Sistema de iluminação industrial off grid suprido por uma planta de geração de hidrogênio verde a partir de fonte solar: análise de viabilidade econômica

Abstract

The production of green hydrogen is taking increasingly space on the world stage, as it presents itself as a good substitute for fossil fuels. The inputs for the production of hydrogen in electrolysers are water and electricity, and the residues from the production of electricity in fuel cells are water and oxygen. The presente study aims to analyse the economic viability of a system for powering lights in an industrial warehouse located in Ceará based on hybrid solar photovoltaic generation with production and consumption of green hydrogen. The study measures the power of the lighting system and, based on this, it measures and defines criteria for the supply of light fixtures intermittently. Furthermore, the cost of the system components is surveyed, the forecast of TE and TUSD rates of the following years, the entry of cash flows, and then the simple payback indicators, IRR and LCOE, are defined. The results of the indicators were not economically favorable, but the dimensioning of the system indicates that the approached indicators enables improvement in future work proposing systems that may be viable when promoting changes in the current proposal, such as the insertion of the system connected to the grid or with the complement of another renewable source alongside solar.
