Green hydrogen will be an essential part of the future 100% sustainable energy and industry system. Up to one-third of the required solar and wind electricity would eventually be used for water electrolysis to produce hydrogen, increasing the cumulative electrolyzer capacity to about 17 TWel by 2050. The key method applied in this research is a learning curve approach for the key technologies, i.e., solar photovoltaics (PV) and water electrolyzers, and levelized cost of hydrogen (LCOH). Sensitivities for the hydrogen demand and various input parameters are considered. Electrolyzer capital expenditure (CAPEX) for a large utility-scale system is expected to decrease from the current 400 €/kWel to 240 €/kWel by 2030 and to 80 €/kWel by 2050. With the continuing solar PV cost decrease, this will lead to an LCOH decrease from the current 31–81 €/MWhH2,LHV (1.0–2.7 €/kgH2) to 20–54 €/MWhH2,LHV (0.7–1.8 €/kgH2) by 2030 and 10–27 €/MWhH2,LHV (0.3–0.9 €/kgH2) by 2050, depending on the location. The share of PV electricity cost in the LCOH will increase from the current 63% to 74% by 2050.

太阳能氢气的真实成本

绿色氢将成为未来 100% 可持续能源和工业体系的重要组成部分。高达三分之一所需的太阳能和风能最终将用于水电解生产氢气,到2050 年,累积电解槽容量将增加到约 17 TW el 。本研究中应用的关键方法是学习曲线法关键技术,即太阳能光伏(PV)和水电解槽,以及氢气的平准化成本(LCOH)。考虑了对氢气需求和各种输入参数的敏感性。到 2030 年,大型公用事业规模系统的电解池资本支出 (CAPEX) 预计将从当前的 400 欧元/kW el降至 240 欧元/kW el和 80 欧元/kW el到 2050 年。随着太阳能光伏成本的持续下降,这将导致 LCOH 从目前的 31–81 欧元/MWh H2,LHV (1.0–2.7 €/kg H2 ) 降至 20–54 €/MWh H2,LHV (到 2030 年为 0.7–1.8 欧元/千克氢气),到 2050 年为 10–27 欧元/兆瓦时氢气,LHV(0.3–0.9 欧元/千克氢气),具体取决于地点。到 2050 年,光伏电力成本在 LCOH 中的份额将从目前的 63% 增加到 74%。
