Optimal Sizing of Electrolysis Systems in Regions with Renewable Energy and Limited Transmission Capacity: A Case Study of the Lolland-Falster Islands, Denmark

Published: Jan. 1, 2025

Regional hydrogen production via electrolysis, particularly on islands with abundant renewable energy capacity and constrained transmission infrastructure, provides a complementary pathway to convert excess electricity into hydrogen. This study focuses the Lolland-Falster in Denmark, where projected will include 957 MW of solar photovoltaic, 127 onshore wind, 1186 offshore wind. The is expected be limited 625 by 2026-7, potential increase 1000 subsequent years. results highlight that sales price primary determinant economic viability. Higher prices lead higher levelized cost generated hydrogen, they also drive feasibility through increased output enhanced profitability. Assuming 3.5 €/kg, optimal threshold grid for converting determined 70 €/MWh electrolyzer calculated 1300 1700 MW. Under these conditions, annual benefits are estimated 156 million euros 125 euros, respectively, excluding expansion costs.
