the Society of Petroleum Engineers' publication, the CCS jig is up and the technology just doesn't seem feasible.
"Earlier published reports on the potential for sequestration fail to address the necessity of storing CO2 in a closed system," writes report author Professor Michael Economides in an editorial for the Casper, Wyoming, Star-Tribune. "Our calculations suggest that the volume of liquid or supercritical CO2 to be disposed cannot exceed more than about 1 percent of pore space. This will require from 5 to 20 times more underground reservoir volume than has been envisioned by many, including federal government laboratories, and it renders geologic sequestration of CO2 a profoundly non-feasible option for the management of CO2 emissions."
To put this in laymen's terms, the areas that would house carbon produced from coal plants will have to be much larger than originally predicted. So much so, in fact, that it makes CCS absolutely improbable. By Professor Economides' projections, a small 500 MW plant's underground CO2 reservoir would need to be the size of a small state like Vermont to even work.
"There is no need to research this subject any longer," adds Economides. "Let's try something else."
Let's take that a step further and add that we ought to bag the idea that coal can be clean altogether. The public investment in clean-coal technology is a fraud and will only serve as a life-support system for an industry that must be phased out completely over the course of the next two decades.
Putting billions of dollars behind a dead-end theory will not bring about the energy changes our country and climate so drastically need.

yea the coal industry are emitting an black cloud of an different sort , one to convince u everything is COOL WITH COAL here in kansas they wanted to enlarge an current coal powerplant last year but it was gunned down dead but now they are building an combination biomass ethanol plant and an ethanol powerplant combined to generate clean power the first of its kind in the nation i believe . we cant be lulled into believing that cheaper is the better way. Mcdonalds isnt like Ruth Chris steak house yes its cheaper but your health may suffer in the long run or your kids too

You will never, i repeat NEVER stop the coal trains. It isnt going to happen and you are beating a dead horse. All the shit you post here or any other site isnt going to change that. I have said it since I got here on current and I will continue to say it. The coal train will ride on. Ride baby ride. Must really piss you all of that the shithead in charge never had any intentions of changing this either.
RIDE BABY RIDE.......CHOO CHOO

" Clean coal " is the ultimate oxymoron intended to con retards.
In my Summer interim in 1967 between high school and college
I worked as a janitor at the Niagra Mohawk coal fired electric
power plant in Oswego, New York. I had to clean the locker room
where the men in the coal room hung their clothes, and took showers.
There was such an extreme amount of particulate matter floating in the
air there that I nearly gaged. And whenever I exited after moping the
blackened floors, the coal dust in the mucus in my nose was black.
Using the word " Clean " to describe anything involved with coal is
horse shit. I also worked for the City of Oswego constructing the
park on the scenic overlook to Lake Ontario. Ity was located directly
across the Oswego river where NiMo dumped the "slag" waste for
many, many decades. They basicly had dump trucks deposit loads
of topsoil over a hill made of slag so that green lawn could grow there.
Coal is all a con game to make Billions for the elite power broker gamers. - 2 years ago

To my ltd. knowledge, hydrogen may be one of the only substances
safe to convert, because it produces pure, fresh water, which is life.
And there will be an extreme shortage of fresh water in many parts
of the world due to global warming. (It's easier and cleaner to recycle
one's own urine than it is to reclaim all those Arctic/ Antarctic glaciers
calving icebergs the size of small countries to dilute all that fresh water
into the oceans.) I'm not even sure the Honda hydrogen car which
Kevin Spacey TV advertised for Honda in March 2008 realy even
" burns " the hydrogen. Though if I got it correctly, it ionizes it
somehow. Yeah, I know, WTF does that have to do with power plants.
Well, duh, a power plant is technically what they call a car engine.
So think on a much grander scale and you figure it out. - 2 years ago

Hydrogen, the ultimate answer. The problen lies at this time with the energy needed to create hydrogen is greater than produced. This is quite simply a technological challange that will be overcome with enough money for research invested. Its painfully obvious that big coal and big oil have no interest in being part of a clean energy revolution. This will require the federal government to start and fund the development of a process to extract hydrogen from water using less energy than produced until the hydrogen itself can fuel its own manufacturing. We will then be fossil fuel free, energy independent with an ever expanding economy because of it. Thats the way of the future if we in the words of Phil Knight.

Again... no.
We already have free energy sources (movement of tides, volcanic heat, sun, wind, bacterial synthesis, etc...) and hydrogen is just another fuel that we need to make by breaking apart precious resources. The sun provides limitless energy, in fact more than the entire planet needs on a daily basis. The technological challenge here is how to make solar capturing more efficient... which is already a quickly moving field of research. Efficiency ratings are going up every year for solar tech and, wind and non fuel burning sources are absolutely, without a doubt, the best uses for our time and money.
You still need plants to process hydrogen and pure oxygen is explosive... so if we take it from water, they have to store the oxygen somewhere safe. The technology isn't dynamic and it can't be easily transplanted to another country. Hydrogen processing also requires water... a resource we're already running low on. Around 1 billion people (or 2.5 billion by other estimates) go without access to clean water annually. So we're going to start converting it to fuel, then back into water as runoff from our engines... which still require oil to work. The plant itself will probably also require oil to run. You still have to transport the hydrogen fuel in heavy pressurized tanks, further increasing the footprint of it's production and use... and here's a quote:
"While it can be extracted from water, the cheapest source of hydrogen is natural gas, an unrenewable hydrocarbon. There's no distribution system or standardized method of storage, which is crucial since hydrogen fuel is a gas that must be kept under high pressure."
You think they'll end up going with the more expensive option for extraction? Doubtful. Which means we still need to mine and break up natural gas.
Anyway I've said it before already. Hydrogen is the next big thing from the minds that brought us petroleum. Don't buy into it. It's Bullshit. They're trying YET AGAIN to slowly dole out a new resource... when all of the energy we already need falls on us every day and can be easily and cheaply harnessed (you can make a windmill at home that could power your entire home cheaper than my monthly energy bill (about $500. I have lots of roommates :) ). Seriously.). The problem to the oil giants is that we don't get monthly bills that way. Hydrogen is more of the same. Forget hydrogen. We already have what we need... but the men on top don't want power to be free.

you do not need to use fresh water to extract hydrogen. Everything else you say has a degree odf truth to it. I never wrote my thread with the expectation of anyone deriving hydrogen from natural gas, that would be a catch 22. Wind and Sun can provide vast amounts of energy. But electric cars are not the answer right now, we are going to be saddled with tens of millions of used batteries from all the hybrids. Hydrogen derived from seawater, combustion of hydrogen produces water vapor. the cleanest technology to come. Wind will be able to produce a great deal of electricity, solar as well in the right parts of the country, that is until the next quantum leap in solar technology, then solar will be used everywhere.

I agree the future needs a lot of good solutions working together to actually produce some success... and I also agree that Hybrids are a bad call... in fact... cars in general will just never be made efficient at this rate. As much as I love the freedom of driving, it's clear that public transportation is another major piece of the puzzle.
I'm really hoping for teleportation, actually. :)
