Middle East hydrogen production could cost less with grid-connected electrolysis

Middle East hydrogen production could benefit from connecting electrolysers to regional power grids rather than relying exclusively on dedicated off-grid renewables. This study models nine interconnected power systems in 2050, comparing green hydrogen, grid-connected electrolysis and blue hydrogen under domestic-oriented and export-oriented production scenarios. Grid-connected electrolysis delivers modelled system-based production costs of $1.90–$2.31/kg, compared with $2.44–$2.78/kg for off-grid green hydrogen. […]
