“…The calculated results showed that as the connected molecules were CO 3 2– and O 2 , the system energy was 53.98 and 54.47 eV, respectively. As the increase of system energy indicated the decrease of system stability; , hence, the dominant transformation process was that Fe 2+ in the layer was oxidized to Fe 3+ in aerobic, which caused the layers of Mg 1– X Fe X (OH) 2 became positively charged and then CO 3 2– entered into the interlayers and resulted in the formation of MgFe–CO 3 2– -LDHs due to the electrostatic attraction. , …”

Ferroan brucite, Mg 1−X Fe X (OH) 2 (0.05 < x < 0.35) was a common mineral product preserved in serpentinized peridotites. Studying the evolution of Mg 1−X Fe X (OH) 2 with different doping amounts of Fe 2+ was beneficial to reveal the role of Fe 2+ in forming different kinds of evolution products and the reasonable utilization of Mg 1−X Fe X (OH) 2 resources. In this study, Mg 1−X Fe X (OH) 2 with x being 0.05, 0.1 0.15, 0.2, and 0.3 were successfully prepared, characterized, and structurally refined in detail. The evolution products of Mg 1−X Fe X (OH) 2 in the presence of H 2 O, CO 2 , and O 2 were clearly investigated to assess the evolution process and the role of Fe 2+ . The evolution products were mainly CO 3 2− intercalated MgFe-layered double hydroxides (MgFe−CO 3 2− -LDHs) and MgCO 3 •3H 2 O. The content of MgFe− CO 3 2−-LDHs in the evolution products increased with the Fe 2+ doping content increased. While the content of MgCO 3 •3H 2 O changed in the opposite direction and completely disappeared as the doping content of Fe 2+ was 20%. Accordingly, the evolution mechanism of Mg 1−X Fe X (OH) 2 was afforded based on various characterization and calculation on the deformation and system energy of the products by molecular simulation. In the evolution process, the oxidization of Fe 2+ to Fe 3+ in Mg 1−X Fe X (OH) 2 by O 2 forced the entrance of CO 3 2− into the interlayers. Meanwhile, high content of doping Fe 2+ in Mg 1−X Fe X (OH) 2 resulted in the easy formation of MgFe−CO 3 2− -LDHs. Correspondingly, the change of surface charge, magnetic property, and adsorption ability toward Congo red was tested after evolution.

“…This research offers valuable insights into the design and control of pure GDGHSs. Ref [82] highlights the reliability of windbased pure GDGHS faces technical challenges due to the variability of wind energy and the resulting low total inertia of such systems. To enhance the stability of these systems and the overall power grid, the paper suggests synthetic inertia to wind power plants.…”

In recent years, the development of hydrogen energy has been widely discussed, particularly in combination with renewable energy sources, enabling the production of “green” hydrogen. With the significant increase in wind power generation, a promising solution for obtaining green hydrogen is the development of wind-to-hydrogen (W2H) systems. However, the high proportion of wind power and electrolyzers in a large-scale W2H system will bring about the problem of renewable energy consumption and frequency stability reduction. This paper analyzes the operational characteristics and economic feasibility of mainstream electrolyzers, leading to the proposal of a coordinated hydrogen production scheme involving both a proton exchange membrane (PEM) electrolyzer and an alkaline (ALK) electrolyzer. Subsequently, a coordinated control based on Model Predictive Control (MPC) is proposed for system frequency regulation in a large-scale W2H islanded microgrid. Finally, simulation results demonstrate that the system under PEM/ALK electrolyzers coordinated control not only flexibly accommodates fluctuating wind power but also maintains frequency stability in the face of large disturbances. Compared with the traditional system with all ALK electrolyzers, the frequency deviation of this system is reduced by 25%, the regulation time is shortened by 80%, and the demand for an energy storage system (ESS) is reduced. The result validates the effectiveness of MPC and the benefits of the PEM/ALK electrolyzers coordinated hydrogen production scheme.
