Regent Seaglider Hybrid Transforms Coastal Transport | 2026 Launch
As coastal communities and island nations grapple with rising transportation demands, Regent’s seaglider emerges as a novel solution blending maritime durability with aviation efficiency. This electric wing-in-ground-effect (WIG) vehicle operates primarily as a boat while harnessing aerodynamic principles typically associated with aircraft. Its unique classification as a Type A WIG craft enables regulatory advantages while challenging traditional definitions of marine and aerial vehicles.
The concept of ground effect vehicles isn’t new – Soviet engineers experimented with massive Ekranoplans in the 1960s. However, Regent’s modern interpretation combines cutting-edge hydrofoil technology with electric propulsion systems. This fusion creates a vessel capable of 180 mph speeds while consuming 50% less energy than conventional aircraft, according to company data. With 600 pre-orders worth $9 billion already secured, the seaglider represents more than technological curiosity – it’s a strategic play in the evolving sustainable transport market.
Regent’s design team faced a critical challenge: creating a vessel that transitions seamlessly from floating to flying. The solution emerged in retractable hydrofoils that lift the 20-meter wingspan craft from water contact during takeoff. Once airborne, the seaglider maintains a 5-10 meter altitude using ground effect – the aerodynamic phenomenon where reduced drag near surfaces enhances lift efficiency.
This three-phase operation (float, foil, fly) requires precise engineering coordination. Marine architects developed a deep V-shaped hull to handle open-water conditions, while aerospace engineers optimized the wing design for maximum ground effect benefit. The result is a vehicle that consumes 0.8 kWh per passenger mile according to Regent’s white papers, comparable to electric buses but at six times the speed.
“It’s truly a boat that flies. Unlike seaplanes with added floats, our design exists natively in both environments,” explains CEO Billy Thalheimer. This philosophy drives the team’s 50/50 split between marine and aerospace engineers.
By classifying as a maritime vessel rather than aircraft, Regent leverages simpler US Coast Guard certification instead of FAA aviation regulations. However, this path introduces unique complexities. The company works with Lloyd’s Register to establish global standards for WIG operations, addressing concerns about wave clearance limits and emergency procedures.
Current prototypes undergo rigorous testing in Narragansett Bay, where engineers validate fail-safe systems for sudden weather changes. “One storm test showed we can maintain flight stability in 4-foot swells,” notes VP of Certification Ted Lester. The team aims for 2026 commercial deployment, with pilot programs planned for Hawaiian island routes and Mediterranean ferry services.
Strategic partnerships accelerate development across multiple fronts. Energy giant TotalEnergies plans seaglider deployments for offshore wind farm crews, potentially replacing helicopter transports. Meanwhile, regional airlines like Mokulele explore coastal route integrations, drawn by the vehicles’ 180-mile range with 12 passengers. The seaglider’s $9 billion order book reveals strong industry confidence, particularly from ferry operators and island nations. Analysts project the WIG market could reach $30 billion annually by 2035, with Regent positioned to capture 60% market share according to Maritime Strategies International.
Upcoming Monarch-class models promise 100-passenger capacity, targeting short-haul routes like Miami-Nassau or Singapore-Johor. This expansion aligns with IMO predictions that 40% of coastal transports under 300 miles could shift to WIG vehicles by 2040, reducing carbon emissions by 85 million tons annually.
“We’re not just building vehicles – we’re creating a new transportation layer between sea and sky,” Thalheimer states, highlighting plans for automated docking systems and renewable energy integration.
The seaglider’s hybrid approach solves multiple transport challenges simultaneously. By merging marine durability with aviation speed, it offers coastal regions a sustainable alternative to carbon-intensive ferries and short-haul flights. Regulatory progress and successful prototype tests suggest this technology will soon transition from concept to operational reality.
Looking ahead, advancements in battery density and autonomous navigation could enable larger 200-passenger models by 2030. As climate policies prioritize maritime decarbonization, WIG vehicles like< Regent's seaglider appear poised to redefine coastal mobility across global markets.

