Power generation using hydrogen fuel with economical carbon dioxide capture

A system for power generation, the system comprising:

• a compact hydrogen generator, the compact hydrogen generator containing a quantity of a sorbent material and a reforming catalyst, wherein the compact hydrogen generator comprises a fluidized bed configured to fluidize both the reforming catalyst and the sorbent material in combination with a feed material, wherein the feed material comprises natural gas and steam, and wherein the feed material in contact with the reforming catalyst produces H2 product and carbon dioxide and the sorbent material absorbs carbon dioxide and forms a used sorbent;
• a gas/solids separator connected to the compact hydrogen generator to separate the H2 product and the used sorbent, wherein the reforming catalyst and the sorbent material are both fluidized in the bed and each of the reforming catalyst and the sorbent material has a corresponding size configured for the reforming catalyst to remain in the fluidized bed while the H2 product and used sorbent are conveyed by elutriation from the fluidized bed to the gas/solids separator;
• a calciner connected to the gas/solids separator to heat the used sorbent to desorb carbon dioxide from the used sorbent to produce regenerated sorbent;
• a recycle line to introduce at least a portion of the regenerated sorbent from the calciner to the compact hydrogen generator;
• and
• at least one power generator to receive and utilize at least a portion of the H2 product from the gas/solids separator to produce power.
