Abstract
The Intergovernmental Panel on Climate Change (IPCC) has pointed to the so-called “energy transition” from fossil fuels to renewable energy sources as the main path to lower emissions of greenhouse gases to attenuate atmospheric global warming and its impact on accelerating global climate change in reference to the pre-industrial era. That was called “decarbonization of the energy matrix”. In order to achieve that and deal with intermittency and spatial distribution of solar and eolic energy as well as biomass to produce electricity (power), IPCC and the International Energy Agency project that until 2050 hydrogen is the substance that will make viable to integrate, balance and storage all those forms of energy sources. Part of those three energy resources will be used to produce hydrogen instead of producing power directly. The theoretical (primary) and technical potential to produce hydrogen is therefore key to planning the energy transition the countries committed to. This work presents a methodology to assess the theoretical and technical production potential of renewable hydrogen from solar, wind, and biomass residues as well as the economic viability and the environmental assessment in the Brazilian context. Departing from the irradiance for solar, mean wind speed, and agricultural biomass residue generation and converting factors for the many known routes and technologies, the potentials are estimated. All data were collected from the literature and public records. The case study for the State of Paraná is presented since it offers the complexities of time-spatial variation of insolation, sustained wind, and agricultural production while it has a decentralized population and economy. Results showed that the state of Paraná could produce an average of 93.029 ton/km²/yr of hydrogen from solar photovoltaic projects, 4.670 ton/km²/yr from eolic plants, and 26.647 ton/km²/yr from biomass residues. The regions with the greatest potential are Pioneer North by solar, West Center by eolic, then East Center by from biomass residues by gaseification.
