I wonder where the crossover point is ?

It is very much country specific as it depends on the amount of renewables (or Nuclear) used for power generation.

Somewhere like Norway the crossover point is as little as 20,000kms whilst in the US or some parts of Europe it would be double this at more like 40,000kms.

If using the global average energy mix, then it is between 60,000kms to 80,000kms and depends on where the EV and ICE was manufactured.

China which currently has a much higher use of coal can be over 100,000kms. This will change as China is investing more than any other country in renewables.

As the reliance on fossil fuels for power generation drops, the crossover point also comes down.

A big reduction will be when the mandates in Europe to recycle EV batteries starts to kick in to full effect. This will bring total emissions to manufacture a new EV similar to that of an ICE, bringing down the crossover point even sooner.

Both the ICE and the coal powered steam turbine can run at optimum speed/load for the power needed.

And that Audi 'hybrid' in the Dakar a couple of years ago.

didn't mazda recently bring out a hybrid with a wankel rotary engine? The reason being that it could run on a very specific RPM where the rotary would be efficient and also very compact. I like that kinda tech :)

Hi,
Check out Edison electric log trucks for pure practical logic.

Will it be solid? Can we swap for these??[bigrolf] Are almost all existing Fast (???) Chargers obsolete already or shortly? [thumbsupbig]



"Samsung SDI has just presented a groundbreaking advancement in battery technology for electric cars. During SNE Battery Day 2024 in Seoul, South Korea, Samsung unveiled a new solid-state battery that could transform the electric car market, as reported by The Elec.
Range and Charging Speed

The new Samsung battery for electric cars boasts an impressive energy density of around 500 Wh/kg, twice as much as the best lithium-ion batteries based on NCM chemistry."[biggrin]

PS possibly by 2027 for $$$$$$$$$$$ or 2030 for the normal people[bawl]

Orrrr will it be irrelevant? :) I believe all points have already been made in this rather long thread but lets go by every one of them briefly:

• energy density: not even close to fuel
• range: given the same weight in batteries the I guess twice the range, but likely less since they can finally make cars lighter (which should be higher priority).
• charging speed: even faster charging requires even more bonkers infra that will most likely not be rolled out everywhere

And finally charging tech. Yes, if you want to charge even faster they will have become irrelevant. I can't imagine though that the battery tech will be so different that the current chargers can't handle them, after all you select a voltage for the battery and with so many cells you can make them close to the current tech.

I am more interested, forgive me, in the DOWNsides of solid state. Lithium was praised into the clouds but in the end it turned out it actually had downsides, go figure. 100% can be used! (but it's better if you use no more than 60% actually)

Anyway, where you DO get me excited is solid state batteries in my camper, my phone, laptop, ipad. If they really can deliver twice the power I certainly want them in there!

Fully agree with several of your points especially "Charging speed: even faster charging requires even more bonkers infra that will most likely not be rolled out everywhere"

Until 'the greenwashing types' stop assuming its wind, solar and very short duration and very very expensive battery storage and start looking at the additional electricity required we are in a bit of a echo chamber.

The promises of Solid state are big! Prove is required as is the trillions of $$$$$$$$$$$ of power IF most of the C02 free power is to be put in place.

Had a very interring chat with several Navy officers yesterday about current and near-term ship building. While we have a great company here making some lighter style ferries and ships. (Austal) our ships and submarine building has been a long-term tragic comedy of errors and significant cost blow outs.

My thoughts the Korean offer to do things we cannot in Warship construction is exactly the same in the nuclear reactor area with Korea already building ships at an amazing rate that occurs nowhere else in the world and already having the Modula heavy Constuction set up for Small Nuclear reactors. I would love to see a quote from Korea for future ships, submarines and SMR or larger nuclear power construction :)

You will get a laugh from this one!
It is about Ukrainians making a bomb from a Toyota Mirai Hydrogen cylinder.
The reference starts at 2.29 if you don't want to watch the lot which also references using Tesla batteries for drones.
