Plug Power (NASDAQ: PLUG) has recently announced the historic flight of a regional airliner powered by its line of ProGen fuel cells. Led by Universal Hydrogen, the hydrogen fuel cell-powered flying testbed took off at Grant County International Airport in Washington state, marking a significant milestone for both companies.

The 40-passenger airplane's reached an altitude of 3,500 feet during the 15-minute flight. The partnership between Plug Power and Universal Hydrogen is expected to revolutionize the aviation industry, as the two companies work towards converting a 56-passenger ATR 72 regional aircraft to run on hydrogen. 

The success of this flight and the anticipated entry into passenger service in 2025 is a significant milestone for the global green hydrogen economy.

Plug Power CEO Andy Marsh stated: “We’ve long said hydrogen can power applications, such as planes, while reducing toxic carbon emissions. Today, we proved it, and we’re one step closer to a more sustainable future.”

Plug Power is building an end-to-end green hydrogen ecosystem, from production, storage and delivery to energy generation, to help its customers meet their business goals and decarbonize the economy.
