Life cycle analysis of processes for hydrogen production

Production of Hydrogen by Steam Methane Reformation Process

“…A new era of clean energy is emerging nowadays, in which hydrogen plays a prominent role [19][20][21][22][23][24][25]. The environmental effect of hydrogen production can be assessed through a life cycle of system used presented by Smitkova [26]. Hydrogen is not freely available in atmosphere but can be extracted/produced using several systems.…”

Life cycle assessment of hydrogen production from underground coal gasification

“…They concluded that H 2 production from SMR-CCS led to 67% lower GHG emissions than conventional SMR. Aspen Plus software was used to conduct a simulation of large-scale H 2 production from water splitting thermo-chemical cycle and the obtained results were then used to implement the LCA in [32]. Furthermore, an exergetic LCA of H 2 production from wind and solar energy showed that although the use of wind and energy has lower fossil and mineral consumption, the cost of H 2 production is 2.25-5.25 times higher than SMR-based H 2 production [9].…”

Mathematical modeling and environmental analysis of heat pumps integrated in aprocess to treat spent pickling liquors

“…Life cycle analysis is the assessment of the environmental impact of a given product or service throughout its lifespan (Smitkova et al, 2011). All energy, material, and waste flows released into the environment are evaluated and accounted (Brown et al, 2001).…”
