We don't necessarily need to recreate the bonds to sequester CO2. My understanding is that CO2 can be pumped underground in locations that used to hold natural gas. It does take lots of energy to pull the 400 ppm of CO2 out of the air. It is possible there are better sequestration methods than direct capture from the air. If want to make green fuel from the CO2, that takes the same amount of energy as the fuel contains. Using green fuel in existing cars, trucks, and trains won't work. It only makes sense for things like shipping or airplanes that go long distances. And other fuels like hydrogen, methane, or methanol that are easier to produce might work for those.
