“…Ren et al [10] focused on research related to ultra-low carbon technology and committed to reducing CO 2 emissions. Wang et al [11] paid attention to the relationship between energy, water consumption and CO 2 in iron and steel enterprises, and evaluated the economic, energy-saving, water-saving and emission-reduction potential of 31 energy-saving technologies. Hasanbeigi et al [12,13] and He et al [14] summarized the latest progress of energy-saving technology in the ISPP, so readers could have a clear understanding of the energy use, the research and practice of energy-saving technology in the steel industry.…”

“…However, this does not mean that energy-saving technology has no energy-saving effect, so the calculation using Equations ( 12)-( 14) can better reflect the role of energy-saving technology in energy saving. This method also avoids searching for contribution values in the negative values calculated by Equations ( 10) and (11), which simplifies the calculation method but is more reasonable.…”

The effect of the traditional energy saving mode on process engineering is decreasing, so the idea of system energy saving is developing vigorously. This paper summarizes the existing studies on energy saving from three aspects—energy saving technology, energy management, comprehensive evaluation or analysis—and clearly finds that related studies on energy saving have been gradually promoted to promote the development of system energy saving in the whole process engineering process. Among them, the calculation of energy saving brought by energy saving technology is a difficult point in the research. This paper proposes a novel calculation method of energy saving by taking the iron and steel production process (ISPP) as an example. According to the actual data provided by a steel plant in China, the calculation method is validated effectively.

Summary We propose a new methodology to evaluate future electricity generation scenarios aiming to explore implications of different sets of power plants on the water‐energy nexus (W‐EN). We use two artificial neural networks: cascade forward back propagation and Kohonen neural networks (KNN). Initially, the future electricity production of the area under investigation is determined. Sequentially, water consumption is calculated for different combinations of plants. The scenarios with the lowest annual water consumption values are based only on wind and photovoltaic (PV) plants. Despite using only renewable energy, the inclusion of concentrating solar power in a future scenario brings a significant increase in water consumption, challenging the sustainability of this matrix. A conservative scenario (50% of electricity production by thermal power plants and 50% by renewable energy) shows the highest annual water consumption, also a barrier to sustainability.

“…Lee et al [15] focused on the energy-water-CO 2 nexus of the fossil-fuel-based power generation and mainly provided the policy implications on the optimization path of fossil fuel power structure adjustment. Wang et al [16] applied a plant-level nexus approach to assess the relationship between energy and water consumption, and CO 2 emission in a typical Chinese steel company. Damiana [17] presented a low-temperature waste-heat recovery in the European electric steelmaking industry and evaluated the impact of feasible interventions on primary energy and water consumption, as well as on CO 2 equivalent emissions.…”

Energy–Water–CO2 Synergetic Optimization Based on a Mixed-Integer Linear Resource Planning Model Concerning the Demand Side Management in Beijing’s Power Structure Transformation

et al. 2021

Studies on the energy–water–CO2 synergetic relationship is an effective way to help achieve the peak CO2 emission target and carbon neutral goal in global countries. One of the most valid way is to adjust through the electric power structure transformation. In this study, a mixed-integer linear resource planning model is proposed to investigate the energy–water–CO2 synergetic optimization relationship, concerning the uncertainties in the fuel price and power demand prediction process. Coupled with multiple CO2 emissions and water policy scenarios, Beijing, the capital city of China, is chosen as a case study. Results indicate that the demand-side management (DSM) level and the stricter environmental constraints can effectively push Beijing’s power supply system in a much cleaner direction. The energy–water–CO2 relationship will reach a better balance under stricter environmental constraints and higher DSM level. However, the achievement of the energy–water–CO2 synergetic optimization will be at an expense of high system cost. Decision makers should adjust their strategies flexibly based on the practical planning situations.
