Plug Power, a company focussed on providing solutions for the green hydrogen economy, has started operation of the largest liquid green hydrogen plant in the US market.
“This is the largest electrolytic liquid hydrogen production plant, and largest PEM (Proton Exchange Membrane) electrolyser deployment operating in the US,” the company said. The plant showcases Plug’s own electrolyser technology.
Located in Woodbine, Georgia, the plant is designed to produce 15 tons per day (tpd) of liquid electrolytic hydrogen. Through eight 5-megawatt (MW) PEM electrolysers, water is separated into hydrogen and oxygen. The hydrogen gas is then condensed into liquid form at -423ᵒF to be delivered to customers’ hydrogen fuelling stations through Plug’s logistics network using Plug cryogenic trailers.
This new facility will bolster Plug’s supply of liquid hydrogen currently being delivered to Plug’s pedestal customers for material handling operations, fuel cell electric vehicle fleets, and stationary power applications. Liquid hydrogen production, in addition to the on-going gaseous hydrogen production, is expected to positively impact Plug’s bottom line.
“The addition of this liquid green hydrogen production plant to Plug’s electrolyser, fuel cell, and cryogenic equipment manufacturing facilities enables Plug to further its vision for building a vertically integrated green hydrogen ecosystem, a one-stop shop for producing, liquefying, storing, and transporting hydrogen,” a company statement said.
Plug said it finished the plant at a rapid pace of 18 months, more than two times faster than the three-year industry standard for hydrogen plants.
The company has been operating a pilot gaseous hydrogen plant in Georgia using Plug’s 5-MW electrolyser platform for over a year now, supporting high pressure tube trailer filling for Plug as well as other customers. The company is doing substantial work on other US based plants, including plants in Louisiana, New York and Texas.
