Abstract

In facing major challenges of climate change, hydrogen is a clean-energy solution representing an important aspect of the transition to renewable energies. However, currently majority of hydrogen is produced from fossil fuels (‘brown hydrogen’), whereas green hydrogen is produced from renewable energy, so as the potential to provide clean energy. This article presents a design of solar green hydrogen production system and the simulation of its CPV (concentrated photovoltaic) output. To achieve cost-efficient green hydrogen production, we focus on improving efficiencies in two aspects, i.e., solar energy capture and electricity conversion. Firstly, to enhance the efficiency of focusing the sunlight, we use bi-axial concentrating solar optics combined with high-efficiency multijunction solar cells. Secondly, for the electricity conversion, use direct coupling between PEM (Polymer Electrolyser Membrane) electrolyser and PV system.

高性能绿色制氢系统

面对气候变化的重大挑战，氢是一种清洁能源解决方案，代表了向可再生能源过渡的一个重要方面。然而，目前大部分氢来自化石燃料(“棕色氢”)，而绿色氢来自可再生能源，因此具有提供清洁能源的潜力。本文设计了一种太阳能绿色制氢系统，并对其聚光光伏输出进行了仿真。为了实现具有成本效益的绿色制氢，我们重点提高两个方面的效率，即太阳能捕获和电力转换。首先，为了提高太阳光的聚焦效率，我们将双轴聚光太阳能光学器件与高效多结太阳能电池相结合。其次，在电能转换方面，采用PEM (Polymer Electrolyser Membrane)电解槽与光伏系统的直接耦合。
