My neighbor is a material scientist for one of the big oil companies (his job is to explore alternative energy sources).
He has a good way of looking at it: You must simply compute "joules per retail dollar of stored energy". Doing this calculation you will find that petroleum is still the most energy dense fuel source - and most importantly that energy is in a "pre-stored" state. Solar / wind are all great in theory but to get to Apple-Apple comparison, you have to store that energy (cue bitcoin miners using trapped energy here).
Nature has done the work of 'storing' the energy in petroleum for us. We didn't need to expend additional energy (and carbon output) to mine hundreds of tons of lithium to make batteries.
Until the next breakthroughs arrive, this simple fact of "retail dollar per stored joule" will continue to be how the market operates.

Material scientist? I wonder if he knows a lot about gravity batteries

yeah, he's mentioned a few different physical batteries they've looked at: Gravity batteries, winding big springs, etc.
I think he thinks the most efficient is some type of thermal battery (ie. heat pumps) using molten salt. Basically you directly use solar/wind electricity to melt salts that are stored in well insulated under-ground containers. Then later you use heat to boil water to turn turbines.
Obviously, like everyone else, he thinks that once some type of highly dense solid state battery arrives, that will be game-changing moment.

Once dense solid state arrives or if ?
Solid-state batteries with ultra-high energy density are emerging as a promising solution for the future of energy storage. Recent breakthroughs have enabled the development of solid-state battery cells with record-breaking energy densities:
-
Chinese startup Talent New Energy has unveiled an automotive-grade all-solid-state lithium battery prototype with a single cell capacity of 120 Ah and an energy density of 720 Wh/kg[3][5]. This is twice the energy density of Nio's semi-solid-state battery cells.
-
If mass-produced, Talent's solid-state battery could enable electric vehicles to achieve a range of around 2,000 km on a single charge[3].
-
The potential gains in energy density from solid-state batteries come from enabling the use of pure lithium metal anodes, which have a much higher specific capacity compared to graphite anodes in conventional lithium-ion batteries[4].
However, challenges remain in commercializing solid-state batteries, such as:
- Achieving stable interfaces between the solid electrolyte and electrodes to prevent capacity fade[1][4]
- Improving ionic conductivity of solid electrolytes, especially at lower temperatures[2]
- Reducing manufacturing costs of this innovative technology[2]
With continued research and development, solid-state batteries with ultra-high energy density could revolutionize electric mobility by enabling much longer driving ranges with lighter, more compact battery packs[1][3][5].

John Goodenough was one of the pioneers...he was based at University at Austin, TX. (died in 2023). One of the theories of why Elon was so eager to relocate to TX also involved him being able to be close to Goodenough research team....
Goodenough had an impressive track record, he won Noble prize for inventing Lithium-ion battery. He also basically invented RAM at MIT.
We shall see if any of this pans out commercially...

When you forward to me, I can’t zap.
I suspect I wouldn’t be alive if it never existed. If it just went away, then I’d guess most of my life would change for the worse until we scaled up alternatives.

The typical response "Everything i use is electric. It wouldn't affect me much" kind of shows the current level of science education. Where does that electricity come from?

The Energy Return on Investment (EROI) of so-called renewable is atrocious, nuclear is the best EROI by far but you would still need a lot of hydrocarbons to lead to a nuclearisation of everything

The transition is difficult.
Electric systems are better but batteries still need a lot to improve. If we manage to have great batteries everything would look better. World should be investing in batteries development more.
