CHICAGO - United Airlines in Chicago announced that the company wants to turn microalgae into sustainable aviation fuel (SAF) with its investment of $5 million in biofuel company Viridos. The investment was made as part of of its recently-announced UAV Sustainable Flight Fund. This investment will support the production of sustainable aviation fuel (SAF) made from algae, an abundant and scalable resource that can be grown and harvested without impacting the food supply chain.
Viridos specializes in the bioengineering of microalgae and its proprietary technology accelerates the amount of oil that can produced from microalgae. This algae oil could then be used to scale the future production of SAF.
Viridos has already achieved seven times the oil productivity compared to typical wild-type algae. This creates an opportunity for potentially scalable and more sustainable production of algae oil, that could later be used to produce SAF. Based on current estimates, SAF created by Viridos' algae oil is expected to have a 70% reduced carbon footprint on a lifecycle basis when compared to traditional jet fuel.
Viridos' bioengineering technology combines several important and unique attributes contributing to better scalability and sustainability compared with traditional jet fuel production:
- Surface area oil productivities of Viridos algae far exceed any traditional oil crop, achieving high algae oil output on comparatively small areas.
- Algae are grown in vessels containing seawater. This allows contained deployment in hot and dry locations without taxing scarce freshwater and arable land resources, while eliminating runoff.
- Its algae have extremely high oil contents facilitating downstream processing to algae oil.
Viridos algae oil is a quality plant oil allowing existing bio-refineries to process the oil with high yield.
"By establishing production sites to grow Viridos-engineered microalgae in saltwater, we are creating the foundation for a biofuel future that moves away from fossil fuels without competing for precious resources such as fresh water and arable land. We are excited to have the support from United Airlines. Together we can build the ecosystem needed to bring algae biofuels to the market," said Oliver Fetzer, Viridos Chief Executive Officer.
