Um empreendimento deste porte, no setor energético, tende a gerar uma produção de conhecimento em diversas áreas impactadas por ele. Dessa forma, o objetivo deste artigo é analisar a produção científica relacionada ao GASBOL, avaliando o impacto deste gasoduto nas diversas áreas do conhecimento. Para tanto, foi realizada uma análise bibliométrica e qualitativa das publicações sobre o tema, entre 1999 e 2020. A análise bibliométrica demonstrou, dentre outros, a importância das conferências para a produção científica, a publicação da maioria dos artigos de periódicos em revistas bem avaliadas pela Capes e uma grande quantidade de autores filiados às empresas que administram o gasoduto. Na análise qualitativa, as publicações mais relevantes foram classificadas em cinco categorias, as quais foram descritas para a compreensão dos impactos do gasoduto e...

Após um primeiro leilão realizado em 2013, seguiuse um hiato de quatro anos sem novos leilões, que retornaram somente em 2017. Para além dos interesses comerciais no mercado energético brasileiro, os leilões do Pré-Sal representam um microcosmo das disputas geopolíticas entre diferentes atores internacionais pelo acesso ao petróleo, onde o Atlântico Sul torna-se uma região em disputa. Com isso, os leilões poderão ser estratégicos para os interesses brasileiros no setor energético.

Shale gas has the potential to reshape energy policy at national and international levels. Shale gas development can be an effective path to a low-carbon energy transition because natural gas, conventional or unconventional, has relatively lower emissions than other fossil fuels, as well as lower cost and abundant global reserves. This paper uses the SWOT analysis method to identify possibilities and challenges that shale gas development may face. To prepare the analysis, an advanced search was carried out on the Science Direct platform, investigating the strengths (S), weaknesses (W), opportunities (O), and threats (T) of the development of shale gas linked to the energy transition context. The most cited strength was abundant availability, followed by increased energy security. Regarding weaknesses, the most evident were environmental impacts and pollution...

Progressive exhaustion of non-renewable resources and growing demand raised debates regarding the development of public policies directed into promoting energy efficiency. It also raised concerns towards diversification of power sources in order to increase energy security of present and future consumers. Faced in this scenario, Brazilian natural gas industry has been highlighted in international geopolitical context due the important role of natural gas as an element of transition towards a greater presence of renewable sources (Santos et al. 2002). According to BP (2013), in 2012, natural gas presented an average share of 23.9% worldwide. This demonstrates a set of changes in consumption standards and a gradual displacement for oil byproducts. In the second half of the twentieth century, although Petrobras was established as the Brazilian's national company, the growth of natural gas industry was still left as a minor priority by energy planners. Since natural gas was considered a byproduct, it was employed as raw material for chemical, fertilizer industry and for productivity increase in oil exploration wells. The first natural gas discoveries in Brazil were associated with oil exploration and on shore production. Yet natural gas' share in Brazilian energy matrix was still a recent historical event and facing struggles to develop exclusive consumer markets. In the 1980s, natural gas production became more relevant because of discoveries in Campos Basin (Rio de Janeiro state), made possible due investments in deep-sea prospection and in the construction of gas pipelines. So, natural gas was able to

In the context, climate changes issues are clearly one of the big issues for our future. Thus, measures for mitigating its effects are treated, discussed, and analyzed to help us to reduce those problems. In this regards, Carbon Capture and Storage (CCS) technology may represent a strategic alternative for CO 2 abatement. Using bibliographic review methodology; including law analysis as well as the development of a logical explanation approach and deductive reasoning, in this paper, we analyzed the climate change mitigation strategy of CCS, and the perspectives of implementing this technology in Brazil, as well as we discussed the Civil Liability regarding CCS, focusing on the Brazilian environmental law. Our results show that the lack of a legal and regulatory framework of CCS activities represents the main barrier to its national development.

In this context, this work presents a 2G ethanol study as a mean to increase bioethanol production and availability. Currently, technologies use sugarcane bagasse for lignocellulosic ethanol production, which may unbalance the ethanol and sugar mill energy matrix, since bagasse and straw are the main fuel for power and steam generation. A possible solution is using biogas produced from vinasse biodigestion as a fuel instead of using biomass, enabling to shift a fraction of the sugarcane bagasse to 2G ethanol production and, at the same time, keeping power and steam production constant. This paper assesses that energy shift by analyzing ten different scenarios for power generation, comparing the amount of bagasse shifted, the increase in straw consumption, the increase in ethanol production and the reduction of environmental emissions in each scenario. The results show that, at least from the technical and environmental perspective, a combined cycle operating at a high pressure is the best alternative. It is possible to shift from 56.5% to 100% of the available bagasse using the combined cycle technology, which is also followed by an increase in straw consumption. In addition to that, the ethanol availability increase ranges from 28.5 to 50.4%. Moreover, the organic load disposal to the ground also decreases more than 90% compared to the conventional process due to the introduction of vinasse biodigestion.

This paper describes different strategies for using SNG as an effective substitute of NG in base-load, backup, and peak-shaving supply conditions to overcome NG supply interruptions from Local Distribution Companies (LDCs) for industrial consumers. The replacement of NG by SNG for industrial uses must deal with technical difficulties, which do not always allow both gases to be immediately exchangeable. The authors point out some of the difficulties involved in the process and propose ways to overcome them during a gas replacement process.

Located above the Paraná Sedimentary Basin, the region has great potential to produce shale gas and coalbed methane, situated in the Ponta Grossa and Rio Bonito Formation, respectively. In addition, the generation of biomethane from pig farming effluents in the state of Paraná has been gaining national prominence. In this sense, this work aimed to carry out a comparative SWOT analysis of three potential methane sources in the southern region of Brazil: (1) shale gas, (2) coalbed methane, and (3) biogas from swine effluents. This qualitative study debated each option regarding its regional impacts, developed gas distribution infrastructure, and investments in R&D for risk mitigation. A clearer consolidation of the federal government’s competence and states would bring more confidence and predictability to the market and promote better policy and legal secu...

