On Monday October 10th, Honeywell announced a new ethanol-to-jet fuel (ETJ) processing technology that allows producers to convert corn-based, cellulosic, or sugar-based ethanol into sustainable aviation fuel (SAF). Depending on the type of ethanol feedstock used, jet fuel produced from Honeywell’s ethanol-to-jet fuel process can reduce greenhouse gas (GHG) emissions by 80% on a total lifecycle basis, compared to petroleum-based jet fuel (based on the Environmental Protection Agency’s summary Life-Cycle Assessment of Green House Gas (GHG) emissions for sugarcane).
In 2021, the Biden Administration announced its Sustainable Aviation Fuel (SAF) Grand Challenge for the US aviation fuel supply sector to produce at least three billion gallons of SAF per year by 2030 and reduce emissions from aviation by 20%, with an eventual goal of meeting 100% of US aviation fuel demand with SAF by 2050.
Thew ethanol-to-jet fuel process supports the global aviation sector’s efforts to reduce GHG emissions and meet SAF production targets.

The same year, the European Council released its ‘Fit for 55’ package which aims to increase the share of sustainable fuels at EU airports from a minimum of 2% in 2025 to at least 63% by 2050. These and other incentives, including the Inflation Reduction Act, accelerate the need for alternative SAF feedstocks to meet demand.
Demand for SAF continues to grow but supplies of traditional SAF feedstocks such as vegetable oils, animal fats and waste oils are, for the time being, somewhat limited. Ethanol offers producers a widely available, economically viable feedstock. Honeywell’s ready now technology uses high-performance catalysts and heat management capabilities to maximize production efficiency, resulting in a cost-effective, lower carbon intensity aviation fuel.
A 2021 life-cycle analysis by the US Department of Energy’s (DOE) Argonne National Laboratory concluded that ethanol-to-jet fuel conversion, combined with other technologies such as carbon capture and sequestration (CCUS) and smart farming practices, can result in negative GHG emissions compared to petroleum-based jet fuel.
Honeywell’s ethanol-to-jet process is ready now to provide a pathway to lower carbon-intensity SAF.

SAF plants using Honeywell’s technology can be modularized off site enabling lower installed costs and faster, less labor-intensive installation compared to job site construction. By utilizing Honeywell’s ETJ technology and an integrated, modular construction approach, producers can build new SAF capacity more than a year faster than is possible with traditional construction approaches.
Petroleum refiners and transportation fuel producers can also benefit from Honeywell’s ETJ design that is purpose-built to enable conversion of current or idle facilities into SAF production plants, potentially maximizing use of exiting sites for SAF production to meet the growing market demand.
