I suggest reneweconomy.com.au
Former business editor at one of Australia’s large newspapers who has brought his lens to the energy transition. Lots of high quality contributions.

Nissan Leaf was the car I wanted but with the passively cooled / warmed battery I didn’t. Good to see they have got over their original design error. The cells are good. I use salvaged originals in an electric maxi scooter. ~15 years from manufacture but capacity degraded b/c no thermal management.

All our food waste is processed into soil in our city. So it’s the packaging they now burn for energy. CO2 not captured. Try harder!

Agree. Might be useful for some things at the very edges, bagasse maybe but am happy to be corrected. Seeing as we can get 1440 degree heat from renewable electricity aren’t we just providing agricultural subsidies (USA corn for ICE)? Try harder.

Check out Australia. Distributed batteries plus grid scale batteries doing many jobs: extending the use of solar energy and capturing excess wind, allowing existing transmission to increase utilisation without augmentation, grid forming inverters providing essential system services. So good.

Got a favourite Sankey diagram to hand? I never get tired of that visual. And it shows the Primary Energy and energy (services) provided in such a neat way (and all the waste in between).

Electrification reduces the amount of energy we need to run an economy. By a lot. I don’t know what the last % of RE cost will be to remove all emissions but given everyone said we’d never get anywhere near where we are, year after year after … my guess is present predictions are very wrong.

So far as I understand Michael’s position, it is that flight is a human good and therefore flight remains and even expands but has to decarbonise. So, on that basis, how do we do that with any fuel the emissions of which have to be scrubbed from the atmosphere? On frequency of fly, I agree with you.

Is this geological sequestration? We have the largest underperforming (to put it politely) project tapping CO2 from the methane gas stream in Western Australia. Direct capture is the most efficient and no one seems to make it work. For aviation this would be DAC, cheaper?

Isn’t hydrogen, albeit converted to some e-fuel, in the C grade (much closer to unavoidable than uncompetitive) in your hydrogen ladder?

All inverters installed for the last couple to few years are remotely controllable to be turned down when there is over production. Rarely used. Government is providing incentives for BTM batteries which are themselves to be controllable to discharge to the grid during periods of high demand …

We have what is called an “integrated system plan” for developing the grid going forward. They are incorporating the low voltage network into their considerations and the consumer based resources that exist there. It is going to be tricky coordinating this but having had a battery for 7 years now …

Top of mind here. It would be interesting to see what happened in the old days when 1st electricity was from microgrids and we then rolled out transmission to centralise generation. Perhaps the newspapers were littered with upset but I suspect people were happy to have better access to electricity.

Someone here must have the detail of the massive public money received by nuclear over time and currently despite being a mature technology.

We are certainly grappling with the problems of grid capacity expansion (cost and siting) in Australia for our VRE build out.
comment in response to
post
One was built for us billions of years ago and harnessing its output is much cheaper and quicker than replicating it here. If we are serious about climate change we would be (and are) building firmed renewables not running coal and gas longer while we wait for expensive nuclear to arrive.
comment in response to

Would it be more like 30 years ago and now, never? 20 years ago the plant might just be coming on line and now it’s locked into a PPA way out of the market when compared with firmed renewables (merchant, it’s dead). Not everywhere yet but surely trending towards everywhere.

400kW means you are not dining in. If dining in you probably only want a 50kW charger.

Zero? Be a good day when it happens. Until then we are each adding to the problem. And adding each adds to the problem.

On this point. I have no gas, no fuel car and only buy electricity I can’t produce myself from the period of the day when renewables are in surplus. A good start. I don’t eat animals which makes an even bigger impact. The biggest impact by far was not having any children. Choices ... consequences.

WA does not have choice of retailer (bad), but it has the best balance of time of use tariffs meaning that I charge my car, heat my water etc and charge my battery for no more than 8c/kWh (some offset by my 15 year old solar panels). When the sun goes down it’s still providing me with solar power …

Measurements can tell a story but I first went to Paris as an adult 15 years ago and last a couple of weeks ago and pollution in Paris is dramatically reduced making it an ever more liveable city. I mostly skipped the metro and took the bike.

Southern States will appreciate the diversion of extra wind capacity and the lower consequent electricity prices attracting more industry to their territory.

An excellent decision. Wind farm developers and the industry looking for cheap electricity can flock from Queensland.

… that would suit me as I have a battery and my draw during the peak period is zero. My maximum draw is during the super off peak period, which is what the grid operators want. There is more value to be obtained / shared with the benefit of a battery, including at EV fast chargers.
comment in response to

That sounds right. Based on the notion that they have to have it available for any time in that month so you pay for it to be there. I have seen tariffs that attribute the demand tariff only to peak periods which makes more sense. That is, you pay for highest demand in a peak period…

For sure. I am unclear as to how it works out financially. In Australia flat rate electricity is around 32c (although my TOU tariff ranges from 8 to 52c, guess when I charge) and fast charging ranges from 48c to 69c depending on time of use….

Slightly lower than France fast charging. But with standard flat domestic tariffs at €0.17c in France, is €0.49 losing money at the fast charger?

… Alternatively all the home use data is available for anyone with a battery. I can see exactly what I have used at home for the 7 yrs I’ve had one. Here in Perth, everything builds for summer but I only have a minor uptick in winter from the spring / autumn troughs.

Much as we care about fossil pollution generally, cutting out local pollution which is often produced by small engines not meeting large fossil engine standards is an even bigger win for electrification of transport. Thanks for sharing.

I see this a lot with any LLM I use. It is very handy for things you already know (and want to confirm) or are prepared to spend the time working out whether it is right or wrong. What I really want to to know is what is the exact reliable use case. I pay for it, which I am happy to do.
