Impact of hydrogen cells on economic efficiency and the environment according to renewable energy standards

Abstract

Purpose: The research goal of the work is to determine the levels of profitability of hydrogen cells and their impact on the environment. The authors of the article answer the question under what boundary conditions there is an economic justification for the use of hydrogen cells in various branches of the economy while respecting environmental regulations and standardizing energy production by the principles of a sustainable economy. Design/methodology/approach: The research was carried out using economic measurement model methods. These methods allowed the authors to calculate the market value of the investment with the assumed boundary criteria and to determine the economic effectiveness of the analyzed research problem. Additionally, the authors analyzed the problems of the widespread use of hydrogen in terms of its storage in technical, technological and economic terms. Findings: Research has shown that it is possible to obtain up to 7% by weight. hydrogen relative to the mass of the metal. Carbon nanofibers may become the material of the future for making hydrogen tanks. The use of fuel cells brings many benefits: simple structure and operation, neutral impact on the environment, and low noise level. Moreover, hydrogen fuel cell technology allows for efficient operation for a long time and the possibility of high momentary overloads, which allows for considerable scalability and wide application with economic justification. Practical implications: The presented models have shown that the project of their implementation is fully economically justified and will allow investors to make a rational investment decision. Originality/value: The original contribution of this work is the implication of the data on real research models. This data allowed the authors to make calculations and indicate directions of improvement for the construction of innovative hydrogen cell solutions as part of the standardization of regulations on renewable energy sources in various sectors of the economy. Keywords: Hydrogen, hydrogen storage, fuel cells. Category of the paper: Research paper.
