In today's world, life without electricity and energy sources is unimaginable for humans, while simultaneously, their use impacts the environment. Due to increased digitalization and the emergence of artificial intelligence usage, a rise in demand for electrical energy is to be expected. We are witnessing the shutdown of nuclear power plants, leaving room for the use of old technologies for electricity production, which contribute to environmental pollution, or the use of renewable energy sources. The global goal is certainly to turn to renewable energy sources, with a significant focus on solar energy given its availability and the simplicity of electricity production for every individual. The idea of this paper is the use of solar energy in a hybrid system that includes hydrogen and the analysis of the idea of using innovative technologies in power systems. Modelling a hybrid photovoltaic system involves the use of photovoltaic modules, batteries for short-term storage, and hydrogen for long-term storage. Considering the dangers of storing hydrogen in households (high flammability and explosiveness), the idea is directed towards using batteries in households, while excess electricity is handed over to a distributor who produces, stores, and uses the stored hydrogen to produce electricity when needed. Hydrogen is a "green" energy source, but it still shows some degree of unprofitability. In the future, the profitability of its use can be expected to increase with the reduction in system component costs and the introduction of fees for the production of harmful gases. Reducing energy losses and the overload of electricity distributors and using technologies that are tools in "green" management and "green" production, is one of the goals of this paper. To achieve all of the above, the use of blockchain technology in the energy sector was analyzed. A simulation of decentralized electricity exchange between individuals in the power system who use solar energy for production was carried out. The simulation was conducted in the sense of creating a web application that includes a smart contract and other necessary tools for the web application's operation. The functionality of the web application for decentralized electricity exchange was verified with all necessary explanations provided. At the end of the chapter, additional ideas on price regulation using Oracle and an analysis of blockchain technology usage in hybrid photovoltaic systems that use hydrogen were presented. Considering that all the mentioned technologies are very young, laws and regulations related to them were analyzed. It can be concluded that the technologies used in this paper are entirely friendly towards "green" global policy. The idea presented is creative and innovative, and it potentially could be one of the solutions for future global energy crises while simultaneously keeping pace with the trend of technological advancement and environmental protection
