- Portuguese and Italian researchers said the LCOH is lower onshore than offshore due to the cost structure and capacity factor.
- PV-wind configurations reduce the LCOH up to 70%
“The averages for Italy and Portugal are respectively €7.25 ($7.78)/kg and €6.85/kg (onshore), €15.81/kg and €10.48/kg (offshore),” said researchers from Portugal and Italy. They added that single configurations obtained LCOH reductions of up to 7% and 11% (offshore) and 29% and 27% (onshore).
“Hybrid onshore configurations, where both solar and wind power plants are connected to the electrolyser, generated the highest reductions in the cost of producing hydrogen—the LCOH decreased as much as 52% in Italy and 70% in Portugal,” the team wrote in “Optimal sizing of renewables-to-hydrogen systems in a suitable-site-selection geospatial framework: The case study of Italy and Portugal,” which was published in Renewable and Sustainable Energy Reviews.
