Hydrogen, which can be produced by water electrolysis, can play an important role as an alternative to conventional fuels. It is regarded as a potential future energy carrier. Photovoltaic arrays can be used in supplying the water electrolysis systems by their energy requirements. The use of...

The continuous increase in energy demand and the growing attention on global warming worldwide have aroused great research interest in a novel near zero emission energy utilization system which is based on CaO sorption enhanced gasification. This paper presents the experimental results of...

A high-temperature polymer electrolyte membrane fuel cell (HT-PEMFC) has a major advantage over a low-temperature polymer electrolyte fuel cell (LT-PEMFC) demonstrated by a tolerance to a higher CO content in the hydrogen feed and thus a simpler fuel processing. In this study, a direct...

In this paper, a new market integration approach for responsive loads is proposed. Large, spatially-distributed populations of heat pumps, electric vehicles, and electrolyzers are integrated into the conventional security constrained economic dispatch formulation using a hierarchical load...

Hydrogen production plays a very important role in the development of hydrogen economy.

This study presents the numerical simulation on the performance of mini-scale reactors for hydrogen production coupled with liquid methanol/water vaporizer, methanol/steam reformer, and methanol/air catalytic combustor. These reactors are designed similar to tube-and-shell heat exchangers. The...

As a promising method of hydrogen production by utilizing renewable energy sources for future, water electrolysis is one of the favorite fields of the study and scientific experiment for many researchers all around the world. One of the most popular related research areas is the efficiency...

Hydrogen is considered as the fuel for next generation and extensive research is being pursued for search of new techniques for hydrogen production from renewable sources. There is a diverse collection of hydrogen production processes at their different stages of development. This review paper...

Pt loaded MgO, Al2O3, CeO2, TiO2 and SiO2 catalysts were prepared by loading pre-synthesized Pt colloids on support and used for the aqueous-phase reforming (APR) of glycerol to investigate the influence of support properties on catalytic performance. The conversion of glycerol, rate of hydrogen...
