Typical shutdown water content states were defined, and cold start experiments were performed to analyze the variations in cumulative water production and initial 1 kHz impedance under different conditions. Additionally, 85 freeze-thaw (F-T) cycles were carried out to quantify the effects of various shutdown water content on fuel cell lifetime through polarization resistance growth.

The Co₃O₄ catalyst must undergo a surface reduction induction period to trigger its high catalytic activity, yet its bulk phase maintains its original crystalline structure. The results demonstrate that the Co₃O₄ catalyst calcined at 800 °C exhibits the highest hydrogen production rate of up to 4145.8 mL min⁻¹·g⁻¹, which is much higher than that of the CoO catalyst. This can be ascribed to its optimized crystallinity, mixed valence of Co²⁺/Co³⁺, and more oxygen vacancies. Meanwhile, the catalyst calcined at 800 °C also displays excellent cycling stability. The study further investigated the effects of NaBH₄ and NaOH concentrations on catalytic activity, revealing that the NaOH concentration can significantly affect the reaction rate. Kinetic analysis indicated that the hydrolysis of NaBH₄ over the Co₃O₄ catalyst follows a zero- order reaction with an activation energy of 37.9 kJ mol⁻¹.

Using panel regression techniques with fixed effects, System GMM, and instrumental variable approaches, we address potential endogeneity concerns while accounting for regional heterogeneity across China's provinces. Our results yield four principal findings. First, green bonds demonstrate a significant positive relationship with renewable energy investments, with coefficients ranging from 7.148 to 9.124 across model specifications. Second, contrary to theoretical expectations, geopolitical risks show positive associations with renewable energy investments, suggesting that energy security considerations may accelerate rather than impede renewable transitions. Third, oil price volatility positively influences renewable energy investments, indicating possible risk-hedging motivations.

Catalysts based on noble metals (Pt, Pd for HER and Ir, Ru for OER) are efficient and benchmark towards water electrolysis, but high cost, scarcity, and lower stability prevent their applicability for industrial application. Up to now, rare earth/transition metal catalysts are still not more efficient and durable for water electrolysis. Herein, we report a Nd₂Se₃–Mn₂O₃ heterojunction assembled on stainless steel (SS) using a hydrothermal method to ameliorate the properties of electrocatalysts via interface engineering for HER, OER, and overall water splitting. Under comparison with two pure electrocatalysts (Nd₂Se₃ and Mn₂O₃), the full water splitting performance is checked in 3 and 2-electrolysis systems using the alkaline medium. Here, different physical characterization like XRD and TEM/EDX showed that the strong combination of two materials (Nd₂Se₃ and Mn₂O₃) leads to the structural reconstruction of precursor and spherical formation with an increasing number of disordered pores and active sites. Besides, XPS confirmed the strong electronic coupling, which enhances the adsorption of hydrogen atoms on the catalyst surface compared to pure ones. At 10 mA cm⁻², Nd₂Se₃–Mn₂O₃ delivers the smallest overpotential of 260 and 121 mV for OER and HER, indicating that coupling effects of Nd₂Se₃ and Mn₂O₃ are responsible for boosting the catalytic performances. The effect of small charge transfer resistance and large surface area for HER-OER about bifunctional electrocatalysts is confirmed using EIS and C_dl. Furthermore, an assembled Nd₂Se₃–Mn₂O₃//Nd₂Se₃–Mn₂O₃ device in a 2-electrode electrolyzer exhibited a cell voltage of 1.47 V along with excellent stability of 96 h at 10 mA cm⁻² for overall water splitting.

This study aims to investigate by using CFD modelling a hydrogen fuelled marine dual-fuel engine to identify operating settings ranges for different hydrogen energy fractions (HEF), as well as parametrically optimise the diesel fuel injection timing and temperature at inlet valve closing (IVC). A large marine four-stroke engine with nominal power of 10.5 MW at 500 rev/m is considered, assuming operation at 90 % load and hydrogen injection in the cylinders intake ports. CFD models are developed for several operating scenarios in both diesel and dual-fuel modes. The models are validated against measured data for the engine diesel mode and literature data for a hydrogen-fuelled light-duty engine. A convergence study is conducted to select the grid compromising between computational effort and accuracy. Parametric runs for 20 %, 40 % and 60 % HEF with different IVC temperature and diesel start of injection are modelled to quantify the engine performance, emissions, and combustion characteristics. A single parameter optimisation is conducted to determine the most effective pilot diesel injection timings. The results reveal the IVC temperature range for stable hydrogen combustion to avoid incomplete combustion at low IVC temperature and knocking above 360 K. The proposed settings lead to higher peak heat release rate and in-cylinder pressure compared to the diesel mode without exceeding the permissible in-cylinder pressure rise limits for 60 % HEF. However, NOx emissions increase to 12.9 g/kWh in the dual-fuel mode. The optimal start of injection (SOI) for the diesel fuel, in the case of 60 % HEF, is found 8 °CA BTDC resulting in an indicated thermal efficiency of 43.2 % and stable combustion. Advancing SOI beyond the optimal value results in incomplete combustion.
