“…Since the production of iron and steel is an energy intensive industry, the selection of the upgrading technique should be focused on the reduction of greenhouse gas emissions. A comparison of the environmental performance of the valorization routes of COG was performed by Zhang et al 183 The study evaluated the energy consumption and carbon dioxide emissions of the alternatives that have been discussed in previous sections (Table 6).…”

The recovery of energy and valuable compounds from exhaust gases in the iron and steel industry deserves special attention due to the large power consumption and CO 2 emissions of the sector. In this sense, the hydrogen content of coke oven gas (COG) has positioned it as a promising source toward a hydrogen-based economy which could lead to economic and environmental benefits in the iron and steel industry. COG is presently used for heating purposes in coke batteries or furnaces, while in high production rate periods, surplus COG is burnt in flares and discharged into the atmosphere. Thus, the recovery of the valuable compounds of surplus COG, with a special focus on hydrogen, will increase the efficiency in the iron and steel industry compared to the conventional thermal use of COG. Different routes have been explored for the recovery of hydrogen from COG so far: i) separation/purification processes with pressure swing adsorption or membrane technology, ii) conversion routes that provide additional hydrogen from the chemical transformation of the methane contained in COG, and iii) direct use of COG as fuel for internal combustion engines or gas turbines with the aim of power generation. In this study, the strengths and bottlenecks of the main hydrogen recovery routes from COG are reviewed and discussed.

“…Technological progress creates important breakthroughs for solving the contradictions between economic growth, environmental pollution, and energy consumption. [31][32][33][34] Previous studies on sustainable development models have basically focused on the macro and micro levels. At the macro level, most of the comprehensive analysis has been conducted through the construction of a rating index system, which has a certain integrity but fails to analyze the internal mechanism of the system in detail.…”

The economic development process is accompanied by energy consumption and environmental pollution, difficulties which must be overcome to realize sustainable development. A system dynamics model is constructed to simulate the pattern characteristics of an innovation-driven coupling system scenario for economic development, energy consumption and environmental pollution in the Yangtze River Economic Belt. Then, the impulse response relationship between technological progress and economic, energy and environmental system indexes is further explored by using a vector autoregression (VAR) model. The results show that (1) the model is suitable for predictive analysis. (2) Adjusting the model parameters shows that the innovation-driven development mode is the optimal sustainable development mode of the Yangtze River Economic Belt. (3) VAR model analysis shows that technological progress has a significant long-term positive impact on the economic development system index, and the growth of primary industry is the most significant. Technological progress has a significant long-term inhibition effect on energy consumption and environmental pollution system indicators, among which the inhibition effect on wastewater discharge and power consumption is the strongest. Finally, suggestions are proposed to increase investment in agricultural technology, smart countryside, and wastewater treatment.

“…More recently, Zhang et al. [ 20 ] proposed an LCA-based technology-environment-economy assessment framework to compare the competitiveness of six COG utilization routes. Their economic evaluation, however, solely relied on cost-benefit analysis and did not conduct an integrated evaluation of the environment and economy.…”
