Honeywell and Wood are partnering on a package of technologies that will produce carbon-neutral aviation fuel. The technologies, which are based on Honeywell's UPO Ecofining process technology and Wood's hydrogen plant technology, could reduce lifecycle greenhouse gas emissions by 100% using certain feedstocks when compared to traditional petroleum aviation fuel.The UOP Ecofining process technology converts waste oils, fats, and greases into Honeywell Green Jet Fuel, a drop-in replacement for jet fuel. When using a feedstock such as used cooking oils, lifecycle greenhouse gas emissions can be reduced by 80% compared to conventional jet fuel at this stage.Wood's technology will be integrated to use the byproducts of the UOP Ecofining process technology to produce renewable hydrogen, reducing lifecycle greenhouse gas emissions by a further 10%. This next step in enhancing the Ecofinancing process technology will allow for renewable hydrogen to be injected back into the process, removing feed impurities and creating a cleaner-burning renewable fuel.The carbon dioxide generated from the production of the hydrogen can then be captured and routed for permanent underground sequestration using the Honeywell H2 Solutions technology, reducing lifecycle greenhouse gas emissions by a final 10%."The combination of these technologies from Honeywell and Wood greatly reduces fossil carbon dioxide emissions compared to traditional jet fuels by using byproducts to provide hydrogen for the Ecofining process," explained Ben Owens, vice president and general manager of Honeywell Sustainable Technology Solutions. "As a result, a renewable fuels refinery can be essentially self-sustaining in hydrogen production while reducing the carbon intensity of the renewable fuels to very low levels."The U.S. Department of Energy, the U.S. Department of Transportation, and the U.S. Department of Agriculture, among other agencies, worked together to introduce the Sustainable Aviation Fuel Grand Challenge, with a goal to produce 3 billion gallons per year of sustainable aviation fuel by 2030 in the United States. If those 3 billion gallons of SAF were produced using Honeywell's package of technologies, it could result in the equivalent of 34 million metric tons of cumulative carbon dioxide per year, depending on the oil and fat feedstock mix used.The UOP Ecofining process has been used for commercial production of sustainable aviation fuel since 2016 by World Energy in California. The facility remains the only 100% renewable jet fuel unit in the world. The Ecofining technology is used in most 100%-biofeed units producing renewable diesel and all the licensed renewable jet fuel production in the world today. Honeywell UOP currently has licensed 22 Ecofining units in nine countries around the world, processing 12 different types of renewable feedstocks.
