This study presents a comprehensive techno-economic-environmental analysis of integrating hydrogen into Dutch heating networks to enhance seasonal storage and reduce CO₂ emissions. A hybrid solar–wind–hydrogen system is proposed, comprising photovoltaic panels, wind turbines, a battery energy storage system, a proton exchange membrane electrolyzer, hydrogen compression and storage units, a proton exchange membrane fuel cell, and a water-to-water heat pump. An adaptive peak-shaving controller is developed to govern the battery energy storage system, dynamically limiting grid import peaks while directing surplus renewable electricity to hydrogen production; its application results in a 72 % reduction in the highest observed peak. The system is tested for the city of Enschede, where the controller enables the battery to support peak shaving and coordinates the routing of excess renewable electricity toward green hydrogen generation, which is stored and later used in cold spells. A deep learning-assisted optimization framework, combined with a genetic algorithm, significantly reduces computational costs while accurately predicting system performance. The results show that hydrogen enables seasonal storage, achieving an exergy efficiency of 35.04 %, a total cost rate of 4.84 €/h (5.24 $/h), annual CO₂ emissions of 63.64 tons, a levelized cost of hydrogen of 6.48 €/kg, and a 42.21 % share of the heat supply mix during cold spells.

本研究提出了一项全面的技术、经济和环境分析，将氢气整合到荷兰的供热网络中，以增强季节性储存并减少二氧化碳排放。提出了一种混合太阳能-风-氢系统，包括光伏板、风力涡轮机、电池储能系统、质子交换膜电解槽、氢气压缩和存储单元、质子交换膜燃料电池和水对水热泵。开发了一种自适应调峰控制器，对电池储能系统进行动态限制，将多余的可再生电力用于制氢；它的应用使最高观测峰降低了72%。该系统在恩斯赫德市进行了测试，在那里，控制器使电池能够支持调峰，并协调多余的可再生电力向绿色氢发电的路线，这些电力被储存起来，以后在寒冷时期使用。深度学习辅助优化框架与遗传算法相结合，在准确预测系统性能的同时显著降低了计算成本。结果表明，氢气能够实现季节性储存，实现了35.04%的能源效率，4.84欧元/小时（5.24美元/小时）的总成本率，年二氧化碳排放量为63.64吨，氢气的平准化成本为6.48欧元/公斤，在寒冷时期的供热组合中占42.21%的份额。

Graphene-based single-atom catalysts (G-SACs) have been demonstrated to have significant role in enhancing the hydrogen storage performance of MgH₂. In this work, single Ti atom was incorporated in various modified graphene, including pristine graphene (G), graphene with single vacancy (SVG) and double vacancy (DVG), and N-decorated graphene with single vacancy (N3G) and double vacancy (N4G). The effects of coordination environments of the Ti-decorated G-SACs on the dehydrogenation properties of MgH₂ were systematically investigated by first-principles calculations based on MgH₂/G-SACs heterojunction model. It was found that the defective graphenes can prevent Ti atoms from agglomeration, whereas pristine graphene fails to do so. Structural analysis reveals that the introduction of Ti-decorated G-SACs induces elongation of Mg–H bonds and reduction of effective charge of H atoms at the interface, suggesting the Mg–H bonds tend to weaken. As for dehydrogenation thermodynamics, it was found that Ti-decorated G-SACs reduce the hydrogen desorption energies of MgH₂, with the most significant effect observed for the G-SAC with N3G coordination environment (Ti@N3G). Interestingly, Ti@N3G also poses the greatest enhancement effect on the hydrogen diffusion kinetics, as revealed by ab initio molecular dynamics simulation, indicating that the MgH₂/Ti@N3G interface serves as a fast diffusion channel for H atoms.

石墨烯基单原子催化剂（G-SACs）在提高MgH2储氢性能方面具有重要作用。在这项工作中，将单个Ti原子掺入到各种改性石墨烯中，包括原始石墨烯(G)、单空位石墨烯（SVG）和双空位石墨烯（DVG），以及单空位（N3G）和双空位（N4G）的n修饰石墨烯。基于MgH2/G-SACs异质结模型，采用第一性原理计算方法系统研究了ti修饰G-SACs配位环境对MgH2脱氢性能的影响。研究发现，有缺陷的石墨烯可以防止钛原子聚集，而原始的石墨烯则不能。结构分析表明，ti修饰的G-SACs的引入导致Mg-H键的延伸和界面处H原子有效电荷的降低，表明Mg-H键有减弱的趋势。在脱氢热力学方面，ti修饰的G-SAC降低了MgH2的氢解吸能，其中对N3G配位环境下的G-SAC影响最为显著（Ti@N3G）。有趣的是，通过从头算分子动力学模拟，Ti@N3G对氢扩散动力学的增强作用也最大，这表明MgH2/Ti@N3G界面是氢原子的快速扩散通道。

