In line with the Nationally-Determined Contribution (NDC), the Indonesian steel industry must move to a less energy and carbon-intensive production where the hydrogen-based Direct Reduction Iron Electric Arc Furnace (H2-DRI-EAF) pathway comes as a prominent alternative. However, due to the complexity of the transition it is important to understand the key uncertainties in the adoption of H2-DRI-EAF production pathway in the steel industry, particularly since it must also address the availability of hydrogen domestically. We developed a system dynamics model, conducted a sensitivity to investigate the uncertainties, and to evaluate their effect on the observed indicators. Our results conclude that GDP growth, hydrogen maximum injection rate, and renewables development rate as the key uncertainties to the adoption of hydrogen in the steel industry, and ultimately to the effort in decarbonizing the sector. Furthermore, we found that domestic hydrogen production can fulfil between 20% and 77% of the demand in the Indonesian steel industry. In Indonesia's case, our results show that the share of H₂-DRI-EAF could be between 29 and 38% and the share of hydrogen in the fuel mix could vary widely from 1.91% to 18.9%. The findings in this study could potentially be useful for the steel industry and policy makers alike to design a comprehensive decarbonization strategies.

根据国家自主贡献（NDC），印尼钢铁行业必须转向低能源和低碳生产，其中氢基直接还原铁电弧炉（H2-DRI-EAF）途径是一个突出的替代方案。然而，由于转型的复杂性，重要的是要了解在钢铁行业采用H2-DRI-EAF生产途径的关键不确定性，特别是因为它还必须解决国内氢气的可用性。我们建立了一个系统动力学模型，对不确定性进行了敏感性研究，并评估了它们对观测指标的影响。我们的研究结果表明，GDP增长、氢气最大注入率和可再生能源发展速度是钢铁行业采用氢气的关键不确定因素，并最终影响该行业的脱碳努力。此外，我们发现国内氢气生产可以满足印尼钢铁行业20%至77%的需求。在印度尼西亚的情况下，我们的结果表明，H2-DRI-EAF的份额可能在29和38%之间，氢在燃料结构中的份额可能在1.91%到18.9%之间变化很大。这项研究的发现可能对钢铁行业和政策制定者设计全面的脱碳战略有用。

The design of cost-effective oxygen reduction reaction (ORR) catalysts in microbial fuel cells (MFCs) remains a challenge. Herein, a mesoporous silica (mSiO₂) assisted protection strategy is developed to synthesize highly dispersed CuCo nanoalloys embedded in nitrogen doped carbon Cu/Co-NC@mS catalyst using zeolitic imidazolate framework (ZIF) as carbon and nitrogen sources. The results revealed that the mSiO₂ protection holds the potential to inhabit CuCo nanoalloys from aggregation and thus promotes the formation of highly dispersed small CuCo nanoparticles. The obtained catalyst with pyrolysis temperature (T) of 800 °C (Cu/Co-NC@mS-800) achieves the best ORR performance among Cu/Co-NC@mS-T catalysts, yielding a maximum power density of 1000 mW m⁻² when employed as air cathode MFCs. The significantly enhanced ORR performance of Cu/Co-NC@mS-800 could be attributed to following aspects: a) highly dispersed small CuCo nanoalloy particles, improved mesoporous surface area and volume owing to mSiO₂ protection; (b) the formation of concave regular dodecahedron mesoporous structure with thin graphtic carbon layer as support; (c) the synergetic effect between CuCo nanoalloys. This work provides a facile strategy for the preparation of highly dispersed bimetal nanoalloys with enhanced electrocatalytic performance for energy-related applications.

在微生物燃料电池（MFCs）中设计高性价比的氧还原反应（ORR）催化剂仍然是一个挑战。本文采用介孔二氧化硅（mSiO2）辅助保护策略，以沸石咪唑酸骨架（ZIF）为碳氮源，在氮掺杂碳Cu/Co-NC@mS催化剂中包埋高分散CuCo纳米合金。结果表明，二氧化硅保护层有可能抑制CuCo纳米合金的聚集，从而促进CuCo纳米颗粒的形成。所得催化剂热解温度(T)为800℃（Cu/Co-NC@mS-800），在Cu/Co-NC@mS-T催化剂中ORR性能最好，用作空气阴极mfc时功率密度最大可达1000 mW m−2。Cu/Co-NC@mS-800的ORR性能显著提高主要得益于以下几个方面：1)CuCo纳米合金颗粒高度分散，mSiO2的保护提高了介孔表面积和体积；(b)形成以薄石墨碳层为支撑的凹形规则十二面体介孔结构；(c) CuCo纳米合金间的协同效应。这项工作为制备具有增强电催化性能的高分散双金属纳米合金提供了一种简便的策略，用于能源相关应用。

