And as such, the experts should be answering questions related to voltage, frequency, and rotor angle stability. Sub-transient & transient analysis, and system resiliency due to small and large disturbances, should be at the forefront of renewable energy discussions as we continue increasing the penetration of inverter-based resources while losing the rotational kinetic coupling of conventional rotating machines, such as synchronous generators. While I agree the two largest physical constraints are energy storage and power flow limitation issues, we need to seriously start committing resources and investments to understanding and improving the conventional protection mechanisms and control algorithms on the grid today. Directional power flow relays must be updated for distributed generation, the increasing nature of voltage harmonics due to non-linearities and their effects on equipment, the list is seemingly endless. If we aren't careful, we will compromise the integrity of the grid, which would lead to blackouts, even with the necessary infrastructure investments in generation, transmission, and storage.

Dave and Rosie should collaborate, that would be quite a YT episode. Maybe on the materials required for wind turbines, innovations in maintaining off shore blades, or potential pros and cons of different micro scale 'at home' or 'in backyard' wind energy systems.

Having lapped the map several times in Australia and taken extensive road trips in the US, all the while observing energy and lifestyle trends, I have a couple of observations. Some of the most desirable areas to live only lack water and previously lacked energy. Those places in the US are actually populated because of water from the Colorado River. Energy is no longer a problem wherever there is wind and sun. Wherever there is cheap energy and sea water, potable water is no longer an issue. The Southern and Western coastlines are now ripe for great living, where previously water from the Murray River was available only as far West as Ceduna. Eucla, Esperance, Kalbarri, Denham, Exmouth etc are all great lifestyle choices. Most of these locations are at the pointy end of the renewables spear. Local water infrastructure that enables population in remote locations is more economical than bulk energy transmission from remote to populated areas. As Rosie points out Australia has the box seat regarding renewables. Having thought about it for years, I could go for days about the economical opportunities.

Hello Rosie, Thank you for mentioning the term "Dunkelflaute" (greetings from Germany!). I would like to point out a few local or regional storage systems: 1) RedoxFlow - a liquid-based storage system, where a lot of research is already being done on different chemical element combinations in terms of efficiency, toxicity and costs. What I particularly like about it is the scalability - the converter unit is decoupled from the storage. You increase the amount of storage simply by adding more tanks! In addition, it is a closed system that does not experience any (or hardly any) degradation - unlike e.g. Li-Ion batteries. 2) Seasonal ice storage. I haven't delved deeper into this matter yet, but here in Germany a number of systems for larger houses and house complexes have already been installed. 3) Here in Germany there are already municipalities where all renewable electricity producers are actually brought together and stored in a specially constructed 40-foot container on the outskirts of the village. In the evening and at night, the electricity is made available again. The regional power company supports this project because it saves them having to upgrade the power lines to this location. And the place's fluctuating electricity draw is compensated for pretty well.

Thanks for the video, Rosie. Nice to see you on The Fully Charged show and your channel.

THANKS for letting the experts speak directly! Rare in the media ;)

Excellent presentation of where Australia is up to in the transition to renewable energy.

In the meantime cost has gone to the roof.

Wow so dense with information. Here's my notes i took, i hope they're useful to others too: in 2021 Australia got 29% of it's energy from renewable sources. In the last 12 months (as of end of Feb) we got 35% from renewables. 13% was from wind, 9% from rooftop solar, 6% from utility-scale solar farms, 8% from hydro. Rooftop solar is currently at 28 GW total capacity (1 in 3 households have solar panels). We're expecting rooftop solar to triple by 2030 (7yrs). Utility-scale wind & solar is currently at 17 GW total capacity that gives us 21% of our energy. We have another 17 GW worth of projects paid-for & ready to build. So that's about 2/3rds of our energy from wind & solar by 2030 without changing anything. Energy Market expects/projects that renewables will be 83% of our energy by 2030, and 98% by 2050; By 2050 2/3rds of households will have rooftop solar with 5x the current combined capacity (i guess ppl will have more panels, but also there's more households); Utility wind&solar will increase by 9x to 153 GW. During last 12 months the minimum from renewables was 1.6% on a windless winter evening & the maximum was 66% at noon on a spring day. If we tripled our current renewables we'd generate day by day between 5% - 200% of our energy from renewables (depending on wind & sun strength). Studies suggest Australia needs between 300-650 GWh of storage with a power output of 15-50 GW. This is less than 1 day's worth of energy storage for the nation. In Australia we don't have long periods with no solar or wind, & basically never across the whole country. Australia currently produces half the world's Lithium, and has the 2nd largest reserves of Cobalt. The mining sector makes up 10% of all of Australia's energy consumption. If wind & solar continues being installed at the current rate we'll triple our current variable-renewable capacity by 2030. Coal still makes up over half of our electricity generation. 30% of Australian existing coal-fired generation capacity will close down by 2030 (just based on announcements so far) but it's projected to actually be 2/3rds by that time.