Selective electrocatalytic glycerol (GLY) reforming to valuable formic acid (FA) is promising yet challenged by high energy barriers in C–C cleavage and C–O coupling. Ni-based catalysts show great potential via generating active high-valence Ni sites, yet their performance remains below industrial needs. To facilitate the rational design and development of high-performance Ni-based catalysts for the GLY oxidation reaction (GOR), we present a comprehensive review of recent breakthroughs in engineering Ni-based electrocatalysts to enhance selective FA production. This review systematically examines the fundamental reaction mechanisms of GOR, the intrinsic advantages and limitations of Ni-based catalysts, and innovative strategies for optimizing their catalytic performance through structural modifications. Specifically, the review also discusses representative strategies including electronic structure engineering, defect engineering, and bimetallic synergistic effects, which collectively aim to improve both activity and selectivity for GOR. Finally, the review is concluded by outlining key challenges and future perspectives in advancing Ni-based electrocatalysts for practical GOR applications.

Although LiAlH₄ is a promising hydrogen storage material, its practical commercial application remains hindered by a high hydrogen desorption energy barrier and sluggish dehydrogenation dynamics. To improve its hydrogen release properties, we use the first-principles calculation to investigate the influence of transition metal (TM) doping on the hydrogen desorption behavior, electronic and optical properties of the LiAlH₄(100) surface. Based on the structural feature of the [AlH₄] group, four hydrogen desorption sites are considered. The results indicate that all TM-doping improve the thermodynamic stability of the system, with Co-doping exhibits the better structural stability. Importantly, all TM-doping significantly reduces the hydrogen desorption energy of the LiAlH₄(100) surface. Co-doping has the lowest energy barrier at the H_A site, showing the most excellent catalytic activity, indicating that Co-doping has the best effect on promoting hydrogen release. Essentially, the reduction in hydrogen desorption energy is that the TM-doping weakens the hybridization between Al-p and H-s states, which weakens the bond strength of Al–H bond in the [AlH₄] group and is beneficial to hydrogen atom desorption. Furthermore, although the TM-doped LiAlH₄ still maintains the ultraviolet response properties, its absorption edge shows a significant redshift phenomenon, indicating an extended optical response range. Therefore, we believe that Co-doping not only effectively reduces the hydrogen desorption barrier on the LiAlH₄(100) surface but also enhances dehydrogenation dynamics, providing a possible path for promoting the commercial application of LiAlH₄-based hydrogen storage material.

虽然LiAlH4是一种很有前途的储氢材料，但它的实际商业应用仍然受到氢解吸能垒高和脱氢动力学缓慢的阻碍。为了提高LiAlH4（100）表面的氢释放性能，我们利用第一性原理计算研究了过渡金属（TM）掺杂对LiAlH4（100）表面氢解吸行为、电子和光学性能的影响。根据[AlH4]基团的结构特点，考虑了4个氢脱附位点。结果表明，所有tm掺杂都提高了体系的热力学稳定性，其中共掺杂表现出更好的结构稳定性。重要的是，所有tm掺杂都显著降低了LiAlH4（100）表面的氢解吸能。共掺杂在HA位点的能垒最低，表现出最优异的催化活性，说明共掺杂促进氢释放的效果最好。从本质上讲，脱氢能的降低是tm掺杂削弱了Al-p态和H-s态之间的杂化，使[AlH4]基团中Al-H键的键强减弱，有利于氢原子的脱附。此外，虽然掺杂tm的LiAlH4仍然保持了紫外响应特性，但其吸收边缘出现了明显的红移现象，表明其光学响应范围扩大。因此，我们认为共掺杂不仅可以有效地降低LiAlH4（100）表面的氢解吸屏障，还可以增强脱氢动力学，为促进LiAlH4基储氢材料的商业应用提供了可能的途径。

This paper investigates the thermodynamic efficiency of hydrogen electrolysis systems and addresses especially the frequent use of a simplified thermoneutral cell voltage value of U_th = 1.481 V, which can lead to erroneous results. The analysis shows that significant deviations occur, particularly in systems with low operating pressure, which is problematic since these technologies are pursued by several manufacturers. To close this research gap, a methodological approach to correctly calculate efficiency is presented. The paper outlines the basic principles of efficiency calculation, the derivation of a polynomial function to determine the thermoneutral cell voltage with high accuracy, and the structure of a COMSOL simulation model. This innovative approach provides a precise and user-friendly solution for simplifying and enhancing the accuracy of efficiency calculations. In addition, further influencing factors are illustrated using an example to enable a well-founded comparison of electrolysis processes. The findings are compared and discussed, providing both improved understanding of electrolysis thermodynamics and a critical perspective on common assumptions in the literature.

