    Strangely enough, the WA Liberal Government, despite being as apparently ambivalent about the reality of climate change as its NSW and Queensland counterparts, actually agreed for the WA coastal setback policy to be updated in line with more recent IPCC assessments. But that’s WA for you.

    It a move that seems intended to prove that climate denialism and sheer Stupidity are contagious, the Queensland government removes sea level rise from the real world:


    in direct imitation of another anti-science state government, and in sympathy with the nutters in North Carolina.

    I commented at the time about one of the liability issues that might arise – and I wonder who will be carrying the can in the future for the inevitable extreme costs that Newman’s magical thinking will impose on Queenslanders?

    I read and keep wondering about the failures of our education system.

    Fran: There is a wide range of renewable, low impact transportable fuels that can be produced starting from clean electricity. You might be interested in this post

    Thanks for the heads up John. There were some interesting ideas there for sure.

    One possibility you didn’t mention was the idea of using the process to “firm” intermittent sources of energy — such as wind or PV. Plainly, if you can ‘bottle’ electricity as fuel and you are “overbuilding” and reticulating wind/solar to ensure LOLP standards, then on those occasions when there is a surplus that cannot be sold commercially, one could use the surplus to create methanol to run generators to produce power outside of times when wind or insolation is available. If this turns out in lifecycle terms to be cost competitive with the other storage methods (and perhaps has a smaller footprint than new hydro/pumped storage, batteries etc) then we may be able to overbuild with a view to producing commercial quantities of methanol and get around the despatchability issues continually raised against renewables.

    I understand that in Iceland, they are taking their CO2 from industrial processes and also extracting substrates from the same place to produce commerical quantities of sulphuric acid that would otherwise be waste.

    I’ve also wondered whether, in producing H2, rather than cracking water, it might not be useful to crack urea, which has, after all, more ammonia in it and therefore an extra hydrogen atom. In places where animals are kept, or in sewage plants, there would surely be commercial quanttiies of the stuff. I’m not a chemist of course so perhaps I’m overlooking some technicality.

    Fran, it would be great if Japan could find a way to harness geothermal power (of which they have a lot) to do that carbon recycling thing with their industrial outputs (of which they also have a lot).

  8. John D

    Fran: My understanding is that they (Iceland) get the CO2 from the geothermal steam that is used to generate the cheap power used to make the hydrogen. At this stage of the clean-up process we could get CO2 from places like steelworks. (The big attraction of using liquid ammonia is that there is plenty of nitrogen – Extracting CO2 from air is a lot more difficult – The US navy was looking at extracting the CO2 required to make renewable jet fuel from sea water.
    I don’t know enough about the processes to comment on whether it is practical to use intermittent power.

    These posts are intended to share information and ideas about climate change and hence act as a roundtable for readers to contribute items of interest.

    Japan is going coal big time.

  10. John D

    Jumpy: In terms of emissions coal may actually be better than using LNG. Something like 25% of the energy in gas is consumed in converting it to liquid. Then there is transport energy, regasifying energy and fugitive emissions. The last time I looked there was little emission difference between using Qld coal to run ultra-critical power stations vs using Qld LNG in combined cycle gas.
    It is also worth noting that Japan has reached 10 gW of installed solar PV and that solar PV is increasing rapidly.
