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.
Limited supplies of SAF
Demand for SAF continues to grow, yet the aviation industry is challenged by limited supplies of traditional SAF feedstocks such as vegetable oils, animal fats and waste oils. Ethanol offers producers a widely available, economically viable feedstock. Honeywell’s ready-now technology uses high-performance catalysts and heat management capabilities to maximise production efficiency, resulting in a cost-effective, lower carbon intensity aviation fuel.
A 2021 life-cycle analysis by the U.S. 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 pioneered SAF production with its Ecofining™ technology, and our new ethanol-to-jet fuel process builds on that original innovation to support the global aviation sector’s efforts to reduce GHG emissions and meet SAF production targets with an abundant feedstock like ethanol,” said Barry Glickman, vice president and general manager, Honeywell Sustainable Technology Solutions.
“Honeywell’s ethanol-to-jet process, when used as a standalone or when coupled with Honeywell carbon capture technology, is ready now to provide a pathway to lower carbon-intensity SAF.”
SAF plants using Honeywell’s technology can be modularised off site, enabling lower installed costs and faster, less labour-intensive installation compared to job site construction. By utilising 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 maximising use of exiting sites for SAF production to meet the growing market demand.
In 2021, the Biden Administration announced its Sustainable Aviation Fuel (SAF) Grand Challenge for the U.S. 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 U.S. aviation fuel demand with SAF by 2050.
Also in 2021, 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.
