I guess it comes down to whether we want to primarily communicate battery size in terms of charge (Coulombs = Amps * Time) or energy (Joules = Watts * Time).

The first metric you multiply by your operating voltage to get the second metric, whereas the second metric you have to divide by your voltage to get the first. Depends on what comes easier to most people.

That’s an amazing idea. I had no clue this was a thing. I would imagine openvpn is free?

Game is super fun to watch on Twitch. I’m hoping more of my content creators pick it up and play it. I’ll support it

Yep exactly

I agree: transportation will probably favor hydrogen over batteries.

That being said, to pile on hydrogen, I’m not sure if I like the water demand part of it either. Coastal hydrogen production might make sense if sea water is the feedstock and corrosion/discharge can be released to the source in a manner that doesn’t lead to biodiversity death.

Then again, fossil fuel and mineral based (thermal) energy sources like coal, nat gas, oil, and nuclear all require cold water for cooling purposes. If we transition those sources to hydrogen production (and maybe use in the case of 100% hydrogen fired CCGTs that GE, Siemens, andbMitsubishi are making), there might actually be increased water demand since you have hydrogen + cooling.

It’ll have it’s niche, that’s for sure. But I wouldn’t count it out.

And on the topic of better solutions, I’d love to see vertical underground pumped hydro storage pick up steam (buh dum tss). I don’t see how underground pumped hydro isn’t feasible since we already do geothermal in the same way.

Don’t store it in diatomic form. Ammonia is the common alternative for hydrogen storage and transport, iirc

And even if round trip efficiency is poor, if renewables are in excess, it would be so much better to dump that energy into something that to have to curtail.

In a region like Finland, sand batteries appear to be worthwhile for seasonal storage. Might be an avenue to pursue

Then there’s always green hydrogen as well

Hey nice to have ya!

Friendly reminder that the Fediverse is awesome, and you have the power to control the content in your feed not only by which subs you subscribe to or instances you make an account on, but also which you can block - including specific users if it comes to that. Of course, instance admins can do the same, and if that happens to content you want to see, you can always make a new account on a different instance and see everything.

It takes a little to understand the Fediverse structure, but imo it’s one of the best ways social media can be structured.

There have been steady and iterative advancements.

Steady imo is a synonym for constant, and revolutionary breakthroughs can be subjective if referring to industry or academia.

When was OP involved in this conversation?

Apologies. I sometimes refer to an OP as the Original Poster of a thread in a given post, but perhaps a better use of language would be OC for Original Commentator.

Depends on how you define “constant”. Battery prices have been falling year over year, no thanks to technological improvements.

If we’re referring explicitly to Academia and R&D, then OP is correct. You’re main point is that these huge breakthroughs haven’t affected the market, but OP isn’t arguing that.

You’re both talking past each other.

Michael Thackeray filed a patent under Argonne National Laboratory for the leading EV battery chemistry worldwide today, Lithium Nickel-Manganese-Cobalt Oxide (NMC), sometime around 2007-2008.

The first cars with that specific technology started coming out in the US market in 2013/2014 IIRC, with EVs coming out before then basing their battery chemistry on NCA (Tesla) or LMO (Nissan Leaf & Chevy Volt).

That’s a 5-7 year timeframe from laboratory to mass production.

If you consider new technologies today like Samsung’s battery in this article, and make the not so unrealistic leap that we’re better at battery production today than in 2013/2014, it’s very possible that we see this technology hit the market in 5 years or less.

Technology always improves. It’s CAPEX that hinders it, and I’m willing to bet that there are financial interests out there to keep the main battery chemistry NMC and secure steady profits.

Just wanted to say that I appreciate the nuanced debate here, and that neither of you resulted in insulting each other after getting to the bottom of it. More of this on Lemmy!
