Energetic, exergetic, and environmental assessments of a biomass gasifier-based hydrogen production and liquefaction system

Abstract

In this chapter, a novel hydrogen generation and liquefaction process is presented. The source for this plant straw is chosen as biomass source. Biomass-based hydrogen generation and liquefaction plant consist of biomass gasifier, air separation unit, catalyst bed component with helium expander and liquid hydrogen storage tank sub-component. To examine the performance of plant, energy, and exergy analyses have performed. Also, the environmental analyses for various system design based on generation options have been conducted to reveal the CO2 emission of system. The energetic and exergetic efficiencies of plant for the base design parameters have been found as 68.26% and 64.72%, respectively. Parametric analysis results also indicate the effects of some variables on system performance and environmental effect of the system.
