The 'Decarbonizing Aviation and Maritime Industries - 2025' report delves into the challenges faced by the aviation and maritime sectors in reducing emissions, emphasizing the demand for energy-dense and cost-competitive fuels. While sustainable aviation fuels (SAFs) have been a focus, reliance solely on them is unlikely due to feedstock constraints and sustainability issues. The report identifies electrification, alternative fuels, hydrogen, and carbon capture, utilization, and storage (CCUS) as key energy transition technologies with decarbonization potential for both industries. In aviation, weight restrictions and energy density limitations make electrification more feasible for short-range or hybrid solutions. Hydrogen is highlighted as crucial for decarbonizing long-haul flights, albeit hindered by technology delays. Additionally, airlines are exploring carbon removal credits from CCUS vendors to offset emissions. On the other hand, the maritime sector is well-positioned to leverage multiple energy transition technologies, including biofuels, CCUS, and hydrogen. However, challenges exist, such as limited feedstock supply for biofuels and the high cost of adopting advanced technologies. Key highlights from the report include the significant contributions of aviation and maritime to transport emissions, forecasts on SAF production capacity, and the role of hydrogen and CCUS in decarbonization efforts. The analysis also covers global trends in hydrogen and CCUS capacity, emphasizing the growing role of direct air capture technology. By 2030, substantial investments in low-carbon hydrogen production are predicted, particularly for synthetic fuels targeted at the transportation sector. The report underscores the necessity for policy incentives to drive the adoption of decarbonization technologies in both sectors. It outlines challenges such as weight limitations for aircraft in electrification and the high costs associated with advanced technologies in maritime. Overall, the report provides a comprehensive overview of current industry emissions, technology adoption trends, and the macroeconomic challenges faced in achieving decarbonization goals.
