Plug Power starts production of liquid hydrogen at its existing Tennessee plant

| By Mary Bailey

Plug Power Inc. (Latham, N.Y.) has re-started operation of its hydrogen plant in Charleston, Tennessee, adding about ten tons per day (TPD) of liquid hydrogen supply back onto the U.S. market. Plug also implemented design improvements to enhance overall plant efficiency.

Plug’s cryogenic trailer fleet will deliver liquid hydrogen from the Tennessee plant to Plug’s pedestal customers throughout North America, with a high-density of users clustered throughout the Midwest and along the East Coast. This adds to Plug’s supply of liquid hydrogen currently being delivered to customers for use in material handling operations, fuel cell electric vehicle fleets, and stationary power applications.

“With the Tennessee plant coming back online, we have taken another step towards building a vertically integrated hydrogen network in North America,” said Andy Marsh, Plug Power CEO. “In addition, we expect to have our joint venture plant in Louisiana to come online in the third quarter of 2024, adding another 15 TPD of liquid hydrogen capacity to the market.”

“This liquid hydrogen production out of Georgia and Tennessee is expected to bring down the average cost of delivered hydrogen, positively impacting Plug’s fuel margins in line with our strategy,” added Sanjay Shrestha, General Manager, Energy Solutions & Chief Strategy Officer at Plug.

Plug began production of liquid green hydrogen at its Georgia plant on January 23, 2024. At 15 TPD, this is the largest liquid green hydrogen plant in the U.S. market, and largest PEM electrolyzer deployment operating in the U.S. The company is doing substantial work on building plants in New York and Texas, as well as Europe, with plants underway in Finland and Belgium.
