标题： Impacts of photocatalytic hydrogen production on the European energy system

摘要： 特别是在太阳能辐射高的地区，光催化技术提供了一种有前景的低成本“绿色”氢气生产选项。 因此，本文使用一个开源能源系统优化模型，分析增加光催化技术比例对欧洲能源系统的影响，该模型涵盖了电力、工业和供热部门，并具有高空间和时间分辨率。 通过外生改变光催化成本，研究了在不同市场占比下光催化技术的部署情况。 结果表明，整合光催化技术需要系统性调整，因为它缺乏水电解的灵活负荷特性。 因此，在大规模采用光催化技术的情况下，预计氢气生产和需求将从西北欧向南欧发生显著的地理转移。 尽管存在这些挑战，安装的光催化技术成本仍处于光催化成本预测范围内。 因此，光催化技术可能有助于氢气生产的重大多样化，减轻其他可再生能源技术的材料需求。 然而，它需要战略性规划以避免锁定效应并最大化其潜力。 显示英文摘要

摘要： Especially in regions with high solar irradiation, photocatalysis presents a promising low-cost "green" hydrogen production option. Thus, this paper analyzes impacts of increasing photocatalysis shares on the European energy system using an open-source energy system optimization model covering the electricity, industry, and heating sectors with high spatial and temporal resolution. Photocatalysis deployment is investigated at various market shares by exogenously altering photocatalysis costs. The results show that integrating photocatalysis necessitates systematic adjustments since it lacks the flexible load attributes of water electrolysis. Therefore, a significant geographic shift in hydrogen production and demand from the Northwest to South Europe is expected in the case of large-scale photocatalysis adoption. Despite these challenges, installed photocatalysis shows costs within the photocatalysis cost projections. Thus, photocatalysis could contribute to a critical diversification of hydrogen production, easing material demands for other renewable technologies. Nevertheless, it requires strategic planning to avoid lock-ins and to maximize its potential.
