Abstract

This study compares the techno-economic performance of on-site green hydrogen stations in Germany and Italy, with and without cogeneration from a standalone metal hydride system, respectively case 1 and 2. Results show that the major CAPEX contributors are the electrolyzer, compression system, and MH material, accounting for 51% and 67% of total investment costs for the electrolyzer and the compression – MH system, respectively. Levelized cost of hydrogen for the first case is 18.3 €/kgH₂ (Germany) and 15.06 €/kgH₂ (Italy), while Levelized cost of storage for the standalone MH station is 0.49 €/kWh (Germany) and 0.26 €/kWh (Italy). In the cogeneration scenario, the levelized cost rises to 21.49 €/kgH₂ (Germany) and 17.6 €/kgH₂ (Italy), but selling surplus electricity can reduce it to 3.1 €/kgH₂.
