The disclosure provides a system and method for synthesizing ultra-pure hydrogen from biomass waste. The present invention comprises a gasifier, an oils and tars filter, a steam generator, a water gas shift reactor (“WGS”), a heat-exchange two-phase water separator, a scrubber, a hydrogen separator, and fluid conduits in fluid communication with the various system components, which together convert hydrocarbon-based biomass, e.g., woodchips, into ultra-pure hydrogen gas. Fluid conduits connect the gasifier and the steam generator, separately, to the WGS, the WGS to the two-phase separator, the two-phase separator to the scrubber, and the scrubber to the hydrogen separator, which further comprises an outlet port through which hydrogen gas may flow free of carbon monoxide. The hydrogen may flow to a device that utilizes hydrogen to generate energy, such as a hydrogen fuel cell or to an internal combustion engine.

The present invention relates to a method for hydrogen production and to a method of hydrogen and/or carbon dioxide production from syngas. The method comprises the steps of: (i) providing a gas stream comprising hydrogen and carbon monoxide, (ii) separating at least part of hydrogen from the stream yielding a hydrogen-depleted stream, (iii) subjecting the hydrogen-depleted stream to a water-gas shift reaction, and (iv) separating hydrogen from the stream resulting from step (iii). The method according to the invention improves the conversion of carbon monoxide in the water gas shift reaction and allows to increase the hydrogen production by 10-15% and to increase the overall energy efficiency of the system by 5-7%. The invention further relates to a plant for hydrogen and/or carbon dioxide production suitable for the method of the invention.

Combining multiple subsystems involving biomass processing, biomass gasification of the processed biomass where a synthesis gas is produced then converted to hydrogen fuels or other transportation fuels for use in coupled transportation systems sized to consume all the transportation fuel produced. Carbon in the biomass is converted to CO.sub.2 in the conversion process and a portion of that CO.sub.2 is captured and sequestrated for long term storage.
