Trend: what`s sustainable aviation fuel?
The aviation industry is responsible for a significant portion of global greenhouse gas emissions, and the need for sustainable aviation fuels (SAFs) is becoming increasingly important. SAFs are a promising solution to reduce emissions, but several barriers still exist to their widespread adoption.
Aviation is a critical mode of transportation, facilitating global travel and commerce. However, it is also a significant contributor to greenhouse gas emissions, a primary driver of climate change. In recent years, there has been increasing concern about the impact of aviation emissions, and the aviation industry has been exploring ways to reduce its environmental footprint. One of the most promising solutions is sustainable aviation fuels (SAFs).
SAFs can potentially reduce aviation emissions and improve the sustainability of the aviation industry.
Types of Sustainable Aviation Fuels: SAFs are fuels from renewable sources, such as biomass, waste, or renewable electricity. The most commonly used types of SAFs are; Biofuels: Biofuels are made from renewable biomass sources, such as plant oils, animal fats, and agricultural waste. They can be produced through various processes, including transesterification, hydro treatment, and gasification. Waste-based fuels: Waste-based fuels are made from waste materials, such as municipal solid waste, forestry residues, and agricultural waste. They can be produced through various processes, including gasification and pyrolysis. Synthetic fuels: Synthetic fuels are made from renewable electricity, which is used to produce hydrogen through electrolysis. The hydrogen is then used to produce synthetic liquid fuels, such as e-kerosene and e-diesel.
Benefits of Sustainable Aviation Fuels: SAFs have several benefits, including Reduction in greenhouse gas emissions: SAFs can reduce greenhouse gas emissions by up to 80% compared to conventional jet fuel. Improved air quality: SAFs produce fewer pollutants than traditional jet fuel, which can lead to improved air quality. Energy security: SAFs can reduce the dependence on fossil fuels, enhancing energy security. Challenges of Sustainable Aviation Fuels: Despite the benefits of SAFs, there are several challenges to their widespread adoption, including Cost: The cost of SAFs is currently higher than conventional jet fuel, which makes it difficult for airlines to justify the use of SAFs Availability: The availability of SAFs is limited, which makes it difficult for airlines to use SAFs on a large scale. Thinking infrastructure: The infrastructure required for production, distribution, and use will likely hold the key to long-term safe project success.
