摘要

绿色氢是替代化石燃料的好选择。利用可再生能源进行水电解，促进脱碳。在巴西东北部条件下，对定日镜和光伏板太阳能驱动的固体氧化物电解电解槽系统进行了技术经济研究。进行了电池模型的建立、太阳能场的设计和光伏电池系统的设计。该系统由60个模块组成，产生112.8 kg/h的绿色氢。该电池在950°C下工作，电流密度为2500 a /m2，效率为95.33%。该模型的相对误差最高，为2.76%。能态电压是电池的主导电压，其次是欧姆过电位。光伏板和电池的平均效率为18.02%。太阳能场的平均效率为34.6%。太阳能领域和光伏/电池组分别占全球成本的42.52%和39.65%。LCOH计算为9.43美元/公斤。给出了接收机和发射塔直径以及LCOH上电池寿命的灵敏度分析。建议进一步研究。

Model, energy and economic analyses of solid oxide electrolysis cells for clean hydrogen production

Green hydrogen is a good option for replacing fossil fuels. Renewable energy is used for water electrolysis to boost the descarbonization. A system of solid oxide electrolysis electrolyzer driven by the solar field of heliostat and photovoltaic panels with a battery bank is techno-economically investigated in the northeast of Brazil condition. Model of the cell, design of solar field and PV-Battery system are carried out. The system composed of 60 modules produces 112.8 kg/h of green hydrogen. The cell operates at 950 °C with a current density of 2500 A/m² and reaches an efficiency of 95.33 %. The model has the highest relative error of 2.76 %. The Nernst voltage is the predominant voltage of cells, followed by the ohmic overpotential. The photovoltaic panels and battery have an average efficiency of 18.02 %. The solar field has an average efficiency is 34.6 %. The solar field and PV/battery bank account for 42.52 % and 39.65 % of global cost, respectively. The LCOH calculated is 9.43 US$/kg. Sensitivity analyses of the receiver and tower diameter and the lifespan battery on the LCOH are shown. Further researches are suggested.
