Special Issue Information

Dear Colleagues,

The main focus of this Special Issue is the significant challenge that industrial and residential sectors face in fulfilling the future requirements of decarbonization. Depending on the amount of energy consumption or the quality of the required heat, electrification as decarbonization technology might not be economically feasible for specific applications. Furthermore, there are a number of processes with mineral sources of CO2 which cannot be removed through electrification and whose only alternative for decarbonization is carbon capture. This creates significant synergies between carbon capture and power to gas technologies as a potentially feasible way to decarbonized industrial and residential sectors in the mid-term.

Power to gas technology produces electrified fuels (hydrogen from water electrolysis) while fixing carbon (required in the methanation stage of hydrogen). This energy vector can be seen as a long-term renewable electricity storage system or an opportunity to reduce the carbon intensity of the gas network. Additionally, the use of direct air carbon capture as a carbon source can lead to the production of carbon-neutral electrified fuels.

Thus, technical, environmental, and economic assessment of systems which integrates carbon capture and power to gas technologies are key tools to boost alternative paths for the future decarbonization of energy systems. The scope of the Special Issue is wide and not limited to the topics mentioned above. Any research topic contributing to the development of decarbonization of the energy system through carbon capture and utilization by means of power to gas technologies will be considered.

The iron and steel industry is the largest energy-consuming sector in the world. It is responsible for emitting 4–5% of the total anthropogenic CO2. As an energy-intensive industry, it is essential that the iron and steel sector accomplishes important carbon emission reduction. Carbon capture is one of the most promising alternatives to achieve this aim. Moreover, if carbon utilization via power-to-gas is integrated with carbon capture, there could be a significant increase in the interest of this alternative in the iron and steel sector. This paper presents several simulations to integrate oxy-fuel processes and power-to-gas in a steel plant, and compares gas productions (coke oven gas, blast furnace gas, and blast oxygen furnace gas), energy requirements, and carbon reduction with a base case in order to obtain the technical feasibility of the proposals. Two different power-to-gas technology implementations were selected, together with the oxy blast furnace and the top gas recycling technologies. These integrations are based on three strategies: (i) converting the blast furnace (BF) process into an oxy-fuel process, (ii) recirculating blast furnace gas (BFG) back to the BF itself, and (iii) using a methanation process to generate CH4 and also introduce it to the BF. Applying these improvements to the steel industry, we achieved reductions in CO2 emissions of up to 8%, and reductions in coal fuel consumption of 12.8%. On the basis of the results, we are able to conclude that the energy required to achieve the above emission savings could be as low as 4.9 MJ/kg CO2 for the second implementation. These values highlight the importance of carrying out future research in the implementation of carbon capture and power-to-gas in the industrial sector. Full article
