Drawbacks of first-generation biofuels : Challenges and paradigm shifts in technology for second- and third-generation biofuels
(2024) p.33-47- Abstract
In the 20th century, the scientific community recognized global climate change as a preeminent challenge facing our planet. The primary driver of this predicament was identified as the substantial reliance on fossil fuels, constituting approximately 80% of the world's energy consumption. The combustion of these fossil fuels, particularly those rich in carbon, led to the emission of greenhouse gases, notably carbon dioxide. The concurrent depletion of fossil fuel reserves compounded the urgency of addressing this issue. The escalating prices of oil over the past decade further accelerated the competitiveness of liquid biofuels with traditional petroleum-based transportation fuels, prompting a surge in global research and production...

In the 20th century, the scientific community recognized global climate change as a preeminent challenge facing our planet. The primary driver of this predicament was identified as the substantial reliance on fossil fuels, constituting approximately 80% of the world's energy consumption. The combustion of these fossil fuels, particularly those rich in carbon, led to the emission of greenhouse gases, notably carbon dioxide. The concurrent depletion of fossil fuel reserves compounded the urgency of addressing this issue. The escalating prices of oil over the past decade further accelerated the competitiveness of liquid biofuels with traditional petroleum-based transportation fuels, prompting a surge in global research and production endeavors. The utilization of first-generation biofuels has attained global prevalence, with biodiesel (bioesters), ethanol, and biogas emerging as the predominant types. These biofuels are now produced on a large scale globally, and their production processes are acknowledged as “mature technologies.” While diverse clean energy sources such as wind, solar, and hydropower offer sustainable alternatives, the significance of biomass lies in its unique ability to provide liquid fuels for transportation. Biofuels, sourced from biological entities such as plants, animals, microbes, and waste materials, present distinct advantages. In contrast to conventional fossil fuels with origins in ancient photosynthesis, biofuels are products of contemporary photosynthesis, involving the conversion of solar energy into chemical energy. The categorization of biofuels into different generations—first, second, third, and fourth—is based on the raw materials employed and the production methods utilized. This classification underscores the evolving nature of biofuel technologies and their potential to address the multifaceted challenges posed by climate change and fossil fuel depletion from a scientific perspective.
