An agrivoltaic system combines energy production and agricultural crops in one location, addressing the growing demand for sustainable and cost-effective energy sources. The objectives of this bibliometric analysis are to identify knowledge gaps, emphasize important contributions, and highlight trends in agrivoltaic research. It is expected to support creative research in agriculture and sustainable energy, foster collaborations, and inform decision-making. This study thus employed the systematic, bibliometric and content analysis review approach to analyse research works published on the topic during the last two decades. Data from the Scopus database was used for the qualitative and quantitative analysis using the Biblioshiny package in R and VOSviewer software. The study analysed 155 documents, revealing an 18.21% annual growth in research on agrivoltaics. The most frequently used keyword was agrivoltaics, highlighting its potential for sustainability and sustainable land use. Research on the topic is found to be evolving from small-scale irrigation power generation to large-scale electricity generation, emphasizing dual land use for energy and food production. North Carolina State University and Chinese institutions are leading in agrivoltaics research. The study concluded with some identified research gaps that should be examined going into the future.

Accurately assessing the potential of wind and PV power is crucial in achieving the 2 °C climate target. Biased assessments will lead to flawed decisions by national governments and related industries, resulting in significant economic and social losses and energy waste. In this study, meta-analysis is used to identify and discuss the factors that affect the differences in existing wind power and PV potential evaluations at national and provincial scales in China. The present study delves into the geographical, technical, and economic potential, exploring the impact of the scenery complementary portfolio on future development trends. Results show that the primary factors affecting geographic potential are meteorological datasets and land use. Regarding technical potential, the hub height, turbine power rating, and rotor diameter appear as the key drivers of wind turbine power generation efficiency and effectiveness. As far as solar panel power generation is concerned, tilt angle and PV cell efficiency are the main influencing factors, with environmental factors having a more significant impact on PV technical potential than technical parameters. The study establishes a reference database for data use, providing a reliable reference basis for strategic planning decisions and improving the accuracy of future potential wind power/PV variability assessments.

准确评估风能和光伏发电的潜力对于实现 2 °C 的气候目标至关重要。偏颇的评估将导致各国政府和相关行业做出错误的决策，造成重大的经济和社会损失以及能源浪费。本研究采用元分析法来识别和讨论影响中国国家和省级现有风电和光伏发电潜力评估差异的因素。本研究深入探讨了地理、技术和经济潜力，探讨了风光互补组合对未来发展趋势的影响。结果表明，影响地理潜力的主要因素是气象数据集和土地利用。在技术潜力方面，轮毂高度、涡轮机额定功率和转子直径似乎是风力涡轮机发电效率和效益的主要驱动因素。就太阳能电池板发电而言，倾斜角度和光伏电池效率是主要影响因素，环境因素对光伏技术潜力的影响比技术参数更为显著。该研究建立了数据使用参考数据库，为战略规划决策提供了可靠的参考依据，并提高了未来潜在风能/光伏变异性评估的准确性。

Biodiesel is acknowledged as the most appropriate biofuel to decarbonise the transport sector and combat climate change. The ever-increasing biodiesel production via transesterification results in large amount of glycerol (e.g., 10 kg of glycerol for every 100 kg of biodiesel). Converting glycerol into value-added goods is perceived to be a viable way to lower the high cost of producing biodiesel and expand its market share. The current study examines the technical and environmental aspects of bio-hydrogen, bio-syngas, acrolein, propylene glycol, epichlorohydrin, bio-methanol and bio-ethanol synthesis. CHEMCAD process simulation software was used to perform the modelling and simulation aspects considering a glycerol flowrate of 100 kg/h. The environmental study is based on primary and secondary data and is carried out using the Life Cycle Assessment methodology and the LCA for Experts software, using ReCiPe as the impact assessment method. The technical evaluation points towards glycerol conversion to propylene glycol and bio-methanol production as the best approaches given the relatively low energy requirements, increased purity (>97 wt%) and steadily growing product market. Bio-methanol exhibits the best environmental performance among all examined scenarios, providing the lowest impact in eight out of eleven categories studied while placing second in terms of FETP impact. Glycerol conversion towards propylene glycol seems as the second-best conversion route as it generates the lowest score in regards to GWP impact (0.31 kg CO₂ eq./ kg_product). Ultimately, the most effective methods for valorizing glycerol and improving the production of biodiesel by lowering the expenses related to its manufacturing are glycerol reforming toward bio-methanol and propylene glycol.

