Other methods include pyrolysis, gasification, and fermentation, which can convert waste materials and non-food crops into SAF.
Advancements in conversion technology are also improving the efficiency and cost-effectiveness of SAF production. These include catalysts and refining processes that can convert sustainable feedstocks into high-quality SAF with minimal energy input and waste generation. These advancements are helping to reduce the production costs of SAF and make it more economically viable for widespread adoption.
Collaborations between industry and academia are also playing a crucial role in improving SAF production efficiency. These partnerships allow for the sharing of knowledge, expertise, and resources, which can accelerate the development and commercialization of new SAF production technologies. By working together, industry and academia can overcome technical challenges and drive innovation in SAF production.
Government policies and regulations promoting the use of SAF
Government policies and regulations play a crucial role in promoting the use of SAF in the aviation industry. International agreements and targets for reducing carbon emissions in the aviation sector have created a framework for action and set clear goals for the industry to work towards.
For example, the International Civil Aviation Organization (ICAO) has set a target to achieve carbon-neutral growth from 2020 onwards and to reduce net aviation CO2 emissions by 50% by 2050 compared to 2005 levels. This target has been adopted by many countries and provides a roadmap for the industry to follow.
In addition to targets, governments are also providing incentives and subsidies for SAF production and adoption. These incentives can take the form of tax credits, grants, or loan guarantees, which help offset the higher production costs of SAF and encourage its use by airlines. By providing financial support, governments are helping to create a market for SAF and stimulate investment in production capacity.
Furthermore, carbon pricing and emissions trading schemes can also promote the use of SAF by creating a financial incentive for airlines to reduce their carbon emissions. These schemes put a price on carbon emissions and allow airlines to trade emission allowances, creating a market-based mechanism for reducing emissions. By including aviation in these schemes, governments can encourage airlines to use SAF and reduce their carbon footprint.
SAF adoption by major airlines and airports
Several major airlines and airports have already started using SAF as part of their sustainability initiatives. These initiatives aim to reduce the environmental impact of air travel and contribute to global efforts to combat climate change.
