Using gas-to-liquids (GTL) technology will expand a new horizon as resources of crude oil diminish. Fischer–Tropsch synthesis (FTS) is a part of thermo-chemical route, which is used to produce chemicals, gasoline and diesel range fuel from synthesis gas derived from different sources,...

Biofuels have a potential to extend and diversify South Africa’s energy supply, thus reducing dependence on imported fuels and pollution levels. Despite several biofuel policies and mandates, biofuel development in South Africa has stalled in the legislative process and no large scale...

There has been a growing interest in jatropha- and sugarcane-based biofuels across Sub-Sahara Africa. Biofuel expansion in the region reflects policy concerns related to energy security, poverty alleviation and economic development. However, biofuels have also been linked to numerous...

The sustainability revolution is the defining challenge of our time to meet increasing needs in the energy−food−water nexus without compromising the ability of next generations. To feed the world, modern agriculture is primarily based on annual grain crops that replace native perennial plant...

The interest in algae based biofuels and chemicals has increased over the past few years because of their potential to reduce the dependence on petroleum-based fuels and chemicals. Algae is touted to be the most suitable and sustainable feedstock for producing green energy as the whole process...

Algae is a very promising source for renewable energy production since it can fix the greenhouse gas (CO2) by photosynthesis and does not compete with the production of food. Compared to microalgae, researches on biofuel production from macroalgae in both academia and industry are at infancy for...

Global outlook of biofuels turns out to be a full-fledged search focusing the viability and sustainability assets. The present day option for immediate and sustainable alternate fuels lies with algal biofuels. Algae are the most sustainable fuel resource in terms of food security and...

In an effort to reduce greenhouse gas emissions, renewable fuels (biofuels) are being developed and used in motor vehicles. The most common of these are bioethanol and biodiesel that are blended with petroleum based gasoline and diesel fuels at varying percentages. This provides some reduction...

To confront energy shortage, global warming and climate changes, biofuels derived from biomass have received increasing attention from the industry, academia and governments. Of the potential sources of biofuels a most promising one is the simple photosynthetic microalgae, which can be grown in...

One of the challenging issues faced by the modern world is the scarcity of fossil fuels, a result of the increasing use of fuel for transportation. Therefore, it is necessary to develop an alternative fuel source that can replace non-renewable fossil fuels. The use of biomass-derived fuels in...
