“We are committed to building out hydrogen networks in the United States and Europe,” Andy Marsh, chief executive of Plug Power told me in an interview. “We can generate green hydrogen out of the electrolyzer at $2 per kilogram — similar to grey hydrogen using natural gas. We have developed these products for a decade and are better positioned to know what it costs to build these things.”
"The critical component is the electrolyzer, which creates an electric current that splits the hydrogen and oxygen from water. Plug Power says its electrolyzer and steam methane reforming cost roughly the same. But electrolyzer technologies are advancing while prices are dropping, predicted to be $1.50 per gram soon."
"As for Plug, it has an existing green hydrogen project in Tennessee, capable of producing 20 tons per day. Similar projects will open in 2024 in Louisiana, Texas, and New York State, making 15, 45, and 74 tons daily, respectively. California will open a project in 2025, producing 30 tons daily of green liquid hydrogen."
