This unique testing platform supports the demonstration and test of response F Y 1 9 I M PA C T characteristics of hydrogen production via Researchers at INL are addressing the challenge of how tosteam electrolysis in a manner that can store excess electricity for later use by developing a newprovide important grid services such as electrode material for an electrochemical cell that cannon-spinning power reserves and voltage or efficiently convert excess electricity and water into hydrogen.frequency regulation.When demand for electricity increases, the electrochemical cell is reversible, converting hydrogen back into electricity for the grid. The hydrogen could also be used as fuel for heat, vehicles, or other applications.