The global shift towards sustainable energy underscores the critical role of green hydrogen. Hybrid hydrogen production systems, which integrate alkaline (AEL) and proton exchange membrane (PEMEL) electrolyzers, offer a promising solution for utilizing intermittent renewable power. However, their complex structure and dynamic operation pose significant challenges for fault detection and diagnosis. This paper proposes a Dynamic Deep Coupled Dictionary Learning (DDCDL) method to address these issues. The approach constructs a Unified Joint Dictionary to fuse multimodal AEL and PEMEL data for integrated diagnostics, a Dynamic Adaptive Dictionary updated via online learning to minimize false alarms during operational transitions, and a Deep Sparse Dictionary combined with a temporal convolutional network to enhance sensitivity to incipient faults. Validated with data from a 100 MW wind-solar hydrogen demonstration project, the method demonstrates superior detection timeliness, accuracy, and robustness across single faults, coupled faults, mode-switching faults, and early weak faults compared to established techniques. This work provides an effective technical pathway to improve the operational reliability and economic efficiency of hybrid hydrogen production systems.

This work introduces a novel optimization framework that jointly sizes and dispatches a photovoltaic (PV)–electrolyzer–e-fuel plant while it bids into US day-ahead and real-time electricity markets. The proposed model includes both investment and operational decisions and explicitly values policy levers. A multi-scenario analysis evaluates the impact of operational constraints, which include renewable-only hydrogen production, grid import restrictions, and arbitrage limits, demonstrating that flexibility in grid interaction is critical for investment viability. Dispatch results reveal that electrolyzer operation is highly responsive to real-time price fluctuations, which leverage low-price periods for cost-effective hydrogen production. A structured sensitivity analysis spanning CO

_{2}

credit levels ($0–400/t) and hydrogen production subsidies ($0–50/MWh), evaluated across multiple operating scenarios, identifies three key findings: (i) investment is not triggered until the CO

_{2}

这项工作引入了一个新的优化框架，该框架在光伏(PV) -电解槽-电子燃料工厂在美国日前和实时电力市场投标时，联合对其进行规模和调度。所建议的模型包括投资和操作决策，并明确地重视政策杠杆。一项多情景分析评估了运营限制的影响，包括可再生氢生产、电网进口限制和套利限制，表明电网互动的灵活性对投资可行性至关重要。调度结果显示，电解槽运行对实时价格波动的反应非常灵敏，从而利用低价期实现具有成本效益的制氢。通过对二氧化碳信用额度（0-400美元/吨）和氢气生产补贴（0-50美元/兆瓦时）的结构化敏感性分析，对多种运营情景进行了评估，确定了三个关键发现：(i)在二氧化碳信用额度超过约200美元/吨之前，不会触发投资；（ii）超过这个门槛，适度补贴提高盈利能力，并支持50MW电解槽和30mw电甲醇和20mw甲烷；（三）禁止电网进口或套利充分抑制了投资，强调了运营灵活性的必要性。所有分析均采用从NYISO市场和操作数据库中获取的每日实时价格数据，以确保市场驱动评估的可重复性和透明度。

Mo₂C-based electrocatalysts are widely used in electrocatalytic hydrogen evolution reaction (HER) because of their excellent catalytic activity and strong stability. In this work, N,P–Mo₂C@rGO, a reduced graphene oxide–loaded Mo₂C heterostructure codoped with N and P, was designed as a highly efficient HER electrocatalyst on the basis of the doping of nonmetallic elements, engineering of defects, and construction of special heterostructures. The doping of N and P can efficiently fill up unoccupied d-orbitals in Mo, thus modulating the electronic structure of Mo₂C. Moreover, the use of carbon vacancies for defect engineering can effectively modulate the local charge and stability of the catalyst. The local charge distribution and electronic structure of N,P–Mo₂C@rGO can be regulated to optimize ΔG_H*. In addition, the specific surface area of N,P–Mo₂C@rGO can be significantly increased through the “Hemisphere–Net” synergistic effect. In this effect, hollow hemispheres formed through the aggregation of Mo₂C nanoparticles can remarkably expand the specific surface area of the catalyst to provide additional active sites, and the heterostructure formed by the rGO substrate (“Net”) and Mo₂C can promote electron transfer to improve the efficiency of electrocatalytic HER. Meanwhile, DFT calculations revealed that N,P–Mo₂C@rGO significantly reduced the Mo–H* bond strength of Mo₂C and optimized the free energy of hydrogen adsorption. Specifically, in 1.0 M KOH and 0.5 M H₂SO₄, N,P–Mo₂C@rGO had overpotential values of 102 and 141 mV, respectively, and Tafel slopes of 86 and 88 mV·dec⁻¹, respectively. This study provides a reference for the design of efficient electrocatalysts with special structures and defect engineering.