生物柴油是公认的最适合运输行业脱碳和应对气候变化的生物燃料。通过酯交换法生产的生物柴油不断增加，产生了大量甘油（例如，每 100 千克生物柴油产生 10 千克甘油）。将甘油转化为增值产品被认为是降低生物柴油生产的高成本并扩大其市场份额的可行方法。本研究探讨了生物氢、生物合成气、丙烯醛、丙二醇、环氧氯丙烷、生物甲醇和生物乙醇合成的技术和环境问题。考虑到甘油流量为 100 公斤/小时，使用 CHEMCAD 工艺模拟软件进行建模和模拟。环境研究以第一手和第二手数据为基础，采用生命周期评估方法和 LCA for Experts 软件，以 ReCiPe 作为影响评估方法。技术评估结果表明，甘油转化为丙二醇和生物甲醇生产是最佳方法，因为它们的能源需求相对较低，纯度更高（97 wt%），产品市场稳步增长。在所有研究方案中，生物甲醇的环境绩效最佳，在研究的 11 个类别中，生物甲醇对 8 个类别的影响最小，而在 FETP 影响方面，生物甲醇位居第二。甘油转化为丙二醇似乎是第二好的转化途径，因为它在全球升温潜能值影响方面得分最低（0.31 千克二氧化碳当量/千克产品）。归根结底，甘油转化为生物甲醇和丙二醇是最有效的甘油增值方法，也是通过降低生物柴油生产成本来提高生物柴油产量的最有效方法。

Hydrogen storage poses a major challenge to mobile, stationary, and portable energy in better serving a low-carbon economy and sustainable future of humankind. Existing hydrogen storage methods are typical of low storage capacity, complicated storage technology, high capital cost, great storage risk, and excess carbon emissions. Here, the hydrogen clathrate hydrate in powdered-ice Ih (HCHinIh) is empirically synthesized at relatively lower pressures from ∼6.3–12.9 MPa and relatively higher temperatures from ∼243–273 K for innovative hydrogen storage, building on lessons from the enclathration of the air clathrate hydrates that naturally formed in polar ice sheets. As a result, the enclathration for HCHinIh is forced by the dynamical evolution of bubbles under the quasi-densification of powdered-ice Ih. In addition, the estimated hydrogen storage capacity of 3.44 wt% for the HCHinIh is comparable to, or even far higher than those from the existential hydrogen storage technologies, and the potential to be improved by upgrading the designed synthesis apparatus for the HCHinIh. Thus, this work paves a novel route by mimicking Nature to advance hydrogen storage via synthesizing the HCHinIh in achieving higher storage capacity, simpler storage technology, lower capital cost, less storage risk, as well as net zero-carbon emissions.

为更好地服务于低碳经济和人类可持续发展的未来，储氢对移动、固定和便携式能源提出了重大挑战。现有的储氢方法存在储氢能力低、储氢技术复杂、资金成本高、储氢风险大、碳排放超标等问题。在此，我们借鉴极地冰原中自然形成的空气水合物飞升的经验，在 6.3-12.9 兆帕的相对较低压力和 243-273 K 的相对较高温度下合成了粉末冰 Ih 中的氢水合物（HCHinIh），用于创新性储氢。因此，在冰粉 Ih 准致密化条件下，气泡的动态演化迫使 HCHinIh 非气化。此外，估计 HCHinIh 的储氢能力为 3.44 wt%，与现有的储氢技术相当，甚至远远高于现有的储氢技术。因此，这项工作为通过合成 HCHinIh 来模拟自然界以实现更高的储氢容量、更简单的储氢技术、更低的资本成本、更小的储氢风险以及净零碳排放来推进储氢技术铺平了一条新路。

