Abstract

Hydrotreated Vegetable Oils (HVO) are gaining prominence due to their low carbon dioxide emissions and compatibility with existing internal combustion engines. This study presents a comprehensive analysis of HVO production processes, emphasizing advanced hydrotreating techniques, the types of raw materials utilized, and the challenges inherent to each method. Additionally, this work reviews the life cycle analysis (LCA) of HVO, providing a comparative assessment of the environmental impacts across the entire value chain, from raw material production to final consumption and also provides a breakdown of the final production costs. The predominant production processes for HVO—namely hydrotreatment, deoxygenation, and isomerization of triglyceride-based biomass—are technologically well-established and widely adopted in the industry. HVO demonstrates a significant reduction in carbon dioxide emissions, ranging from 60 % to 95 % compared to conventional diesel, throughout its entire life cycle. As a result, the application of life cycle analysis methodologies has become increasingly prioritized by companies in this sector to identify additional environmental impacts across various phases of production, distribution, and utilization of this biofuel.

期刊介绍： Biomass & Bioenergy is an international journal publishing original research papers and short communications, review articles and case studies on biological resources, chemical and biological processes, and biomass products for new renewable sources of energy and materials. The scope of the journal extends to the environmental, management and economic aspects of biomass and bioenergy. Key areas covered by the journal: • Biomass: sources, energy crop production processes, genetic improvements, composition. Please note that research on these biomass subjects must be linked directly to bioenergy generation. • Biological Residues: residues/rests from agricultural production, forestry and plantations (palm, sugar etc), processing industries, and municipal sources (MSW). Papers on the use of biomass residues through innovative processes/technological novelty and/or consideration of feedstock/system sustainability (or unsustainability) are welcomed. However waste treatment processes and pollution control or mitigation which are only tangentially related to bioenergy are not in the scope of the journal, as they are more suited to publications in the environmental arena. Papers that describe conventional waste streams (ie well described in existing literature) that do not empirically address ''new'' added value from the process are not suitable for submission to the journal. • Bioenergy Processes: fermentations, thermochemical conversions, liquid and gaseous fuels, and petrochemical substitutes • Bioenergy Utilization: direct combustion, gasification, electricity production, chemical processes, and by-product remediation • Biomass and the Environment: carbon cycle, the net energy efficiency of bioenergy systems, assessment of sustainability, and biodiversity issues.
