Additionally, the manufacturing process of second-generation biofuels from
lignocellulosic biomass is currently under consideration. On the other hand, it
involves energy-intensive degradation of biomass comprising lignocellulosic by
pretreatment (Kumar and Sharma 2017). Biofuels of the second generation may be
described as biochemical or thermochemical systems used to turn the biomass into a
liquid. Second-generation ethanol or butanol can entirely be processed by means of
biochemical technology (Devi et al. 2019). Second-generation thermochemical
renewable energy sources may remain extra prevalent to readers, but there are
multiple fuels now generated extensively from fossil fuels utilizing production
processes who are in some contexts extremely similar to what is used for bioenergy
production. These fuels comprise fluids from Fischer-Tropsch (FTL), methanol, and
dimethyl ether (DME). Worldwide, several projects are underway to commercialize
biofuels of the second generation. And in case of biochemical fuels, there is a need
for breakthroughs in microorganism science and engineering designed to handle
different feedstocks, accompanied by large-scale demonstrations to prove economic
viability. It may take some 10–20 years before commercial production starts radically. And in the true meaning of thermochemical fuels, various equipment components required for biofuel processing are now commercially targeted at fossil fuel
conversion applications, and the method is very oblivious to the particular feedstock
input, needing fewer creation and demonstration efforts. The commercial production
of thermochemical biofuels can commence in 5–10 years.
While some consideration has been given to the third generation of renewable
energy of photosynthetic organisms such as cyanobacteria and algae, the rate of cell
transformation is very small and thus the metabolite productivity is relatively lower
(Sheehan 2009). Microalgae are monocellular or basic multicellular organisms and
can be prokaryotic or eukaryotic by nature. Microalgae by nature poses the ability to
prosper in fresh or salt waters. Due to the standard cellular structure of the
microalgae they can skillfully convert organisms to our solar power. Planet
microalgae is believed to be among the earliest living life forms on earth. There is
a huge microalgae variant, and some 300,000 microalgae species. Among these
different ranges of microalgae, almost species ensure about 80% oil content.
Microalgae have the potential to be used as biodiesel harvest.
Even though the transport sector pays much concern to biofuels, the use of
biofuels for cooking is a feasible use of broad global significance, especially in
developing countries’ rural areas. For all cases, the combustion of cooking biofuels
will create emissions of contaminants that are lower (or much lower) than the
emissions from solid fuel cooking. Around 3 billion people in developed countries
cook with solid fuels and experience major damage to their health from the resulting
indoor air pollution. Biofuels may thus conceivably be influential in illuminating the
health of billions of individuals. It is worth remarking that the scale of biofuel
production required to meet the cooking energy needs is much lesser than that
essential to meet the transport fuel requirements (Chen et al. 2015).
