But if CCS operations leak, they can pose significant risks to water resources. That’s because pressurized CO2 stored underground can escape or propel brine trapped in the saline reservoirs typically used for permanent storage. The leaks can lead to heavy metal contamination and potentially lower pH levels, all of which can make drinking water undrinkable. This is what bothers critics of carbon capture who worry that it’s solving one problem by creating another.
Look I understand you’re trying to be positive but this doesn’t work. It’s not really viable for me to put more effort into explaining why each specific thing doesn’t work but take e.g. paper towels, well they rot. Unless you pack them up in an environment which they can’t rot in. Like a sealed mineshaft, which you could just pump co2 into. In either case you’re filling an empty coal mine with low density coal while using energy that could go to something with exponential payoffs like sustainable power infrastructure.
Protecting greenspace is good, reforestation is good and has all sorts of positive effects from stabilisation of local temperature to cleaning the air of pollutants. It is not however a solution to climate change. There is only one, and it is not burning fossil fuels. It is completely impractical to reverse the damage we have already done. We have added 0.02% of the atmosphere’s mass in co2, that is 1.E17 kg or a hundred million billion kilograms.
