The amount of CO2 is orders of magnitude more than the amount of radioactive waste; you cannot just build “one factory in Nevada” and sequester all the carbon dioxide produced.

We need to capture about 1 trillion of tons of CO2 to return to sane levels, and then capture about 25 billion tons of CO2 annually. It looks doable.

That process absorbs CO2 from the atmosphere at low concentrations (400 ppm) onto stones coated with X-material. Later the stones are heated (using more fuel) to release CO2 at much higher concentrations (more than 75%). Then what? It is a gas. You need to bury the carbon. They suggest feeding it to greenhouses, to grow food, which re-releases it later.

Six orders of magnitude, to be precise. Nuclear fuel has 2 million times more energy per mass than any chemical fuel or storage system.
