Coal -The hard facts

It really is time  to wake  up to the reality of increasing coal consumption and carbon emissions. This  was recently addressed by  Maria van der Hoeven of the IEA who gave a speech to launch the “Medium Term Coal Market Report 2013” in Paris last  Monday 16th Dec. Much the same points have also made by Dieter Helm in his book “The Carbon Crunch”.

  • Coal is abundant and geopolitically secure. Coal-fired plants are easily integrated into existing power systems. No fuel draws the same ire, particularly for its polluting qualities both locally and in terms of greenhouse gas emissions. And yet no fuel is as responsible for powering the economic growth that has pulled billions out of poverty in the past decades.
  • Over the next six years, additional coal production capacity of a half million tonnes per annum will be added worldwide each and every day. Coal prices are also falling. Coal price in ASIA is $4/mBTU   whereas LNG prices are  $16/mBTU – 400% higher. Indonesia has vast coal reserves.

  • More than 60% of the rise in CO2 emissions since 2000 is due to burning of coal to produce electricity and heat. This rise in emissions is  occurring in ASEAN countries.
  • In China, the scale of coal in the economy is simply incomparable to fuels elsewhere. Replacing coal with gas in Chinese power generation would require twice the volume of all global LNG trade. Coal  therefore  will continue  to  play  an  important  role  in economic  growth  and  energy  security worldwide.

  • If just the new coal plants under development in India and Indonesia were instead to be completed using latest technology it would save as much CO2 as all the wind turbines in Europe combined. Technical subsidies by Europe to achieve this would be a far cheaper means to tackle climate change than are current policies.

Whenever you see the Keeling curve of ever increasing CO2 levels just remember that nearly 2/3 of that is due to coal burning in Asia. What can be done about it?  In the short term nothing can be done and carbon emissions are sure to rise for the next few decades whatever we do in Europe.  It means that Europe’s efforts to cut emissions are essentially futile.  There are only two ways out of this dilemma long term:

  1. International carbon price. This needs to make coal  artificially 3 times more expensive than it actually is to encourage a switch to gas. I don’t think there is a hope in hell of getting developing countries to agree to that – and anyway who would be the recipient of these trillions of dollars ?
  2. Underground gasification of coal to methane. This could halve carbon emissions and avoid air pollution but at the expense of lower yields. Only an international agreement similar to banning the use of CFCs would achieve this.

The scale of the growth in coal consumption in Asia is staggering. It really makes a mockery of Europe’s de-carbonization policies.  For energy security reasons the UK should have built a couple of modern efficient coal plants just like Germany and Holland did within EU limits and thereby save on  energy bills.  However, Friends of the Earth stopped the Kingsnorth plant in Kent from being developed by E-on in 2009, and shortly after the UK government essentially blocked any new coal plants without CCS and introduced a stealth carbon floor tax penalizing coal further. Meanwhile any progress on CCS is essentially stalled and the UK faces power curs in 2014/2015. One reason for that is that 30-40% of the output power is needed to drive CCS !

    There is no problem with adding more CO2 tot the Atmosphere, it just makes the plants grow quicker & bigger.

    • Clive Best says:

      All things being equal doubling CO2 in the atmosphere would cause a 1C rise in surface temperatures. This is fairly straightforward physics. However, what happens in reality is still unsure and possibly clouds are a negative feedback. In any case a 1C rise in temperatures would probably be beneficial and the extra CO2 encourages plant growth. You need to accept extreme feedback scenarios from models to get anything ‘dangerous’. The data does not support these extremes.

      • Roger Andrews says:

        According to this study by Richard Tol the economic impacts of global warming are positive if the warming stays below 2C.

      • Shooter says:

        “This is fairly straightforward physics” – No it isn’t, it’s physically impossible. CO2 has never been proven to raise temperatures. It does the opposite. Plus, no gas can “trap” heat, that is physically impossible.

        To say that a “doubling of CO2 will raise the temperature” is incorrect.

  2. A C Osborn says:

    Are you sure about the 1C rise overall?
    Have you seen the AGU video by NASA here
    http://wattsupwiththat.com/2013/12/13/leif-svalgaard-at-agu-on-the-current-solar-cycle-none-of-us-alive-have-ever-seen-such-a-weak-cycle/

    See the section by Marty Mlynczak about CO2 cooling the Thermosphere.

    • bob Peckham says:

      Thanks for pointing out the very interesting video. If you watch it to the end there are questions, and there is a specific question about the effects on surface temperatures. The answer is that the cooling effect of CO2 high up is too small to have a noticeable affect on surface temperatures, being of the order of milliwatts per sq.m. (If I understood it correctly)

    The point is that they have evidence and proof of the Cooling, but none for the warming by CO2 lower down, only the greenhouse gas theory.

    Dear Dr.Clive Best:

    How do you do?
    I have read your interesting post “Coal-The hard facts”.
    After Fukushima nuclear disaster,hot debates are going on
    as to the energy mix in Japan. Since AGW theory is a fictitious
    science, I believe coal is the best choice in terms of resources
    quantity, electricity generating cost and safety problem.
    If you mail to me, I can send you a E&E paper showing a basic
    error of IPCC’s AGW scheme together with several essays posted
    to “Climate Clash” (http://climateclash.com/).
    I would like to have your comments on my ideas.

    Sincerely,
    Mr.Kyoji Kimoto

      Currently in Asia coal is the cheapest fuel. Germany is building 9 new modern coal stations which limit pollution and reduce CO2 emissions within EU regulations. Clean coal and gas (even with CCS) make sense in Japan short term but can only be intermediate solutions for the next 100 years or so. Climate change may not turn out to be a big problem but eventually fossil fuels will become scarce so we should prepare alternatives. Renewables will never work in Japan, so new generation nuclear still makes a lot of sense. The Fukushima nuclear disaster was a chain of linked mistakes. If only the emergency generators had been put on the roof everything would have been all right. This is no reason to reject nuclear “per se” as I can’t see any other long term alternative.

      I would reopen existing nuclear plants as soon as possible following safety checks and transfer funds away from renewables to research alternative nuclear. We have time to get it right and should reject alarmist claims to de-carbonise now, because they lead to pre-industrial lifestyles.

      • Bob Peckham says:

        Hi Clive.
        You say “even with CCS” , but wouldn’t it be better still to skip the CCS and not waste precious fuel resources in futile pumping, redirect that investment to better use, and let the CO2 feed enhanced forest growth and crop growth ?
        Bob P.

        • Clive Best says:

          Yes Bob – we could build huge greenhouses next to coal stations and simply pump the CO2 there to dramatically increase crop yields !

          I don’t think all those green environmentalists would be too happy though. They are determined to return to the garden of Eden.
