Hawaiian Airlines Electrifies 73% of Honolulu Ground Fleet with Electric Vehicles
Hawaiian Airlines replaces 116 diesel and propane ground vehicles with electric models at Honolulu airport, supported by Hawaii DOT’s charging infrastructure.

This article is based on an official press release from Hawaiian Airlines.
On May 18, 2026, Hawaiian Airlines announced a significant milestone in its environmental strategy by unveiling a new fleet of fully electric ground support equipment (GSE) at the Daniel K. Inouye International Airport in Honolulu (HNL). According to the official press release, the carrier is replacing 116 legacy diesel and propane-powered vehicles with lithium battery-powered alternatives.
This transition marks a major operational shift at Hawaiian’s primary hub. By eliminating the fossil fuel consumption, fumes, and noise associated with the older vehicles, the airline aims to reduce its greenhouse gas emissions while lowering ongoing maintenance costs.
The initiative was made possible through a strategic infrastructure partnerships with the State of Hawaiʻi Department of Transportation (HDOT), which has heavily invested in the charging network required to support such a large-scale deployment.
Scaling Up Electric Ground Operations
Equipment and Daily Impact
The newly deployed electric fleet replaces 116 baggage tractors, belt loaders, and aircraft pushback tractors. With this rollout, lithium battery-powered GSE now constitutes 73% of Hawaiian Airlines’ total ground support fleet at the Honolulu hub, according to the company’s announcement.
These vehicles are critical to daily operations. The press release notes that the equipment will be utilized by hundreds of ramp workers who process more than 8,500 checked bags daily and support approximately 180 daily flight arrivals and departures at HNL.
Following extensive testing and feedback from its ramp teams, Hawaiian Airlines selected specific models to meet its operational demands. The new fleet includes Charlatte T137 baggage tractors, Charlatte CBL2000 belt loaders, and Kalmar TBL100 towbarless pushback tractors. Notably, Charlatte engineers custom-modified the belt loaders to enhance their versatility, enabling them to service both narrow-body and wide-body aircraft in Hawaiian’s fleet.
Enhancing Ramp Worker Safety
Beyond environmental benefits, the transition introduces several features designed to improve the working environment for ramp employees. The new baggage tractors feature a redesigned cab configuration that protects operators from sun, wind, and rain. Additionally, the electric belt loaders are equipped with an advanced, sensor-guided aircraft approach system designed to prevent collisions and enhance safety during loading procedures.
Infrastructure and State Partnerships
HDOT’s Crucial Investment
The electrification of Hawaiian’s ground fleet relies heavily on infrastructure investments from the State of Hawaiʻi Department of Transportation. According to the provided research report, HDOT has already installed 30 GSE charging stations, which provide 60 charging ports across multiple locations at the Honolulu airport.
Expansion of this network is already underway. An additional four charging stations, yielding eight more ports, are currently under construction and are expected to be operational by the fourth quarter of 2026. To incentivize the adoption of sustainable practices, HDOT is providing Hawaiian Airlines and other airline partners access to these charging stations at no cost for two years.
Ryan Spies, Managing Director of Sustainability for Alaska Airlines and Hawaiian Airlines, highlighted the importance of this collaboration in the company’s official statement:
“Electrifying our ground support fleet in Honolulu, our second-largest hub, represents an important step in our long-term sustainability strategy. By investing in cleaner, quieter and more efficient equipment, we’re reducing our environmental impact, enabling safe and reliable operations, and improving the workplace for our teams and the travel experience for our guests. We extend a big mahalo to the state of Hawaiʻi Department of Transportation for their partnership and investment in the GSE charging infrastructure at Honolulu’s airport.”
Broader Sustainability Context
AirPro News analysis
We view this announcement as a key indicator of Hawaiian Airlines’ accelerated environmental initiatives following its integration into the Alaska Air Group. With Ryan Spies overseeing sustainability for both carriers, this massive fleet overhaul aligns seamlessly with Alaska Air Group’s broader corporate goals, which include achieving net-zero carbon emissions.
This move also reflects a wider, airport-wide sustainability push at Daniel K. Inouye International Airport. Previously, the airport partnered with Sustainability Partners to implement Webasto PosiCharge systems for ground equipment. Delta Airlines was the first carrier to adopt that initial system, reporting estimated monthly savings of $25,000 in diesel and propane costs. Hawaiian Airlines’ deployment of 116 vehicles represents a massive scaling up of this green initiative at HNL.
Furthermore, Hawaiian’s sustainability efforts extend beyond ground operations. The airline has been actively exploring Sustainable Aviation Fuel (SAF) in partnership with local refinery Par Hawaii. The long-term goal of this partnership is to produce SAF locally, eventually replacing up to 25% of Hawaiian Airlines’ fuel demand for island flights, which would help buffer the state from fluctuating imported crude-oil prices.

SABA Members Back Infinium eSAF Facility With Long-Term Deals
Google, McKinsey, and others sign binding SAFc agreements to support Infinium Energy’s 100,000 MT/year Texas eSAF project.

