“…However, it would allow to reach a fully decarbonized electricity system. The current Brazil's electricity grid emission factor is slightly higher than 0.135 tCO2/MWh [43]. According to the results presented in Table 4, the estimated emission factor for COPPE (0.082 tCO2/MWh) and Greenpeace (0.066 tCO2/MWh) are very similar and decrease 39.4% and 50.8% comparatively to the current emissions factor value.…”

“…The indirect emissions are related, for example, to the manufacturing, construction and transport processes associated with the entire energy system. Therefore, we highlight the need to further assess the indirect CO2 emissions costs in a fully energy system as discussed for example by [41][42][43]. The fully renewable power supply system scenario presented in this paper is based on a set of assumptions [10,20,30,36,37].…”

The Brazilian electricity system is an important example of a large country relying on a high renewable energy matrix with a major focus on hydropower, which has historically allowed for low carbon electricity production.However, the increase in the demand and climate change impacts on the availability of these renewable resources represent important challenges for long-term power planning. The contribution of this paper is twofold: Firstly, a first attempt to use the EnergyPLAN model for the analysis of the Brazilian electricity sector and in particular to study future scenarios is presented. Secondly, the possibility of achieving a 100% RES system is also addressed. The 100% RES scenario is found to be theoretically possible but a substantial increase in the overall installed capacity would be required, to support the grid mainly during the spring and summer season. The results underline the importance of seasonal complementarity of hydro and wind power and reveal how an increase in RES would add exportation potential, reducing also the Brazilian external energy dependency. The study identifies risk factors for these high RES scenarios and outlines several avenues for future research to address cost, environmental and technical uncertainties of the system.

Biomass is responsible for 25% of the primary energy supply in Brazil. However, future biomass demand will be influenced by many factors. This study evaluates potential pathways for the utilization of biomass in Brazil until 2050, while considering novel biobased sectors (renewable jet fuel and biochemicals), resource competition, and greenhouse gas (GHG) emissions. Whereas other least‐cost optimization models assess biobased options to meet energy and chemicals demand in Brazil to a limited extent, this study provides a detailed breakdown of biomass feedstock, including an extensive portfolio of biomass conversion technologies. A least‐cost optimization model is used to assess the demand for energy and chemicals, and the competition between biomass and other climate‐mitigation measures such as renewable power generation technologies, carbon capture and storage (CCS), and energy efficiency. Varied over the three scenarios, 86–96% of the sustainable biomass supply potential is used. Under more stringent mitigation targets, novel biomass conversion technologies start to play an important role: Biobased electricity production with CCS, jet fuel production from lignocellulosic biomass, and chemicals are partly produced from ethanol and bio‐naphtha. The modeling framework provides a transparent view of which type of biomass can be used for which specific purpose. It is therefore an interesting tool for future research, for example to examine the dynamic interaction with demand for land. © 2019 The Authors.

“…The potentially significant contribution of BECCS for national greenhouse gas reduction is similar to a country like Brazil, for which it has been concluded that carbon capture from biogenic sources in ethanol production could play an important role for carbon mitigation provided sufficiently strong climate policy are put in place (Rochedo et al, 2016). However, an important difference between the Swedish biogenic emission sources investigated in this work and the Brazilian cases is that the Swedish emission sources are in the form of pulp and paper plants, which are much larger than the ethanol plants in Rochedo et al (2016). This, together with their coastal location, makes transport (by ship) much less costly than the costs of the large (inland) pipeline network required to be established for ethanol plant capture in Brazil.…”

Marginal Abatement Cost Curve of Industrial CO2 Capture and Storage – A Swedish Case Study

2020

Carbon capture and storage (CCS) is expected to play a key role to achieve deep emission cuts in the energy intensive industry sector. The implementation of carbon capture comes with a considerable investment cost and a significant effect on the plants operating cost, which both depend on site conditions, mainly due to differences in flue gas flow and composition and depending on the availability of excess heat that can be utilized to power the capture unit. In this study we map the costs required to install and operate amine-based post-combustion CO 2 capture at all manufacturing plants in Sweden with annual emissions of 500 kt CO 2 or more, of both fossil and of biogenic origin, of which there are 28 plants (including a petrochemical site, refineries, iron and steel plants, cement plants and pulp and paper mills). The work considers differences in the investment required as well as differences in potential for using excess heat to cover the steam demand of the capture process. We present the resulting total CO 2 capture costs in the form of a marginal abatement cost curve (MACC) for the emission sources investigated. Cost estimations for a transport and storage system are also indicated. The MACC shows that CO 2 capture applied to 28 industrial units capture CO 2 emissions corresponding to more than 50% of Swedish total CO 2 emissions (from all sectors) at a cost ranging from around 40 €/t CO 2 to 110 €/t CO 2 , depending on emission source. Partial capture from the most suited sites may reduce capture cost and, thus, may serve as a low-cost option for introducing CCS. The cost for transport and storage will add some 25 to 40 €/t CO 2 , depending on location and type of transportation infrastructure.