Dead-end anode and recirculation cathode is an operating mode effectively improving the gas reactant utilization of hydrogen–oxygen proton exchange membrane fuel cell (H₂/O₂ PEMFC) stack. However, the difference of single cells in the stack, will be further expanded due to the flooding and impurities and necessary purge for removing them. In this work, the voltage uniformity and stability of H₂/O₂ PEMFC under different operating conditions are investigated based on a dead-end anode and recirculation cathode PEMFC stack. Research indicates that enhancing the current density and temperature, lowering the inlet gas pressure will diminish the uniformity in stack voltage. The analysis of the experimental pattern reveals a positive correlation between the voltage uniformity and stability. This is due to the water flooding or membrane dehydration phenomenon of the single-cell leading to a reduction of the single-cell voltage and the voltage uniformity of the stack, while the water flooding or membrane drying phenomenon makes the stack more unstable and the purge interval shorter. Based on these experimental results, the best operating scheme for the designed stack is proposed, which is of some guidance and reference value for the practical application of air-cooled PEMFC in the hundred-watt class.

死端阳极和再循环阴极是一种运行模式，可有效提高氢氧质子交换膜燃料电池（H2/O2 PEMFC）堆的气体反应物利用率。然而，堆栈中单个电池的差异将进一步扩大，原因是存在水浸和杂质，需要清除杂质。在这项工作中，基于死端阳极和再循环阴极 PEMFC 堆，研究了 H2/O2 PEMFC 在不同工作条件下的电压均匀性和稳定性。研究表明，提高电流密度和温度、降低入口气体压力会降低堆栈电压的均匀性。对实验模式的分析表明，电压均匀性和稳定性之间存在正相关。这是由于单电池的水浸或膜脱水现象导致单电池电压和堆栈电压均匀性降低，而水浸或膜干燥现象使堆栈更不稳定，吹扫间隔更短。根据这些实验结果，提出了所设计电堆的最佳运行方案，对百瓦级空冷 PEMFC 的实际应用具有一定的指导和参考价值。

Depleted hydrocarbon reservoirs are considered as the most feasible option for CO₂ geological sequestration and utilization. Most of the hydrocarbon reservoirs are naturally fractured. Simulation of fluid flow and heat transfer in these fractured formations remains a significant challenge in reservoir engineering. In this study, a dual-continuum model is developed to simulate integrated CO₂ sequestration and CO₂-circulated geothermal extraction in a fractured reservoir block in North Oman. The high-dimensional sensitivity of key parameters controlling CO₂-brine flow and heat transfer in this matrix-fracture system is quantitatively evaluated by an efficient surrogate modeling approach. The surrogate models are constructed and validated based on a suite of physics-based model simulations. It is found that fracture permeability dominates the CO₂ injectivity, storage, circulation and associated geothermal extraction. Response surface analysis shows that the flow area density between matrix-fracture and matrix block length controls the flux interaction between matrix and fracture formations. In contrast, the fracture aperture shows negligible influence in the dual-continuum modeling system. Particularly, sensitivity varying with locations on the response surface is analyzed for defined performance indicators.

枯竭碳氢化合物储层被认为是二氧化碳地质封存和利用的最可行方案。大多数碳氢化合物储层都是天然裂缝。模拟这些裂缝地层中的流体流动和传热仍然是储层工程中的一项重大挑战。本研究开发了一个双连续模型，用于模拟北阿曼一个断裂储层区块中的二氧化碳封存和二氧化碳循环地热开采综合过程。通过高效的代理建模方法，对控制该基质-裂缝系统中二氧化碳-盐水流动和热传递的关键参数的高维敏感性进行了定量评估。代用模型是在一套基于物理的模型模拟基础上构建和验证的。研究发现，断裂渗透性主导着二氧化碳的注入、储存、循环和相关地热提取。响应面分析表明，基质-裂缝之间的流动区域密度和基质块长度控制着基质和裂缝地层之间的通量相互作用。相比之下，裂缝孔径在双连续建模系统中的影响可以忽略不计。特别是，针对确定的性能指标，分析了随响应面上不同位置而变化的敏感性。

