Coal-to-Liquid: Useless

Byoliveridley

Liquid transportation fuels derived from coal and natural gas could help the United States reduce its dependence on petroleum. The fuels could be produced domestically or imported from fossil fuel-rich countries. The goal of this paper is to determine the life-cycle GHG emissions of coal- and natural gas-based Fischer−Tropsch (FT) liquids, as well as to compare production costs. The results show that the use of coal- or natural gas-based FT liquids will likely lead to significant increases in greenhouse gas (GHG) emissions compared to petroleum-based fuels. In a best-case scenario, coal- or natural gas-based FT-liquids have emissions only comparable to petroleum-based fuels. In addition, the economic advantages of gas-to-liquid (GTL) fuels are not obvious: there is a narrow range of petroleum and natural gas prices at which GTL fuels would be competitive with petroleum-based fuels. CTL fuels are generally cheaper than petroleum-based fuels. However, recent reports suggest there is uncertainty about the availability of economically viable coal resources in the United States. If the U.S. has a goal of increasing its energy security, and at the same time significantly reducing its GHG emissions, neither CTL nor GTL consumption seem a reasonable path to follow.

Comparative Analysis of the Production Costs and Life-Cycle GHG Emissions of FT Liquid Fuels from Coal and Natural Gas.

To summarize, no cost benefits, increased GHG emissions, a lot of uncertainty, let’s not follow this madness of trying to make coal into gasoline.

    China, India and the other developing nations are upset that commitments to provide financial and technological help made during a U.N. conference in Bali, Indonesia, in 2007 have not translated into anything more tangible.

    Mr. Meyer estimated that the United States, Europe and other industrial nations need to come up with $150 billion a year in assistance by 2020 to help develop clean energy technology for developing countries, reduce deforestation that contributes to rising temperatures, and help vulnerable nations adapt to changes attributed to greenhouse gases.

    G-8 Nations Fail to Agree on Climate Change Plan – NYTimes.com

    Yes, it is true, North America and Europe are responsible for a bulk of the greenhouse gas emissions currently in the atmosphere and need to do the bulk of the work. But it would also behoove India and China to make the right noises. There is no sense that we’re in this together, that we will all be affected, and India and China even more so

    Leadership is lacking, the US needs to take a first big step and start things of.

    Update

    The G8 has agreed to sign on to a limit on warming of 2°C rise in global temperature. Well, how do you get there without reducing CO2 in the atmosphere, which we apparently can’t agree to do? It’s like saying you need to go a 100km more on a road trip, but refusing to agree to fill gas.

    There is a chicken and egg problem here. The famously resistant to change US system is working through a climate bill. The world is waiting to see what will happen, but the version of the bill passed by Congress is not strong enough to avert a 2°C rise unless China and India are as aggressive and there is massive technological shift away from fossil fuels. The US system is waiting for signals from the world, reasoning they don’t want to act first and unilaterally. It’s all nice game theory for people watching from the sidelines, but life’s a little more serious…

    Water Find to End Darfur War – Well, not so fast!

    Byoliveridley

    Beware the dangers of the overhyped press release machine (or sciencedaily, pick your poison). All Farouk El-Baz saw when he did the radar study was a giant depression. It is TBD whether there’s water in them thar holes!’

    BBC NEWS | Africa | Ancient Darfur lake is dried up

    Alain Gachet, who used satellite images and radar in his research, said the area received too little rain and had the wrong rock types for water storage. But the French geologist said there was enough water elsewhere in Darfur to end the fighting and rebuild the economy.

    On Wednesday, Boston Universitys Farouk El-Baz said he had received the backing of Sudans government to begin drilling for water in the newly-discovered lake, in North Darfur.

    No wonder they say that water is the 21st century oil. This guy’s going to be drilling for water (also known as well digging!).

    Endocrine Disrupting Chemicals – A new Resource

    Byoliveridley

    Critical Windows of Development is a timeline of how the human body develops in the womb, with animal research showing when low-dose exposure to endocrine disrupting chemicals during development results in altered health outcomes.

    Critical Windows of Development

    This promises to be an easy to use database showing development timelines of infants, and the documented effects of endocrine disrupting chemicals at these timelines. The prime focus is bisphenol A and phthalates at this point in time. The Environmental Health News has more about the program here. It is not out for public consumption yet, so stay tuned…

    Ionic Air Purifiers may actually Increase Particle Concentrations

    Byoliveridley

    Take that, Sharper Image, your air purifiers that you waste tons of paper sending me monthly catalogs for don’t work. The ones that use ozone react with organic compounds in the air, especially your fragrances in cleaning products, air fresheners and perfumes to make fine particles in that crucial 0.1-1 um size range that your lungs don’t clear very effectively.

    Not a big deal in the grand scheme of things, especially with other indoor pollutants. But I always thought these air purifiers were a scam, I am glad somebody actually got the NSF to fund this study and get some proof!

