"Aviation represents roughly 3.3% of total U.S. greenhouse gas emissions, and jet fuel consumption is forecasted to increase by 2-3% annually through 2050. Sustainable aviation fuel (SAF) is the only viable solution to meaningfully decarbonize our aviation sector in the near-term.
In September 2021, the U.S. established the SAF Grand Challenge, which set a target of three billion and thirty-five billion gallons of annual SAF production in 2030 and 2050, respectively. These targets represent 10% and 100% of projected U.S. jet fuel demand.
Today, announced projects represent over three billion gallons of annual domestic SAF production capacity by 2030, surpassing the U.S. SAF Grand Challenge Target. This announced capacity correlates to over 10% of projected U.S. jet fuel demand, over $44 billion of investment, and over 70,000 jobs across the SAF value chain through 2030." (liftoff.energy.gov).
This report from the U.S. Department of Energy (DOE) explores the obstacles and opportunities surrounding the commercial deployment of SAF. It covers existing technologies, market conditions, strategies for scaling production, critical action items for stakeholders, and progress-tracking metrics.
