FOR IMMEDIATE RELEASE

FuelCell Energy Announces U.S. Department of Energy Project Award

DANBURY, CT – September 17, 2020 -- FuelCell Energy, Inc. (Nasdaq: FCEL) -- a global leader in fuel cell technology – with a purpose of utilizing its proprietary, state-of-the-art fuel cell platforms to enable a world empowered by clean energy – announces that the Company’s reversible solid oxide project has been selected by the U.S. Department of Energy (DOE) to receive funding support in the amount of $3.0 million. The project focuses on developing performance improvements to advance the commercialization of FuelCell Energy’s reversible solid oxide fuel cell systems. A reversible solid oxide fuel cell (RSOFC) system is a hybrid operation system that performs water electrolysis for the production of hydrogen, stores the hydrogen, and then produces power by using the produced hydrogen.

“This project significantly aids the development of our solid oxide platform as we work to develop our commercial electrolysis and long-duration storage platform,” said Jason Few, Chief Executive Officer, FuelCell Energy, Inc. “There is a growing realization of the need for clean, cost-effective, long-duration energy storage, which is becoming increasingly urgent as more intermittent sources are being added to the electric grid. Building on our expertise in solid oxide fuel cell technology, we are developing innovative long-term storage solutions that address this potential market through the production of hydrogen via electrolysis.”

Mr. Few continued, “Based on reversible solid oxide fuel cell technology, our solution converts intermittent and excess power during periods of low power demand into hydrogen, stores our hydrogen on-site for long periods of time, and then uses this as a fuel source to generate clean power when needed during times of high power demand. This megawatt scalable solution provides long-duration storage, and compares very favorably against other technologies. This program will help us prepare to increase the scale of the technology and demonstrate our efficient hydrogen-based storage.”

The focus of the program is to make improvements to the fundamental repeating components in the RSOFC stack and deliver stack design improvements, particularly in the area of thermal management, while advancing the fuel cell power management technology. This adds to our current funding for existing technology programs for power generation, electrolysis, and storage. These technology programs are expected to accelerate the progress toward commercializing our solid oxide platform in these applications.
