“…Considering these essential characteristics of nGO and Global warming in recent years, arising partly from the spread of gases that intensify the greenhouse effect, causing global consequences, such as climate change, producing new ways to the energy source is a necessary search [18,19,20]. From this perspective, alternative, renewable and non-polluting energy sources have been developed, minimizing the environmental crisis, and helping to reduce gas emissions [21,22].…”

Nowadays, the search to develop sustainable materials using materials from renewable sources to multifunctional applications is a great challenge. In this context, the present research evaluated producing new carboxymethyl cellulose hydrogels with nano-graphene oxide incorporated into potential applications in biomedical and energy areas. Spectroscopies analysis (FTIR, Raman, UV Vis), X-ray diffraction, and morphological (SEM, TEM, BET) were used to characterize these hydrogels. In addition, quantum dots based on cobalt sulfide were made to evaluate the energy application. Moreover, biocompatibility was tested using an MTT assay. The results showed that the nGO changes the structure of hydrogels and their crystalline structure, mainly because of heat treatment and the donation of hydroxyl groups by CMC. In addition, the chemical groups of hydrogels suffer red and blue shifts by the nGO presence. Moreover, the nGO was homogeneously spread into the hydrogel matrix. Furthermore, the MTT assay was performed to analyze the cytotoxicity of hydrogels with nGO (over 90%). In addition, the cell solar production using hydrogels and cobalt quantum dots (size of 3 nm) provided a potential application of these materials to renewable energy sources.

“…Photovoltaic solar energy has the greatest capacity to generate low-cost electrical energy if compared to solar thermal, geothermal, wind and biomass energy (Hosseini and Wahid 2019;Laviola de Oliveira et al 2022), thus it is the object of study herein. According to the Ten-Year Energy Expansion Plan 2032 developed by Energy research company, regarding Centralized Energy Generation, photovoltaic solar technology remains the main source in this segment, as it accounts for about 97% of the overall expansion of distributed generation in Brazil (EPE-Brasil 2021;EPE & Brasil 2022).…”

Countries all over the world have been seeking ways and methods so that their electrical matrices can stand out using clean and renewable energy sources. In this context, this article presents a review with analysis of sector legislation on photovoltaic solar energy in Brazil. This study was grounded in four steps: (i) sample definition; (ii) theoretical basis; (iii) network analysis; and (iv) content analysis in two stages of research. Initially, a systematic literature review was carried out in order to map all the major and most cited works. The second stage consisted in reading and performing a critical analysis of government documents and reports from the energy sector in Brazil using a few bibliometric resources for such a purpose. Its results reveal that photovoltaic solar energy in Brazil has grown and expanded to different applications, since floating solar plants and subscription to solar energy are becoming increasingly attractive. Furthermore, a possible replacement of photovoltaic solar generation for thermoelectric plants has been investigated once there are a few positive aspects yet to be found thereof. As samples of the results obtained, we have that the replacement of works would allow the photovoltaic solar energy source to increase by 1% in the electrical matrix and would stop emitting 10,738,478 tons into the atmosphere, there would be a progressive decrease in the use of tariff flags (which affect directly to the final consumer) and a reduction in operating costs would also be achieved.

“…These technologies are continuously evolving and undergoing improvements to optimize the utilization of green hydrogen. While some technologies are already deployable, such as fuel cells in vehicles, buses and trains, and battery energy storage systems widely used across various applications [11][12][13][14][15][16], others are still in the developmental phase and require further investment and refinement before commercial viability. However, numerous countries worldwide are actively engaged in developing and testing these emerging technologies through pilot projects and practical experiments.…”

There is a growing interest in green hydrogen, with researchers, institutions, and countries focusing on its development, efficiency improvement, and cost reduction. This paper explores the concept of green hydrogen and its production process using renewable energy sources in several leading countries, including Australia, the European Union, India, Canada, China, Russia, the United States, South Korea, South Africa, Japan, and other nations in North Africa. These regions possess significant potential for “green” hydrogen production, supporting the transition from fossil fuels to clean energy and promoting environmental sustainability through the electrolysis process, a common method of production. The paper also examines the benefits of green hydrogen as a future alternative to fossil fuels, highlighting its superior environmental properties with zero net greenhouse gas emissions. Moreover, it explores the potential advantages of green hydrogen utilization across various industrial, commercial, and transportation sectors. The research suggests that green hydrogen can be the fuel of the future when applied correctly in suitable applications, with improvements in production and storage techniques, as well as enhanced efficiency across multiple domains. Optimization strategies can be employed to maximize efficiency, minimize costs, and reduce environmental impact in the design and operation of green hydrogen production systems. International cooperation and collaborative efforts are crucial for the development of this technology and the realization of its full benefits.