Washington Launches Cascadia Sustainable Aviation Accelerator for SAF
The Cascadia Sustainable Aviation Accelerator launches with $20M funding to boost Pacific Northwest Sustainable Aviation Fuel production to 1 billion gallons annually by 2035.
This article is based on official press releases from Alaska Airlines and Washington State University, as well as public announcements from the launch event.
On January 8, 2026, a coalition of government, industry, and academic leaders officially launched the Cascadia Sustainable Aviation Accelerator (CSAA). Unveiled at the Boeing Future of Flight in Mukilteo, Washington, the initiative aims to establish the Pacific Northwest as a global leader in the production and deployment of Sustainable Aviation Fuel (SAF).
According to official announcements, the accelerator is backed by $20 million in initial funding. This capital includes $10 million from Washington State’s Climate Commitment Act funds and a matching $10 million contribution from an anonymous philanthropic donor. The coalition has set an ambitious target: to scale regional SAF production to 1 billion gallons annually by 2035.
The initiative represents a broad partnership designed to bridge the gap between policy, technology, and commercial viability. Washington Governor Bob Ferguson championed the launch, positioning it as both an economic engine and a critical climate solution for the state.
The coalition features major stakeholders across multiple sectors:
“We have all the pieces in place to ensure this once-in-a-generation economic opportunity is realized, and this accelerator will make that happen.”
, Governor Bob Ferguson, via official press release
To address the complex barriers facing the SAF market, the initiative is divided into two complementary arms: the Accelerator and the Institute.
The CSAA focuses on market acceleration, financing, and policy advocacy. Its primary mission is to “de-risk” the industry for producers and investors. By harmonizing tax incentives and aggregating fuel demand from airlines and corporate partners, the Accelerator aims to create a stable market environment that encourages rapid scaling of production facilities. The Institute will handle the technical and scientific challenges of SAF adoption. It will operate a new Sustainable Aviation Fuel Research and Development Center based at Paine Field in Snohomish County. While a permanent facility is scheduled for completion by 2029, the center will open in a temporary commercial space in the coming months.
A key feature of the Institute will be the world’s first “SAF Repository.” This facility will function similarly to a seed bank, collecting, indexing, and distributing fuel samples to researchers globally to standardize testing and certification processes.
“For aviation to remain strong and resilient in the decades ahead, sustainability must be part of its future.”
, Elizabeth Cantwell, WSU President, via WSU News
Sustainable Aviation Fuel is widely considered the most viable near-term solution for decarbonizing long-haul aviation. Made from feedstocks such as agricultural waste, used cooking oil, or captured carbon, SAF can reduce lifecycle emissions by up to 80% compared to conventional jet fuel. However, current supply accounts for less than 1% of global jet fuel usage, and it remains significantly more expensive than fossil-based alternatives.
The Pacific Northwest is viewed as an ideal “test bed” for solving these problems due to its access to renewable hydroelectric power, forestry and agricultural residues, and a deep aerospace talent pool.
The Accelerator aims to support existing regional projects, including:
“This is a systems issue that no one company can solve. You’ve got great companies… ready to use this fuel, but we have to make it available.”
, Guy Palumbo, Amazon Director of Public Policy, via launch event remarks
The launch of the Cascadia Sustainable Aviation Accelerator marks a shift from individual corporate sustainability goals to a systemic regional strategy. While the target of 1 billion gallons by 2035 is aggressive, the bifurcation of the initiative into an “Accelerator” (finance/policy) and an “Institute” (R&D) suggests a mature understanding of the bottlenecks. The primary challenge for the CSAA will be feedstock logistics. While the Pacific Northwest has abundant forestry and agricultural waste, the infrastructure to collect, transport, and process these materials at a scale capable of producing 1 billion gallons does not yet exist. Furthermore, the involvement of corporate giants like Amazon and Microsoft is critical; their willingness to pay a “green premium” for sustainable air cargo and travel could provide the demand certainty that producers need to secure financing for new plants.
Success will likely depend on how quickly the Institute can streamline the fuel certification process, which has historically been a slow hurdle for new SAF pathways.

