“…The second sensitivity analysis considers the effect of PVELC cost reduction on the preferred hydrogen production technology. From the assessed technologies, only PVELC can still experience cost reduction as it is still an emerging technology, whereas the other two technologies are more mature 53 . Recent studies have noted a significant drop in the cost of PVELC technology, 53–55 which also affects the cost of HVO‐PVELC.…”

This study also wanted to explore the possibility of adding HVO to the future diesel blend by tackling its most challenging problem, which is the cost.…”

The trend towards increasing biofuel blending mandates in several countries has raised a sustainability trilemma, especially for biofuels derived from palm oil. This study aims to find the most sustainable hydrogen production technology for the production of hydrogenated vegetable oil (HVO) and biofuel blending. It assesses the sustainability of palm‐oil‐derived biofuel blending of biodiesel (FAME), HVO, and petroleum diesel. There are three hydrogen production options for HVO: steam methane reforming (SMR), biomass gasification (BG), and electrolysis from solar energy (PVELC). The use of any production option depends on a combination of fuel quality standards and the prioritized sustainability considerations. The fuel quality aspects consist of constraints on the quality of the blend based on EURO‐2, EURO‐4, and EURO‐5 fuel standards, while sustainability priorities lead to varying policy preferences involving economic, environmental, and social sustainability considerations. There are two approaches to determine the most sustainable blend: using the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method and using the sustainability index. The results show that scenarios that favor the economic dimension tend to produce a higher FAME blend, whereas those that prioritize the environment emphasize higher HVO blending with PVELC as the hydrogen production technology. Finally, any scenario that prefers the social aspects tends to produce higher biofuel blending. Overall, to achieve higher sustainability, higher biofuel blending is needed. The policy analysis section concludes that the biofuel policy direction should focus more on combining HVO and FAME so that each can offset the disadvantages of the other. © 2022 Society of Chemical Industry and John Wiley & Sons, Ltd.

“…Nevertheless, their LCA suggested that CO 2 net zero emissions will be only achieved with very low electricity GHG intensity, making necessary the use of RES, especially for H 2 production. For this reason, an increasing number of studies are now extending the boundaries of the studies to technologies for carbon capture and H 2 production [10,12,21], to the comparison of different sources of water splitting [11] or to purely the analysis of H 2 cost for making CO 2 valorization cheaper [1]. But this factor may have overshadowed the most recent advances on catalytic systems for CO 2 hydrogenation, as most of the work is done using kinetic models for the classic Cu-ZnO-Al 2 O 3 catalyst, which performance is inferior to most state-of-the-art catalysts [22].…”

Bioenergy with carbon capture and storage (BECCS) has the potential to produce negative emissions. This study assessed the overall energy efficiency and carbon dioxide (CO2) avoidance costs and emission footprint following the integration of BECCS with a polygeneration system (BECCS-PS) for the co-production of green electricity and methanol. The process was simulated in Aspen Plus and Aspen HYSYS v.11. Oil palm empty fruit bunches were used as the feed in a biomass integrated gasification combined cycle power plant. The flue gas, which contained CO2, was captured for methanol synthesis and carbon storage. Green hydrogen for use in methanol synthesis was produced through proton exchange membrane (PEM) electrolysis powered by solar PV (PV-PEM) and geothermal power with double-flash technology (GEO-PEM). The environmental impacts of the process were investigated by a life cycle assessment and the economic aspects were evaluated using the levelized cost method. The overall system efficiency was higher in the PV-PEM scenario than in the GEO-PEM scenario. For any production capacities, the green electricity generated from the BECCS-PS plant resulted in negative emissions. A biomass power plant with a low production capacity generated higher production and CO2 avoidance costs than that with a larger production capacity. The CO2 − eq emissions and costs for methanol production in the PV-PEM scenario were larger than those in the GEO-PEM scenario, with values of -0.83 to -0.70 kg CO2 − eq/kg MeOH and 1,191–1,237 USD/ton, respectively. The corresponding values were − 1.65 to -1.52 kg CO2 − eq/kg MeOH and 918–961 USD/ton, respectively, for the GEO-PEM scenario. Graphical Abstract
