“…The production of RD is achievable through thermochemical processes and biochemical process. Vegetable oil and animal fats are subjected to hydroprocessing or pyrolysis while lignocellulosic biomass undergo pyrolysis, Fischer-Tropsch (FT) process, biological conversion of sugars (i Nogué et al, 2018;Okeke et al, 2020). Among the technologies, hydroprocessing is performed directly on natural triglycerides to obtain RD, which involved a series of complex reactions.…”

Renewable diesel as a potential sustainable energy source in future requires catalysts to convert the feedstocks into end products. Among various type of catalysts, bimetallic catalysts are widely applied in the renewable diesel production due to their unique catalytic properties and enhanced catalytic activities, which differ from their parent monometallic catalysts. This mini review comprised of the brief introduction on technologies in producing renewable diesel and aims to discuss the underneath knowledge of synergistic interactions in bimetallic catalysts that synthesized through various techniques. The novelty of this review reveals the recent development of renewable diesel production, highlighting the mechanisms of bimetallic catalysts in the enhancement of the catalytic activity, and exploring their possibilities as practical solution in industrial production.

“…Ben Hnich et al found that FT palm oil diesel and gasoline could outperform their fossil counterparts in both global warming (7.65 kg CO 2 -eq/GJ) and resource scarcity (28.58 kg oil-eq) while worsening other environmental categories such as fine particulate matter formation, freshwater eutrophication, and terrestrial acidification. Similarly, Okeke et al studied FT miscanthus diesel finding that it could decrease slightly carcinogenic, noncarcinogenic, and ecotoxicity, relative to the fossil analog, while massively increasing ozone depletion, smog, acidification, eutrophication, and respiratory effects.…”

“…However, its performance on impacts beyond global warming remains unclear because they are often omitted. − This simplification is critical because electro-fuels may shift environmental burdens to other categories. Notably, this collateral damage has been observed in biomass-based synthetic fuels, − low-carbon power mixes, , carbon capture and utilization, , and FT electro-gasoline, to mention a few. Quantifying these potential adverse effects of electro-fuels is considered critical for designing optimal technological roadmaps for the transport sector.…”

Electro-fuels are seen as a promising alternative to curb carbon emissions in the transport sector due to their appealing properties, similar to those of their fossil counterparts, allowing them to use current infrastructure and state-of-the-art automotive technologies. However, their broad implications beyond climate change remain unclear as previous studies mainly focused on analyzing their carbon footprint. To fill this gap, here, we evaluated the environmental and economic impact of Fischer–Tropsch electro-diesel (FT e-diesel) synthesized from electrolytic H 2 and captured CO 2 . We consider various power (wind, solar, nuclear, or the current mix) and carbon sources (capture from the air (DAC) or a coal power plant) while covering a range of impacts on human health, ecosystems, and resources. Applying process simulation and life cycle assessment (LCA), we found that producing e-diesel from wind and nuclear H 2 combined with DAC CO 2 could reduce the carbon footprint relative to fossil diesel, leading to burden-shifting in human health and ecosystems. Also, it would incur prohibitive costs, even when considering externalities (i.e., indirect costs of environmental impacts). Overall, this work highlights the need to embrace environmental impacts beyond climate change in the analysis of alternative fuels and raises concerns about the environmental appeal of electro-fuels.

“…Therefore, the FU is 1 kg of methanol produced at plant. This is similar to [29], where the FU was 1 kg of synthetic biodiesel produced at plant, [7] where the FU was defined as 1t methanol produced by the selected technical route, and [30] that used: one gasoline gallon equivalent of drop-in diesel, which is compared against the conventional petroleum-derived diesel.…”

The main purpose of this work is to examine the techno-economics and environmental assessment of the Solid Recovered Fuel and Lignite to methanol pathway. Methanol is produced by gasifying the solid fuels to carbon monoxide and hydrogen and then reacting to produce methanol under pressure during the methanol synthesis process. The data obtained from the partners is used to adapt this study for the liquid fuel synthesis application. The in-house personal computer-based process simulation package, ECLIPSE, is used to perform process modelling and the techno-economic assessment of methanol production. The @Risk 8.2© software is used to estimate the cost contingency of the project. The SimaPro© software package was used to carry out the Life Cycle Assessment (LCA). The gasifier plant contributes significantly to the capital costs. The results show that increased Solid Recovered Fuel (SRF) in the feedstock mix has favourable economics due to the negative SRF charges resulting in a lower break-even selling price (BESP) than feedstock mixes with higher ratios of Lignite. Plant availability, capital investment and the time value of money are the factors that have the greatest impact on BESP. Increasing the SRF in the feedstock mix decreases the Global Warming impact of the methanol production compared to higher proportions of Lignite. However, the resultant impact is much greater than that of a natural gas reformer. Furthermore, the employment of off-gas recovery and carbon capture can further reduce both the Global Warming impact and the overall Single Score of the process, making it favourably comparable to the natural gas water gas shift configurations.
