Under the "Dual-Carbon" targets, hydrogen production powered by renewable energy and hydrogen direct reduction offer approaches to integrating a high proportion of renewable energy and catalyzing the steel industry's transition towards a low-carbon footprint. The hydrogen-based steelmaking system (HBSS) presents a multi-energy interaction, encompassing processes from hydrogen production and ironmaking to the final steelmaking processes. Additionally, the high investment and operational expenses necessitate that decisionmakers prioritize enhancing the system's economic efficiency to ensure its long-term viability and effectiveness. In this study, we first introduced a multiperiod optimization model for HBSS, aiming to reduce the levelized cost of steel (LCOS) from both the investment and operational aspects. Then, the rollinghorizon approach has been used to overcome computational infeasibility for large mixed-integer linear programming problems by solving the problem periodically, including additional information from proximately following periods. We further compared it with the single-period and forward-looking approaches, indicating that the optimal result of LCOS varied from $406 to $520 for the different approaches. It proves that the rolling-horizon approach can lead to an economicsbetter solution than the single-period approach and is only a few percent away from the forward-looking approach.

Methane pyrolysis is one of the promising methods for producing low-carbon hydrogen, while one of the main problems of methane pyrolysis technology is soot clogging of the reactor space. In this work, soot deposits were studied during continuous methane pyrolysis in a corundum tube with an inner diameter of 50 mm. Experiments were carried out at temperatures of 1000 °C, 1050 °C, 1100 °C, 1200 °C and 1400 °C with methane flow rates of 1 L/min and 5 L/min. Each experiment lasted 1 h. The formed soot accumulated inside the reactor (corundum tube) and the connected filter, where the gaseous product of methane pyrolysis was separated from the soot. The gaseous product was studied by gas chromatography. The soot was studied by SEM, BET and ICP-MS. With an increase in the temperature of the pyrolysis process from 1000 to 1200 °C, the hydrogen yield increased from 28.64 to 92.74% and from 1.10% to 72.09% at a methane flow rate of 1 and 5 L/min, respectively. The yield of soot increased from 1.28 g at 1000 °C to 43.9 g at 1400 °C (at a methane flow rate of 1 L/min). With an increase in the flow rate of methane from 1 to 5 l/min, the yield of soot at 1200 °C increased by almost two times to 75.65 g. It was established that in the region of the reactor where maximum heating occurs, the accumulated soot sinters and forms dense growths. At 1050 °C, the particle size of soot varies from 155 to 650 nm, at 1200 °C—from 157 to 896 nm, and at 1400 °C—from 77 to 532 nm. The specific surface of soot was 3.5 m2/g at 1000 °C and 8.0 m2/g at 1400 °C. The purity of the produced carbon black was about 99.95%. This study is useful in the selection of materials and technical solutions for a pilot plant for methane pyrolysis.

“…The currently used hydrogen is produced almost entirely from fossil fuels, although hydrogen can also be manufactured from biomass, coal, or water. Natural gas or methane is particularly the main feedstock of hydrogen production, accounting for about 75% of the world's dedicated hydrogen production of about 75 million tons per year [12]. There are many ways to produce hydrogen, but not all of them are green and environmentally friendly.…”

The maritime industry is recognized as a major pollution source to the environment. The use of low- or zero-carbon marine alternative fuel is a promising measure to reduce emissions of greenhouse gases and toxic pollutants, leading to net-zero carbon emissions by 2050. Hydrogen (H2), fuel cells particularly proton exchange membrane fuel cell (PEMFC), and ammonia (NH3) are screened out to be the feasible marine gaseous alternative fuels. Green hydrogen can reduce the highest carbon emission, which might amount to 100% among those 5 types of hydrogen. The main hurdles to the development of H2 as a marine alternative fuel include its robust and energy-consuming cryogenic storage system, highly explosive characteristics, economic transportation issues, etc. It is anticipated that fossil fuel used for 35% of vehicles such as marine vessels, automobiles, or airplanes will be replaced with hydrogen fuel in Europe by 2040. Combustible NH3 can be either burned directly or blended with H2 or CH4 to form fuel mixtures. In addition, ammonia is an excellent H2 carrier to facilitate its production, storage, transportation, and usage. The replacement of promising alternative fuels can move the marine industry toward decarbonization emissions by 2050.
