Investigation of sustainable hydrogen production from steam biomass gasification
(2010-12-01)
Hydrogen is a by-product of the gasification process and it is environmentally friendly with respect to pollution and emission issues when it is derived from a CO2-neutral resource such as biomass. It is an energy carrier ...
Experimental investigation and analyses of continuous type hybrid photoelectrochemical hydrogen production systems
(2016-01-01)
Hydrogen is a highly versatile energy carrier that may become one of the key pillars to support the future CO2-free energy infrastructure. When used in fuel cells, H2 is converted to water and it gives little or zero exhaust ...
Experimental and theoretical investigations of magnesium-chlorine cycle and its integrated systems
(2015-01-01)
This study aims to investigate the feasibility of the Mg-Cl hybrid thermochemical cycle and to develop a more cost and energy effective cycle. There are five key elements of this study: (i) modeling and simulation of the ...
