Alternative fuels: An overview of current trends and scope for future

Most of the alternative fuels have properties similar to those of the existing fuels, and therefore the technology required to handle them is already well known. Hydrogen is an exception to this, and its ignition properties are quite different from those of the conventional fuels. Difficulties are thus expected during the storage, transport, and use of hydrogen as a fuel. Other technologies are also discussed such as alternative routes to equivalents of conventional fuels, like CTL. Finally, the emulsified fuels including the use of oxygenates have been discussed.