Hawaiian and Alaska Airlines Partner for Hawaii SAF Production by 2026
Hawaiian and Alaska Airlines join Par Hawaii and Pono Energy to produce Sustainable Aviation Fuel locally with a $90M refinery upgrade, targeting 2026 deliveries.
This article is based on an official press release from Alaska Airlines and Hawaiian Airlines.
In a significant move toward energy independence and decarbonization, Hawaiian Airlines and Alaska Airlines have announced a strategic partnership with Par Hawaii and Pono Energy to establish the first local supply chain for Sustainable Aviation Fuel (SAF) in Hawaii. According to the joint announcement, the consortium aims to begin deliveries of locally produced SAF by early 2026.
The collaboration brings together the state’s largest energy provider, its primary air carriers, and local agricultural innovators. The project centers on upgrading Par Hawaii’s Kapolei refinery to process renewable feedstocks, specifically Camelina sativa, a cover crop that will be grown on fallow agricultural land across the islands. This “farm-to-flight” ecosystem is designed to reduce the aviation industry’s carbon footprint while diversifying Hawaii’s economy.
The airlines have committed to purchasing the SAF produced, providing the guaranteed demand necessary to make the project commercially viable. This agreement aligns with both carriers’ long-term goals of achieving net-zero carbon emissions by 2040.
Par Hawaii is spearheading the infrastructure development required to make local SAF a reality. According to project details summarized in the announcement and related reports, the company is investing approximately $90 million to upgrade its Kapolei refinery. This facility, the only refinery in the state, will convert a distillate hydrotreater to produce renewable fuels.
The upgraded unit will utilize HEFA (Hydroprocessed Esters and Fatty Acids) technology, a mature method for producing bio-jet fuel. Once operational, the facility is expected to have a significant output capacity.
In a joint statement, the partners emphasized the dual benefits of the initiative:
“This initiative will enable SAF production for more sustainable future flying and deliver economic benefits through the creation of a new energy sector and fuel supply chain in Hawai‘i.”
, Joint Press Statement, Alaska Airlines & Hawaiian Airlines
A critical component of this partnership is the sourcing of sustainable feedstock. Pono Energy, a subsidiary of Pono Pacific, will lead the agricultural operations. The project relies on Camelina sativa, a fast-growing, drought-tolerant oilseed crop that matures in 60 to 75 days. According to Pono Pacific, Camelina is ideal for Hawaii because it can be grown as a cover crop between other food crop rotations. This ensures that fuel production does not displace local food production. The crop helps prevent soil erosion, requires minimal water, and produces a high-protein “seedcake” byproduct that can be used as FDA-approved animal feed for local ranchers.
Chris Bennett, VP of Sustainable Energy Solutions at Pono Pacific, highlighted the circular nature of the project:
“Camelina represents a rare opportunity for Hawai‘i to build a true circular-economy model around renewable fuels.”
, Chris Bennett, Pono Pacific
The project is projected to support approximately 300 high-value manufacturing jobs at the refinery, in addition to creating new agricultural jobs for farming and harvesting. By producing fuel locally, the partnership aims to reduce Hawaii’s extreme dependence on imported fossil fuels, enhancing the state’s energy security.
The Cost and Scale Challenge
While this partnership marks a pivotal step for Hawaii, significant hurdles remain regarding cost and scale. SAF is currently estimated to be two to three times more expensive than conventional jet fuel. Without substantial subsidies or “green premiums” paid by corporate customers or passengers, this price differential poses a challenge for airlines operating in a price-sensitive leisure market like Hawaii.
Furthermore, while the projected 61 million gallons of renewable fuel is a substantial figure, it represents only a fraction of the total jet fuel consumed by commercial aviation in Hawaii. To run the refinery at full capacity, the facility will likely need to supplement local Camelina oil with imported waste oils, such as used cooking oil, until local agricultural production scales up. The success of this initiative will likely depend on the continued support of federal incentives, such as the Inflation Reduction Act, and state-level renewable fuel tax credits.

Frequently Asked Questions
The partners expect the first deliveries of locally produced SAF to begin in early 2026.
