Hydrogen electrolyzers at a glance

Much attention has been paid to hydrogen and its potential role in combating climate change.  As a result, hydrogen produced through electrolysis of water via electricity obtained from renewable sources (the green hydrogen: GH2) is gaining momentum around the world.


Since large part of the total cost of GH2 production refers to the cost of the electricity needed for the electrolysis process, Brazil takes the lead for having a predominantly renewable electricity matrix (82%, ANEEL-2021), especially due to the great potential for hydroelectric generation (61%, ANEEL-2021), but also due to the increasing share of non-conventional renewable energy sources, represented by wind and solar PV plants.
