The Australian Energy Regulator is locking horns with the Australian Energy Market Operator over phasing out coal-powered electricity.

Blah, blah, blah, why does this endless sermon disregard that big old coal fired power can only be run at 100%? Reduced power means low pressure steam danger if condensed water droplets preening turbine blades. Especially with brown coal, quality variations do cause danger of reduced output. Boilers are the height of 20 storey buildings. Conflict between more steam tubes and ash build up and bridging, corrected by shutdown, cool down scaffolding and jack hammers. Corrosion inside as well as outside of boiler tubes, leaks causing ash set like concrete. With Hazelwood, 8 x 200MW turbines, possible to reduce some to idle but newer 500MW are all or nothing.
Does AER not understand nature of problem, ever worse beyond 40 year use by date.
ARENA opens up to $40m in funding to expressions of interest from projects that promise to materially reduce the levelised cost of solar.

“ARENA said the R&D funding program would be aligned with the Agency’s own ambitious target of ‘Solar 30 30 30’, to improve solar cell efficiency to 30 per cent and reduce the total cost of construction of utility scale solar farms to 30 cents per watt by 2030.” Not good news for fossils.
23 August, 2021 − Trees are vital for solving the climate crisis. But there’s nothing simple about the forested world, as forest people know.

A must read, extra context, next time drought in Murray Darling is news, reflect on 18 to 24Billion trees now down to 8Billion and tree farming not much help compared with way Nature can make recovery
Projects proposing to make hydrogen where sunshine and wind are constant & ship it to where energy is needed are based on hand-waving, ignorance or larceny.

Originally, advantage here was so much land space for onshore wind farms. But now offshore proven to be competitive. Boris and little old UK boasting they’re set to be Saudi for hydrogen. Same again for any country adjacent to ocean.
Pity so much H2 obsession with Scomo.

Coal is likely to be completely gone from Victoria’s electricity system by 2032 with most other parts of Australia not far behindPrime Minister Scott Morrison says Australia’s emissions have come down 20 per cent, a record he says is beaten by only four other countries in the G20. Is that correct? RMIT ABC Fact Check investigates.

looks like so much insistence emission reduction success is proverbial “last refuge of a scoundrel”