Sustainable Aviation Fuel (SAF) is a liquid fuel currently used in commercial aviation which reduces CO2 emissions by up to 80%. It is produced from renewable feedstocks rather than crude oil.
No. The feedstock, Camelina sativa, is grown as a cover crop on fallow land or between food crop rotations, meaning it does not compete with food production.
Par Hawaii is leading the capital investment, estimated at $90 million, to upgrade the Kapolei refinery.

KLM Supports National SAF Fund to Strengthen Dutch Economy
KLM endorses the Wennink report urging a national Sustainable Aviation Fuel fund and €151-187B investment by 2035 to support Dutch economic growth.
On December 12, 2025, KLM Royal Dutch Airlines officially endorsed the findings of the newly released advisory report, “The Route to Future Prosperity” (De weg naar toekomstige welvaart). Authored by former ASML CEO Peter Wennink, the report outlines a strategic roadmap for the Dutch economy, emphasizing the need for significant investment to maintain national competitiveness.
Central to KLM’s endorsement is the report’s recommendation for the Dutch government to establish a national SAF fund. The airline argues that such a financial mechanism is critical to bridging the price gap between fossil kerosene and renewable alternatives, thereby accelerating the aviation sector’s transition to Sustainability without compromising the Netherlands’ economic standing.
Commissioned to analyze the Dutch Investments climate, the Wennink report warns that the Netherlands risks economic stagnation if it does not increase its annual growth rate to between 1.5% and 2%. According to the findings, maintaining current social standards, including healthcare, defense, and the energy transition, requires a massive capital injection.
The report estimates that an additional €151 billion to €187 billion in investment is needed by 2035 to modernize the economy. It identifies specific high-productivity sectors as essential pillars for future prosperity, including Artificial Intelligence, biotechnology, and aviation.
KLM has aligned itself with these findings, noting that a thriving business climate relies heavily on international connectivity. In its statement, the airline emphasized that the connectivity provided by Schiphol Airport is vital for Dutch trade and for attracting international headquarters to the region.
A key pillar of the aviation Strategy proposed in the report is the creation of a government-backed fund dedicated to Sustainable Aviation Fuel. Currently, SAF is significantly more expensive than traditional fossil kerosene, often three to four times the price, and suffers from limited supply availability.
KLM posits that a national fund would act as a catalyst to solve these market inefficiencies. By subsidizing the cost difference, the fund would make SAF more affordable for Airlines, ensuring they remain competitive against non-EU carriers that may not face similar sustainability mandates. Furthermore, the fund is intended to de-risk long-term investments for energy companies, encouraging the construction of domestic refineries, such as the facilities planned in Delfzijl.
“Such a fund would enable the Netherlands to accelerate the production of alternative aviation fuels and make them more affordable, thereby accelerating the sector’s sustainability.”
— KLM Royal Dutch Airlines
KLM used the release of the Wennink report to argue against unilateral national taxes or flight restrictions, which have been subjects of recent political debate in the Netherlands. The airline warns that such measures could harm the Dutch economy by reducing connectivity and driving business elsewhere.
Instead, KLM advocates for incentivizing sustainability. The airline suggests that the government must take a more active role in the energy transition rather than relying solely on industry mandates. According to the press release, “Real progress can only be achieved if government and industry work together and if the government takes a more active role.”
The endorsement of the Wennink report represents a strategic pivot for KLM, moving the conversation from “flight shaming” to economic necessity. By aligning its sustainability goals with the broader “Draghi-style” warnings about European competitiveness, KLM is positioning aviation not just as a transport sector, but as a geopolitical asset essential for the Netherlands’ survival as a trading nation.
However, this call for government funding comes amidst a complex backdrop. In 2024, KLM faced legal scrutiny regarding “greenwashing” allegations, with courts ruling that some “Fly Responsibly” advertisements painted an overly optimistic picture of SAF’s immediate impact. The push for a national fund can be interpreted as a tacit admission that the industry cannot achieve its 2030 and 2050 climate targets through market forces alone; without state intervention to lower the cost of SAF, the “green” transition remains economically unfeasible for legacy carriers.