I enjoyed Rosie’s presentation as always. I am 99% off-grid with solar and home batteries. To get to 100% I did consider wind as it tends to be more windy in the monsoon season here, but having seen Rosie’s excellent videos on domestic wind I decided to not go down that route. Instead my next EV will have V2L, maybe the BYD Seal which has 4kW power output. We hear a lot about V2G but very few cars have this built in. I would like to see a show about V2L which is easy to integrate into a solar inverter. As I have a big solar system I am banned from exporting to the grid, this is the case in many countries and people are restricted to smaller 5kW solar systems. This restricts how much domestic solar can be part of the solution.

Then you have the liquid metal batteries based on Sb and Ca and recently Al and S. You have the redox batteries based on V or Fe. Coming along are Na batteries. All have some huge positive characteristics not found in Li batteries besides the easy access and cheapness of the elements they use. All can be cycled between 0 and 100% charge with no damage, last much longer than Li batteries, use simpler electronics for their charge and discharge cycle and are much easier recycled, if you ever need to recycle them. How about an in-depth treatment of each of the alternate battery chemistries. I bet all they need is market share to out-compete Li batteries for cost.

Commercial buildings are the same but the incentive is greatly reduced running costs which is better recognised in building design. This is a well developed industry because the associated running costs savings are significant in larger buildings. There was even a nation wide government incentive about 12 years ago to pay for people to insulate their homes.

Wind turbines, if you build the pylons correctly, the will outlive the generation units/ blades and can have new units installed with the latest, more efficient technology (already being done in Spain, and no doubt elsewhere) Generator? Recyclability must be "high 90's"? . Blades? Watched a video recently detailing plans to recover 98% of material (now there's enough to spool up the industry!) As I recall (just for instance) "fibrous material" in the blade, once shredded, makes a great filler for cement, offsetting carbon in that production process. ...... Solar? 95%+ Glass and Aluminium, that'll be fully recyclable. Copper? Same, the rest are trace elements, most of which will be recovered in the glass recycling process. . We should of course note that the "lifetime" of a solar panel (similarly to batteries) is calculated at "±80% of original capacity" with a guarantee on the latest units of at least 20 years, so they remain useful for way past that time. Balanced against the high carbon construction and constant daily footprint of other generation, it's not even close.

The blades are being cut into three in some states in America and buried in landfill. We've been sent photos of stacks of them that were dumped near a national park in Queensland. Victoria is the only state that I know of to declare solar panels as E-waste so instead of paying collection agencies to pick them up it's cheaper to send them to landfill. The collection agencies strip off the frames and wiring and call that recycling. The bare panels are stockpiled. And don't think that they are "mainly glass" for one thing there is much more to them than that and it isn't easy to separate out the different materials. There are also different types of solar panels. We have a commercial solar utility 4 kilometres from our home that is 87MW of thin film cadmium/tellurium solar panels. These panels are highly toxic and they need to be recycled in special processes including acid baths and use of other chemicals. The nearest facility to recycle these panels is Malaysia. This solar facility has not done well and is on to its third owner, how confident should we be that these panels will be properly recycled?

Well.... It's not free per se as there would be some associated cost but I think the point you are making is that the excess would otherwise be totally wasted. At the very least (from the start) grid level energy storage would reduce and eventually negate the need for very expensive peaker plants. It really is a no brainer.

I am a big sceptic on all this. However I did a quick estimate of how much just the battery storage for Australia might cost. I take (from the video here) what is likely a minimum viable amount of 50GWH storage. All the numbers here are in USD (including Australia's GDP). Tesla Megapacks are $2 million (including installation) and store 3.9MWH. So you would need 256 of them to get 1GWH of storage and (256 * 50) = 12,800 to get 50GWH of storage. Total cost would therefore be around (12,800 * 2,000,000) = 25,600,000,000. Plus shipping, land purchase, maintenance etc. So we are looking at a 30 billion project. Which is not really such a big deal in a country which has a GDP of 1,552 Billion. Still I am sceptical. Why? Because I have yet to see even a sniff of a coherent plan, with reasonable estimates and timeframes. In the current hysterical over-reacting polity I predict that mad government directives will be implemented with maximum incompetence that will crash the economy and either turn the voters off the whole idea, or render any such plan moot by reason of national poverty.

One thing I notice about Rosie Barnes is that she never talks about economics and costs. She talks about solar and wind replacing coal because they are renewable, not because they make economics sense. At the very end of this video (12:35) she says of coal plants, "No one is forcing them to close, or paying them to close. It's not happening because of government policies. It's simple economics. Adding more renewables is now cheaper than continuing to run existing coal plants." But the headline of the news article she shows at 12:15 says, "Australia hastens coal plant closures to catch up on climate". She also doesn't mention that South Australia, with the highest percentage of solar and wind, has the HIGHEST electric rates in Australia. The costs for solar and wind installations frequently "forget" to mention that they don't include the costs of batteries, back-up fossil fuel generating plants (usually forced to idle at an economic loss in order to provide dispatchable electricity during dunkelflaute), or the additional transmission lines that conveniently-located fossil plants don't need.

