An Overview of Algae for Biodiesel Production Using Bibliometric Indicators

Abstract

Algae are a desirable biodiesel feedstock because they take up little space, have a high algal-cell biomass per unit area, and can sustainably meet a large portion of the world’s future energy needs. Using several bibliometric indicators, this study assesses the research productivity of algae for biodiesel production. The dataset was retrieved from the Scopus database using an appropriate keyword search. The VOSviewer v1.6.18 and Biblioshiny in R -studio were then utilised for bibliometric analysis and network visualisation. The study found that, with the first article being published in 1990 and an annual scientific growth rate of 14.76%, research on algae for the generation of biodiesel is still in its early phases. Although the possibility of utilising algae to produce biodiesel was originally mentioned in 1990, it was only until 2006 that several researchers started to show an interest in the subject. 101 articles were published in 2015, which is the most ever. The most prolific countries in terms of publications, ongoing collaborations and cooperation, best publishing institutions, and prestigious journals, as well as the most productive researchers and the most highly referenced works in the field, have all been recognised and presented. Finally, a keyword co-occurrence analysis of the subject was presented and discussed to provide research insights into the field. The bibliometric indicators of the study are intended to aid researchers in finding potential research topics, high-quality scientific literature, and suitable journals for publishing research on algae for biodiesel production.

Techno-economic analysis of biodiesel and bioethanol production from Chlorella sp. algae biomass

“…algae biomass as a feedstock for biodiesel and bioethanol production. The study included technology selection for cultivation, harvesting, trans-esterification for biodiesel proudction, hydrolysis, and fermentation for bioethanol production [7], [9]- [11].…”

Exploring Exogenous Indole-3-acetic Acid’s Effect on the Growth and Biochemical Profiles of Synechocystis sp. PAK13 and Chlorella variabilis

“…In this regard, microalgae are a rich source of valuable compounds, including proteins, lipids, pigments, and carbohydrates, which have significant economic potential [ 3 , 4 ]. For instance, the lipids extracted from microalgae can be converted into biodiesel, which is a clean-burning alternative to traditional diesel fuel [ 5 ]. Thus, microalgae are used to produce biofuels, which are renewable energy sources that have the potential to replace fossil fuels [ 6 , 7 ].…”

One-Pot Synthesis of Biodiesel from Acid Oil Using a Switchable Solvent, 1,8-Diazabicyclo[5.4.0]undec-7-ene (DBU), as a Bifunctional Catalyst

“…Limited fossil fuel availability together with environmental concerns has triggered the need for renewable energy. Biodiesel, a clean fuel comprising fatty acid alkyl esters, is a promising replacement for fossil fuel due to its biodegradability, renewability, and low emissions of hydrocarbon, SO 2 , and CO 2 [1,2]. In addition, biodiesel is adaptable to existing diesel engine with or without blending with petroleum due to its combustion efficiency [3][4][5].…”
