As a response to the threat of global climate change, a number of technologies have been proposed in which the carbon dioxide produced by combustion of fossil fuels at power stations is captured and stored. A leading option is based on the pre-combustion decarbonisation of fossil fuels to produce hydrogen-rich fuel gases. Such decarbonisation processes integrate the production of a synthesis ga...

Flame control, particularly at very lean conditions, is a critical requirement for external combustion power sources such as thermoelectric and thermophotovoltaic generators. The availability of in-situ produced hydrogen from JP-8 fuel reforming presents a potential supply of hydrogen on the battlefield without adding a second fuel to the logistics system. Dual firing of hydrogen with light hyd...

The options for the regeneration of a Diesel Particulate Filter (DPF) using hydrogen rich gas are investigated. The advantages of using hydrogen rich gas for this purpose are described. The system requirements for such a system are also evaluated. The use of a plasmatron fuel converter for the onboard generation of hydrogen rich gas from diesel fuel is discussed. The advantages of homogeneous, ...

The present study conducted experimental investigation on combustion and emission characteristics of compression ignition engine using diesel as pilot fuel and methane, hydrogen and methane/hydrogen mixture as gaseous fuels at 1800 rev min. The effect of gaseous fuel on peak cylinder pressure and heat release is modest at low to medium loads. At high load, the high combustion temperature and hi...

H as this happened to you? You have a layover between flights, would like to use your computer and cell phone, but both sets of batteries are drained and the nearby electrical outlets are being used. What if you could instead recharge your electronic devices with a little sugar from the nearby coffee stand? With help from electricity-producing microorganisms, known as electricigens, some day yo...

Hydrogen is an important chemical material that is utilized in a large scale in synthetic chemical industries in modern society. On the other hand, technologies for utilizing hydrogen as clean source of energy are considered to assume an important position in order to overcome problems of lack of energy and environment in future. Hence, fuel cells that store hydrogen and operate using it as fue...

Aluminum is the most abundant metal in the Earth's crust and a highly sought after fuel source due to its extreme energy density. It has the ability to produce large quantities of hydrogen and heat when reacted with water making it an attractive fuel for underwater vehicles and ocean sensor platforms. The biggest challenge in using aluminum as a fuel has been overcoming the rapidly-forming oxid...

The proton exchange membrane (PEMFC) fuel cell represents the energy of the future, in parallel with hydrogen. However, this technology must meet many technical challenges related to performance and durability before being sold on a large scale. It is well known that these challenges are closely linked to water management. This paper develops and implements a model of PEM fuel for simulation to...
