SAF-Specific Questions
T&T: How does Neste see PtL technology fitting into the future of SAF production?
JW: Neste expects that after 2030, industrial-scale vol- umes of PtL can become available. However, it will require time to scale up, and all independent studies indicate that it will be a significantly higher cost to produce than HEFA- based SAF. We see the future growth in the supply of SAF building on the foundation of HEFA-based production with other new technologies, including gasification+synthesis and alcohol-to-jet (ATJ), also playing a role. PtL will also play a big part in the future production of SAF.
T&T: What key partnerships has Neste formed to advance the development of SAF?
JW: No company can do it alone when it comes to energy transition. Neste relies on an ecosystem of partners to deliver sustainable products like SAF; these include customers, technology partners, and industry experts.
Moving toward 100% SAF: Neste has been collaborating with engine manufacturers, airlines, and other partners to test the viability of using 100% SAF in aircraft.
Projects: Airbus, Boeing, and recently Bell Textron made the Bell 505 the world’s first single-engine helicopter to fly on 100% SAF.
From grey to green infrastructure: We used pipelines that previously moved fossil fuels to deliver SAF to SFO. Last June, we delivered one batch of SAF from Texas to LGA New York using the Colonial Pipeline. Examples like these show the potential of leveraging what is often consid- ered ‘grey infrastructure’ to fight climate change.
T&T: What are the research and development initiatives Neste is undertaking to improve the production of SAF?
JW: In addition to the PtL mentioned above, Neste is researching the potential of other sustainable future raw materials, making future renewable products from novel vegetable oils & oil-bearing plants on otherwise unused land, lignocellulosic feedstocks (i.e., agricultural and forestry waste), algae, and municipal solid waste.
T&T: What technological challenges does Neste face in producing SAF?
JW: Neste has been producing SAF since 2011. As it is compatible with the existing energy infrastructure, there are no technological challenges to produce and supply the fuel to the end users, i.e., airlines at airports. However, in- creasing availability to replace fossil jet fuel fully requires a massive investment, a ramp-up in production capacity and an increase in available sustainable feedstocks. This additional investment and feedstock cost means that SAF will be more expensive than fossil jet fuel (with its associ- ated incremental carbon emissions) for some time.
The critical issue is ensuring sustainability and delivering a reduction in net greenhouse gas emissions. Neste has a strict supplier code of conduct, meaning that our suppli- ers should have the same commitment as us: conducting business to protect the environment, biodiversity, and human rights. If a supplier can’t meet this, we don’t do business with them.
