It came from a gas supplier.... Where do you think supplier got it from? Also: WHERE ARE THE ROUNDTRIP EFFICIENCY NUMBERS???

Sure wish they mentioned the effeciency.

I run a consulting practice around flexibility. Been around the energy space for 15 years. Boy if I had a dollar for every time I've heard "grid scale [x] will soon be everywhere"

We had these things called [Gasometers](https://en.wikipedia.org/wiki/Gas_holder) in the UK for a long time. They expanded with the amount of gas stored in them, and they kept the pressure of the local gas supply up. A local gas reservoir, or "gas battery" if you like. These bubbles are basically the same idea but at higher pressure.

I wonder how resilient they are to big winds.

Sounds pretty good

>On the downside, Energy Dome’s facility takes up about twice as much land as a comparable capacity lithium-ion battery would. And the domes themselves, which are about the height of a sports stadium at their apex, and longer, might stand out on a landscape and draw some NIMBY pushback. This is surprisingly good! I would have figured it would have taken far more than twice the land than a Lithium battery solution.

Please let this be viable. The more renewable energy and storage, the better.

Wonder how small you can scale these and retain efficiency, at twice the footprint (but I'm guessing a lot more volume) of a lithium grid battery, will we see these replacing home batteries down the line?

I imagine that the bubble portion is light weight enough, one could put it on the roof of a data center, apartment building, strip mall, etc. That appears to be the piece that takes up the most space. Another thought. I wonder if the bubble portion could be oriented vertically, maybe inside a simple enclosure to protect it from wind.

more greenwashing from the fossil fuels industry

As per Energy Dome: > But the gas wasn’t captured from factory emissions, nor was it pulled from the air. It came from a gas supplier, and it lives permanently inside the dome’s system to serve an eco-friendly purpose these people are straight-up lying, how can CO2 be "eco-friendly" when all its industrial extraction processes involve fossil fuels as a source? notice how they didn't mention who their gas supplier is? that's because it would out them and their lies. it's impossible to buy gas turbines without ultimately funding the fossil fuel giants. also let's not ignore the environmental catastrophe that would happen if these were deployed en masse and a corruption scandal like the Beirut port explosion happened. it's also not lost on me that this technology is being deployed in poor, economically exploited areas like Sardinia and Xinjiang. there's a reason why they're not building bubbles in the middle of Rome or Beijing, because the people would revolt at this eyesore of a ticking time bomb. nobody would give a fuck if thousands of Uyhurs died in a mass asphyxiation event because people are already ignoring the genocide they're going through. it's concerning whenever Google gets excited about a new energy solution because we all know how they treat the environment around their data centers. if deployed, they'd use the hot breath bubbles to excuse their seemingly infinite energy consumption increase in order to keep the AI bubble from popping. this is carbon credits all over again, they'll use the CO2 to deploy more methane gas turbines because these would "cancel them out". edit: removed inaccurate claim about Energy Dome in Xinjiang, added context

>The CO2 is likely harvested directly from the atmosphere. What makes you think that? I just did a little googling and didn't find a source that commercial co2 comes from the air. The best case scenario I found was it being a byproduct of other processes. Although I'm doing this on my phone so maybe I missed something.

> The CO2 is in a CLOSED LOOP system meaning its not going to be leaching into the atmosphere. yeah, sure thing buddy. the CO2 will be in a closed loop until it won't. just like Fukushima and Chernobyl were supposed to be closed loop systems, until they weren't. disasters happen, no matter how much the techbro mindset insists that they're impossible. > The CO2 is likely harvested directly from the atmosphere LMAO, the audacity of telling me I don't know how electricity generation works when you don't even know how to read. they're using industrial CO2 derived from fossil fuels
