(73b) Navigating Development of Lower Emission Fuels for Marine Decarbonization

Lower emission fuels (LEFs) are pivotal in reducing the carbon emissions of hard-to-abate sectors, particularly marine transportation. In 2018, international shipping accounted for about 3% of global energy-related CO₂ equivalent emissions (~1 Billion Tons CO₂)[1]. Technological innovation, pathway agnostic supportive policies, and collaboration across the value chains are needed to lower the cost to society and drive global adoption of advanced biofuels and synthetic fuels for oceangoing vessels.

Commercializing LEF projects necessitates consideration of various factors including cost competitiveness, scalability, carbon intensity reduction potential, and technology readiness. Once developed, these fuels must be delivered to the market, leveraging logistical systems such as existing pipelines and terminals. Collaborative efforts across multiple stakeholders are thus essential for successful delivery. Chemical and process engineers are well-equipped to lead this transition.
