Effect of TiS2 on Hydrogen Absorption and Desorption Performance of Mechanically Ball-Milled Mg95Ce5 Alloy

Symmetry, Journal Year: 2025, Volume and Issue: 17(1), P. 71 - 71

Published: Jan. 4, 2025

Magnesium-based materials have been considered to be potential hydrogen storage due their high capacity and abundance in natural resources. In order improve the performance of magnesium-based materials, a Mg95Ce5 alloy was prepared by using vacuum induction melting method. Moreover, TiS2 used as catalyst, series + x wt% (x = 0, 3, 5 10) composites with different contents were mechanical ball-milling The addition catalyst broke inherent symmetry at both atomic defect levels, potentially improving modifying diffusion pathways interaction sites. structural analysis results indicate that is composed Mg CeMg12 phases. After hydrogenation process, phases Mg95Ce5–TiS2 transformed into CeH2.73 MgH2. addition, CeS2 TiH1.5 could detected hydrogenated samples, indicating decomposed changed during reaction. Adding significantly absorption desorption kinetic properties, dehydrogenation peak temperature reduced from 389.5 °C 329.7 when content increased 0 10 wt%. However, inevitably reversable composites. thermodynamic measurement has almost no influence on enthalpy entropy changes process.

Network Evolutionary Game Analysis of Coal-to-Hydrogen CCUS Technology Dissemination in Carbon Trading Market

Sustainability, Journal Year: 2025, Volume and Issue: 17(2), P. 418 - 418

Published: Jan. 8, 2025

Integrating coal-to-hydrogen production with Carbon Capture, Utilization, and Storage (CCUS) is essential for reducing greenhouse gas emissions facilitating a shift towards more sustainable energy paradigm. This paper explores the diffusion of CCUS technology within sector against dynamic backdrop carbon trading market. An evolutionary game-theoretic approach utilized small-world network framework to analyze spread among enterprises. The simulation reveals that current market dynamics, along technological, market, policy-related uncertainties, do not robustly encourage adoption CCUS. As continues mature, prices become significant factor influencing in processes. Furthermore, investment costs, hydrogen prices, governmental policies are identified as pivotal elements propagation technology. study contributes valuable insights into development industry broader implications low-carbon transition strategies.

The deployment of large installed power capacities from intermittent renewable energy sources requires balancing to ensure the steady and safe operation electrical grid. New methods storage are essential store excess when is not needed later use it during high-demand periods, both in short long term. Power-to-Gas (P2G) an solution that uses electric produced renewables generate gas fuels, such as hydrogen, which can be stored for use. Hydrogen this manner utilized systems transportation fuel cars, trams, trains, or buses. Currently, most hydrogen fossil fuels. Solid-oxide electrolysis (SOE) offers a method produce clean without harmful emissions, being efficient all methods. objective work determine optimal operational parameters SOE system, lower heating value (LHV)-based efficiency total input power, based on calculations mathematical model. results provided three different operating temperature levels four steam utilization ratios. introductory chapter outlines motivation background work. second explains basics describes its types. third focuses solid-oxide electrolyzer systems. fourth details methodology, including formulations software used simulations. fifth presents with conclusions. final summarizes
