Abstract

In this model, we used a 50 WP photovoltaic panel to produce electrical energy. This electricity production was used directly and stored in a battery. In this design, we coupled batteries and hydrogen as a means of storing energy. In case of overcharging the battery, it will be attached with water electrolysis to convert the excess amount of chemical energy of the battery into hydrogen energy storage. Hydrogen will be stored as a compacted gas and in chemical storage. We used PEM (proton exchange membrane) electrolysis technologies to breakdown water molecules into hydrogen and oxygen, which were then stored in the designed tanks. Different supply voltages were used in our practical readings, with an average gaining of 22.8 mL/min on a voltage supply of 2. While using Ansys simulation software, we extrapolated hydrogen production until reaching 300 mL/min on 12 V of supply (which represents 220% higher production). By using the second phase of this model, hydrogen energy was converted back into electrical energy with the help of a PEM (proton exchange membrane) fuel cell when needed. This model explores the feasibility of energy storage in the form of hydrogen and chemical energy for off-grid communities and remote areas comprising batteries, water electrolysis, and fuel cells. The main purpose of hydrogen storage in this system is to store and handle the extra energy of system produced through PV panel and utilize it for any desired requirements.
在离网社区利用太阳能水电解以电池和制氢形式扩大能量储存的动态模型
在这个模型中,我们使用一个50 WP的光伏板来产生电能。产生的电能被直接使用并储存在电池中。在这个设计中,我们将电池和氢气结合起来作为储存能量的手段。在电池过充的情况下,它会附加水电解,将电池多余的化学能转化为氢储能。氢气将以压缩气体的形式储存在化学储存中。我们使用质子交换膜(PEM)电解技术将水分子分解成氢和氧,然后将其储存在设计的储罐中。在我们的实际读数中使用了不同的电源电压,在电压为2时,平均增益为22.8 mL/min。在使用Ansys仿真软件时,我们外推了氢气产量,直到在12 V的电源下达到300 mL/min(这代表产量提高了220%)。通过使用该模型的第二阶段,氢能在需要时在质子交换膜燃料电池的帮助下转换回电能。该模型探讨了在离网社区和偏远地区以氢和化学能形式储存能量的可行性,包括电池、水电解和燃料电池。本系统储氢的主要目的是存储和处理系统通过光伏板产生的额外能量,并将其用于任何所需的需求。
