“…For instance, Borba et al [2] estimated the potential for GHG emission reduction of industrial, transportation and petroleum sectors and associated abatment costs and evaluated energy policies to achieve climate change mitigation goals. Nogueira et al [29] evaluated the effects of different market-based mechanisms in the implementation of CCS (carbon capture and storage) technologies in thermal power plants in Brazil up to 2050. Recently, Lucena et al [23] compared different energy-economic assessment models to analyse the implications of carbon taxes and carbon abatment targets on the Brazilian energy system in terms of energy mix and GHG emissions.…”

“…Furthermore, this work assesses the impacts of enacting a tax on LCA-GHG emissions from the power sector as a market-based mechanism strategy to mitigate climate change. To this end, a robust model has been developed by integrating regional life cycle data of electricity generation systems in Brazil with optimised energy scenarios developed by using MESSAGE (Model for Energy Supply System Alternatives and their General Environmental Impact) tailored to a Brazilian context, the so called MESSAGEBrazil model [29]. The novelty of the paper is in the comparison of the effects of internalizing carbon costs on electricity production considering or not the life cycle emissions.…”

a b s t r a c tThis work evaluates implications of incorporating LCA-GHG (life cycle assessment of GHG emissions) into the optimisation of the power generation mix of Brazil through 2050, under baseline and low-carbon scenarios. Furthermore, this work assesses the impacts of enacting a tax on LCA-GHG emissions as a strategy to mitigate climate change. To this end, a model that integrates regional life cycle data with optimised energy scenarios was developed using the MESSAGE-Brazil integrated model. Following a baseline trend, the power sector in Brazil would increasingly rely on conventional coal technologies. GHG emissions from the power sector in 2050 are expected to increase 15-fold. When enacting a tax on directcarbon emissions, advanced coal and onshore wind technologies become competitive. GHG emissions peak at 2025 and decrease afterwards, reaching an emission level 40% lower in 2050 than that of 2010. However, if impacts were evaluated through the entire life cycle of power supply systems, LCA-GHG emissions would be 50% higher in 2050 than in 2010. This is due to loads associated with the construction of plant infrastructures and extraction and processing of fossil fuel resources. Thus, taxes might not be as effective in tackling GHG emissions as shown by past studies, if they are only applied to direct emissions.

“…The study finds, in this case, that all plants would be converted into electricity option at a carbon tax of US$ 150 tCO 2eq . Although coalfired power plants correspond to only 1.7% of the total installed capacity in Brazil [72], it is worth keeping in mind for the case of other countries.…”

Optimizing ethanol and bioelectricity production in sugarcane biorefineries in Brazil

et al. 2016

a b s t r a c tIn sugarcane biorefineries, the lignocellulosic portion of the sugarcane biomass (i.e. bagasse and cane trash) can be used as fuel for electricity production and/or feedstock for second generation (2G) ethanol. This study presents a techno-economic analysis of upgraded sugarcane biorefineries in Brazil, aiming at utilizing surplus bagasse and cane trash for electricity and/or ethanol production. The study investigates the trade-off on sugarcane biomass use for energy production: bioelectricity versus 2G ethanol production. The BeWhere mixed integer and spatially explicit model is used for evaluating the choice of technological options. Different scenarios are developed to find the optimal utilization of sugarcane biomass. The study finds that energy prices, type of electricity substituted, biofuel support and carbon tax, investment costs, and conversion efficiencies are the major factors influencing the technological choice. At the existing market and technological conditions applied in the upgraded biorefineries, 300 PJ y À1 2G ethanol could be optimally produced and exported to the EU, which corresponds to 2.5% of total transport fuel demand in the EU. This study provides a methodological framework on how to optimize the alternative use of agricultural residues and industrial co-products for energy production in agro-industries considering biomass supply chains, the pattern of domestic energy demand, and biofuel trade.

“…There is general agreement in academia that research has not concentrated on the impacts of water availability on energy and more specifically the electric power sector, which is noticed in a variety of work done for example on the role thermal power plants with CCS may play in Brazil's future electric power generation [11], the energy sector's vulnerability to climate change [13], the impact of climate change on electricity systems and markets [14] and on the vulnerability of hydropower generation to climate change in China [15], with investigation only recently starting to take place. Also, the Water-Energy Nexus (WEN) from an engineering systems perspective has received little attention [16] and as Leck et al [17] argue, the operationalisation of the WEN has to date been largely a paper exercise.…”

“…This has caused problems on many levels, as the decisions to build large power plants are made long before consulting locals, which indicates a lack of nexus thinking in the planning process and leave the power supply system highly susceptible to events like droughts, which is recognised in recent work done for Brazil by Nogueira et al [11] and Lucena et al [12]. As of 2013, thermal power generation in Brazil, mostly fueled by natural gas and sugarcane bagasse, acts as a complementary source to hydropower, in an attempt to optimize the system's operation [11], which causes further concerns.…”

This paper analyses the cross-sectoral integration of the water-energy nexus in Brazil. Recent droughts resulted in unprecedented water scarcity. This caused water shortages for population and agriculture, as well as for electricity production (hydropower being the main source of electricity production). As a result, the system became more vulnerable to blackouts. To alleviate the problem, fossil fuels were used as a back up. Droughts, floods and other water-related problems will not dissipate as time goes by in Brazil. The dependency on one single predominant source (hydropower) makes Brazil's electricity supply vulnerable. This study shows through data analysis, flow diagrams and metrics the interrelation between water and energy. Based on historical data, the analysis shows the importance of the water demand for hydropower, cooling for thermal plants, and the extraction and production of biofuels, as well as of the energy demand of water services (water supply, wastewater treatment).
