The mathematical tool aims to minimize the total expenses of capital and operational and guarantee the solidity of the services in the face of instability in the supply of renewable energy of the sun and wind
Hydrogen is the most abundant element of the universe and can be used as a clean fuel, emitting only water vapor when consumed in fuel cells or turbines. However, it is not in isolation in nature and it is necessary to extract it from compounds such as water (H2O) or natural gas (CH4).
The call “green hydrogen“It is produced through water electrolysis, a process that separates hydrogen from oxygen using electricity from renewable sources, such as solar OR wind. Therefore, the complete cycle, from production to use, the hydrogen does not generate carbon emissions, unlike “gray hydrogen” or “blue” derived from fossil sources.
For this reason, green hydrogen is seen as a key piece for the decarbonisation of industrial sectors that are difficult to electrify such as steel, heavy transport and production of fertilizers.
Another differential of the proposal is the unified treatment of multiple energy networks involved. The research has adopted integrated modeling of various systems, allowing to redistribute energy flows flexiblely according to the needs and opportunities of the economy.
Energy for isolated communities
As for the use of green hydrogen, as well as its use as a fuel for vehicles, in fuel cells or as a fuel for industrial use, on the turbines, Oroya underlines another possibility: source of electricity for isolated communities, such as those existing in various locations in the Amazon.
“Many of these communities, which do not have access to the electrical network, can benefit from their ability to archive large quantities of renewable energy for long periods, allowing the lighting and functioning of the equipment even in prolonged periods of low solar generation,” he says.
As for the possibility of immediately putting the Model X Dro model, the engineer gives an example: “We have at the University of State of Campinas an electropostat and an electrical bus in operation. In the near future, we can have a system for the production of integrated green hydrogen to a power station, enabling the operation of a bus in power in fuel power.
Oroya is currently a doctoral student at Feec. The study is part of his research project “Planning and functioning of green hydrogen production systems: a robust approach“, Supported by Fapesp.
“The development of the X Dro model represents an important methodological progress for energy planning under uncertainties, as it combines mathematical rigor with practical applicability in sustainable and complex systems, such as those of green hydrogen production”, says its doctoral consultant, Professor Marcos Julio Rider Flores.
