Honeywell’s UOP Ecofining technology has been used for the commercial production of SAF since 2016, by California-based World Energy, which still is the only 100% renewable jet fuel production facility in the world. Now, Honeywell is taking things to the next level, by reducing lifecycle greenhouse gas emissions (GHG) to 100%, compared to petroleum-based fuel.
Until now, the UOP Ecofining process of converting waste oils and fats into green jet fuel achieved an 80% reduction in lifecycle GHG emissions. By partnering with Wood, a specialist in hydrogen production technology, Honeywell intends to further cut GHG, to 100%.
First, the byproducts of the UOP Ecofining process will be used to produce hydrogen, through Wood’s technology, which would then be re-introduced into the SAF-making process, to help reduce fuel impurities. This results not only in cleaner-burning fuel, but also in an additional 10% GHG cut.
Finally, the CO2 that’s generated through the hydrogen production process, is captured and stored underground, which cuts GHG emissions by an extra 10%. In the end, by combining Honeywell’s and Wood’s technologies, an aviation fuel that is completely carbon neutral can be obtained.
This future refinery would be, according to Honeywell, entirely self-sufficient in terms of hydrogen production, while also producing cleaner fuel – which helps support the U.S. government strategy for the large-scale production and use of SAF.
