Fuel cells are considered as one of the most promising devices for standalone/grid connected distributed generations due to its cleanliness, modularity and higher potential capability. In the present energy scenario, Fuel cells combined with other renewable technologies are gaining attraction. This paper focuses on the combination of Fuel Cell (FC) and Ultra-Capacitor (UC) systems for sustained...

The exploitation of fossil fuels at a tremendous scale, especially after the industrial revolution in 18th century, has instigated damage to environment. usage fossil-based results an excess accumulation greenhouse gases (GHGs), i.e., mainly CH4 and CO2, atmosphere. This is reason for decreased air quality, increased global warming, disturbed seasonal variations many world regions. Hydrogen (H2...

Title of Document: ELECTROCHEMICAL OXIDATION KINETICS OF HYDROGEN AND HIGHER HYDROCARBON FUELS ON SOLID OXIDE FUEL CELLS. Oktay Demircan, Ph.D., 2007 Dissertation Directed By: Professor Bryan W. Eichhorn, Department of Chemistry and Biochemistry Solid oxide fuel cells (SOFCs) are promising electrochemical energy converting devices due to their ability to use not only hydrogen but also hydrocarb...

The traditional methodology includes a carbon-chain shortening strategy to produce bio-jet fuel from lipids via a two-stage process with hydrogen. Here, we propose a new solution using a carbon-chain filling strategy to convert C10 terpene and lipids to jet fuel ranged hydrocarbons with aromatic hydrocarbon ingredients in the absence of hydrogen.

The present project was conducted with the circumferential-fuel-jets inverse diffusion flame (CIDF) burner burning liquefied petroleum gas (LPG) enriched with 50% of hydrogen fuel (H2). The range of stable operation of the CIDF burner in terms of Reynolds number (from laminar to turbulent flow regions), equivalence ratio and fuel jet velocity of LPG of the 50% H2-LPG mixed fuel was identified. ...

R technological advances in the application of hydrogen fuel cells in the transport sector have drawn considerable attention and increased funding from both public and private sources over the past ten years. Th e International Energy Agency estimates that about US$1billion per year is currently being invested in public hydrogen and fuel cell research, development, test vehicles, prototype refu...

Carbons with slitlike pores can serve as effective host materials for storage of hythane fuel, a bridge between the petrol combustion and hydrogen fuel cells. We have used grand canonical Monte Carlo simulation for the modeling of the hydrogen and methane mixture storage at 293 K and pressure of methane and hydrogen mixture up to 2 MPa. We have found that these pores serve as efficient vessels ...

BACKGROUND Bio-jet fuels compatible with current aviation infrastructure are needed as an alternative to petroleum-based jet fuel to lower greenhouse gas emissions and reduce dependence on fossil fuels. Cradle to grave life cycle analysis is used to investigate the global warming potential and fossil fuel use of converting poplar biomass to drop-in bio-jet fuel via a novel bioconversion platfor...
