Thermoelectric (TE) generator converts heat to electric energy by thermoelectric material. However, heat removal on the cold side of the generator represents a serious challenge. To address this problem and for improved energy conversion, a thermoelectric generation process coupled with methanol...

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...

The hydrogen economy presents an appealing energy future but its implementation must solve numerous problems ranging from low-cost sustainable production, high-density storage, costly infrastructure, to eliminating safety concern. The use of renewable carbohydrate as a high-density hydrogen...

This paper proposes a polygeneration system based on a multi-input chemical looping combustion system, which generates methanol and electricity, through the use of natural gas and coal. In this system, the chemical looping hydrogen (CLH) production system and the coal-based methanol production...

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

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...

The aluminum energy conversion processes have been characterized to be carbon-free and sustainable. However, their applications are restrained by aluminum production capacity as aluminum is never found as a free metal on the earth. This study gives an assessment of typical aluminum-based energy...

The conversion of lipid-extracted microalgal biomass residues (LMBRs) into hydrogen plays the dual role in renewable energy production and sustainable development of microalgal biodiesel industry. An anaerobic fermentation process to covert LMBRs into hydrogen was investigated in this work....

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...

High temperature fuel cells are a promising technology for ultra-low emission power generation. This paper presents a novel poly-generating system capable of greater than 80% (LHV CH4) co-production efficiency with carbon capture and liquefaction. The proposed system synergistically integrates...
