Alternative Fuels – Biofuels, Hydrogen, Syngas

This chapter discusses the topic of alternative fuels and concentrates on biofuels, hydrogen, and syngas, their production, properties, their use in industry, and their importance to the environment. Biofuels are renewable energy sources that can be produced out of biomass, vegetable oils and waste products, and these fuels decrease reliance on fossil fuels. Hydrogen is offered as a clean carrier of energy, and the only by-product upon combustion is water, which makes it suitable for fuel cell and sustainable energy use. Syngas is a mixture of H₂ and CO, formed through the process of gasification of natural gas, biomass, or coal, and it is used as a flexible precursor in chemical production and energy production. It talks about methods of production, energy content, storage, handling and industrial use in the generation of power, transport and chemical manufacture. The positive environmental effects (such as the decreased emission of greenhouse gases and sustainable use of resources) are discussed, as well as such drawbacks as high costs of production, storage security, and technology. Using a combination of chemical principles, process engineering and industrial case studies, students can understand how to design and implement alternative fuel technology. Renewable energy, environmental engineering, sustainable transportation and chemical process development careers all depend on the knowledge of alternative fuels.