The method used is discourse analysis. More specifically, we rely on Maarten Hajer’s concept of storylines, developed in his influential book The Politics of Environmental Discourse (1995). The purpose is to analyze how ruralist storylines, reshaped by the agribusiness lobby, has portrayed the Brazilian reality and how they were able to forge consensus about its controversial practices and questionable results. By uncovering how their discursive strategy was produced, we aim to verify which facts and arguments have selectively been exposed, and which ones have been excluded, or even shown in a distorted way. The main results show how these entrenched storylines have molded Brazil’s foreign policy.

Em termos de mercado, aumentar a oferta de gás natural pode ser essencial para reduzir a dependência do gás natural importado e pressionar os preços internamente e, assim, reduzir os custos em toda a cadeia. No entanto, a ausência de um ambiente regulatório com regulamentação específica para o gás não convencional traz insegurança jurídica no contexto de exploração de potenciais entrantes e empresas neste mercado. O crescimento da exploração exclusiva de gás nos Estados Unidos tem sido incentivado por um ambiente regulatório e econômico favorável, influenciado pelo uso de ferramentas regulatórias que tornaram o ambiente mais transparente. O objetivo geral deste artigo é analisar os riscos nas áreas jurídica, econômica e comercial que criaram obstáculos ao crescimento da atividade de exploração de gás não convencional no país, tendo como modelo comparativo o mercado dos Estados Unidos.

Several policies have been implemented to encourage less polluting technologies, among which is the Decarbonization Credit (CBio) in Brazil. This article discusses how the recent implementation of Decarbonization Credits (CBio) in Brazil can provide incentives for the development of BECCS. Through a literature review, this study selects the main points relevant to the promotion of BECCS, based on documents from supranational institutions, as well as on international experiences that have managed to promote this technology. From this, it was possible to list the most relevant aspects of government action to promote BECCS and relate them to the characteristics and obligations of CBio. The most relevant aspects of government action to promote BECCS are: compliance of BECCS with mitigation commitments; definition of policies explicitly focused on BECCS; develop...

Results.-On 16 patients, only 10 questionnaires were usable (questionnaires not filled, evaluation before, after not possible). At the end of 3 weeks, pain is very clearly improved with P 0.013, the score of kinesiophobia also (31.8 vs 41.2) with P in 0.009. The scores of acceptance are improved 27.44 against 21.88 at the exit but not significant with P in 0.14. The scores of change of behavior PSCOQ are all improved for all the patients for the hillside preservation (will to improve its strategies to face) P 0.0057 and no change for the intention. There was also a significant improvement of the anxiety (P in 0.03), not significant for the depression (P in 0.1). The physical parameters (schober, outstrip fingers ground, poplités angles, outstrip heel spank, shirado, sorensen) were improved. Conclusion.-For all the patients, is turned out an increase of the implication of the patient in its care, at the end of the program. It also seems that this type of program brings an improvement of the acceptance of the pain chronic without it is significant on our small population as well as of the capacity to manage better their disease. Studies on a bigger population and a remote follow-up would be desirable.

This study contributes the following observations: (1) The world energy intensity has decreased steadily, but the energy intensity of the Sao Paulo state has been volatile and has declined 2.3% since 1995. (2) In the period of study, declining energy intensity of the primary and tertiary sectors was observed. In contrast, the energy intensity of the secondary sector has been gradually increasing. (3) The energy efficiency effect was the primary driver of energy intensity change through 2007, and the economic activity effect subsequently had an increasingly more important role in the change. (4) The economic structure remained constant until 2004 when the services sector shift became more significant. It is hypothesized that the increasing energy intensity from 2005 to 2009 was caused by the growth of inefficient sugarcane bagasse consumption.

Due to the low permeability of these formations, the so-called unconventional reservoirs, only become viable if stimulated through horizontal drilling and hydraulic fracturing techniques. These techniques, like any other ones, have associated risks that should be very well managed and mitigated. This article aims to show that the benefits, in terms of fostering the local economy, job creation and energy security, outweigh the risks since they are known and well managed. In addition, suppliers present in country, able to provide these services properly, with numerous successful cases around the world, are identified in the article as well.

This study contributes the following observations: (1) The world energy intensity has decreased steadily, but the energy intensity of the Sao Paulo state has been volatile and has declined 2.3% since 1995. (2) In the period of study, declining energy intensity of the primary and tertiary sectors was observed. In contrast, the energy intensity of the secondary sector has been gradually increasing. (3) The energy efficiency effect was the primary driver of energy intensity change through 2007, and the economic activity effect subsequently had an increasingly more important role in the change. (4) The economic structure remained constant until 2004 when the services sector shift became more significant. It is hypothesized that the increasing energy intensity from 2005 to 2009 was caused by the growth of inefficient sugarcane bagasse consumption.

A devout Muslim would suggest that this is rather in the hands of God than of professors. The most sophisticated computer programmes have not been able to predict the developments of the stock markets or the oil price of ...

Due to the low permeability of these formations, the so-called unconventional reservoirs, only become viable if stimulated through horizontal drilling and hydraulic fracturing techniques. These techniques, like any other ones, have associated risks that should be very well managed and mitigated. This article aims to show that the benefits, in terms of fostering the local economy, job creation and energy security, outweigh the risks since they are known and well managed. In addition, suppliers present in country, able to provide these services properly, with numerous successful cases around the world, are identified in the article as well.
