Advent Technologies Holdings, Inc. (NASDAQ: ADNWW) is a clean‐energy technology company focused on the development and commercialization of advanced polymer electrolyte membrane (PEM) materials, fuel cells and electrolysis systems. Through its operating subsidiary H2Fuel S.A., the company designs and manufactures membrane electrode assemblies (MEAs), high‐performance membranes, catalysts and related components for PEM fuel cells. These products are targeted at a range of applications, including material handling, stationary power generation and telecom backup systems, as well as emerging mobility and hydrogen production markets.
Headquartered in the United States with R&D and production facilities in Europe, Advent Technologies leverages a global footprint to serve customers across North America and the European Union. The company’s research centers in Italy and Greece focus on proprietary high‐temperature membrane technology that enables more efficient operation, reduced system complexity and lower overall costs compared to conventional fuel cell designs. Advent also collaborates with industrial partners, equipment manufacturers and academic institutions to accelerate the adoption of hydrogen and fuel‐cell solutions.
Originally founded as H2Fuel in the late 2000s, the business was reorganized under the Advent Technologies Holdings umbrella and went public via a special purpose acquisition company (SPAC) transaction in 2021. This transition provided the capital necessary to expand manufacturing capacity, scale pilot projects and advance commercial validation of its PEM products. Over time, Advent has signed supply agreements and pilot partnerships in Europe and the U.S., demonstrating its commitment to supporting decarbonization efforts in heavy‐duty and off‐grid power sectors.
Advent Technologies is led by Chief Executive Officer Constantinos “Takis” Demetzos, who co‐founded the original R&D enterprise and brings extensive experience in fuel cell innovation. Under his leadership, the company continues to pursue strategic collaborations and commercialization milestones aimed at establishing a scalable value chain for green hydrogen and fuel cell technologies. By focusing on materials, stack components and system integration, Advent aims to deliver sustainable power solutions that align with global targets for emissions reduction and energy transition.
