DYNAMIC BEHAVIOUR OF A NOVEL SMALL-SCALE HYDROGEN REFORMER

This paper explores dynamics for control design for a novel small-scale hydrogen reformer based on compacted plated heat exchanger technology. Reforming is seen as an important step towards the use of renewable fuels as feedstock. For reforming to be competitive to electrolysis and trucked-in hydrogen, high operability and robustness is required. This is achieved through an understanding of the system dynamics and robust control structure design. The paper identifies important dynamic features of the reformer unit and focuses on the responses in the hydrogen production rate to changes in several candidate inputs. This work was part of EC project Hydrofueler.
