US-based technology company Honeywell has unveiled its new ethanol-to-jet fuel (ETJ) processing technology, which enables the production of sustainable aviation fuel (SAF) from corn-based, cellulosic, or sugar-based ethanol.

The company claims that its ETJ processing technology has the potential to lower greenhouse gas (GHG) emissions by 80% on a total lifecycle basis in comparison to petroleum-based jet fuel, based on the ethanol feedstock utilised.

Honeywell Sustainable Technology Solutions vice-president and general manager Barry Glickman said: “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.

“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.”

The new solution makes use of catalysts and heat management capabilities for optimum production efficiency, which is said to lead to a cost-effective and lower carbon-intensity aviation fuel.

SAF plants that leverage its technology can be modularised off-site, supporting reduced installed costs, stated the firm.

It further noted that with its ETJ technology and an integrated, modular construction approach, new SAF capacity could be built over a year quicker than traditional approaches.

Honeywell’s new technology is also said to support the global drive to meet SAF mandates by the end of this decade.

Last year in November, Honeywell strengthened its Navitas software suite to support airport operators and air navigation service providers.
