For most countries around the world, sourcing energy entirely from wind, solar, geothermal, and hydropower by 2050 would reduce their energy needs and costs, improve air quality, and help slow climate change, according to a study in Environmental Science & Technology.
To be fair you can use the captured carbon for building or for carbon rivers so its not completely useless. Just way to expensive.

Problem the second: when you do carbon capture you get CO2 gas
I’m starting to like the idea of growing forests, cutting down those forests, cooking the wood to
charcoalactivated carbon (in solar furnaces perhaps) and storing near pure solid carbon
