| 要約: | This study examines the evolving role of canola biofuel in achieving energy security, analyzing its historical significance, current challenges, and prospects. Once a dominant feedstock for biodiesel production in Europe, canola biofuel is facing a decline in relevance due to the emergence of second- and third-generation biofuels, which offer greater economic and environmental advantages. The research highlights key factors influencing this shift, including high production costs, resource-intensive cultivation, and suboptimal life cycle environmental performance. Through correlation and causality analyses, the study finds no definitive relationship between oil prices and the frequency of scientific publications on canola biofuels, suggesting other drivers, such as policy and technological advancements, play a more significant role. Despite its diminishing prominence, canola biofuel retains value in energy diversification and rural agricultural support, due to geographic, policy, and investment constraints. The findings emphasize the need for prioritizing the development of more sustainable and efficient biofuel technologies to address global energy and environmental challenges.