Submerged dc plasma generated by nanosecond pulses in ethanol and methanol mixtures with water confirmed efficient production of the hydrogen synthesis gas H₂ + CO. The comparison of ethanol and methanol was made for their 35% contents in water. The methanol electrolyte exhibited about 25% more efficient production of synthesis gas compared with ethanol. Tests with 9 ns 9 kV negative dc pulses at the average power of 10 W confirmed production of up to 0.5 l/min of the synthesis gas with over 65% content of H₂. In both electrolytes the experiments indicated important role of small gas bubbles in the process. The bubbles were evidently generated by very short streamers formed during the dc pulses. The extraordinary properties of small bubbles, particularly those with submicron sizes, could explain the efficient production of the hydrogen rich gas.

用纳秒脉冲在乙醇和甲醇水溶液中产生的直流浸没等离子体，证实了氢气合成气H2 + CO的有效生成。乙醇和甲醇在水中的含量为35%时进行了比较。与乙醇相比，甲醇电解质的合成气生产效率提高约25%。在平均功率为10 W的9 ns 9 kV负直流脉冲下进行的试验证实，H2含量超过65%的合成气产量高达0.5 l/min。在这两种电解质中，实验表明了小气泡在过程中的重要作用。这些气泡明显是由直流脉冲中形成的极短流线产生的。小气泡的非凡特性，尤其是那些亚微米大小的气泡，可以解释富氢气体的高效生产。

The present study is focused on exploring strategies for enhancing electrocatalytic and photocatalytic water splitting kinetics by increasing the density of potential redox-active sites, promoting higher charge separation, and inhibiting self-corrosion during prolonged light-exposure in photocatalysis. In this regard, a highly efficient ternary heterostructure PANI/MXene/MnO₂ (PMM) catalyst was prepared via in-situ polymerization of PANI on MXene/MnO₂ composite and then loaded onto flexible carbon fibre (CF) support using a facile dip-coating method. The obtained PMM/CF heterostructure reveals superior activity in electrochemical water splitting, requiring an overpotential of merely 67 mV and 170 mV to drive hydrogen evolution reaction (HER) and oxygen evolution reaction (OER), respectively, along with a small cell voltage of 1.49 V, contrary to pristine MXene which exhibits high overpotential of 206 mV for HER and remains inactive in OER. Further, in photocatalysis, PMM/CF combined with CdS photo absorber reveals a high photocurrent density of 9.87 mA cm⁻² and photoconversion efficiency of 0.41% due to maximized light absorption and quick charge separation facilitated by a Z-scheme route charge transfer. Thus, this work led to the development of a robust hydrogen-evolving electrode that collectively operates for electrocatalysis and sunlight-driven photocatalysis for sustainable hydrogen production.

本研究的重点是探索通过增加潜在氧化还原活性位点的密度、促进电荷分离和抑制光催化中长时间暴露在光下的自腐蚀来提高电催化和光催化水分解动力学的策略。在此基础上，通过原位聚合法制备了一种高效三元异质结构PANI/MXene/MnO2 （PMM）催化剂，并采用易浸涂法将PANI/MXene/MnO2负载在柔性碳纤维（CF）载体上。得到的PMM/CF异质结构在电化学水分解中表现出优异的活性，分别需要67 mV和170 mV的过电位来驱动析氢反应（HER）和析氧反应（OER），以及1.49 V的小电池电压，而原始MXene在HER中表现出206 mV的高过电位，在OER中保持无活性。此外，在光催化方面，PMM/CF与CdS光吸收剂结合，由于最大的光吸收和Z-scheme路线电荷转移促进的快速电荷分离，其光电流密度达到9.87 mA cm−2，光转换效率为0.41%。因此，这项工作导致了一种强大的析氢电极的发展，该电极共同用于电催化和阳光驱动的光催化，以实现可持续的氢生产。

