Hydrogen fuel in transportation

Carbon Nanofibers as a Hydrogen Storage Medium for Fuel Cell Applications in the Transportation Sector

In the push to replace fossil fuels and their conversion into energy via the internal combustion engine with cleaner and more renewable energy sources for the transportation sector, hydrogen and the fuel cell have emerged as the best candidates for the future. Hydrogen is readily available in near limitless quantities and produces only water and heat as a byproduct when reacted with oxygen. Whi...

Hydrogen Fuel in Fusion Plasmas

Hydrogen Fuel Cell Automobiles

With gasoline now more than $2.00 a gallon, alternate automobile technologies will be discussed with greater interest and developed with more urgency. For our government, the hydrogen fuel cell-powered automobile is at the top of the list of future technologies. This paper presents a simple description of the principles behind this technology and a brief discussion of the pros and cons. It is a...

Sustainable fuel for the transportation sector.

A hybrid hydrogen-carbon (H(2)CAR) process for the production of liquid hydrocarbon fuels is proposed wherein biomass is the carbon source and hydrogen is supplied from carbon-free energy. To implement this concept, a process has been designed to co-feed a biomass gasifier with H(2) and CO(2) recycled from the H(2)-CO to liquid conversion reactor. Modeling of this biomass to liquids process has...

Hydrogen or methanol in the transportation sector?

Governmental policies and international treaties that aim at curbing the emissions of greenhouse gases and local pollutants can be expected. These regulations will increase the competitiveness of CO2-neutral energy sources, i.e., renewables, nuclear or fossil fuels with CO2-sequestration. The purpose of this paper is to assess the relative competitiveness of methanol and hydrogen as fuels in th...
