Advent Technologies Participates in Major European Hydrogen Project (IPCEI) “White Dragon” Proposal Submission

“White Dragon” is poised to be an important step in the green energy transition to hydrogen technology

Advent Technologies Holdings, Inc. (NASDAQ: ADN) (“Advent”), an innovation-driven company in the fuel cell and hydrogen technology space, today announced the achievement of an important milestone in the development of hydrogen technologies. Specifically, on Wednesday, May 5, the national proposal for hydrogen technologies "White Dragon" was submitted by a group of the largest energy companies in Greece. The proposal sets forth a future vision for the entire hydrogen value chain and a path to expand its role in the Greek energy system’s reduced carbon goals.

DEPA Commercial will serve as the project coordinator of “White Dragon” and, in collaboration with Advent Technologies, Damco Energy S.A. (Copelouzos Group Company), PPC Greece, The Hellenic Gas Transmission System Operator (“DESFA”) S.A., Hellenic Petroleum, Motor Oil, Corinth Pipeworks, TAP and Terna Energy (together the “consortium”), on May 5, 2021, submitted the consortium’s proposal, a more than 8 billion euro plan for the development of an innovative, integrated green hydrogen project in Greece, to the Greek government and the European Union. The proposal already has the support of the Region of Western Macedonia and the Cluster of Bioeconomy and Environment of Western Macedonia.

The objective of the project is to gradually replace the lignite power plants of Western Macedonia and transition to clean energy production and transmission, with the ultimate goal of fully decarbonizing Greece's energy system. The "White Dragon" project plans to use large-scale renewable electricity to produce green hydrogen by electrolysis in Western Macedonia. This hydrogen would then be stored and, through Advent’s high-temperature fuel cells, supply all of Greece with clean electricity, green energy and heat. Advent’s fuel cells provide a combination of both heat and electrical power, and the heat generated by the project can initially be used in conjunction with the district heating networks of Western Macedonia, and in the future in other applications that require a heating and/or cooling system, such as industrial workings, data centers and greenhouses.

Another primary goal of the "White Dragon" project is the development by the consortium of an integrated Hydrogen Industrial Research Center within the Hydrogen High Technology, Research, Development & Innovation Center that is anticipated to be created in Western Macedonia.

Upgrading the existing energy infrastructure, electricity networks and gas pipelines is particularly important to the continued success of the green energy efforts already underway across the EU. Gas pipelines can be used both for transporting green hydrogen to end users and to indirectly store the hydrogen for future use, with a regulatory framework for Energy Net Metering serving as a transition option until the full infrastructure required by the hydrogen economy is built out. To accelerate this development, under "White Dragon," the study and construction of a dedicated hydrogen pipeline in Greece would commence, as would plans to implement the first widescale hydrogen fueled projects for the entire transportation sector, which includes heavy duty trucks, trains and cars. A corresponding infrastructure for hydrogen refueling stations (HRS) and the transportation and distribution of hydrogen over the area’s roads and highways are planned to facilitate the project’s end goals. The dedicated hydrogen pipeline would link green hydrogen production with large hydrogen end users, such as refineries and the fertilizer industries, and will drive their efforts to make their production processes greener. Finally, through the integrated "White Dragon" project, the international transportation and export of hydrogen through the TAP Interstate Pipeline from Greece to Italy is expected to be explored as a future potential goal.

The combined budget for the project, if approved in its entirety by the European and Greek authorities, is €8.063 billion.

• Project duration: 2022 - 2029 (R&D, FID and EET phases)
• Anticipated Hydrogen production: 250,000 tons / year*
• Anticipated Hydrogen for other uses: 58,000 to 71,000 tons / year
• Anticipated CO2 savings: 11.5 million tons / year
• Anticipated Job creation: 18,000 direct jobs and 29,500 indirect

* Renewable hydrogen will be channeled almost entirely into pipelines.

Dr. Vasilis Gregoriou, Advent Chairman and CEO, stated that “The approval of the ‘White Dragon’ project would be an important step for the creation and development of clean energy hydrogen technologies in Greece. We are excited to participate as the fuel cell partner in the submission of such a large-scale project. This is a long-term venture that, although still in the submission phase and awaiting multiple levels of approval, presents exciting possibilities for the future. Its successful implementation could be the key that unlocks the transition to greener power creation and transmission across Greece and potentially, the EU.”
