The transition to sustainable energy sources is essential for achieving decarbonization goals, addressing the urgent need to mitigate climate change, reduce greenhouse gas emissions, and ensure energy security. Moving from conventional fossil fuels to cleaner alternatives not only supports environmental preservation but also fosters economic resilience and drives innovation in energy technologies. Renewable fuels such as Hydrotreated Vegetable Oil (HVO) offer a promising pathway for reducing carbon footprints while maintaining operational performance and meeting evolving regulatory standards. This study evaluates the feasibility of HVO as an immediate and viable alternative to traditional fossil fuels in internal combustion engines. Experimental analyses were conducted to assess key performance indicators, including fuel consumption, engine speed, temperatures, and exhaust emissions. The findings demonstrate HVO’s potential to significantly lower carbon intensity without compromising efficiency. Practical considerations, including handling challenges and logistical implications, are also discussed. This work underscores HVO’s critical role in advancing cleaner energy solutions and its contribution to global sustainability objectives.
