Energy Secretary Chu Endorses "Clean Coal"

DesScorp writes "The Wall Street Journal is reporting that Energy Secretary Steven Chu is endorsing 'clean coal' technology and research, and is taking a pragmatic approach to coal as an energy supply. '"It absolutely is worthwhile to invest in carbon capture and storage because we are not in a vacuum," Mr. Chu told reporters Tuesday following an appearance at an Energy Information Administration conference. "Even if the United States or Europe turns its back on coal, India and China will not," he said. Mr. Chu added that "quite frankly I doubt if the United States will turn its back on coal. We are generating over 50% of our electrical energy from coal."' The United States has the world's largest reserves of coal. Secretary Chu has reversed his positions on coal and nuclear power, previously opposing them, and once calling coal 'My worst nightmare.'"

      From the recycling article regarding the US and reprocessing. "In October 1976, fear of nuclear weapons proliferation (especially after India demonstrated nuclear weapons capabilities using reprocessing technology) led President Gerald Ford to issue a Presidential directive to indefinitely suspend the commercial reprocessing and recycling of plutonium in the U.S. This was confirmed by President Jimmy Carter in 1977. After that, only countries that already had large investments in reprocessing infrastructure continued to reprocess spent nuclear fuel. President Reagan lifted the ban in 1981, but did not provide the substantial subsidy that would have been necessary to start up commercial reprocessing."

      We should put nuclear waste on rockets and shoot them into space.

      Why? By weight, 90% of the spent fuel is natural uranium, which can be used as fuel in fast reactors or other commercial purposes. 5% of the weight is high-level radioactive waste, which decays to safe levels in a few decades. The rest is trans-uranics, which can be recycled to use in new fuel.

      The only reason why we have a "waste problem" in the US is because the government won't allow separating the dangerous-part-which-decays-quickly from the very-long-half-life-but-reusable-as-fuel parts. The reason why we can't do this separation is because we don't want to encourage rogue nations like Iran and North Korea from developing nuclear weapons.

      One of the problems is mining of coal. That isn't as clean or safe as it could (or should) be. The mass strip mine operations have given way to mountaintop removal which gets really ugly if the mining company can't (or won't) control runoff from the site. That's a very good way for people's water supply to turn orange if they use local wellwater for anything.

      The other problem is the amount of energy it takes to store up CO2 somewhere. Realistically speaking we're going to need lots of dense (preferably mineral) carbon in the future for when carbon nanotubes (and similar carbon nanomaterials) take off, and burning coal sort of makes it harder to utilize all the raw carbon locked inside. Anthracite can be up to 98% pure carbon. Converting all that into CO2 + energy and then attempting to produce nanotubes from all that CO2 is sort of backwards. Better just to harvest all the raw carbon and throw the rest away.

      Understandably that is a different application than energy production but coal will be one of the most attractive sources of carbon for nanotubes in my opinion (up there with graphite).

      One the problem with "clean" coal is the radioactive waste. For the amount of energy produced, coal created more radioactive waste then nuclear. The difference is it is mixed in with tons and tons of chemically toxic ash, so there is no way of ever disposing of it safely. For nuclear energy the waste is conveniently concentrated and small enough it can be disposed of safely in stable rock.

      Perhaps if we mixed the waste from our reactors with coal ash, people won't be so worried about it.

      Absolutely right. CO2 is the one chemical that can't seem to be scrubbed out. I work for Babcock Power, and I can tell you that Alcoa Is working with us on some technology to handle that. But the guys I know working in that department say that the technology is at least 7 years away. Management won't task more of us on the project either. We sell systems that we can guarantee will remove 98% of mercury, several SOX, carbon, sulfur and Sulphuric Acid, aluminum, but not CO2. It's the one thing left coming out of smoke stacks in america. I love how we sell 90 of these things every year but people keep complaining that there is no clean coal. After we get rid of the CO2 I swear I expect them to complain about the water vapor next. And no that was not a joke. I would like to point out that the real problem is in how the government classifies a station as "clean". Lets say that power company a has 30 stations. They each generate "points" on a point system developed by the feds. There is a chart that says they must have a certain number of points, depending on the number of stations, that will qualify them to be clean. These companies will invest in our systems to the minimum extent possible to qualify, and then leave the other stations dirty. It is usually less than half of their systems. There is so much I could tell you guys, I had no idea you were interested in clean power. I thought this was a technology site, but I guess it is more broad than that. BTW those wikipedia articles are almost completely wrong, the systems I am working on don't work anything like how they describe, not even close. The ones from our competitors don't work that way either. If those articles are what slashdot is basing it's opinions on I can understand why there is so much confusion. The funny thing is that we are based in MA, and we are selling more of these in the middle east than we are here in the US. They pay us in gold. Real gold. They have so much money floating around over there that they can invest in hundreds of these systems every year, and that is where the real innovation is happening. The power industry in India far outpaces our own, it's actually amazing how much work they have done in the last two decades. If the point system went away, if a legislator grew the balls to do it that is, then all of the power grid in america could be clean within 5 years. The problem is they don't have to buy any more than they need to qualify for the tax credit. That is equivalent to Toyota only putting in enough seat belts to qualify for a tax credit, instead of putting them in every seat because it is the right thing to do.

    Chu is not anti-nuke. I don't know where you got that idea, but Secretary Chu has long been a proponent of nuclear power. From a 2005 interview with UC Berkeley's Bonnie Azab Powell:

    Question: Should fission-based nuclear power plants be made a bigger part of the energy-producing portfolio?

    Chu: Absolutely. Right now about 20 percent of our power comes from nuclear; there have been no new nuclear plants built since the early '70s. The real rational fears against nuclear power are about the long-term waste problem and [nuclear] proliferation. The technology of separating [used fuel from still-viable fuel] and putting the good stuff back in to the reactor can also be used to make bomb material.

    And then there's the waste problem: with future nuclear power plants, we've got to recycle the waste. Why? Because if you take all the waste we have now from our civilian and military nuclear operations, we'd fill up Yucca Mountain. ... So we need three or four Yucca Mountains. Well, we don't have three or four Yucca Mountains. The other thing is that storing the fuel at Yucca Mountain is supposed to be safe for 10,000 years. But the current best estimates - and these are really estimates, the Lab's in fact - is that the metal casings [containing the waste] will probably fail on a scale of 5,000 years, plus or minus 2. That's still a long time, and then after that the idea was that the very dense rock, very far away from the water table will contain it, so that by the time it finally leaks down to the water table and gets out the radioactivity will have mostly decayed.

    Suppose instead that we can reduce the lifetime of the radioactive waste by a factor of 1,000. So it goes from a couple-hundred-thousand-year problem to a thousand-year problem. At a thousand years, even though that's still a long time, it's in the realm that we can monitor - we don't need Yucca Mountain.

    Question: And all of a sudden the risk-benefit equation looks pretty good for nuclear.

    Chu: Right now, compared to conventional coal, it looks good - what are the lesser of two evils? But if we can reduce the volume and the lifetime of the waste, that would tip it very much against conventional coal.
