Alcoholic Fuels: An Overview
Published in Shelley Minteer, Alcoholic Fuels, 2016
In today’s fuel market, methanol and ethanol are the only commercially viable fuels. Both methanol and ethanol have been blended with gasoline, but ethanol is the current choice for gasoline blends. Methanol has found its place in the market as an additive for biodiesel and as a fuel for direct methanol fuel cells, which are being studied as an alternative for rechargeable batteries in small electronic devices. Currently, butanol is too expensive to compete with ethanol in the blended fuel market, but researchers are working on methods to decrease cost and efficiency of production to allow for butanol blends, because the vapor pressure difference has environmental advantages. Governmental initiatives should ensure an increased use of alcohol-based fuels in automobiles and other energy conversion devices.

However, additional safety measures need to be taken when handling methanol because pure methanol, unlike ethanol, burns with an invisible flame. Moreover, because methanol is poisonous, contact with skin and eyes should be avoided. Besides use in internal combustion engines, methanol can be used in fuel cells, directly in the Direct Methanol Fuel Cell (DMFC), and indirectly after conversion into hydrogen.

The emission reduction technology of carbon dioxide provides opportunities for the sustainable development of the environment. The primaryidea of CO2 catalytic conversion is the effective production of valuable chemicals. The more environmentally friendly methanol fuel are also favorable for large-scale transformation than fossil fuels since methanol is easy to transport and store. According to NASA report, mars has a natural condition for water and carbon dioxide. As a result, methanol will be the optimal fuel for mars missions. Many countries are developing low-cost vehicles using methanol as an alternative fuel, though methanol using as a potential fuel in the future also faces huge challenges.
