Houston—A Washington state public utility has recently purchased an electrolyzer to produce hydrogen using excess hydropower. The Douglas County Public Utility District, in East Wenatchee, Washington, is purchasing a 5-MW Proton Exchange Membrane electrolyzer built by Cummins that it hopes to have operational by late fall or early next year, said utility spokeswoman Megan Vibbert on Aug. 28. Vibbert said the utility plans to either sell the hydrogen or potentially use it as fuel for its vehicle fleet. She said the utility has yet to work out how it will price the green hydrogen. Green hydrogen refers to hydrogen that is produced without any carbon dioxide emissions.
