Estudo de parque eólico offshore para suprimento de uma usina de hidrogênio verde: análises técnica e econômica

Abstract

In view of the growing demand for energy in the coming years, mainly from polluting primary sources, an international agreement was signed in 2016 for 195 countries – the Paris Agreement – whose objective is reducing carbon emissions in the atmosphere from 2020. The main actions to achieve this goal are the promotion of alternative energy sources for the electricity sector and the energy use of hydrogen for applications aimed at industry and transport. Hydrogen production methods are diverse, but those that produce from renewable sources are the wanted in this transition due to zero emission of polluting gases, the so-called green hydrogen. In addition, electrolysis is highlighted because it requires water as a source for obtaining hydrogen through the electrolyser. In this sense, this work aims to evaluate, from a technical and economic point of view, the supply of electricity by offshore wind turbines to an electrolyser. For comparison purposes, some scenarios of possible systems with and without the electrolyser and connected or not to the grid were raised in a systems simulation software - HOMER. Some of the evaluation criteria are: the overlap of generation curves, the financial impacts of energy storage and the capacity factor compared to onshore wind. The results evidence a tendency of the systems for the resources connected to the grid, putting into question the certification definitions for obtaining green hydrogen
