本文从技术和经济潜力方面对太阳能热制氢的前景及其在未来氢供应中的可能作用进行了关键讨论。研究重点是太阳能驱动蒸汽甲烷重整、热化学循环、高温水电解和太阳能甲烷裂解。描述了正在进行的研究的过程和目标的发展现状和技术挑战。估计的氢气生产成本显示与其他选择的比较。对氢作为一种能源载体的当前讨论和今天的未来使用情况的总结，以及对最终用途技术发展状况的简要概述，说明了氢在2050年之前是否能成为重要的能源载体的不确定性。另一个重点是高太阳直接辐射地区的工业氢需求，这可能是未来几十年太阳能热制氢工艺进一步发展的主要驱动力。
This article provides a critical discussion of prospects of solar thermal hydrogen production in terms of technological and economic potentials and their possible role for a future hydrogen supply. The study focuses on solar driven steam methane reforming, thermochemical cycles, high temperature water electrolysis and solar methane cracking. Development status and technological challenges of the processes and objectives of ongoing research are described. Estimated hydrogen production costs are shown in comparison to other options. A summary of current discussions and today's scenarios of future use of hydrogen as an energy carrier and a brief overview on the development status of end-use technologies characterise uncertainties whether hydrogen could emerge as important energy carrier until 2050. Another focus is on industrial hydrogen demand in areas with high direct solar radiation which may be the main driver for the further development of solar thermal hydrogen production processes in the coming decades.
