US engineering conglomerate Honeywell has partnered with consulting and engineering company Wood to launch a tech solution for firms developing sustainable aviation fuel (SAF), Honeywell announced on 23 September.

The collaboration will combine Honeywell’s Ecofining production process - which converts waste oil, fat and grease into Honeywell Green Jet Fuel - with Wood’s hydrogen plant technology.

Honeywell said the new method would use Ecofining by-products to create renewable hydrogen, which would then be reintroduced into the company’s production process.

This method would counter existing issues of food impurities found in current samples of SAF, creating a “cleaner burning” fuel, according to the company.

“The combination of these technologies from Honeywell and Wood greatly reduces fossil carbon dioxide emissions compared to traditional fuels by using by-products to provide hydrogen for the Ecofining process,” Honeywell Sustainable Technology Solutions vice president and general manager Ben Owens said.

Honeywell said the new method had the potential to reduce lifecycle greenhouse gas emissions (GHGs) by 100% when specific feedstocks were used.

To date, Honeywell has 22 Ecofining units licensed in nine countries around the world, processing 12 different types of renewable feedstocks.
