“…According to its power generation and related CO 2 emissions, the EF of the power plant was 1.11 t•CO 2 /MWh, which was higher than the carbon emission coefficient of the electric power supplied by coal-fired power plants in the thermal power industry to the regional power grid during the same period, resulting in the carbon EF of the electric power used in the target plant being higher than that of other enterprises using the regional power grid. Sakamoto also reported similar conclusions in the carbon emission accounting of different processes for iron and steel enterprises [48]. The establishment of a more precise measurement and monitoring system of carbon emission accounting at the enterprise level would help to accurately measure the power consumption coefficient and the dynamic change in the power consumption of the end-of-pipe technology in each department of the plant, which could increase the accuracy of the quantitative evaluation of the synergies.…”

Reducing industrial emissions has become increasingly important, given China’s ongoing industrialization. In this study, the reduction in CO2 emissions and air pollutants due to end-of-pipe treatment in a typical integrated steel plant in China was assessed. The emissions were subdivided into sector levels, including main production and auxiliary departments. The synergies of reducing air pollutants and CO2 emissions using end-of-pipe treatment technologies were quantified, including direct and indirect effects. The results show that (1) using the carbon balance method is more suitable for the greenhouse gas (GHG) emissions of the steel plants in China at the enterprise and sector levels. The carbon-related parameters adopted in the carbon balance method strongly impact the accuracy of the emission calculation. (2) Compared with the direct synergistic CO2 emissions caused by chemical reactions, the indirect emissions due to the power consumption of the end-of-pipe facilities is more significant. (3) To achieve the control of local air pollutants and CO2 emissions, the negative effects of CO2 emissions caused by the end-of-pipe treatment technologies should be considered.

“…An LCA of this local process is not described in the literature yet. The emission values based on the primary data used here are validated with the use of the literature data for different manufacturing processes of steel (Das & Kandpal, 1997; Hu et al., 2006; Renzulli et al., 2016; Sakamoto & Tonooka, 2000). The high amount of steel (62.58 kg per 1 kg of V 2 O 5 ) is related to the poor extraction rate of the magnetite.…”

In the course of the energy transition, storage technologies are required for the fluctuating and intermittently occurring electrical energy. The vanadium flow battery (VFB) is an especially promising electrochemical battery type for megawatt applications due to its unique characteristics. This work is intended as a benchmark for the evaluation of environmental impacts of a VFB, providing transparency and traceability. It considers the requirements for an industrial VFB from the technical and electrochemical point of view. The system design is based on a net capacity of 8 MWh and a net power of 1 MW. This ex ante study is a cradle‐to‐grave life cycle assessment (LCA) for a VFB to identify, analyze, and evaluate the environmental impacts for a lifetime of 20 years. Moreover, potential environmental impacts of several subsequent life cycles of the emission‐intensive and long‐lasting vanadium electrolyte are evaluated. With a focus on the electrolyte, the extraction process of vanadium pentoxide is studied in detail for the first time. Consequently, recommendations for the design of the life cycle of VFBs and for comparative LCAs with other energy storage technologies can be derived. Based on this work, more detailed work can follow, which helps to estimate the recycling potentials and emissions more precisely.
