Light relief for nerds


Turning to more serious matters Green Hydrogen is coming! Italy’s Enel expects to be producing green hydrogen within a year, with likely sites for its first wind and solar farms with electrolysers seen in the US, Chile and Spain, said Antonio Cammisecra, the company’s head of global power generation.

Wind Drought on Wednesday. At 3pm yesterday the wind was contributing 0.6% of electricity across SE Australia (the National Energy Market, who cares about WA?). The fans were running at 5% of capacity or less from 11 to 4.30 and under 10% from 2pm to 6pm. In Victoria (the wind leader, now far ahead of SA) the score was near zero from 3.30am to 6pm. In SA the capacity was under 5% all day to 6.30pm.

    The cooming cold weather will substantially reduce wind power output.

  2. Fast Facts on Hydrogen

    1) Smallest atom.

    Containing hydrogen requires precision engineering (expensive) to contain the smallest atom in the Universe. If it isn’t stored and transported correctly the gas escapes and can explode. BOOM!

    2) Near absolute zero

    Hydrogen must be cooled and stored at near absolute zero. That’s expensive and difficult.

    3) Production

    Hydrogen production requires vast quantities of clean water and electricity to produce, neither of these Australia has in surplus.

    Let the subsidies bandwagon roll on in!

    Italy’s Enel

    Nationalised power company which was then privatised.

    Anyone that’s worked for any of these knows they still operate like cumbersome state bureaucracy.

    We’ve bid some tools for some of their geothermal wells in Italy (and they started in Germany too) but it’s all bureaucratic tenders and bottom dollar shit so the cost of the bid is hardly worth it.

    Mike Ryan,
    I would like to clarify your statement:
    “Hydrogen must be cooled and stored at near absolute zero. That’s expensive and difficult.”
    No, it can be stored at any temperature, but to store any useful amount it must either be highly compressed in gaseous form (at about 10,000 psi) or ultra-cooled to liquid form. The former has the risk that the container can explode like a bomb if damaged, the latter that if steel is used to store it, it becomes brittle and likely to leak.
    In either case IMHO H2 is quite impractical and unsafe for widespread domestic and industrial use compared to liquid fossil fuels which are far safer and simpler to transport and store, and have an energy density (as Mj/litre) about 5-10 times greater than even liquefied H2. Energy from H2 is definitely not on my shopping list!

    Try telling that to a leftie like Morrison or Albanese.

    On the subject of Straya becoming a “clean energy superpower” it was most interesting to hear a passing mention in yesterday’s Press Club speech by Simon Birmingham that hydrogen exports “could” reach $11bn. p.a. by 2050 – so not exactly an alternative source of revenue for a big-spending nation in which some want to close down the coal and gas export industries now (not in 30 years time).
