Advent Technologies Holdings, Inc. (NASDAQ: ADN) (“Advent“ or the “Company”), an innovation-driven leader in the fuel cell and hydrogen technology space, today announced it has signed a Memorandum of Understanding (“MoU”) with Hydrogen Systems, Inc. (“Hydrogen Systems”), a hydrogen energy solutions company based in Riyadh, Saudi Arabia, to provide integrated hydrogen solutions and value-added support to industrial and renewable energy markets in the Middle East.

Under the MoU, Hydrogen Systems aims to utilize a vast number of existing relationships in the telecom and hydrogen energy marketplace in the Kingdom of Saudi Arabia, and elsewhere throughout the Middle East to market, sell, distribute, install and service Advent’s full line of high-temperature proton exchange membrane (“HT-PEM”) fuel cells and hydrogen production products. Simultaneously, Advent and Hydrogen Systems intend to collaborate and explore potential large-scale development opportunities for hydrogen fuel cell power applications across the region.

Advent’s family of products, including the Serene and M-ZERØ® fuel cell systems, realize a significant carbon advantage over conventional diesel remote power generation technology. HT-PEM fuel cells can operate with a range of low or zero-carbon hydrogen fuels and enable more efficient heat management. Such fuel cells can produce power in extreme ambient temperatures (from -40°C to up to +55°C) and conditions such as high air pollution and low humidity, resulting in a longer lifetime and lower total cost of ownership.

Dr. Vasilis Gregoriou, Advent’s Chairman and Chief Executive Officer, stated, “We look forward to a successful partnership with Hydrogen Systems to support the effort in the Middle East to decarbonize faster by adopting hydrogen and HT-PEM fuel cells to replace conventional and polluting energy sources. Hydrogen Systems’ industry knowledge and reach provide an advantage in bringing disruptive, emerging fuel cell solutions to a mature application.”

Sattam Alsuwailem, Chief Executive Officer of Hydrogen Systems, added: “We are excited to have Advent as our new industry partner and truly believe that this new collaboration can play a vital role in speeding up the Middle East’s transition to clean energy technologies. All of us at Hydrogen Systems are connected through a shared mission to continue providing our customers with the most reliable, efficient, and cost-effective hydrogen solutions. We look forward to further strengthening this mission by bringing Advent’s highly differentiated technology to the Middle East market.”
