This new facility represents a significant investment in Advent's future growth, as it will allow the Company to expand its production capacity and fulfill the rising global demand for electrochemistry components in the clean energy sector. Guests toured Advent's new facility, which has:

• State-of-the-art coating machines that support the seamless transition from prototypes to initial production runs for advanced membranes and electrodes of fuel cells.
• A fully analytical department dedicated to quality control, performance analysis, and improving product lifetime.
• Fuel cell and electrolyzer test stations for statistical process control and development of next-generation membrane electrode assembly (“MEA”) materials.
• An engineering lab for developing automated assembly processes for MEAs and stacks.

In addition, Advent executives and Massachusetts elected officials discussed the future of the State’s clean energy sector and how the U.S. Department of Energy’s Regional Clean Hydrogen Hubs program can accelerate its development. Advent is one of the companies that has co-signed a Memorandum of Understanding with the New York State Energy Research and Development Authority along with more than 60 clean hydrogen ecosystem partners to develop a proposal that will enable the Northeastern United States to become one of at least four regional clean hydrogen hubs.

Advent's new state-of-the-art facility at Hood Park brings together the Company’s corporate office staff, previously located at 200 Clarendon Street in downtown Boston, and its R&D team from Somerville's Greentown Labs. The facility is equipped to manufacture a range of innovative products, including the Ion Pair™ MEA. This next-generation MEA technology aims to revolutionize the global market by enabling fuel cells to have an expected lifetime of at least three times longer and also deliver double the power density of Advent's earlier fuel cell systems, making them ideal for heavy-duty mobility applications.

According to the 2022 Massachusetts Clean Energy Industry Report, the clean energy sector contributed to more than $14.2 billion to Massachusetts' Gross State Product and employed more than 104,000 workers in 2021. Advent’s newly established facility is expected to create employment opportunities for fuel cell engineers and material scientists in Massachusetts and further contribute to the growth of the clean energy sector.

Dr. Vasilis Gregoriou, Advent’s Chairman and Chief Executive Officer, commented, "I would like to express my sincere appreciation to Governor Maura Healey, other elected officials, esteemed guests, and our business partners for joining us at the grand opening of Advent’s new fuel cell R&D and manufacturing facility. Their presence was a testament to the importance of the clean energy industry in Massachusetts and the potential of hydrogen technology. On behalf of the entire Advent team, I would like to thank them for their support and encouragement as we strive to become a leader in the electrochemistry components industry and help accelerate the global transition to a net-zero carbon future."
