Simulation of an 18 MW Alkaline Electrolysis Plant for Green Hydrogen Production in Abu Dhabi

Abstract

In the global effort to combat climate change and reduce greenhouse gas emissions, the creation of green hydrogen by water electrolysis powered by renewable energy sources, such as solar power, is becoming more important. In order to take advantage of the rich solar energy resources in the Al Dhafra region and offer sustainable electricity for the plant's hydrogen production operations, this research presents a simulation and analysis of an alkaline electrolysis plant located in Abu Dhabi. Based on basic chemical engineering design concepts, the research performs extensive calculations for the material and energy balances and estimates the capital costs of the process equipment. The findings show that the proposed alkaline electrolysis facility can produce hydrogen at a rate of 3753 kg/h and, as a beneficial byproduct, 28906 kg/h of oxygen. It is expected that an 18 MW alkaline electrolysis plant will require a total capital investment of about 100,000,000 USD, with an approximate yearly profit predicted of this process that reached of 50,000,000 USD. This analysis supports the region's sustainability goals and the global shift to a low-carbon future by highlighting the economic feasibility and environmental advantages of including the renewable energy-powered green hydrogen generation into Abu Dhabi's energy landscape.
