Carbon capture is 100% useless until the day that we completely stop using carbon energy sources.
Even if you use solar panels, that energy would better be used directly.
It's not useless. Carbon capture will have to become mandatory at industries that will still require fossile fuels for a little longer after electrifying everything. Think cement and steel production. This is called on-site carbon capture and prevents releasing more carbon to the atmosphere. This is already happening.
Now that stupid thing that sucks C02 gas out of the air, yes, it's total bollocka and will never ever work efficiently. Maybe if we eventually develop cheap fusion power.
But that isn't how technology works. We'll need carbon capture to be at a point where we can actively remove carbon from the atmosphere at a higher rate than it enters the atmosphere as we ween off carbon fuels if we ever want to survive climate change long term.
We will almost certainly need to remove carbon already in the atmosphere. Yes, we can wish getting serious about climate change one or two decades ago would have made that unnecessary, but we're stuck with this choice now. Short of replacing every single carbon producing device tomorrow, that's where we're at.
Yes we are and because of those choices back then, we are fucked. The next generations will be fucked worse with each generation. It will take centuries to clean this shit up if we actively work on it and spend over 50% of our energy budget on cleaning. If we do nothing it might never recover and be the end of us...
There is a lot of things wrong with your statement but first and foremost is that Carbon Neutral is no longer a solution for our problems. Without a way to alleviate and regulate emissions already in the atmosphere the Human Race is still on a death march if it stopped producing today, much moreso 30 years from today. In addition to that, the sale of power to consumers can just increase consumption, and the infrastructure to move power and store power where it is needed is not necessarily there so for example Iceland's Geothermal powered Carbfix may not be efficient on paper compared to magically selling the power off to a far off place: it is still an optimal nearly lossless solution given their circumstances.
No, my statement is perfect correct.
Starting carbon capture while there is still fossil fuel power generation is stupid at best. If you do it for research, sure, go nuts. Anything beyond is just making shit worse.
If you have the energy and no where to get it to, that might be the one exception, perhaps but that's it.
If you do carbon capture with energy from CO2 power then you're literally making it worse trying to make it better. If you use non CO2 power you're still doing it wrong because of losses, that power would be better used to avoid others using CO2, you'd be more energy efficient that way.
My point is that there are multiple companies currently doing carbon capture and its just stupid, its another one of those "look at me being smart! Pay me money!" schemes that want government money that would be better spent on replacing CO2 power sources instead.
The "one exception" just described the vast majority of the operations. There is no using the power to avoid using CO2 because that's not how the power market works at all. If prices go down, consumption goes up. If you think some Carbon Capture facilities are a net zero effect aside from collecting data then that's fine, if you think they're a dumb thing to be spending resources on then that is fine, but you're absolutely not correct to say it's more efficient to put all that energy into a giant capitalist grid.
I'm not saying that at all, I'm saying that it's literally throwing a bucket of water on the floor and then mopping it up. Better not throw the bucket on the floor to begin with
Okay well the reality is people have been throwing water on the floor for 20 years and you don't want us to clean it up.
No.
People have been throwing water on the floor for 200 years now, since the start of the industrial revolution, and right now a huge hose is connected to an enormous water tap and that hose dumps all the water straight on the floor.
You want to take a mop on that, I say that the mop is make ng it worse, because I need you to help me get rid of that hose.
Once the hose is gone, please by all means, mop away, we will need it, I fully agree. But while that hose is dumping water, I need you ) that is, the entire world) to first focus on stopping the water flow.
Edit: and just so you understand the severity of the situation: even if we spend 5-70% of the worlds energy budget on mopping 24/7, we'll likely be mopping for the next CENTURIES to get rid of all the extra CO2 we dumped for the past 200 years.
