Abstract
With the popularity of renewable energy, more and more countries and regions are utilizing renewable energy to produce hydrogen. However, renewable energy hydrogen production systems are often large in capacity and equipment, and require rational design as well as performance analysis of the system to satisfy the technicalities while ensuring the economics. In this paper, 12 different renewable energy systems for hydrogen production, including 6 grid-connected systems and 6 off-grid systems, are designed considering solar and wind energy as the main renewable energy sources in a place in China. Subsequently, simulations were carried out using HOMER software to compare and analyze the economic and technical performance of different schemes of renewable energy hydrogen production systems, and the best grid-connected and off-grid renewable energy hydrogen production system schemes were selected based on the comparison results.
