Key Takeaways

• REGENT Craft successfully demonstrated remote off-grid charging for its Seaglider vessels, enhancing distributed maritime operations.
• The innovative charging system utilizes modular battery storage and high-power hardware, eliminating reliance on conventional grid infrastructure.
• Seagliders can function as mobile energy assets, significantly improving power logistics for expeditionary military operations.

Innovative Demonstration of Remote Charging

REGENT Craft has achieved a significant milestone by demonstrating remote off-grid charging for its Seaglider vessels. This landmark event took place on May 18, 2026, in collaboration with Schneider Electric and World4Solar. The successful demonstration shows that Seagliders can operate effectively in remote and austere environments without the need for established port infrastructures.

The charging system employed for the Seagliders consists of a three-component architecture, which combines modular battery storage, customized high-power charging hardware, and a direct-current coupled setup. This innovative approach bypasses the multiple conversion stages typically required in conventional AC charging systems, resulting in enhanced efficiency and reliability. Schneider Electric played a key role in adapting its high-power charging technology for maritime applications, while World4Solar provided crucial battery storage solutions.

Seagliders are vehicles that utilize a unique flying technique, operating just above the water’s surface, exploiting the aerodynamic effect known as “ground effect.” This allows them to glide efficiently, achieving high speeds with reduced energy expenditure, unlike traditional vessels that need to displace water to move. Additionally, these vehicles are being developed for both commercial use and defense applications, attracting interest from the U.S. Navy among other organizations.

The defense implications of this remote charging capability are significant. Tom Huntley, General Manager of REGENT Defense, noted that power is essential for mission success in contested and austere environments. The ability to deploy Seagliders from various locations while also delivering energy storage capabilities can greatly enhance the operational flexibility for maritime forces. This functionality aligns with the U.S. Marine Corps and Navy’s concept of Expeditionary Advanced Base Operations, which aims for smaller units to function effectively from dispersed locations without the need for extensive logistics support.

Power availability is frequently cited as a critical barrier in expeditionary operations, particularly in remote locations needing to operate essential systems such as communication and medical equipment. Traditionally, these operations depend on diesel generators and fuel supply lines, which can create vulnerabilities. By enabling Seagliders to deliver power directly, the potential exists to change the dynamics of energy logistics in a way that is mere traditional resupply methods cannot achieve.

A more strategic insight from this demonstration is the concept of Seagliders acting as mobile energy resources. A hybrid version of the vessel could carry a power generation system, allowing it to supply electricity directly to areas lacking reliable power, facilitating the establishment of communications networks and support for smaller unmanned systems.

REGENT’s collaborative approach incorporates non-traditional defense contractors, fostering partnerships that leverage advancements in commercial electrification technologies. By using expertise from the industrial and automotive sectors, REGENT addresses critical logistics issues in maritime defense. Co-founder and CEO Billy Thalheimer mentioned that this demonstration illustrates how Seagliders can move beyond reliance on conventional infrastructures while supporting both commercial and military operations.

The company’s strategy aims to create the necessary infrastructure through commercial deployments in ferry routes and coastal logistics. This method not only minimizes risks for defense customers but also allows REGENT to build crucial operational experience and partnerships essential for future defense applications.
