ZeaKal today announced that PhotoSeed™ Soy has been validated as the first sustainability-embedded trait technology for agriculture, a technology that could expand the volume of sustainable aviation fuel (SAF) production by approximately one billion additional gallons on existing U.S. soybean acreage.
Han Chen, co-founder and CEO of ZeaKal, says they were able to validate PhotoSeed’s impact on the carbon intensity (CI) score of sustainable aviation fuel (SAF) from soybean oil by using well-respected analytic firm Foxley, LLC, which conducted an independent analysis according to multiple global standards and programs. “The data is also being reviewed by SCS Global Services, a leader in the field of sustainability standards and third-party certification,” said Chen. “The modelling shows that PhotoSeed can reduce SAF CI scores by up to 4.6 points.”
Chen says PhotoSeed enhances photosynthetic capacity, increasing soybean oil by 15% and protein by one point without compromising yield or requiring additional inputs. “At a time when the cost and scale for renewable fuels production still falls short of petrochemicals, we can leverage plant genetics to capture carbon and expand the volume of global oil production without needing new land or infrastructure. ZeaKal’s genetics and agricultural partnerships offer the energy industry economically feasible feedstocks with improved CI features in the production of SAF and other renewable fuels.”
Over the past several years, ZeaKal has built a harmonized supply chain for PhotoSeed soy, which includes Gro Alliance, Nutrien Ag Solutions, and Perdue AgriBusiness. The collaboration enables improved oil and protein production with improved sustainability features for the food and agriculture industry. With growing demand from energy, the initial three-million-acre East Coast footprint is an attractive source for low CI feedstock. PhotoSeed soybeans will be available for the 2026 growing season.
Chen adds that PhotoSeed’s verification as a technology pathway for reducing CI also opens opportunities across the company’s other crop programs, including corn and sugarcane. For ZeaKal’s key crop programs, the company forecasts that the global volume of SAF production could expand to 7.5 billion gallons per year.
