Life cycle analysis, performed in compliance with ISO 14040 showed the best environmental performance for the production of 1 m2 of RH and coffee chaff panels.
Such conditions ensure not only the lowest consumption of energy to generate a given amount of hydrogen but also the best environmental performance of the entire system.
Particularly given a set point temperature of 0 °C and a leakage rate of 10%, R-410A determines the best environmental performance.
Among the coal fired options, Integrated Gasification Combined Cycle (IGCC) systems have the best environmental performance and are potentially suitable candidates.
Within the selected framework and assumptions, the results show that the source-separation system had the best environmental performance in terms of direct water use and the lifecycle impact categories.
In case of rolling mill reheating furnace, a design for the minimum mass flow rate and bypass of any exceeding fluctuation appeared the most economical solution, whereas the best environmental performance was achieved for lower bypass of the heat source.
Regarding the compressed SNG systems, the straw-based system results in the best environmental performance.
To investigate the impact of coefficients on the selection of the alternative with best environmental performance, we conducted the sensitivity analysis.
