Techno-economical feasibility to supply CO2 free hydrogen to Germany from Patagonia using wind energy and electrolysis

"The transition to renewable energy sources is reshaping energy systems globally. Germany is a leading example of this shift, having significantly increased its renewable energies (RE) generation in recent years, particularly wind and photovoltaic (PV). However, integrating RE into the grid pre...
