It is true that renewables have an immense road ahead, but we already know the destination, Net Zero, in all areas of life, so why keep throwing good money after bad with fossil fuels.
I show exactly where we are with renewables and storage, and indeed it is woefully short, but I also show how we could take the initiative and the right decisions to clean our energy supply as early as 2030.
There is big money trying to wring out every last penny of profit from their declining empires, and using politicians on their pay to do their dirty work, but we can decide where we spend our money, and we can harass the companies to do more and faster, and we can make a better future for all of us.
Neoen reveals plans for another big battery in South Australia which could be even bigger than the Victorian Big Battery opened on Wednesday.
French renewable energy and battery storage developer Neoen, fresh from the formal opening of the Victorian Big Battery – the biggest in Australia to date – has revealed plans for a potentially even bigger battery in South Australia.
Neoen is due to hold a community open day on Thursday for the Blyth battery, which will be sized up to 300MW and 800MWh, trumping the 300MW/450MWh capacity of the newly opened VBB near Geelong.
The Blyth battery will be located west of the town of Blyth, north of Adelaide, and alongside the existing Blyth West sub station, which have now become prime sites for aspiring battery storage developers.
British utility SSE and Norwegian energy giant Equinor announced late last week that they have secured financing to proceed with the construction of the $3.98 billion Dogger Bank C offshore wind farm off England’s northeast coast.
Dogger Bank C offshore wind farm, along with Dogger Bank A and Dogger Bank B, is due to become the largest offshore wind farm in the world upon completion, with an installed capacity of 3.6 gigawatts (GW). Each phase is 1.2 GW.
Dogger Bank C will generate around 6,000 gigawatt hours (GWh) of electricity a year when completed in 2026.
The FlyZero aircraft is one of a range of aircraft being designed by the FlyZero program. The new concept will store hydrogen in cryogenic fuel tanks, keeping them at a temperature of minus 250°Celsius (minus 418°Fahrenheit). Two cryogenic tanks will be placed at the rear of the plane, while two smaller “cheek” tanks will be placed near the front of the plane to keep the aircraft balanced. The mid-size aircraft will have a wingspan of 54 meters, each of which will have a turbofan engine attached.
“These designs could define the future of aerospace and aviation,” said U.K. Business Secretary Kwasi Kwarteng in the ATI’s statement. “By working with industry, we are showing that truly carbon-free flight could be possible, with hydrogen a frontrunner to replace conventional fossil fuels.”
In its statement, the ATI estimates that “highly-efficient hydrogen-powered aircraft” will “have superior operating economics compared to conventional aircraft from the mid-2030s onwards.” The ATI has received £1.95 billion ($2.6 billion) in funding since it was founded in 2013. The FlyZero concept program, which received £15 million of that funding, promises to allow travelers to fly with the same speed and comfort provided by airliners today.

The 279-seater could fly from London to San Francisco without refueling. A U.K. government-backed research firm, Aerospace Technology Institute (ATI), revealed a new liquid-hydrogen-powered airliner concept called FlyZero.
Alinta unveils plans to build 1,000MW offshore wind farm near Portland to help deliver 100 per cent renewable energy supply to local aluminium smelter.
Alinta Energy is proposing a 1,000MW wind farm off the coast of Portland in Victoria that could help power the Portland aluminium smelter with up to 100 per cent renewables, and inject green energy into the country’s main grid.
Spinifex would connect to the grid via the smelter’s switchyard – which accounts for more than 10 per cent of the state’s electricity demand – and make the site among Australia’s first smelters to be powered by up to 100 per cent renewables.
Abstract: Here we show that precise Gaia EDR3 proper motions have provided robust estimates of 3D velocities, angular momentum and total energy for 40 Milky Way dwarfs. The results are statistically robust and are independent of the Milky Way mass profile. Dwarfs do not behave like long-lived satellites of the Milky Way because of their excessively large velocities, angular momenta, and total energies. Comparing them to other MW halo population, we find that many are at first passage, $\le$2 Gyr ago, i.e., more recently than the passage of Sagittarius, $\sim$4–5 Gyr ago. We suggest that this is in agreement with the stellar populations of all dwarfs, for which we find that a small fraction of young stars cannot be excluded. We also find that dwarf radial velocities contribute too little to their kinetic energy when compared to satellite systems with motions only regulated by gravity, and some other mechanism must be at work such as ram pressure. The latter may have preferentially reduced radial velocities when dwarf progenitors entered the halo until they lost their gas. It could also explain why most dwarfs lie near their pericenter. We also discover a novel large scale structure perpendicular to the Milky Way disk, which is made by 20% of dwarfs orbiting or counter orbiting with the Sagittarius dwarf.
