Green Hydr.gen: Perspectives and Challenges in Using the Natural Gas Network in Ceará/Brazil

Journal of Geoscience and Environment Protection 2024年第3期12卷 70-94页

作者： Francisco Alfredo de Castro Mona Lisa Moura de Oliveira Lutero Carmo de Lima Daniel Silveira Serra Science and Technology Center State University of Ceará Ceará Brazil av. dr. silas munguba 1700 Fortaleza-Ceará Brazil

Climate change, mainly caused by the use of non-renewable fuels, has raised global concerns and led to the search for less polluting energy sources, making hydr.gen a promising energy alternative with the potential to contribute to changes in the energy mix of various countries through the use of technologies that enable its production and use with low or zero carbon emissions. In this context, Brazil has aroused great interest from other countries in exploring its renewable resources for the production of hydr.gen (green hydr.gen). In this sense, the use of natural gas pipelines and the use of hydr.gen in mixtures with natural gas hav. become the subject of studies due to their economically viable alternative for the immediate use of this energy vector. However, there are still technical and regulatory challenges regarding the integration of hydr.gen into the existing natural gas pipeline network. In this context, the present study aims to addr.ss the effects of hydr.gen interaction with the structure of natural gas pipeline steel and the regulatory barriers to the use of this network for the transportation of green hydr.gen, particularly in the state of Ceará/Brazil. After extensive analysis of literature and regulatory documents, it was concluded that: 1) Ceará/Brazil has strong potential to meet the demand for green hydr.gen through the use of solar and wind energy sources;2) there is feasibility for the adaptation or conversion of natural gas infrastructure for the transportation of green hydr.gen;3) discussions regarding the regulatory competence of green hydr.gen transportation and distribution through the natural gas network in Brazil are still incipient;4) the current regulation of the natural gas industry can serve as a subsidy for the regulation of green hydr.gen and natural gas transportation.

Chlamydoconidium-producing Trichophyton tonsurans: Atypical morphological features of strains causing tinea capitis in Ceará, Brazil

Objective: To report atypical morphological features of Trichophyton(T.) tonsurans strains associated with tinea capitis. Methods: Eighty-two T. tonsurans strains isolated in Ceará, Brazil, were analyzed regarding macro and micromorphological features and nutritional patterns. Results: Fifty-two samples presented abundant chlamydoconidia, which were produced in chains. Macroscopically, these strains developed small glabrous colonies that were firmly attached to the surface of the culture medium, with few or no aerial mycelia and intense rusty yellow pigmentation. Seven strains did not grow with stimulus from thiamine. Samples were heterogeneous regarding urease production and none presented in vitro hair perforation. Conclusions: The observation of T. tonsurans strains with distinct phenotypic features indicates the need to revise the taxonomic criteria for routine identification of this dermatophyte.
