Abstract

A “fuel” is generally defined as any material that can be altered to release energy in a controlled manner in the form of heat and/or work. Fuels can be solids, liquids, or gases. Conventional fuels are of two types: fossil fuels and nuclear fuels. The word “altered” in the above definition signifies a chemical or physical process to which the fuel is subjected to release energy. Nuclear fuels, such as fissionable uranium, are “altered” through a chained nuclear reaction of fission to generate useful energy in the form of high temperature heat. Fossil fuels represent fossilized biomass, which stores carbon out of the natural carbon cycle in sediments for a long time. When combusted, fossil fuels release the carbon into the atmosphere in the form of carbon dioxide, thus contributing to global warming. Biomass also emits carbon dioxide when combusted; however, the emitted carbon is only returned in the global carbon cycle in this way; thus, biomass is considered a renewable energy resource. Biomass represents biological material of recently living organisms, which is regarded both as an alternative fuel and as a source of materials for synthetic fuels production.
