Energy and exergy analysis of blue hydrogen production and conversion

In this chapter, initially, the main processes globally used to produce hydrogen from the hydrocarbon feedstock are introduced. The production processes, including main unit operations, will be described in detail, and process data will be presented. The overall energy and exergy analysis will be carried out on each production process to estimate and compare energy and exergy efficiencies. The primary source of energy and exergy loss in each production process will be determined and discussed, and then practical solutions to reduce such losses will be proposed. The carbon capture, utilization and storage process is integrated into hydrogen production processes to generate blue hydrogen.
