## Exhibit 99.1

**Exhibit 99.1**

**Advent Technologies Holdings, Inc. Enhances License to Groundbreaking Ion Pair Technology Developed at Los Alamos National Laboratory by Acquiring Exclusivity in Marine, Aviation, and Portable Power Fields**

LIVERMORE, CA - August 12, 2025 - Advent Technologies Holdings, Inc. (NASDAQ: ADN), an innovation-driven company in the fuel cell and hydrogen technology space, announced today that it has entered into a new enhanced license agreement with TRIAD National Security for the Ion Pair technology originally developed at Los Alamos National Laboratory. In the new enhanced license, Advent acquired exclusivity to the technology in the marine, aviation, and portable power fields while retaining its non-exclusive rights in all other fields.

Dr. Emory DeCastro, Advent's Chief Technology Officer, stated: "We are very excited to leverage the Los Alamos technology into areas that will make a real difference in Defense, Homeland Security, marine, and aviation systems. We look forward to working with our partners in implementing this technology. These developments have the potential to bring the advantages of fuel cells to traditionally hard-to-penetrate areas of aviation, marine, and portable power through Ion Pair's higher power density and simplified packaging system."

The license covers the following exclusive fields of use:

**Marine:** Vessel propulsion, marine vessel auxiliary power, and dockside vessel support to provide electrical or thermal, direct or indirect (e.g., charging battery bank) power for propulsion or support of auxiliary operations such as lighting, navigation, communication, climate control, refrigeration, galley operations, hotel loads or standby power for crew and passenger accommodations.

**Aviation:** Fuel cell power systems for aircraft propulsion, auxiliary power units (APU), and ground power units (GPU). Auxiliary servicing functions includes cabin lighting, avionics testing, galley operations, and air conditioning. Fuel cell power systems as GPUs on the airport premise grounds would support aircraft maintenance, pre-flight preparation, and auxiliary servicing functions such as cabin lighting, avionics testing, air conditioning, engine start-up, and battery charging.

**Human Portable Power:** Fuel cell power units having a fuel-free system weight of 160 lbs. (72 Kg.) or less, providing electric power for defense, emergency, or expeditionary operations, remote sensing and field instrumentation, charging of personal electronic devices or mission-critical equipment, or off-grid backup power in austere environments and designed to be carried, worn, or transported by an individual without the aid of a vehicle.

Gary Herman, Advent's Chief Executive Officer, commented: "This expansion of the original non-exclusive, unlimited field of use TRIAD license solidifies our position as the leader in High Temperature PEM technology. We at Advent are committed to bringing the Ion Pair technology to the market. Drawing on our decades of experience, and our close collaboration with Los Alamos National Laboratory, we continue to commercialize Ion Pair membrane electrode assembly (MEA) technology while working closely with our customers. We believe that Ion Pair is the long-awaited critical breakthrough for HTPEM fuel cell technology in the marine, aviation and portable power sectors."