Fabrication of a nanocomposite with a low-cost and efficient synthesis method instead of using electrocatalysts based on platinum metal has become one of the main challenges in energy storage devices and fuel cells. In this regard, a bifunctional electrocatalyst for supercapacitors and oxygen reduction reaction is fabricated and tested. The novelty of this study is the synthesis method and enhancement of the electrochemical characteristics of synthesized electrocatalysts. The core-shell method is used for the electrocatalyst's synthesis which uses Zeolitic Imidazolate Framework (ZIF)-8, ZIF-67, and Material Institute Lavoisiers (MIL)-101 for the fabrication of three types of electrocatalysts. In the following, to increase the characteristics such as conductivity and stability, doping of Copper (Cu), Cerium (Ce), and Lanthanum (La) are added to the nanocomposites. The Co@NC, CoZn@NC, and CoZn@FeNC prepared electrocatalysts are obtained from the pyrolyze process of La/ZIF-67, CeCu/ZIF-8@ La/ZIF-67, MIL-101@CeCu/ZIF-8/La/ZIF-67. The results indicated that the CoZn@NC electrocatalyst has the best performance in the oxygen reduction reaction (ORR) with an onset potential of 0.062 (V vs Ag/AgCl) and current density of −12.97 (mA/cm²) at a constant voltage of −1 V. Furthermore, the electron transfer number of CoZn@NC electrocatalyst for ORR was 3.64. The conducted Galvanostatic Charge-Discharge (GCD) tests demonstrated that the CoZn@NC electrode has the highest capacitance of 271.14 F/g. The outcomes showed that by the core-shell method, various properties of nanocomposites can be utilized to solve the weaknesses of catalysts by using proper metals. Moreover, the presence of

improve the structural defects in the carbon matrix, the stability based on the chronoamperometry results, and the mass transfer. The study provides a perspective for future researches to fill the research gaps to obtain the new supercapacitors utilize on a large scale in the electronics industry.

利用低成本、高效率的合成方法制备纳米复合材料而不是使用基于铂金属的电催化剂，已成为储能装置和燃料电池的主要挑战之一。为此，制备并测试了一种用于超级电容器和氧还原反应的双功能电催化剂。本研究的新颖之处在于所合成电催化剂的合成方法和电化学特性的提高。采用核壳法合成了三种类型的电催化剂，其中ZIF -8、ZIF-67和材料研究所拉瓦锡(MIL)-101分别制备了三种类型的电催化剂。接下来，为了提高纳米复合材料的导电性和稳定性，我们在纳米复合材料中添加了铜（Cu）、铈（Ce）和镧（La）。通过La/ZIF-67、CeCu/ZIF-8@ La/ZIF-67、MIL-101@CeCu/ZIF-8/La/ZIF-67热解制得Co@NC、CoZn@NC和CoZn@FeNC电催化剂。结果表明，CoZn@NC电催化剂在−1 V恒定电压下，起始电位为0.062 (V vs Ag/AgCl)，电流密度为−12.97 (mA/cm2)，在氧还原反应（ORR）中表现最佳。此外，CoZn@NC电催化剂对ORR的电子转移数为3.64。进行的恒流充放电（GCD）测试表明，CoZn@NC电极的最高电容为271.14 F/g。结果表明，通过核壳方法，可以利用纳米复合材料的各种性能，通过适当的金属来解决催化剂的弱点。此外，Cu2+、Ce3+、La3+的存在改善了碳基体的结构缺陷，提高了碳基体的稳定性和传质性能。该研究为未来的研究提供了一个视角，以填补研究空白，使新型超级电容器在电子工业中大规模应用。

Technology-rich Integrated Assessment Models (IAMs) offer the possibility to endogenously resolve hydrogen demand as a function of competition between technologies to meet energy service demands while considering wider interactions with climate and the economy. Such models are typically configured with relatively low spatial and temporal resolution thereby limiting their utility in studying future global hydrogen trade scenarios. This work presents a framework for the soft-linking of IAM scenarios to a higher spatial and temporal resolution global model. This framework provides an “engine” with which to generate future-looking coupled hydrogen & electricity models with the co-optimization of production capacity, storage, and transmission infrastructure that allow the user to vary key technoeconomic input parameters. The modelling framework is applied to an IAM scenario and validated against the parent IAM. The utility of the model when examining electricity & hydrogen commodity trade in future scenarios is then demonstrated.

