Exhibit 99.2

Plug Power Hosts Analyst Day, Showcasing the World’s First 15TPD Green Hydrogen Plant

LATHAM, N.Y., Aug. 23, 2023 (GLOBENEWSWIRE) -- Plug Power Inc. (NASDAQ: PLUG), a global leader in comprehensive hydrogen solutions for the green hydrogen economy, today will host its Analyst Day showcasing the accomplishments to date of its 15 ton per day (TPD) liquid green hydrogen plant in Camden County, Georgia. Plug will share how the Georgia plant strengthens Plug’s long-term position as the global leader in green hydrogen production and supplier of electrolyzers. The day’s agenda will include a tour of the hydrogen plant.

The event will start with opening remarks by Andy Marsh, CEO of Plug. During the event, Sanjay Shrestha, EVP, GM of Energy Business and Plug’s Chief Strategy Officer, will discuss the benefits and the learnings to date from this plant. The plant was constructed in 12 months and has 40MW of Plug PEM electrolyzers. The plant is grid-connected, which should ensure a steady supply of power that is critical for a liquid hydrogen plant.

The insights Plug gained designing and constructing this plant are expected to result in design optimization and lower capital expenditure for the company’s other plants currently under construction. As the Georgia plant’s hydrogen production ramps up, it is anticipated to improve Plug’s fuel margin meaningfully from Q2 to Q4 2023.

"This is a momentous event. The construction of this plant brings together more than 40 years of expertise in electrolysis, " says Andy Marsh. "This hydrogen plant reinforces Plug’s dominance in green hydrogen. Congratulations to the Plug team for yet another pioneering milestone."

Sanjay Shrestha adds, “The valuable insights gained from our Georgia facility combined with our expanded electrolyzer manufacturing capacity gives Plug an unmatched competitive edge. Plug is excited to showcase the plant that will help ensure demand as customers expedite adoption of green hydrogen and decarbonize multiple different industries.
