LIVERMORE, Calif., Sept. 22, 2025 — Advent Technologies Holdings, Inc. (NASDAQ: ADN), an innovation-driven leader in fuel cells and hydrogen technologies, has delivered its next generation, state-of-the-art Honey Badger 50™ (“HB50”) portable power units to the U.S. ARMY.
This milestone achievement comes under the contract titled “Honey Badger Design Lock for Future Adoption” (the “Design Lock Contract”). Advent has designed the HB50 to play a crucial role in supporting the demanding defense mission requirements of the U.S. Army and the other service branches under the U.S. Department of Defense (“DoD”) and U.S. Department of Homeland Security.
The Design Lock Contract is the continuation of a series of past contracts with the DoD. Its primary objective is to make Advent’s proprietary HB50 portable fuel cell system smaller and lighter by integrating the Company’s innovative Ion Pair™ Membrane Electrode Assembly (“MEA”) technology.
The HB50 power system can be fueled by biodegradable methanol, providing near-silent power generation with clean emissions at a fraction of the weight of traditional military grade batteries. This factor is aligned with the DoD’s pursuit of lightweight and highly portable power solutions to seamlessly power radio and satellite communications apparatus, remote surveillance systems, laptops, and other battery charging needs, making it an ideal choice for covert operations.
Gary Herman, Advent’s CEO, commented, “Our first product delivery is a significant achievement for the Company. It establishes Advent’s portable fuel cell products as the leading choice for greater defense applications and sets the stage for higher production volumes. We also believe our portable power technology has more widespread applications in sectors beyond defense such as robotics, agriculture, drones, emergency operations, as well as catering to the needs of leisure and camping enthusiasts in the hospitality industry.”
Dr. Ryan Pavlicek, General Manager of Advent LLC, “We look forward to an expansion of our collaboration with the DoD on the HB50 and other fuel cell powered products. Advent’s Ion Pair technology will set new benchmarks for fuel cell efficiency, longevity, and power density, providing reliable power both practically and sustainably for critical field operations.”