Brazil is leveraging its extensive potential in solar, wind, and hydro energy to establish itself on the global map of green hydrogen production—a pivotal component in the ongoing energy transition. The economic viability of green hydrogen hinges on optimal locations with abundant renewable resources, space for solar or wind farms, access to water, and the potential for exporting to major demand centers. In this context, this study evaluates the potential for green hydrogen production in the State of Ceará, Brazil, using multi-criteria decision-making (MCDM) methods, which are designed to prioritize conflicting tangible and intangible criteria to determine the best decision alternatives. The additive ratio assessment (ARAS), simple additive weighting (SAW), combinative distance-based assessment (CODAS), and technique for order performance by similarity to ideal solution (TOPSIS) methods are evaluated for decision-making purposes, with weighting and aggregation relying on the best-worst method (BWM) and ensemble ranking. Criteria considered in the analysis include suitable areas for wind and solar farms, wind and solar energy potentials, water availability, surface temperature, electrical infrastructure, population, and local gross domestic product (GDP).

The perovskite-type hydride compounds are potential candidate materials in the field of hydrogen storage, which is essential for the transition to sustainable energy. This study investigates perovskite-type hydrides MCoH₃ (M = Na, K, Rb) as potential options for hydrogen storage applications by employing density functional theory (DFT). The analysis of formation energy and elastic constants indicates that the MCoH₃ compounds exhibit thermodynamic and mechanical stability. The calculation of Pugh's ratio reveals that these hydrides are brittle materials. Electronic properties reveal that MCoH₃ compounds exhibit metallic characteristics, while KCoH₃ and RbCoH₃ show half-metallic behavior. The phonon dispersion curves confirm dynamic stability. Thermodynamic analysis confirms the material's thermal stability at different temperature ranges. The compounds demonstrate significant gravimetric and volumetric hydrogen storage capacities, with NaCoH₃ exhibiting the highest value of 3.56 wt% and 129.94 g H₂/L, respectively. Optical characteristics suggest strong interactions with electromagnetic radiation. Thus, the study implies that MCoH₃ compounds can be considered for hydrogen storage.

Response surface methodology was employed to establish a thermophilic hydrogen production process from co-substrate of food waste (FW) and waste activated sludge (WAS), resulting in a maximum hydrogen production of 2602.68 ± 54.88 mL/L, which was 5.4 and 21.9 times of FW and WAS, respectively. The co-substrate facilitated the butyrate pathway of hydrogen production and decreased lactate accumulation, and significantly increased the activity of butyric kinase and hydrogenase (p < 0.05). Meanwhile, it could promote microbial growth by creating a more suitable redox environment. Microbial community analysis showed that Thermoanaerobacterium (hydrogen production genus) was specifically enriched and dominant in co-substrate (82.3%). Further functional prediction analysis showed that the co-substrate effectively promoted carbohydrate metabolism. Furthermore, pretreatment improved sludge biodegradability. This study establishes a feasible hydrogen production process, profoundly revealed the mechanism of enhanced anaerobic fermentation from the perspective of microbial growth and metabolism, which lays solid foundation on the hydrogen production from waste biomass.

To address the rising demand for hydrogen energy and its reliance with the water sector, this study presents an optimal scheduling framework for a multi-energy microgrid (MEMG) that integrates electric, thermal, water, and hydrogen energy networks. To this end, a mixed-integer linear programming (MILP) model is formulated to minimize both operational costs and emissions. A bi-variate piecewise McCormick envelope technique is utilized to manage the non-linear constraints associated with the water network. The model also incorporates the transportation sector, including electric and hydrogen vehicles (EVs, HVs), with vehicle-to-grid (V2G) technology, and models their associated uncertainties using Monte Carlo simulation (MCS). Additionally, the sale of oxygen as a by-product of the hydrogenation process is also considered. The case study shows significant economic and environmental benefits, with a 29.66% cost reduction and 22.26% emissions decrease from water network integration. Oxygen sales further reduce costs by 14.19%, and V2G technology contributes an additional 2.35% cost and 6.01% emissions reduction. The proposed linear approximation method achieved superior performance, with a root mean square error (RMSE) of 0.72 and a relative error of 2.132%.
