“…Energy is fundamental to human survival, development and growth (Coelho et al, 2018;Le et al, 2021;Vieira et al, 2021). Energy is used to produce goods and services or to meet the service requirements of the final demand sectors (Chai et al, 2009;Weiss de Abreu et al, 2021).…”

Promoting the use of renewable energy sources has become an important policy strategy for mitigating climate change and for providing better energy security and financial sustainability. To overcome the problems generated by non-renewable energy sources, it is essential to use new energy sources. A literature review was conducted to investigate and understand the opportunities for implementing new renewable energy sources. Agricultural residues have great potential to receive significant consideration worldwide as an alternative, sustainable, and green energy source. The use of agricultural residues for bioenergy generation is a broad and favourable scenario for exploration. This review identified potential and almost unexplored research approaches with the aim of contributing and promoting researchers to deliver technological solutions for the society and industrial sectors. For example, a potentially promising technological solution would be for industries that produce machinery and agricultural implements to adapt their harvesters for different grain crops, to collect these agricultural residues simultaneously during harvest and readily perform granulation, compaction (pressing), pelletizing or briquetting directly on the property. Further studies are required to investigate the use of agricultural residues for bioenergy generation, which can contribute to the diversification of the energy matrix. Accordingly, in this review, several challenges and future research perspectives have been presented, such as suggestions for future research on how to collect, transport, process, market and use these agricultural residues to generate bioenergy, aiming at reducing the dependence on fossil fuels.

“…Brazil was one of the developing countries that most applied capital in processes using renewable sources of energy, corresponding to an investment of approximately 73%. This generated a change in the Brazilian energy matrix, as the fossil fuels that dominated the means of production began to correspond to only 22% of the production of electric energy [23]. By increasing the use of renewable sources of energy, hydrogen began to be seen as a fuel that could replace petroleum-based products in the automobile industry.…”

The unbridled use of fossil fuels is a serious problem that has become increasingly evident over the years. As such fuels contribute considerably to environmental pollution, there is a need to find new, sustainable sources of energy with low emissions of greenhouse gases. Climate change poses a substantial challenge for the scientific community. Thus, the use of renewable energy through technologies that offer maximum efficiency with minimal pollution and carbon emissions has become a major goal. Technology related to the use of hydrogen as a fuel is one of the most promising solutions for future systems of clean energy. The aim of the present review was to provide an overview of elements related to the potential use of hydrogen as an alternative energy source, considering its specific chemical and physical characteristics as well as prospects for an increase in the participation of hydrogen fuel in the world energy matrix.

“…12,18 Furthermore, J100 has a high oleic acid content, which is ideal for lubrication, 19 whilst C100 has a low linoleic acid content, which facilitates the low oxidation desired for biodiesels. 20,21 Mineral oils contain an antiwear additive and has the lowest coefficient of friction (COF) and wear scar diameter (WSD). 2,12 Therefore, combining J100 (high oleic acid content), C100 (low linoleic acid content), and a mineral oil should improve lubrication performance.…”

This present study formulated eco‐friendly lubricants by combining non‐edible vegetable oils with a mineral oil and investigated their efficacy on the friction and wear characteristics of four AISI 52100 chrome steel balls. Multiple formulations containing varying combinations of 0 to 100 vol% of a mineral oil SAE 15W40 (S100), castor oil (C100), and jatropha oil (J100) were prepared using the sonification technique in an ultrasonic homogeniser. A fourier transform spectrometer (FTIR) was then used to investigate the molecular vibrations of each formulation. A tribological test was also performed with a four‐ball tribometer according to ASTM D4172‐94 engineering standards. Finally, a scanning electron microscope (SEM) equipped with an energy dispersive X‐ray spectroscope (EDX) was used to examine surface morphologies. The 80% S100, 10% C100, and 10% J100 (S80C10J10) formulation provided excellent tribological performance as it contained fatty acids composed of carbohydrates and carbonyl groups, particularly polysaccharides and glycerols.
