“…Of course, sustainable biofuels, strategies, and challenges are needed in this regard. In the future, the Government will develop biofuels with strategies not limited to biodiesel, including the development of bioethanol, bioavtur, and HVO, which are not limited to large-scale business (McCaffery et al, 2022). Furthermore, the development of advanced-generation biofuels, the use of non-CPO palm products, the use of biodiesel by-products, and populist standards based on customer wants are all encouraged.…”

This study aims to analyze biofuel use from oil palm as an alternative source of sustainable development. Data were obtained from the Scopus database with the last five years of publication. This research method uses a qualitative approach to the study of literature. Data analysis used bibliometric analysis with Vosviewer and NVIVO 12 plus software. The findings of this study indicate that several countries have used palm oil-based biodiesel as a transportation fuel, one of which is that Indonesia is the leading country in taking advantage of this opportunity. This can be seen from the development of the B30 from government and biodiesel programs which have become triggers for rising CPO prices worldwide and have impacted Fresh Fruit Bunches at the farm level. The study also found fluctuations in the publication of scientific research on biofuels. The most significant contribution to research articles comes from Malaysia. The university with the most number is University Malaya. The following research areas have the potential for further study: production of biofuels, vegetable oils, renewable diesel, and bio. Production energy, biodiesel, biomass, and biofuels are narratives of scientific research papers related to biofuels.

“…Today in the United States, biodiesel and RD are primarily used as relatively low-level blends in petroleum diesel to meet renewable fuel standard regulatory requirements. An exception is California, where blends of biodiesel into RD to create a 100% low-carbon fuel have begun to be used to meet state-specific regulatory requirements (California Low Carbon Fuel Standard) as well as evaluated for reducing tailpipe emissions . The motivation for blending biodiesel into RD is that, for standalone production facilities, biodiesel is significantly less expensive to produce .…”

While today's biomass-based diesel fuels are used at relatively low blend levels in petroleum diesel, decarbonization of the heavy-duty trucking and off-road sectors is driving increasing use of higher level blends and the combination of hydroprocessing-derived renewable diesel (RD) with biodiesel (fatty acid methyl esters) to create a 100% renewable fuel. However, little data are available on the properties of biodiesel blends over 20 vol % into RD or conventional diesel, despite the potential for properties to fall well outside the normal range for diesel fuels. Here, we evaluate the properties of 20−80% blends of a soy-derived biodiesel into RD and petroleum diesel. Properties measured were flash point, cloud point, cetane number, surface tension, density, kinematic viscosity, distillation curve, lower heating value, water content, water solubility in the fuel, lubricity, and oxidation stability. Density and viscosity were measured over a wide temperature range. A key objective was to reveal properties that might limit blending of biodiesel and any differences between biodiesel blends into RD versus petroleum diesel and to understand research needed to advance the use of high-level blends and 100% renewable fuel. Properties that may limit blending include the cloud point, viscosity, distillation curve, and oxidation stability. Meeting cloud point requirements can be an issue for all distillate fuels. For biodiesel, reducing the blend level and use of lower cloud point hydrocarbon blendstocks, such as No. 1 diesel or kerosene, can be used in winter months. Alternatively, a heated fuel system that allows for starting the vehicle on conventional diesel before switching to pure biodiesel (B100) or a high-level blend has been successfully demonstrated in the literature. Some biodiesels can have kinematic viscosity above the upper limit for diesel fuels (4.1 mm 2 /s), which will limit the amount that can be blended. Biodiesel boils in a narrow range at the very high end of the No. 2 diesel range. Additional research is needed to understand how the high T90 of B100 and high-level blends and the very low distillation range of B100, some RD samples, and high-level biodiesel blends impact lube oil dilution, engine deposits, and diesel oxidation catalyst light-off. Blending with No. 1 diesel or kerosene or biodiesel-specific engine calibrations may mitigate these issues. Oxidation stability of higher level blends is poorly understood but may be addressed through the increased use of antioxidant additives. Finally, high-level biodiesel blends and B100 will have significantly higher density, viscosity, and surface tension compared to conventional diesel. In combination with the high boiling point, these properties may impact fuel spray atomization and evaporation, and additional research is needed in this area.

“…More specifically, E-fuel can be defined as all fuels produced by using renewable electricity from renewable sources (hydro, wind, or solar) with low carbon emissions, making them renewable fuels of non-biological origin used as feedstock or as an energy carrier with the purpose of mainstreaming renewable energy in transport vehicles [11]. On the other hand, synthetic fuels obtained either by pyrolysis or by catalytic hydrogenation of any triglyceride of biological origin are currently designated by different names, such as green diesel [12][13][14][15][16], renewable diesel [17][18][19][20][21][22], bio-hydrogenated diesel (BHD) [23][24][25], hydrogenated vegetable oils (HVOs) [26][27][28][29], alternative fuels [29][30][31][32][33], or advanced biofuels [34][35][36]. Furthermore, according to Figure 1, in the last decade, there has been an impressive increase in scientific publications that address the transformation of vegetable fats and oils into alkanes through different deoxygenation processes [36].…”

Nowadays, there is an intense debate in the European Union (EU) regarding the limits to achieve the European Green Deal, to make Europe the first climate-neutral continent in the world. In this context, there are also different opinions about the role that thermal engines should play. Furhermore, there is no clear proposal regarding the possibilities of the use of green hydrogen in the transport decarbonization process, even though it should be a key element. Thus, there are still no precise guidelines regarding the role of green hydrogen, with it being exclusively used as a raw material to produce E-fuels. This review aims to evaluate the possibilities of applying the different alternative technologies available to successfully complete the process already underway to achieve Climate Neutrality by about 2050, depending on the maturity of the technologies currently available, and those anticipated to be available in the coming decades.