Absolutely what I was thinking. Well said. We will defeat these brainwashed people who refuse to look at the facts.

Woo Rosie made it to the fully charged show! Glad to see another true professional in the show

Hawaii just shut down their last coal power plant. They are another power island like Australia so hopefully the two will share their experience as they both become 100% renewable.

If 100% renewable = 100% broke, I think I'll go with Nuclear.

Hawaii ended new net metering contracts in 2015. Electricity is very expensive there and they have abundant sunshine. Grid defection there is a big problem for the electric utilities in Hawaii. Homeowners are trending toward 100% renewable which leaves the utilities with a customer base of renters and businesses. I think the utilities will learn from the homeowners that solar is the way to go, and that buying and importing hydrocarbons from the mainland is a dead end.

If you're exploring alternative energy sources in Australia, can you do a deep dive on wave power, tidal power, or sand batteries?

Australia is also a major supplier of uranium, which could be used to power reactors like Molten Salt plants that would not need any battery storage at all. With the Moltex design the power plant can also produce power on demand even with highly intermittent solar/wind on the same grid so the reactor using stored heat in salt could act as the only battery needed. So a 2GW thermal plant you would have 1GWe avg output, but with 2GWe generators those could be ramped up and down to counter match the solar/wind. This matching variable nuclear with variable renewable is a good match.

That's a terrible idea. Who wants an industrial heat source that doesn't just make electricity but has direct industrial heat and synthetic fuel applications? We want an electricity-only source that needs 100% backup, is weather, time of day, season, geographic, and material resource dependent. Each of these dependencies makes the energy far more expensive and less reliable but creates green jobs. Sure the waste can be reused to make more energy but until then it will frighten people. Sure it can't hurt anyone but think about their feelings.

Australia can provide solar for the whole world. Easier than Sahara. Since it's one country. Easy admin

Yay Rosie!

Fantastic video thank you!!!!

Rosie says that to get to 100% renewables isn't much more than we are doing now, then goes on to say it is 3x current production just to get to 100% of existing electricity demand. Australia total energy consumption in 2021 = 1,589TWh Total electricity production in 2021 = 247.06TWh So it's closer to 6 or 7x current renewable production to get to 100% renewables for our entire economy.

What use is being made of the electrical connectivity from closed coal fired power stations? e.g. placing wind and solar generation at the closed sites.

Great video and overview, i think the govt should place more emphasis on home battery storage, Could do something like applying the same STC structure to battery purchases. That way as mentioned we are generating and using our own green energy within our own homes (taking pressure off the grid). The current STC scheme has made roof top solar the power house it is today, should batteries be the next natural extension of such a successful program?

Storage is only needed in local areas it is cheaper and better to have an "oversupply" of green electricity and heat generation! That way we have enough for our domestic needs and the extra can be turned into ammonia and hydrogen for export. Then if still have some spare we can desalinate seawater and pump it over the range to keep our rivers flowing. Inland there are huge amounts of underground water that is salty and we could desalinate that and wouldn't need to pump it so far to use it for irrigation.

Great to have Rosie Barnes as part of the Fully Charged Team. It seems for some time I have not heard any reference to wave or tidal as possible intermittent renewable options. Have they fallen out of favour?

I'd love an up to date episode on battery technology. There seems to be so much going on there it's difficult to keep up.

Australia has not built a coal fired power plant since 2009 & there is one new gas generator sched6to be completed in 2024 which is designed to run on hydrogen when it becomes available in quantity. There have been many proposals for coal fired plants in QLD near the Great Barrier Reef but none have been successful in gaining involvement or approval.

That was really focused on the energy in the power grid, but there is also energy for transportation, cars, boats, airplanes, etc.

Great video Rosie! Suggested storage methods Sand / Heat Compressed air Also for generation Wave wind seems promising on king island from company wave swell.

Just get it done. Shame windy / tidal UK isn't doing better but everyone might be spurred on a little if Australia does an overwhelming job.

Tidal should be a bigger area of focus because of its regularity and the energy density, but the ocean (and especially the Southern Ocean) is an unforgiving environment. Australia has such a large landmass that its shouldn't really need to do anything offshore, so perhaps Australia will never be a leader in Tidal power?

In 2021 Australian electricity was 71% fossil fuels, mostly coal which is the most polluting type. In 2021 UK was 42% fossil fuels with coal only 2%. The UK doesn't have much space available on land for renewables, unlike Australia, and yet are doing pretty well with electricity actually. The big problem will be home heating which is mostly gas. We need to get every house in the country insulated and a heat pump installed. This should have been started a decade ago or more. But unfortunately because it is difficult the government is putting off getting serious about it, by pretending we can burn Hydrogen in boilers instead, which is stupid. It would cost about 8 times as much to heat a house with green Hydrogen compared to a heat pump.
