Essentially the same process. The important part is the sequestration of carbon in the ground and the safe transportation and use of hydrogen to generate electricity. I think it depends on which process is most efficient and gets the most energy out of the hydrogen molecule with the least amount of pollutants. I think the fuel cell is supposed to be more efficient than burning hydrogen to generate heat to drive a steam turbine.

Not as efficient and very dirty. Does not help with the main problem of carbon release into the atmosphere. If you don't give a #### about the environment or solving the climate change challenge, then this is the solution for you! If you are trying to sequester carbon where it already is, while extracting the fuel we need, this is not a good idea. The intent of the proposed process is to extract hydrogen from the bitumen while leaving the nasty byproducts in the ground where they are. It's carbon capture without having to do the carbon capture after the fact.
