applications. In addition to all this, a major chunk of energy is needed to liquefy the gaseous hydrogen, that is, 30% of net calorific value of hydrogen (120MJ/kg H2). Therefore, the vehicle manufacturing companies are possibility of employing liquid hydrogen as an alternative energy storage...
This Chinese translation discusses the idea that passenger aircraft will eventually use liquid hydrogen fuel. There is a large reserve of hydrogen and hydrogen poses no danger to the environment. Hydrogen has high calorific value, high specific heat, low density and low temperature. Aircraft will ...
As a renewable energy source, hydrogen combustion not only has an extremely high calorific value (1.43 × 108 J/kg) - roughly three times that of gasoline (4.6 × 107 J/kg) at the same weight - but also emits no greenhouse gases or sulfides [2]. Thus, a large-scale development and ...

Polychlorinated biphenyls means aromatic compounds formed in such a manner that the hydrogen atoms on the biphenyl molecule (two benzene rings bonded together by a single carbon-carbon bond) may be replaced by up to ten chlorine atoms; and Fluid means material or substance which flows or moves ...
Some hydrogen gas is produced and some carbon is deposited on the walls of the generator, but this deposited carbon can readily be burned off by cutting off the flow of fuel periodically and passing steam only through the heated generator. For example, assume that the object is to produce ...
The most common types of solid fuels include wood, biomass, peat, coal, coke, smokeless fuel, municipal waste, and rocket propellant. The calorific value for these fuels varies depending on the carbon content, hydrogen content, non-combustible or ash content, and water content. We can measure...
1.1.6Liquid and Gaseous Hydrogen and Hydrogen Mixtures Apart from the technologies themselves, hydrogen will be used in various applications in different forms. Aircraft apart, hydrogen can be stored on-board most vehicles in liquid or gaseous form or in metallic or other compounds. Vehicles using...
The cold energy may also be utilized in crushing and grinding at low temperature [11], desalination of seawater [12], cold storage and refrigeration [13], liquefaction of CO2 [14], liquefaction of hydrogen [15] and separation of light hydrocarbons [16]. Utilization of LNG cold energy ...
A process for the production of syngas and hydrogen starting from liquid hydrocarbons, gaseous hydrocarbons and/or oxygenated compounds, also deriving from biomasses, and mixtures t
