Abstract

The research aims to calculate the cost of producing green hydrogen from the process of electrolysis of water using solar energy, and to evaluate the use of green hydrogen by mixing in different proportions with natural gas in existing power generation stations and to study the economic, technical and environmental returns, as the research methodology is based on a number of literature prepared in the same field of study and comparative research., and the experiences of some international companies (Siemens, Germany - GE, America - Mitsubishi, Japan) working in the same field, and visiting some power generation stations and obtaining data related to the research field and analyzing them in order to reach mathematical equations through which the cost of producing green hydrogen from the process of electrolysis of water using solar energy was calculated, as well as calculating the economic, technical and environmental returns of using hydrogen in power generation stations, as the research reached some results, the most important of which is that the added value of applying the technology in the research field is reducing harmful environmental emissions of carbon dioxide, as it decreases by only 10%. This percentage and its material return are small compared to the large financial cost that will be spent to modify the combustion systems in existing power plants, as well as the cost of producing hydrogen And its use in the combustion process, as well as the application of ignition technology using a mixture of hydrogen with natural gas on existing stations is expensive due to the high cost of hydrogen production taking into account the cost of OPEX & CAPEX in addition to the Initial Cost of the hydrogen production station, which represents 2.5 - 5 times the cost of natural gas production in addition to the necessary modifications to the ignition chambers and turbine stages, as the research concluded with several recommendations, the most important of which is expanding the establishment of new and renewable energy stations (solar-wind), producing hydrogen with clean energy free of carbon emissions affecting the environment has a social and economic return towards environmental sustainability, working to reduce the cost curve of hydrogen production and reaching competitiveness to reduce greenhouse gas emissions in the hydrogen production process, the Egyptian Electricity Holding Company expanding the establishment of seawater desalination stations and localizing seawater desalination technology using modern technologies that play an important role in reducing the cost of hydrogen production, the Egyptian Electricity Holding Company, when contracting for new electricity production stations, must include a system for using green hydrogen with natural gas in the combustion process.
