"This giant bubble on the island of Sardinia holds 2,000 tonnes of carbon dioxide. But the gas wasn’t captured from factory emissions, nor was it pulled from the air. It came from a gas supplier… “The facility compresses and expands CO2 daily in its closed system, turning a turbine that generates 200 megawatt-hours of electricity, or 20 MW over 10 hours.”
more greenwashing from the fossil fuels industry
But fossil fuel companies don’t want energy storage, right?
sure they do, why do you think they’re buying lithium mines? they love mining resources because it encourages the “infinite growth” feedback loop to keep going
Thats not what this is regardless of what you’d personally like it to be. You’re showing clearly that you’re poorly educated on electricity generation.
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
What’s your plan that doesn’t utilize the existing fossil fuel industry at all to go cold turkey on oil and full throttle on renewable?
subsidize energy storage solutions that aren’t as economically profitable as fossil fuels. like thermal batteries, pumped hydro, etc.
most people don’t need that much energy during the night, so that is a red herring from the energy companies. the reason why we need this much storage in the first place is because of the infinite growth mindset instead of making industrialists pay for their own shit when they’re consuming energy in a race to the bottom. if we banned all the slop products from being made, energy demand would go down exponentially.
in a worst case scenario, we could 100% only rely on renewables and deal with the fact that we’ll have power outages during sleeping hours. that pill would be much easier to swallow if everyone is sharing the same burden, like during the lockdowns. and for the disabled people that need electricity to stay alive, give them refurbished EV batteries for free, there’s already more of them on the market than we could use in a lifetime. same thing for hospitals and essential institutions
deal with the fact that we’ll have power outages during sleeping hours.
let me guess, you live somewhere winter doesn’t exist.
couldn’t be more wrong, also we have this thing called insulation and water tanks. we already use water loop radiators here, there’s nothing stopping us from preheating the water to last us through the night. also, wear more layers instead of being a wussy
Unless I’m mistaken, hydronic systems like those USUALLY require a pump to circulate the water.
It came from a gas supplier…
Where do you think supplier got it from?
Also: WHERE ARE THE ROUNDTRIP EFFICIENCY NUMBERS???
This CO2 is acting as a reusable fluid in a closed loop. The initial capture of the CO2 costs energy, but the battery keeps using the same CO2 over and over again. So the question of efficiency should be more about land usage and maintenance of the rest of the parts and the labor needed for each megawatt stored vs what other grid scale energy storage costs in materials and labor.
The rough reality is that batteries aren’t going to be up to the task of grid scale energy storage unless they have a couple huge breakthroughs. Something like this is a far less materially expensive way to store energy for later use.
Currently most grid scale energy storage is just pumping water up a hill and letting it back down through a generator. It is extremely limited in where it can be used and requires tremendous space to be effective.
This concept was started 3-5 years ago, when retail batteries where $500/kwh. They are now under $100/kwh. Concept is worthwhile for diversification of resources and talent.
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?
They are talking hectares in this and it looks like the power density is below that of batteries, but its also cheaper per MWh.
A home long term battery makes a lot of sense, I have thought for a while something that goes from water and the air into methane or even liquid fuel would be highly beneficial as it could run from a generators through the winter and act for long term storage without requiring a turbine.
