太阳能转化为氢能之探讨

Discussion about transformation of solar energy into hydrogen energy

介绍了新能源、太阳能、氢能,以及太阳能光热利用的低温、中温、高温利用。简述了几种常用的太阳能制氢工艺技术。详细阐述了Zn/ZnO氧化还原反应的太阳能光热化学循环制氢原理和两步法循环制氢的工艺流程。该技术为低成本高效率利用太阳能制氢的新途径,可供业内参考。

It introduced the new energy source, solar energy, hydrogen energy as well as the low-, medium-and high-temperature utilization of solar light and heat, stated several com- monly used hydrogen making techniques with solar energy. It stated in detail the principle of solar energy light-heat chemical circulation to produce hydrogen with Zn/ZnO oxidation-re- duction reaction and the process flow of two-steps circulating making hydrogen. This tech-nique is a new way with low cost and high efficiency to make hydrogen with solar energy, can be offered as a reference for others.