mo2c基电催化剂具有优异的催化活性和较强的稳定性，在电催化析氢反应（HER）中得到了广泛的应用。在本研究中，N，P - Mo2C@rGO是一种与N和P共掺杂的还原氧化石墨烯负载Mo2C异质结构，在非金属元素掺杂、缺陷工程和特殊异质结构构建的基础上，被设计成一种高效的HER电催化剂。N和P的掺杂可以有效地填充Mo中未占据的d轨道，从而调节Mo2C的电子结构。此外，利用碳空位进行缺陷工程可以有效地调节催化剂的局部电荷和稳定性。可以调节N，P - Mo2C@rGO的局部电荷分布和电子结构以优化ΔGH*。此外，通过“半球-网”协同效应，N，P - Mo2C@rGO的比表面积显著增加。在这种效应下，Mo2C纳米颗粒聚集形成的空心半球可以显著扩大催化剂的比表面积，从而提供额外的活性位点，而rGO底物（“Net”）与Mo2C形成的异质结构可以促进电子转移，从而提高电催化HER的效率。同时，DFT计算表明，N，P - Mo2C@rGO显著降低了Mo2C的Mo-H *键强度，优化了吸附氢的自由能。在1.0 M KOH和0.5 M H2SO4条件下，N、P - Mo2C@rGO的过电位值分别为102和141 mV， Tafel斜率分别为86和88 mV·dec−1。该研究为特殊结构高效电催化剂的设计和缺陷工程提供了参考。

The interest in hydrogen production is higher than ever due to its key role as carbon-free energy carrier. In this work we propose a concept of electrified Steam Methane Reforming (e-SMR) reactor where a directly Joule-heated silicon infiltrated silicon carbide (SiSiC) foam provides heat to catalytic pellets packed inside the foam openings. All the advantages associated with a pelletized catalyst are maintained while a close coupling of heat generation by the foam with heat consumption by the catalytic reaction is guaranteed. An experimental campaign demonstrated the intensification potential of the reactor, which achieved specific power inputs up to 10 MW/m³ and specific energy consumptions of 1.33 kWh/Nm³_H2.

A 2-D heterogeneous mathematical model was validated against the experimental data while a strategy based on sectioning the foam into several slices electrically connected in series is proposed to meet the requirements of low pressure drops and high electric circuit resistances necessary in scaled up units.

由于氢气作为无碳能源载体的关键作用，人们对氢气生产的兴趣比以往任何时候都高。在这项工作中，我们提出了一种电气化蒸汽甲烷重整（e-SMR）反应器的概念，其中直接焦耳加热的硅渗透碳化硅（SiSiC）泡沫为填充在泡沫开口内的催化颗粒提供热量。与球团化催化剂相关的所有优点都得到了保持，同时保证了泡沫产生的热量与催化反应消耗的热量的密切耦合。实验证明了该反应器的强化潜力，其比功率输入高达10 MW/m3，比能耗为1.33 kWh/Nm3H2。根据实验数据验证了二维非均匀数学模型，并提出了一种基于将泡沫切割成若干片串联电连接的策略，以满足放大装置所需的低压降和高电路电阻的要求。

The development of stable and exceptional hydrogen evolution reaction electrocatalysts plays an essential role in decreasing the carbon footprint and keeping the planet green and salubrious. Fabrication of transition metal-single atoms (TM-SA) on various substrates, such as transition metal compounds and carbon materials, is a potential solution in advancing efficient electrodes for HER due to maximized atomic utilization, creating a synergistic effect, tunable electronic properties, and reduced metal loading. Their atomically dispersed active sites provide unique coordination environments and optimized adsorption energy of intermediates, enabling TM-SAs to outperform conventional electrocatalysts. This review presents the latest works on SA-based electrocatalysts for HER. We describe various pathways for HER, then explore the different fabrication processes of SA-based catalysts. Moreover, noble metals SA (Pt, Ru, Pd SA), non-noble metals SA (Co, Ni, Mo SA), and their combination related to electrocatalysts for HER are discussed. Ultimately, the specific limitations and future perspectives for advancing TM-SA-based HER electrocatalysts were manifested.
