Hydrogen production by flue gas through sulfur–iodine thermochemical process: Economic and energy evaluation

Hydrogen Production by Solar Thermochemical Water-Splitting Cycle via a Beam Down Concentrator

“…As a downfall, the environment is, however, corrosive on the reactor side, and the supply of high-temperature solar heat is also challenging. This cycle has been extensively studied (Norman et al, 1982;Anzieu et al, 2006;Vitart et al, 2006;Zhou et al, 2007;Cerri et al, 2010;Zhang et al, 2010;Liberatore et al, 2012;Park et al, 2019), with technological advances still needed. Opposite to direct solar thermochemical water splitting into an integrated receiver/reactor (Chueh et al, 2010) presently featuring a very low TRL, the TRL of the indirect solar thermochemical hydrogen production is medium.…”

Heat exchanger application for environmental problem-reducing in flare systems of an oil refinery and a petrochemical plant: Two case studies

“…Abdulrahman et al [13] investigated the improvement in Egypt's oil and gas industry by implementation of flare gas recovery. Some studies have been conducted on CO 2 capturing [14][15][16][17] and hydrogen production [18][19][20] by using flue gas as a source in order to save fuel consumption and reduce pollution emissions from furnaces.…”

Hydrogen production via thermochemical water splitting

“…Further laboratory-to bench-scale demonstration studies were carried out by JAEA in Japan (Kubo et al, 2004), ENEA in Italy (Parisi et al, 2011) and CEA, Sandia NL, and General Atomics in a common project in San Diego, United States (Russ, 2009). Researchers at ENEA, Italy suggested a modified S-I process based on the use of SO 2 from other sources, forming a so-called open S-I cycle (Liberatore et al, 2012). Sulfur dioxide-containing flue gases stemming from the combustion of sulfurcontaining fuels represent the sulfur source of this cycle.…”
