本論文は、洋上水素プラントがドイツのエネルギーシステムにとって有利かどうかを調査する。最適化モデルを用いて、洋上水素のLCOHと電力網の制約を変動させながら、洋上水素のシステム価値を評価した。結果、電力網にボトルネックがなく、LCOHが陸上水素より低くない限り、洋上水素は有利ではないことが示された。条件が揃う場合、20〜30GWの最大グリッド容量に対して0.85〜7.91GWの洋上水素プラントが最適となる。

This paper investigates whether offshore hydrogen plants are advantageous for the German energy system compared to offshore power plants. Using an optimization model, it varies the levelized cost of hydrogen (LCOH) and grid capacity limits to assess system value. Results show offshore hydrogen is not advantageous without grid bottlenecks or lower LCOH than onshore hydrogen. Under favorable conditions, 0.85-7.91 GW of offshore hydrogen plants are optimal for grid capacities between 20-30 GW.

📄 Abstract（原文）
We investigate whether offshore hydrogen plants are advantageous for the German energy system compared to offshore power plants. Offshore hydrogen could offer a lower levelized cost of hydrogen (LCOH) than alternative hydrogen supply routes and relieve possible bottlenecks in the electricity grid. However, building offshore hydrogen plants would result in fewer offshore power plants that supply valuable electricity with high full load hours to the energy system. Using an optimization model of the German energy system, we investigate the conditions under which offshore hydrogen plants offer a higher value to the energy system. This is done by varying the LCOH of offshore hydrogen and by limiting the maximum capacity of the electricity grid between the coast and inland. The results show that offshore hydrogen is not advantageous if there is no bottleneck in the electricity grid or if it does not yield lower LCOH than onshore hydrogen. However, if both conditions are met, we find between 0.85 GW and 7.91 GW of offshore hydrogen plants for maximum grid capacities between 20 and 30 GW.