Energy technology assessment is a systematic evaluation of energy technologies, making it relevant in energy transition research. However, trends in energy technology assessment research remain largely unknown. Combining a bibliometric and content analysis of some key documents, this study explored the conceptual evolution of 2438 documents in energy technology assessment published from 1976 to 2023. The study used the Scopus database to collect data and analysed using Biblioshiny in RStudio, VosViewer and Microsoft Excel. The results show that ‘energy technology assessment’ has not developed as a unique field and remains rooted in the ‘technology assessment’ research. The annual growth rate of publications assessing energy technologies was 10.5% during the analysis period. One hundred and sixteen countries have contributed to the energy technology assessment research. The co-occurrence analysis results revealed four broad themes: ‘sustainable development’, ‘energy transition technologies’, ‘technology assessment methods’ and ‘energy system’. Surprisingly, the keyword ‘energy transition’ minimally features in the sampled documents but seems to be emerging.

The air supply subsystem is crucial for optimizing proton exchange membrane fuel cells (PEMFCs). This study develops a transient model for the air subsystem and proposes a control strategy that decouples air pressure and flow using sliding mode-active disturbance rejection control (SM-ADRC). In this study, adjustments to the air compressor speed and the opening of the back-pressure valve are utilized to achieve this control strategy. The sliding mode-extended state observer (SM-ESO) is employed to estimate and compensate for uncertainties within the system, while the sliding mode-nonlinear state error feedback (SM-NLSEF) is used to simultaneously control air flow and pressure. The study evaluates the performance of the SM-ADRC controller across various scenarios and environmental pressures. Evaluations show that the SM-ADRC controller significantly outperforms traditional methods like Fuzzy-ADRC, ADRC, SMC, and PID, with overshoot reductions of 18.2%, 34.1%, 42.5%, and 63.7%, respectively, and adjustment time under 1 s. Additionally, SM-ADRC achieves a 4.1% and 1.8% improvement in efficiency compared to PID and ADRC.

供气子系统对于优化质子交换膜燃料电池（PEMFC）至关重要。本研究为空气子系统建立了一个瞬态模型，并提出了一种利用滑动模式主动干扰抑制控制（SM-ADRC）将空气压力和流量分离的控制策略。在本研究中，通过调整空气压缩机的转速和背压阀的开度来实现这一控制策略。滑动模式扩展状态观测器（SM-ESO）用于估计和补偿系统内的不确定性，而滑动模式非线性状态误差反馈（SM-NLSEF）则用于同时控制空气流量和压力。研究评估了 SM-ADRC 控制器在各种情况和环境压力下的性能。评估结果表明，SM-ADRC 控制器的性能明显优于模糊-ADRC、ADRC、SMC 和 PID 等传统方法，过冲分别减少了 18.2%、34.1%、42.5% 和 63.7%，调整时间也少于 1 秒。

The current study examines the absorption performance of the embedded cooling tubes (ECT) and helically coiled tubes (HCT) reactor geometries by keeping the contact surface area and heat exchanger volume identical to determine the bettered bed configuration based on specific heat extraction rate (SHER) and 90 % saturation time. The ECT (comprising sixty straight tubes) and HCT (comprising three helical tubes) of the same diameter (4.75 mm), heat exchange volume (90477 mm³), and contact surface area with the hydride (45245 mm³) are subjected to variations in supply pressure (5, 15, 25 bar), water inlet temperature (278, 288, 298 K), and flow rate (0.1, 0.5, 0.9 kg/s). The HCT reactor demonstrated superior performance to the ECT reactor concerning hydrogen supply pressure, reducing absorption time by 1.5 to 1.6 times. Variations in water inlet temperature resulted in HCT highlighting 34–38 % faster absorption than ECT for an equivalent quantity of hydrogen absorbed. The mass flow rate indicated that absorption was, on average, 30 % faster for HCT compared to ECT. In conclusion, it was observed that the SHER of HCT is nearly double that of ECT across all operating conditions, thus emphasizing the beneficial aspect of utilizing helically coiled tubes.

