Enagás creates a project for the production of water and hydrogen batterieslunes, 24 junio 2019 The Liquefied Natural Gas contained in the Enagás facilities in the Port of Huelva is stored at 160 degrees below zero. If frozen companies require -30º, the question is simple: what can be done with the cold that still remains in that process? The answer, not so obvious, was offered by Javier Ruesga, director of Enagás For Efficiency: to create a process in which water and hydrogen are produced that will be used for vehicle fuel cells and whose only residue in combustion is, again, water.
