Malcolm Turnbull has now, for reasons best known to himself, elevated “energy crisis” to a “national security” issue. Ben Potter puts the situation well:
A decade of fighting over renewable energy, carbon prices and fossil fuels has left Australia with some of the world’s dirtiest and costliest energy – a bitter yield from historical abundance.
Three years ago, manufacturers began complaining they couldn’t get gas, and 18 months ago the South Australian grid started to wobble.
Now, electricity and gas prices across the eastern states are two to three times their levels only a couple of years ago.
Gas exporters overcommitted to foreign buyers; the federal government mismanaged renewable energy and the regulatory apparatus – and politicians responsible for it – are frozen in the headlights.

The innovative LiquidPiston engine, mentioned by BilB, is targetting a global market worth $460 billion. It has a power to weight ratio more than ten times better than a regular engine:
The big bruiser on the left puts out 35 HP, the one on the right 40 HP. Continue reading Climate clippings 198

David Leitch’s article Battery storage: Bad advice about costs is fooling Australian governments reviews two American reports on grid-scale battery storage in the states of Texas and Massachusetts. He says the reports:
are detailed, professionally modelled and far more forward looking and sophisticated than anything so far produced by traditional Australian electricity consultants such as Jacobs, Frontier, IES, Ernst & Young or ACIL Allen.
Leitch, the principal of ITK says in their view:
Australia is being held back, in part, because consultants in Australia provide advice to federal and state governments based on expensive models that are basically out of date. The models don’t, and in fact can’t, take an integrated (whole of system) view.

Bloomberg is warning that the multi-trillion-dollar ‘big crash’ in oil investments could start as soon as 2023. However, the smart money is bound to move earlier. Here’s the progress of electric car sales:

In what is called ‘attribution science’ climate scientists are getting better at analysing how much climate change has influenced particular extreme weather events.
In short, it is no longer a question of weather there is an influence, rather how much.
It would be useful to know, for example, whether the kind of storm that hit South Australia is still a once in 50 years event. Continue reading Climate clippings 185
The latest Morgan Stanley report is bullish about the growth of battery storage in the Australian market. They think we’ll have 6.6GWh of battery storage in Australia by 2020, which is what the Australian Energy Market Operator last week predicted for 2035. Continue reading Climate clippings 176
The Powerwall is a 7 kilowatt hour (kWh) lithium-ion-battery system that stores electricity generated from rooftop solar panels (or PV panels) during the day so that electricity can be used at night during the peak-usage times.
Most existing solar panel owners will need to obtain a new inverter to connect with the grid. Continue reading Climate clippings 163
The momentum at present is with lithium-iron batteries, which are being used in devices from mobile phones to electric cars. Since the technology was commercialised in 1991 its performance has improved immensely – design tweaks have tripled the energy stored in a given volume.
