petrochemical sources) to jet fuel components; Hydroprocessed Esters and Fatty Acids (HEFA-SPK) from
plant and animal oils; Hydroprocessed Fermented Sugars to Synthetic Isoparaffins (HFS-SIP) made by
microbial conversion of sugars to hydrocarbons; FT-SPK with aromatics (FT-SPK/A) from various sources
of renewable biomass such as municipal solid waste, agricultural wastes and forest wastes, wood and
energy crops; and Alcohol-to-Jet Synthetic Paraffinic Kerosene (ATJ-SPK) derived from isobutanol from
multiple feedstocks.
More than a dozen airlines have signed ‘off-take’ agreements (contractual obligation for SAF volume at a
specific price when it’s produced) with producers, but only one of these agreements (United Airlines and
AltAir Fuels) has resulted in commercial-scale, regular production.
To date (mid-2018), only one commercial SAF production facility exists in the world. This facility, owned
by AltAir Fuels in Paramount, California, is a retrofitted petroleum refinery that now makes renewable
diesel and renewable jet fuel from waste oils and animal tallow (HEFA-SPK pathway). While there have
been several SAF demonstration flights throughout the world over the past several years, the fuel for
the majority of these flights has come from ‘batch’ productions and not commercial-scale facilities. In
total, the present-day regular production of SAF worldwide is less than 4 million gallons per year,
compared with 20 billion gallons per year of petroleum jet fuel consumed in the U.S. alone.
Some ‘batch’ scale but semi-regular production in the world comes from Total (headquartered in
France), who convert Brazilian sugarcane to jet fuel for some of Airbus’ factory delivery flights from
Toulouse, France to the purchasing airline’s home airport.
There are several reasons why the AltAir facility in California has reached commercial scale production,
while others have not. The presence of a shuttered refinery 16 miles from LAX helped reduce capital
costs and permitting obstacles. The policy environment for low carbon fuels (largely supported by
California’s Low Carbon Fuel Standard, or LCFS) allowed the producers to capture financial benefits to
bring down the price of renewable diesel (an important co-product with HEFA-based SAF production)
and SAF to a lesser extent, for end users. And finally, the availability of waste oils and feedstocks near a
large population center, combined with a proven fuel conversion technology, allowed the production
facility to succeed. While this is not an exhaustive list of the success factors of this facility, it highlights
the most critical elements, and those that are relevant to our challenges at SEA.
It is the aim of this plan to describe specific strategies Sea-Tac Airport and the Port of Seattle can
implement to help create these same types of stable incentives, policies, feedstock availability,
partnerships, and research and development support to help additional commercial production scale
facilities come on-line. The strategies outlined in this SAF Strategic Plan reflect the most effective
policies and approaches found around the world (e.g. AltAir Fuels in California, Scandinavian airports)
that have helped build or support a SAF market. Specifically, these strategies are designed to work
together to support an aggregated market signal and facilitate the development of a local SAF supply
chain.
