The hydrogen is needed for making fuel, but why would it be needed for sequestering?

  The carbon is sequestered by turning it into fuel.

    No, the carbon is sequestered buy pumping it deep underground. There's no reason to make fuel if you don't plan on burning it.

      That's what you do when you sequester it with calcium oxide. This article is about using carbon dioxide to produce usable fuel, that you would burn. Scaled up it would provide a carbon-neutral solution to long-term energy storage.

        The article also mentions sequestering underground, there's just no way to make a profit doing so at the moment.
