“…This approach is followed when assessing, for instance, the generation of marginal power. 2 [4,27]. Thus, while downstream processes of conventional thermal plants contribute to 87e96% of total environmental burdens, in the case of CCS thermal power plants downstream processes account for roughly 45% of total emissions, being the upstream processes more impactful.…”

“…Power supply portfolio scenarios for Brazil in a 2050 horizon have been developed in the Model for Energy Supply System Alternatives and their General Environmental Impact tailored to a Brazilian context (MESSAGE-Brazil), as described in Borba et al [2], Lucena et al [22], Malagueta et al [25], Nogueira et al [29] and Lima et al [21]. The MESSAGE-Brazil model is an integrated energy system model that estimates the least-cost expansion strategy for the Brazilian energy supply system to meet a certain exogenous demand, under specified constrains, namely energy resource availability, industrial installation capacity of each technology, investment costs, and political, social and environmental constraints.…”

“…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.…”

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.

A Comprehensive Study of Key Electric Vehicle (EV) Components, Technologies, Challenges, Impacts, and Future Direction of Development

Electric vehicles (EV), including Battery Electric Vehicle (BEV), Hybrid Electric Vehicle (HEV), Plug-in Hybrid ElectricVehicle (PHEV), Fuel Cell Electric Vehicle (FCEV), are becoming more commonplace in the transportation sector in recent times. As the present trend suggests, this mode of transport is likely to replace internal combustion engine (ICE) vehicles in the near future. Each of the main EV components has a number of technologies that are currently in use or can become prominent in the future. EVs can cause significant impacts on the environment, power system, and other related sectors. The present power system could face huge instabilities with enough EV penetration, but with proper management and coordination, EVs can be turned into a major contributor to the successful implementation of the smart grid concept. There are possibilities of immense environmental benefits as well, as the EVs can extensively reduce the greenhouse gas emissions produced by the transportation sector. However, there are some major obstacles for EVs to overcome before totally replacing ICE vehicles. This paper is focused on reviewing all the useful data available on EV configurations, battery energy sources, electrical machines, charging techniques, optimization techniques, impacts, trends, and possible directions of future developments. Its objective is to provide an overall picture of the current EV technology and ways of future development to assist in future researches in this sector.

Impacts of battery electric vehicles on renewable integration within the 2030 European power system

Summary The European Union supports the promotion of battery electric vehicles (BEVs) to decarbonize the transportation sector. This requires the intrinsic CO2 emissions of BEVs, defined as CO2 emissions from power plants producing the electricity to charge the BEVs, to be lower than the emissions of gasoline cars. To identify the individual power plants producing the electricity to charge the BEVs, a novel georeferenced optimal power flow simulation framework, which models power plants and transmission lines individually, is used in this work. The real central European power system is simulated at hourly resolution for the year 2030. A new model for BEVs, which considers the BEV owner's varying willingness to participate in the electricity market, is implemented into the framework. Simulation results show that there is limited potential for BEVs to reduce the curtailment of solar power (23% reduction of curtailment) and wind power (10% reduction). Instead of renewables, 65% of the electricity used to charge BEVs is produced by conventional power plants such as gas and coal power plants. Consequently, the intrinsic CO2 emissions of BEVs are found to be up to 25% higher than those of gasoline cars. An increase of CO2 prices to 100 €/tCO2 is found to be necessary for BEVs to have intrinsic CO2 emissions comparable to gasoline cars. These findings show that the decarbonization of personal transport requires more efforts that simply promote the sales of electric vehicles. Additional strategies such as increased CO2 prices, which transform the electricity sector from coal to gas and biomass, are required to enable an environmentally friendly implementation of BEVs.
