Due to a rise in global temperatures, many fuel industries have searched for alternative energy sources that lower emissions rates in combustion engines. Although new energy sources show promise in reducing emissions and costs, large investments and arduous construction of infrastructure must occur for any effect to take hold. Bioethanol is a potential alternative energy source that, through investment into infrastructure and its related industries, can lead the way in reducing emissions. The purpose of this article is to highlight bioethanol’s advancements in various industries and its future in those industries.
Bioethanol has many applications in several industries across the world. Applications include fuel for power in combustion processes, fuel for fuel cells, feedstock for chemical companies, and fuel for cogeneration systems [1]. The broad application of bioethanol benefits current engines and fuel processes, serving as an alternative to regular petrol in engines. As an engine fuel, bioethanol can serve as an alternative for gasoline at any blend percentage, creating more efficient engines in the process [1]. Current engines tolerate up to 15% bioethanol blends without modifications. Bioethanol reduces emissions due to how it is produced [1]. One method of production involves using lignocellulose to break down biomass, and then extracting its sugars through using enzymes and hydrolysis [1].