Corporate members of the Sustainable Aviation Buyers Alliance (SABA) have signed binding, multi-year agreements to purchase sustainable aviation fuel certificates (SAFc) from Infinium Energy’s planned electro-sustainable aviation fuel (eSAF) facility in Texas. The commitments, announced on September 22, 2026, are designed to provide the financial demand signals necessary for Infinium to reach a final investment decision on the project.
In a press release issued by SABA, the organization confirmed that American Airlines (AA) will serve as the physical offtaker for the fuel, managing logistics and delivery. The corporate buyers purchasing the associated certificates include AVEVA, Bain & Company, Google, and McKinsey & Company. The agreement marks the first time SABA’s procurement model has been utilized to directly drive new production capacity for scalable sustainable aviation fuel.
Project Atlas production and environmental targets
Infinium Energy was selected through a SABA procurement process earlier in 2026 to provide ultra-low carbon eSAF. The fuel is produced using waste carbon dioxide and renewable energy, distinguishing it from traditional biofuel pathways that rely on agricultural or waste feedstocks.
The planned Texas facility, designated Project Atlas, is expected to have an annual sustainable aviation fuel (SAF) production capacity of 100,000 metric tons. According to the alliance, the contracted volumes will support an expected greenhouse gas abatement of 212,000 metric tons of carbon dioxide equivalent (mtCO2e). SABA equates this emissions reduction to approximately 3,500 commercial flights between John F. Kennedy International Airport (JFK) and Los Angeles International Airport (LAX).
“We’re proud to partner with SABA members including AVEVA, Bain & Company, Google, McKinsey, and others, as well as American Airlines to bring Infinium Energy’s next world scale eSAF facility to life. Their commitment reflects a shared conviction that decarbonizing aviation requires real investment in next-generation supply,” said Robert Schuetzle, CEO of Infinium Energy.
Aggregating demand through book-and-claim
The transaction utilizes a book-and-claim model. Corporate buyers purchase the SAFc to claim the environmental benefits against their business travel emissions, while the physical fuel is delivered to partner airlines. This mechanism allows corporations to fund SAF production even when the physical fuel cannot be delivered directly to the airports their employees use.
American Airlines will manage the physical integration of the eSAF into the commercial aviation fuel supply chain. Jill Blickstein, Chief Sustainability Officer at American Airlines, stated that the corporate commitments broaden participation in the SAF market and demonstrate how customers can collaborate with airlines and fuel producers to advance decarbonization.
SABA, a joint initiative of the Environmental Defense Fund (EDF), the Center for Green Market Activation (GMA), and RMI, has aggregated $500 million in SAFc demand from 35 companies to date. Aviation currently accounts for approximately 2 to 3 percent of global greenhouse gas emissions.
“Novel technologies are critical to meeting future demand for sustainable aviation fuel, but they will not be operational in time without investments made today. This procurement demonstrates how aggregated, long-term demand can help take promising eSAF projects from idea to reality,” said Jon Creyts, CEO of RMI.
AirPro News analysis
We view this agreement as a critical structural step for the eSAF market. Power-to-Liquid (PtL) fuels like those planned for Project Atlas face a steep commercialization barrier. They are highly capital-intensive to build and currently produce fuel at a significant cost premium compared to both conventional Jet A and HEFA-based SAF derived from waste fats and oils.
Airlines operate on thin margins and generally cannot absorb the full green premium of eSAF alone. By unbundling the environmental attributes from the physical fuel, the SABA model allows highly capitalized corporate entities like Google and McKinsey & Company to absorb that premium. More importantly, signing binding, multi-year offtake agreements provides the revenue certainty that infrastructure lenders require before financing first-of-a-kind industrial facilities. If Project Atlas reaches a positive final investment decision based on these contracts, it will validate the book-and-claim model as a viable financing mechanism for next-generation aerospace infrastructure.

EU Exceeds 2025 SAF Mandate at 2.79 Percent Blend Rate
EASA reports EU airports hit 2.79% SAF blend in 2025, surpassing the 2% ReFuelEU mandate with 1.1M tonnes supplied.