本研究在保持接触表面积和热交换器体积相同的情况下，考察了嵌入式冷却管（ECT）和螺旋盘绕管（HCT）反应器几何结构的吸收性能，从而根据比热萃取率（SHER）和 90% 饱和时间确定更好的床层配置。ECT（由六十根直管组成）和 HCT（由三根螺旋管组成）的直径（4.75 毫米）、热交换体积（90477 立方毫米）以及与氢化物的接触表面积（45245 立方毫米）相同，但供应压力（5、15、25 巴）、进水温度（278、288、298 K）和流速（0.1、0.5、0.9 千克/秒）各不相同。在供氢压力方面，HCT 反应器的性能优于 ECT 反应器，吸收时间缩短了 1.5 至 1.6 倍。进水温度的变化导致在吸收等量氢气的情况下，HCT 的吸收速度比 ECT 快 34-38%。质量流量表明，与 ECT 相比，HCT 的吸收速度平均快 30%。总之，在所有操作条件下，HCT 的 SHER 都几乎是 ECT 的两倍，从而强调了使用螺旋盘绕管的益处。

Air pollution is recognized as a critical environmental challenge impacting humanity, with factors such as population growth, industrial expansion, and increased use of motorized vehicles contributing to its worsening. Presently, developing nations like Iran, particularly cities such as Tehran, grapple with severe air pollution issues exacerbated by the heavy reliance on fossil fuels. This research introduces a solar power system integrating an Organic Rankine Cycle (ORC) unit to generate electricity while concurrently addressing air pollution concerns. A novel solar dish concentrator featuring a vacuum cylindrical cavity receiver was studied optically and thermally in Tehran, Iran, from 2001 to 2022. The investigation also analyzed the emission reduction potential and land requirements for implementing the solar ORC system. The results indicated that employing the ORC system with a vacuum cavity receiver offers a more effective solution for reducing CO₂ emissions and enhancing environmental conditions. To satisfy 10% of Tehran’s industrial power demand in 2022, the solar ORC system required about 459 ha of land for the vacuum cylindrical receiver, whereas the non-vacuum cylindrical receiver necessitated approximately 538 ha. In essence, developing this solar ORC system could lead to a carbon mitigation of 1,676,641.50 tons of CO₂ and generate carbon credits valued at $24,311,287.31. Ultimately, the proposed solar ORC system holds significant promise in advancing energy governance by establishing innovative power plant systems.

空气污染被认为是影响人类的一个关键性环境挑战，人口增长、工业扩张和机动车使用量增加等因素都导致了空气污染的恶化。目前，伊朗等发展中国家，尤其是德黑兰等城市，因严重依赖化石燃料而加剧了严重的空气污染问题。本研究介绍了一种集成有机郎肯循环（ORC）装置的太阳能发电系统，在发电的同时解决空气污染问题。2001 年至 2022 年期间，在伊朗德黑兰对一种具有真空圆柱腔接收器的新型太阳能碟形聚光器进行了光学和热学研究。调查还分析了实施太阳能 ORC 系统的减排潜力和土地需求。结果表明，采用真空空腔接收器的 ORC 系统为减少二氧化碳排放和改善环境条件提供了更有效的解决方案。为满足德黑兰 2022 年 10%的工业电力需求，太阳能 ORC 系统的真空圆柱形接收器需要约 459 公顷的土地，而非真空圆柱形接收器需要约 538 公顷的土地。从本质上讲，开发该太阳能 ORC 系统可减少 1,676,641.50 吨二氧化碳，并产生价值 24,311,287.31 美元的碳信用额度。最终，通过建立创新的发电厂系统，拟议的太阳能 ORC 系统在推进能源治理方面大有可为。
