Achieving a successful transition to hydrogen-powered vehicles in the U.S. automotive market will require strong and sustained commitment by hydrogen producers, vehicle manufacturers, transporters and retailers, consumers, and governments. The interaction of these agents in the marketplace will...

The H2A Production Model analyzes the technical and economic aspects of central and forecourt hydrogen production technologies. Using a standard discounted cash flow rate of return methodology, it determines the minimum hydrogen selling price, including a specified after-tax internal rate of...

In this paper, the effects of light intensity on the hydrogen production of Rhodobacter sphaeroides 1.1737 using swine manure wastewater as substrate were investigated. The results show that the increase in light intensity increases both hydrogen production rate and total hydrogen evolved by...

Calcined dolomite is a good catalyst in terms of its activity for gasification of residue derived from biomass hydrolysis for hydrogen production, whereas its fragility can cause trouble during operation. A novel modification method aimed at improving the strength of the calcined dolomite has...

Transformation towards sustainable energy system requires substantial changes in current energy production and consumption patterns. This paper addresses system transition as a valuable approach in contributing to these changes. The main purpose of the paper is to develop and apply a framework...

In this article, the conceptual design of biomass steam gasification (BSG) processes using raw oil palm (ROP) and torrefied oil palm (TOP) are examined in an Aspen Plus simulator. Through thermodynamic analysis, it is verified that the BSG process with torrefied feedstock can effectively enhance...

Western Canada is endowed with considerable reserves of deep un-mineable coal, which can be converted to syngas by means of a gasification process called underground coal gasification (UCG). The syngas can be transformed into hydrogen (H2) through commercially available technologies employed in...

The application of the biocathode for hydrogen production in a Microbial Electrolysis Cell (MEC) is a promising alternative to precious metal catalysts. However, biocathodes are still in the improvement and development stages and require a deep understanding of the bioelectrochemical mechanisms...

PDMS (Polydimethylsiloxane) is a typical material used to fabricate optofluidic microreactors for photocatalytic water splitting application. However, conventional direct catalyst coating methods are unable to load catalysts firmly and uniformly on the PDMS substrate, which results in weak bond...

The Aspen Plus process simulation package is used to evaluate the characteristics of the four-step Cu–Cl thermochemical water splitting cycle in terms of energy and exergy, to support the ultimate development of a pilot plant. Alternative designs for the heat exchanger network using Aspen...