    Kinetic Analysis of Competition between Aerosol Particle Removal and Generation by Ionization Air Purifiers

    Kinetic Analysis of Competition between Aerosol Particle Removal and Generation by Ionization Air Purifiers

    Ahmad Alshawa, Ashley R. Russell, and Sergey A. Nizkorodov*

    Department of Chemistry, University of California, Irvine, California 92697-2025

    Abstract:

    Ionization air purifiers are increasingly used to remove aerosol particles from indoor air. However, certain ionization air purifiers also emit ozone. Reactions between the emitted ozone and unsaturated volatile organic compounds (VOC) commonly found in indoor air produce additional respirable aerosol particles in the ultrafine (This model predicts that certain widely used ionization air purifiers may actually increase the mass concentration of fine and ultrafine particulates in the presence of common unsaturated VOC, such as limonene contained in many household cleaning products. This prediction is supported by an explicit observation of ultrafine particle nucleation events caused by the addition of D-limonene to a ventilated office room equipped with a common ionization air purifier.

  • Dear American Public Media, Coal is not clean!

    Byoliveridley

    Overheard this morning on The Marketplace morning report…

    “The use of scrubbers have made coal fired power plants much cleaner”

    Umm, this only refers to the scrubbing of particulate matter and sulfur dioxide. Unless some marvelous scrubber has been invented and perfected (top secret, the coal fired power plants don’t want you to know about all the good things they do!) that picks up all the CO2 belching out of those smokestacks, no claim can be made that coal is cleaner.

    Dear Marketplace, your own website says the following:

    KAI RYSSDAL: And it’s official. Carbon dioxide is a pollutant. The Supreme Court says so. The Bush Administration had been arguing the Environmental Protection Agency doesn’t have the authority to regulate greenhouse gases

    To argue this from a strictly legalistic standpoint, coal is dirtier now than it has ever been because we finally count CO2 as a pollutant (Yes, I know, Supreme Court only ruled on automobile emissions because that was the case in front of it, but gas is gas!).

    Dear Marketplace, please stop using the words clean and coal in the same sentence unless and until CO2 emissions from coal are scrubbed!

    Update 30Aug07: Apparently (see comments!), NPR does not like the use of the word NPR in the blog title because (and I quote)

    “Marketplace” is not an NPR show. It is produced by American Public Media, a separate company, and has its own news operation”

    True, so it’s not dear NPR anymore, it’s “dear American Public Media”. There, that takes care of that. My point obviously stands, coal is not clean!!

    FDA decides to breed super bugs

    Byoliveridley

    Well, what else can you say about it. This is insanely moronic. Read this sierra club release about the overuse of antibiotics brought on by the overcrowding of animals in food production factories (aka “farms”). Read the whole article and see how much everyone will be endangered so that Intervet, Inc. can make money.

    FDA Rules Override Warnings About Drug – washingtonpost.com

    The government is on track to approve a new antibiotic to treat a pneumonia-like disease in cattle, despite warnings from health groups and a majority of the agency’s own expert advisers that the decision will be dangerous for people. The drug, called cefquinome, belongs to a class of highly potent antibiotics that are among medicine’s last defenses against several serious human infections. No drug from that class has been approved in the United States for use in animals.

    Note, a powerful and potent antibiotic that works well, but is not used much because it’s the last line of defense. But the drug company that manufactures this product cares little about long term efficacy. Their only goal is to maximize short term shareholder value. I don’t blame them, I blame the government for not doing its job, that is, to balance these short term and long term goals and protect the people that pay them a lot of money for this protection.

    The wording of “Guidance for Industry #152” was crafted within the FDA after a long struggle. In the end, the agency adopted language that, for drugs like cefquinome, is more deferential to pharmaceutical companies than is recommended by the World Health Organization.

    Cefquinome’s seemingly inexorable march to market shows how a few words in an obscure regulatory document can sway the government’s approach to protecting public health.

    There’s a reason this present U.S government works in secrecy, so these “obscure” (I am sorry, but nothing that directly affects human health can be called obscure) rule changes will not hit the public eye before it’s too late. Apparently, the FDA can now only consider resistance to food borne diseases in considering an application. That’s like saying that a hospital will only treat victims of food borne diseases, so if you catch the cold, we won’t treat you! This is the Food and Drug Adminstration (all food and all drugs), not the food borne disease protection council.

    This drug is absolutely unnecessary for the following reasons:

    1. The disease it treats (respiratory distress in cows) is brought about by insane levels of animal overcrowding
    2. There are currently a dozen antibiotics for this particular problem, none of which are considered susceptible to resistance
    3. The FDA has previous history with similar public health threats with fluoroquinolones
    4. This drug is considered a last resort drug for antibiotic resistant strains of diseases in cancer patients – So strains resistant to this drug will evolve shortly after the antibiotic is overexposed . This is a death sentence for a lot of very vulnerable people.
    5. A similar drug used in Europe for the last 10 years has resulted in an increase in resistant strains of bacteria.

    This is what you get when you vote for an ideology that hates government. You get a government that hates itself and is busy pawning parts of itself off to its cronies.
