“…Figure 15 provides a comprehensive overview of the CO2 to ethylene conversion process. The initial step involved the capture of CO2 from a high partial-pressure stream, such as biogas or industrial flue gas [143][144][145][146][147]. From the information provided by some companies, such as Carbon Clean, the costs of CO2 capture from industrial flue gas through membrane, pressure swing adsorption, and scrubbers were comparable for large-scale processes, ranging between USD 30-$0/ton CO2 [146,148].…”

Electrocatalytic CO2 reduction to valued products is a promising way to mitigate the greenhouse effect, as this reaction makes use of the excess CO2 in the atmosphere and at the same time forms valued fuels to partially fulfill the energy demand for human beings. Among these valued products, methane is considered a high-value product with a high energy density. This review systematically summarizes the recently studied reaction mechanisms for CO2 electroreduction to CH4. It guides us in designing effective electrocatalysts with an improved electrocatalytic performance. In addition, we briefly summarize the recent progress on CO2 electroreduction into CH4 from the instructive catalyst design, including catalyst structure engineering and catalyst component engineering, and then briefly discuss the electrolyte effect. Furthermore, we also provide a simplified techno-economic analysis of this technology. These summaries are helpful for beginners to rapidly master the contents related to the electroreduction of carbon dioxide to methane and also help to promote the further development of this field.

“…Consequently, the concept of decarbonization, i.e., the sustainable reduction of carbon emissions in the atmosphere, has been considered a potential innovation in the steel industry [11,12]. Recent highlights in the literature describe the use of green hydrogen to reduce CO2 emissions in steel industries [1,3,12]. According to Souza Filho et al (2022), green hydrogen produced through renewable energy will remain a significant bottleneck in the coming decades.…”

“…These emissions result from the steel production process, involving high temperatures in coke-fueled furnaces, leading to intensive energy consumption and gas release into the atmosphere. In this context, the need for significant changes has become increasingly evident over the years [1,2]. Mallet et al (2023) describe the decarbonization of the iron ore production industry as a daunting yet essential task.…”

Sustainable Development has been the target of continuous global efforts, aiming to reduce dependence on natural resources, increase waste reuse, promote social well-being, and preserve the environment. This article addresses the discussion of implementing ESG principles in the steel industry. Concepts and technologies such as "Green Steel," circular economy, recycling technologies, carbon capture and storage, and the use of renewable energies are explored. These approaches represent significant advancements towards a more sustainable steel sector, with meaningful socio-economic and environmental benefits.

“…As for the future cost of green hydrogen, there are several factors that could impact it, such as advancements in technology, economies of scale, and government policies and incentives. It is predicted that the cost of green hydrogen could decline significantly in the coming years, making it more competitive with traditional fossil fuels [ 2 ]. A report published by the International Renewable Energy Agency (IRENA) suggests that the cost of green hydrogen could fall by 50% or more by 2030, driven by declining costs for renewables and electrolyzers, as well as improvements in efficiency and economies of scale [ 3 ].…”
