The present invention discloses a fluidized bed system for the single step reforming technology for the production of hydrogen. Single step reforming combines the steam methane reforming, water gas shift, and carbon dioxide removal in a single step process of hydrogen generation. In the present invention, to address the heat transfer and the replenishment issues associated with single step reforming, the sorbent particles are fluidized. This fluidization allows the sorbent particles to be regenerated and consequently allows the optimal operating conditions for single step reforming to be maintained.
