提出了一种以超临界二氧化碳（CO2）为工质，利用太阳能为动力的热力循环制氢和热能联产的制氢方法。该系统由真空太阳能集热器、发电涡轮、水电解、热回收系统和给水泵组成。在本研究中，设计并制作了一个实验样机。在不同的天气条件下对循环的性能进行了实验测试。co2在集热器内高效转化为超临界状态，夏季co2温度可达190℃左右，冬季也可达80℃左右。这样的高温实现了电能和热能的联合生产。与现有的基于太阳能电池的电解水分解制氢需要使用能量要求高的太阳能电池不同，超临界循环中产生的电力可以直接用于从水中制取氢气。在夏季条件下，利用超临界循环产生的电能产生的氢气量约为1035 g /天，每个家庭使用100.0 m2的真空太阳能集热器，即使在冬季也约为568.0 g /天。此外，估计的热回收效率约为0.62。如此高的效率足以说明循环性能。
A hydrogen production method is proposed, which utilizes solar energy powered thermodynamic cycle using supercritical carbon dioxide (CO2) as working fluid for the combined production of hydrogen and thermal energy. The proposed system consists of evacuated solar collectors, power generating turbine, water electrolysis, heat recovery system, and feed pump. In the present study, an experimental prototype has been designed and constructed. The performance of the cycle is tested experimentally under different weather conditions. CO2is efficiently converted into supercritical state in the collector, the CO2temperature reaches about 190 °C in summer days, and even in winter days it can reach about 80 °C. Such a high-temperature realizes the combined production of electricity and thermal energy. Different from the electrochemical hydrogen production via solar battery-based water splitting on hand, which requires the use of solar batteries with high energy requirements, the generated electricity in the supercritical cycle can be directly used to produce hydrogen gas from water. The amount of hydrogen gas produced by using the electricity generated in the supercritical cycle is about 1035 g per day using an evacuated solar collector of 100.0 m2for per family house in summer conditions, and it is about 568.0 g even in winter days. Additionally, the estimated heat recovery efficiency is about 0.62. Such a high efficiency is sufficient to illustrate the cycle performance.
