To compare the performance in natural resource utilization<br /> for different hydrogen production systems, in this paper, two laboratorial hydrogen production<br /> systems from biomass and one industrial hydrogen production system from natural gas are analyzed<br /> by using industrial emergy evaluation indices. http://en.fcc.gov.ir/article25.aspx
