American Clean Power ?

Please stop talking about Clean Coal as some kind of solution for energy independence and/or global warming issues.  It can not do either of these.  Let’s use some common sense.  Coal to replace gasoline ?  Coal to replace home heating oil?  We could build more coal fired electricity generating plants, but that does not reduce our dependency on foreign oil for the other two needs.

The picture used on the left comes from the ACCCE, a new group funded by Coal and Energy companies.  They are in the process of spending millions of dollars on ad campaigns to tell you

1.) Coal generates %50 of our electricity 2.) Coal is cleaner and can be even cleaner with investment in technology.  They run ads on TV, they have a web site http://www.americaspower.org/ Thanks for Sharing!

Clean coal !  Please.  Is there such a thing as clean coal ? It does seem peculiar to me that both Presidential candidates highlight Clean Coal, some oil drilling and nuclear plants (McCain, not Obama), for our short term energy solutions.  Other technologies are always mentioned as an afterthought, oh, yeah, “some of that Solar and Wind stuff too”. One characteristic of the commonly mentioned technologies is they exist (not clean coal), and they are backed by large existing corporate and union interests. I am sure that is just a coincidence.

Clean Coal is NOT ready for prime time.  The more we try to make old solutions work, the more money, time and energy we take away from building RENEWABLE solutions.  What is renewable about Coal, even if it was Clean.  Nothing.  It is currently plentiful so let’s use it, is the logic.  Talk about clinging to beliefs.

The same reasons many conservatives knock newer renewable energy sources, such as ‘it is not ready’, ‘it will not scale’, ‘it is to expensive’, ‘it is unproven technology’…. All apply to clean coal.

The three technologies currently being researched and mostly in a pilot phase are;

Clean it, Filter it, and Capture it.

‘IT’ is nitrous oxide, sulfur dioxide, carbon dioxide and of course your everyday mercury and other metals.

Clean it, consists of a bath for the coal prior to using.  It removes much of the sulfur, and some of nitrous oxide, BUT, it leaves a nice slurry of waste water that goes somewhere…oh yeah, in the ground, in a river, in the environment.  It does nothing to reduce carbon dioxide.

Filter it, means catalytic converter type filtering on the smokestake, or new oxygen purification systems where they cook the pollutants in a bath of oxygen.  This second approach is more effective but expensive.

Capture it, means Carbon Sequestration.  Even Al Gore talked about this during his powerpoint theater.  Is it just me, or does capturing the carbon dioxide and pumping it into the ground or better yet into active oil reserves make any sense ?  What a stupid idea.

I want to believe technology can solve most problems, and maybe it can reduce emissions so that Burning Coal produces NO pollutents.  But until that comes closer to reality, just shut up, and focus on alternative energies that actually work NOW and are clean.

Proposal: In the short term focus on Methane reduction. Mid to Longer term focus on CO2 reductions.

Why?

Atul Jain, a U. of I. atmospheric scientist says;

“Most of these methane abatement technologies can be quickly implemented with existing technologies,”

“Because of its short atmospheric response time of about 12 years, methane concentrations will respond quickly to emission reductions, producing an immediate and significant impact on climate change”

There are five major sources of man-made methane in the United States — landfills, coal mining, bovine emissions, manure systems and the production and transmission of natural gas. A significant amount of these emissions can be reduced through the use of currently available, economically justified and easily verified options. Such options include capturing the methane and recovering the cost of the emission-reduction technology by selling the gas or using it to displace other energy inputs.

My favorite – Bovine ‘emissions’ – “Agriculture is responsible for producing 37 percent of global methane emissions, a gas that is 23 times more potent than CO2 when it comes to global warming. And much of this gas comes from the burps of ruminating animals such as cows and sheep. If a cow’s manners could be improved a bit, then the world might just stop warming quite so fast. And it could be as simple as getting them to graze on different types of plants. Scientists at the University of Aberystwyth are now working on using plant-breeding methods to develop new diets for livestock.

“Normally a cow’s stomach is pretty inefficient — 80 percent of food ingested comes out as waste or methane. The average cow produces between 300 and 500 liters of methane a day, most of it through belching. “There is a common misperception about how methane gets into the atmosphere,” Michael Abberton, a scientist at the Aberystwsth’s Institute of Grassland and Environmental Research, said Monday. “It is actually through belching rather than the other end.”

Abberton told a briefing on farming and climate change at London’s Science Media Center that the key could be developing new varieties of legumes and grass, as well as planting more clover and birdsfoot trefoil, a common wildflower. These could change the way the bacteria in the cow’s gut breaks down food. According to the scientist, developing new varieties of plants which are easier to digest could allow farmers to avoid reducing stock while still cutting methane emissions.

Gee, easier to grow, easier to digest = easier to breathe.
