Bibliometric Analysis of Renewable Energy Strategies for Mitigating the Impact of Severe Droughts on Electrical Systems

Applied Sciences, Год журнала: 2025, Номер 15(4), С. 2060 - 2060

Опубликована: Фев. 16, 2025

The global energy transition is pivotal in mitigating climate change. In Chile, the system that includes hydropower faces challenges from prolonged megadroughts, necessitating diversification toward renewable sources like solar and wind energy. However, research gaps persist understanding how these can optimally address climate-induced vulnerabilities. This study conducts a bibliometric analysis to identify trends on strategies under extreme drought conditions, distinguishing it systematic or narrative reviews. A was conducted using Scopus, incorporating 82 selected documents analyzed via Bibliometrix VOSviewer map co-authorship networks, keywords, publications. Results revealed significant increase (26.83%) (25.61%) within period (2005–2024), with most notable growth occurring last six years. Key findings include predominance of studies optimization, technologies emerging as for enhancing resilience water-scarce regions. These insights underscore strategic role energies addressing vulnerabilities while supporting sustainable transitions. implications this work lie guiding future policy frameworks enhance security environmental sustainability.

Ignore variability, overestimate hydrogen production – Quantifying the effects of electrolyzer efficiency curves on hydrogen production from renewable energy sources

International Journal of Hydrogen Energy, Год журнала: 2024, Номер 72, С. 49 - 59

Опубликована: Май 27, 2024

This study investigates the impact of including (or neglecting) variable efficiency hydrogen electrolyzers as a function operating power in modelling green produced from renewable energy sources. Results show that neglecting electrolyzer efficiency, is commonly done studies hydrogen, leads to significant overestimation production range 5–24%. The effects time resolution used models are also investigated, well option for switch stand-by mode instead powering down and ramp rate constraints. indicate these have minor effect on overall production, with use hour data leading 0.2–2%, relative using 5-min data. three solar farms wind Australia, which it observed 55% more than farms. results this highlight critical importance production. As industry scales, continuing neglect would lead by tens megatonnes.

Case Studies in Thermal Engineering, Год журнала: 2024, Номер 60, С. 104647 - 104647

Опубликована: Июнь 4, 2024

A novel thermal integration approach is introduced for a biomass-driven gas turbine power plant that generates electricity, coolant, and liquefied hydrogen. The designed scheme encompassed an organic flash cycle, bi-evaporator ejector refrigeration unit, high-temperature water electrolyzer hydrogen production, multi-effect desalination cycle supplying electrolysis process, Claude liquefaction. system's importance comes back to using biomass feedstock as the input fuel utilizing liquefaction method. In addition possibility of deploying system in remote areas, it provides opportunity storage smaller volume more accessible transportation. On other hand, comparative method selecting environmentally friendly fluid heat recovery subsystem another crucial aspect present study from environmental aspect. It found R161 appropriate choice among seven studied working fluids. Subsequently, comprehensive evaluation entire thermodynamic aspects performed intelligent process. By considering energy exergy efficiencies along with CO2 emissions objective functions, thorough sensitivity analysis triple-objective optimization are carried out. Hence, artificial neural networks objectives developed integrated into NSGA-II Employing LINMAP decision-making, values attained, exhibiting 39.6% efficiency, 36.1% 631.7 kg/MWh emissions. Considering optimum solution, proposed capable producing cooling, capacities 4526 kW, 1875 21.22 m3/day, respectively. Additionally, scenario yields exergoenvironmental index 0.579 exergetic stability 0.61. generation rate m3/day.
