Is this a rare google W?
The idea behind the “CO2 battery” is simple. By compressing the gas using excess green power, it can later be depressurized to spin large turbines.
CO2 is a nice substance for this due to its relatively high temperature of fusion at modest pressures (and cheap ubiquity). I’d wondered why this wasn’t more of a thing with air, using excess energy to liquefy it, to later let the LN2 to be vaporized/expanded in a turbine and the LOX to be used in rockets or something. But deep cryogenics are more challenging.
Or maybe use excess power to electrolyze water for fuel cell use later?
But yeah, CO2 makes a lot of sense despite its relatively poorer specific heat ratio for adiabatic expansion compared to mono and diatomic gasses.
Great. So we’ll waste energy capturing and compressing a useless gas, then we’ll just release that into the atmosphere when it’s capitalistically convenient? Brilliant. Great work, Google. You’ve really gone green. /s
The co2 used is a fixed amount that resides in a closed loop and never gets released to make the battery work.
Try not to make a fool of yourself next time or you’ll damage the ideals you are fighting for.
I hoped this was going to be direct air capture. Then I realized that all the excess gasses would be valuable, and the system would oxidize faster pulling in atmosphere.

Battery facilities is the next step in green energy, and I like to see different approaches to this. That is what we need right now.
Will this turn out to be a worse option than what will be invented in 10 years? Almost 100% sure. But did it help us getting to a better place? Yes.
Fuck Google for alot of things though, but it doesnt make sense to do blind hate when they try these things.

And how do you know I haven’t? Do you have insight into my mind?
Here’s my stance: Fuck Google. When have they ever done anything for the benefit of humanity? If this turns out to do exactly what it says on the tin, I’ll be happy to eat my words, but pardon me if I don’t believe that Google is suddenly interested in clean energy.
let’s assume 100% of this CO2 was generated from fossil fuels and eventually will be released into the atmosphere.
is that any less green than grid storage batteries built from massive amounts of mined metals with an enormous CO2 footprint?
If the worst happens and the dome is punctured, 2,000 tonnes of CO2 will enter the atmosphere. That’s equivalent to the emissions of about 15 round-trip flights between New York and London on a Boeing 777. “It’s negligible compared to the emissions of a coal plant,” Spadacini says. People will also need to stay back 70 meters or more until the air clears, he says.
If anything it will create a market (and technologies) for co2 capture.
No, it’s a closed loop technoloy that doesn’t release the gas to the atmosphere…and google is not actually the company behind it but potential investors in new pilot plants.
Doesn’t seem very useless if we can use it.
The CO2 is not released into the atmosphere. That’s what the bag is for.
