The closest we have are emissions reductions on power generation and other highly polluting facilities. Carbon capture of CO2 from the atmosphere is not being used successfully, anywhere. There are plenty of feel good articles about trials and test sites and experimental facilities, none of which are within multiple orders of magnitude of being capable of scaled out to the amounts needed. They all require such vast amounts of electricity that it would be better using that electricity to not emit the carbon in the first place. There are no technologies on the horizon that could even put a dent in our current yearly emissions, let alone clean up past excess. Yet it is used time and time again to sell carbon neutral plans and policies to the public, which will never reach their targets.
Saying CCS isn’t currently successful is like saying utility grade solar wasn’t successful in the 70s. We’re on the start of an exponential curve and the tech will only get better.
I don’t understand why people think this is “used” to sell carbon neutral plans: why wouldn’t you count carbon sequestered using CCS? It’s no different to assuming batteries will get a lot cheaper: it’s not a certainty but it’s heading in the right direction.
Let’s put it this way: if we could use CCS to produce carbon neutral power from natural gas, would you reflexively oppose it? Or would you be thankful that we now have another carbon neutral power source?
I separate emissions reductions tech, such as fitted to power stations, from atmospheric carbon capture. Filtering emissions at source makes sense, and is nothing new. Lets do more of that and better, and I will have no problem with carbon neutral natural gas power if someone can get that to work. Trying to suck carbon out of the atmosphere though is a fools errand, and I do reflexively oppose that, because it has always been lies and propaganda. Large chunks of climate policy assume magic will happen, because technology will save us. But math and physics disagree.
What’s the maths and physics that make it impossible?
I’m not saying you’re wrong, but I’m interested in the limits.
I still think reflexively opposing a potential solution is stupid. Skepticism is healthy, automatic rejection is a waste. I wholeheartedly agree politicians spout a lot of nonsense, and that the solutions are closer than we think, we just need to get the bad policy out of the way.