The European Union surpassed its initial Sustainable Aviation Fuel (SAF) mandate in 2025, with SAF accounting for 2.79 percent of all jet fuel supplied to EU airports during the first mandatory reporting year.
According to the 2026 ReFuelEU Aviation Annual Technical Report published by the European Union Aviation Safety Agency (EASA) on September 17, 2026, fuel suppliers delivered 1.1 million tonnes of SAF against a total aviation fuel supply of 39.3 million tonnes. The 2.79 percent blend rate comfortably exceeded the 2 percent minimum required by the ReFuelEU regulation for 2025. This uptake resulted in an estimated reduction of 3.77 million tonnes of CO2 equivalent greenhouse gas emissions.
“We are pleased to confirm that the SAF mandate under ReFuelEU Aviation was not only met but exceeded,” EASA Executive Director Florian Guillermet stated in the agency’s press release.
Compliance and distribution across European hubs
The EASA report indicates high compliance rates across the sector. Ninety-three percent of aircraft operators and 90 percent of fuel suppliers fulfilled their reporting obligations in 2025. EASA noted that noncompliance among aircraft operators was primarily limited to small business jet operators, nonscheduled carriers, and third-country operators that failed to respond to competent authorities.
SAF distribution reached 121 Airports across all 27 Member States, representing 79 percent of all Union airports. Uptake was heavily concentrated at major European hubs. Amsterdam Airport Schiphol (AMS) accounted for 29 percent of the tracked SAF supply, followed by Frankfurt Airport (FRA) at 8 percent and Paris Charles de Gaulle Airport (CDG) at 7 percent.
Supply chain dynamics and feedstock dependencies
While the headline blending figures demonstrate regulatory success, the technical report reveals a structural reliance on imported raw materials. Although 86 percent of the SAF supplied at EU airports was refined domestically within the European Union, 85 percent of the underlying feedstocks originated from outside the bloc.
The primary feedstock utilized was Used Cooking Oil (UCO) processed via the Hydroprocessed Esters and Fatty Acids (HEFA) pathway. Of the imported feedstocks, 61 percent originated from China, with additional volumes sourced from Malaysia and Indonesia. On the refining side, Neste’s Rotterdam facility alone produced 33 percent of all European SAF in 2025.
AirPro News analysis
The successful implementation of the 2 percent mandate in 2025 proves that the logistical framework for SAF distribution at major European hubs is functional. However, the heavy reliance on Asian Used Cooking Oil presents a long-term vulnerability for European aviation. As the ReFuelEU mandate scales to 6 percent in 2030, the Regulations will also introduce sub-mandates for synthetic aviation fuels (e-fuels). With approximately 50 synthetic fuel projects awaiting final investment decisions and no large-scale e-fuel facilities currently operational in Europe, we anticipate significant capital mobilization will be required over the next 36 months to prevent future supply bottlenecks and reduce dependency on imported biomass.

Montana Renewables Cuts SAF Expansion Cost to $137M
Calumet’s Montana Renewables targets 200M gallons of SAF annually by 2028 for $137M, down from a $1.2B plan.

Calumet, Inc. and its subsidiary Montana Renewables, LLC announced a revised expansion plan on September 1, 2026, that will scale SAF production to 200 million gallons annually by 2028 for a fraction of the originally projected cost.
By repurposing existing refining equipment at the Great Falls, Montana facility, the company expects to complete the MaxSAF project with only $137 million in remaining capital. This abandons a previous $1.2 billion megaproject design. The pivot eliminates the need for third-party equity and minimizes debt while accelerating domestic sustainable aviation fuel (SAF) capacity.
Capital efficiency and Department of Energy funding
The original Phase 2 plan contemplated $1.2 billion in capital expenditure. The revised strategy captures 70 percent of the expected benefit for 15 percent of the cost. The financial restructuring involves an amended Loan Guarantee Agreement (LGA) with the U.S. Department of Energy (DOE).
The original LGA was executed in January 2025, with a $782 million first tranche funded in February 2025 to recapitalize Montana Renewables, LLC (MRL). Under the amended agreement, the company will make a final draw of $34 million. This is significantly lower than the original $658 million Phase 2 DOE funding limit.
Calumet CEO Todd Borgmann stated the Office of Energy Dominance Financing (EDF) supported the adjustment to the loan agreement.
“Our amended agreement with the DOE facilitates innovative technology and domestic energy security at a fraction of the original cost. EDF’s willingness to right-size the LGA reflects its ongoing support for Montana’s largest agricultural investment. We look forward to our continued collaboration with the DOE on the success of this project,” Borgmann said.
Borgmann credited the company’s engineering and operational teams for developing a project that maximizes output while drastically reducing the required capital investment.
Production timeline and capacity milestones
The Great Falls facility currently operates at a 60 million gallon SAF run-rate following a spring 2026 constraint removal. A scheduled turnaround in the fourth quarter of 2026 will tie in repurposed equipment from the adjacent Calumet Montana Refining facility.
Following the fourth-quarter integration, the company expects to exceed an 80 million gallon SAF run-rate by December 31, 2026. Production is projected to surpass 120 million gallons by spring 2027 and reach the 200 million gallon target by December 31, 2028.
Total renewable product sales, including renewable diesel and renewable gasoline, are targeted at 17,000 barrels per day by year-end 2028. This represents a 40 percent expansion. The expanded facility will consume 2 billion pounds of ranch- and farm-originated feedstocks annually.
AirPro News analysis
The revised MaxSAF expansion highlights a strategic shift in how producers approach SAF scaling. As noted by Aviation Week on September 2, 2026, the plan allows the largest US producer of SAF to more than triple its production capacity for barely 10 percent of the originally planned investment.
During Calumet’s second-quarter 2026 earnings call on August 7, 2026, the company confirmed that Montana Renewables completed performance testing of the newly installed MaxSAF catalyst, which met or exceeded expectations. By leveraging existing fossil-fuel infrastructure rather than pursuing multi-billion-dollar greenfield projects, producers can bring SAF to market faster and with significantly lower financial risk. This capital-efficient model may set a precedent for other refiners looking to enter or expand in the renewable fuels sector without diluting equity or taking on unsustainable debt.
