低碳燃料：通往净零排放的最后一公里 合成燃料对于航空和航运脱碳的作用

Investment Rating - The report does not explicitly provide an investment rating for the industry Core Insights - Achieving net-zero greenhouse gas emissions by 2050 requires a fundamental transformation of society from a fossil fuel-centric model to a highly renewable and electrified energy system [4][10] - The aviation and shipping sectors are particularly challenging to decarbonize, necessitating the use of low-carbon fuels such as biofuels and synthetic fuels, which have higher energy densities than hydrogen and electricity [4][5] - Deloitte forecasts that CO2 emissions from aviation will stabilize before 2030 and decrease by approximately 75% by 2050, while shipping is expected to achieve nearly net-zero emissions by 2050, with a reduction of 95% [5][52] Summary by Sections 1. Achieving Net-Zero Emissions Requires Significant Low-Carbon Fuels - To limit global warming to 1.5°C, net-zero emissions must be achieved by 2050, necessitating a shift from fossil fuels to renewable and electrified energy systems [13] - Heavy industries and transportation sectors, particularly aviation and shipping, require high energy density fuels, making low-carbon fuels essential [15][16] 2. Last Mile Decarbonization: Aviation and Shipping - Both sectors must transition to lower greenhouse gas emission transport modes and improve operational efficiencies to reduce fuel consumption [25] - Aviation is projected to see a 2.5x increase in total transport volume from 2023 to 2050, driven by economic growth and increased connectivity [27] 2.1 Aviation Decarbonization - Aviation's CO2 emissions are expected to remain stable until 2030 and then drop to 240 million tons by 2050, a 75% reduction from current levels [30][35] - Sustainable aviation fuel (SAF) is projected to account for 70% of aviation energy consumption by 2050, with synthetic kerosene becoming a major low-carbon fuel source [30][35] 2.2 Shipping Decarbonization - Shipping is projected to grow at nearly 2% annually until 2050, with low-carbon fuels like methanol and ammonia expected to account for 70% of fuel consumption by that year [42][46] - The shipping sector's energy intensity is expected to decrease significantly due to efficiency improvements and the adoption of low-carbon fuels [44] 3. Unlocking the Decarbonization Potential of Synthetic Fuels - Synthetic fuels are anticipated to play a crucial role in decarbonizing aviation and shipping, with a projected need for 150 million tons of sustainable hydrogen and 700 million tons of climate-neutral CO2 by 2050 [5][6] - The production of synthetic fuels requires substantial clean electricity, estimated at 10,000 TWh, which exceeds current global renewable energy generation [6][7] 4. Call to Action - Policymakers must create a supportive regulatory framework and provide economic incentives to facilitate the transition to low-carbon fuels [12] - Collaboration among stakeholders, including fuel suppliers, manufacturers, and infrastructure providers, is essential for the successful adoption of synthetic fuels [12][10]
