Hawaiian Airlines Inc, the largest and longest-serving air carrier in the US State of Hawaii has announced that it has reached an agreement with compatriot biofuels- and biochemicals producer and process developer Gevo, Inc., to purchase 50 million gallons (≈ 189.25 million litres) of sustainable aviation fuel (SAF) over five years.

According to a statement, Gevo expects to supply the SAF from a facility to be constructed in the Midwestern United States and begin deliveries to Hawaiian’s gateway cities in California (CA) starting in 2029.

The fuel sales agreement is subject to certain conditions precedent, including Gevo developing, financing, and constructing the facility to produce the SAF contemplated by the agreement.

This offtake agreement gets us one step closer to achieving our goal of net-zero carbon emissions by 2050. We intend to continue to invest in SAF, which will be pivotal in reducing our impact on the environment, said Peter Ingram, President and CEO of Hawaiian Airlines.

Low carbon intensity SAF

Gevo will produce SAF using residual starch from inedible field corn, grown using regenerative farming practices.

The production process also will utilize renewable electricity and renewable natural gas (RNG), resulting in low-carbon fuels with substantially reduced carbon intensity – the level of greenhouse gas (GHG) emissions compared to standard petroleum fossil-based fuels across their life cycle.

Gevo is pleased to welcome Hawaiian Airlines to our customer family of airlines that are working hard to achieve their net zero goals. By counting all of the carbon, analyzed using Argonne’s GREET (Greenhouse Gases, Regulated Emissions, and Energy Use in Transportation) method, we are working to help airlines realize these goals, said Dr Patrick Gruber, CEO at Gevo.

Argonne National Laboratory’s GREET model measures the GHG life cycle impacts of fuels, from feedstock to production through combustion.

Gevo’s process is designed to maximize value and minimize waste by using the same acre of farmland to produce both animal feed and renewable fuels while sequestering atmospheric carbon through photosynthesis.

Hawaiian has launched several sustainability initiatives in recent years including a partnership with Par Hawaii, the state’s largest provider of energy products, to study the commercial viability of producing SAF in Hawaiʻi.
