Offshore wind power construction has seen significant development due to the high density of offshore energy and minimal terrain restrictions for farms. However, integrating this into grid remains a challenge. The scientific community is increasingly focusing on hydrogen as means enhance integration these fluctuating renewable sources. This paper reviews research generation, water electrolysis production, large-scale storage. By latest advancements, we propose system that couples seawater (SWE) salt cavern coupling aims address practical issues such Regarding application potential system, details advantages developing in Jiangsu using system. While there are still some challenges it undeniably offers new pathway coastal cities advance sets direction progress.

The aim of this study is to review and identify H2 storage suitability in geological reservoirs the Republic Lithuania. Notably, Lithuania can store clean effectively competitively because its wealth resources well-established infrastructure. viability Lithuanian contexts highlighted study. In addition, when it comes injectivity capacity, salt caverns saline aquifers present less a challenge than other kinds medium. possesses sizable subterranean (Cambrian rocks) that be utilized H2. For preliminary assessment, cyclic injection, production simulation performed. A 10-year hydrogen injection recovery Syderiai aquifer demonstrated feasibility UHS, though efficiency was reduced by nearly 50% using single well for both production. suggests separate wells improve efficiency. However, guarantee economic containment security, detailed assessment structures required specifically at pore scale level. volumetric approach estimated combined capacity approximately 898.5 Gg (~11 TWh) Vaskai aquifers, significantly exceeding previous estimates. findings underscore importance data further research on hydrogen-specific factors optimize UHS Addressing technical, geological, environmental challenges through multidisciplinary essential advancing implementation supporting Lithuania’s transition sustainable energy system. makes possible maximize use energy, reduce greenhouse gas emissions, build more resilient Hence, intensive advancements are needed broader applications

With the increasing penetration of photovoltaic (PV) in power grid, to cope with deteriorating frequency security system, PV stations are required participate regulation by grid codes. Knowing active support capability (AFSC) is essential for strategy design response. Therefore, a comprehensive indicator system and an integrated evaluation method proposed evaluate AFSC stations. By considering several national standards, established from three aspects: stability, support, regulation. In order avoid impact subjective factors, this paper proposes bi-level model combining decision-making trial laboratory (DEMATEL), technique preference similarity ideal solution (TOPSIS), antagonistic interpretive structural modeling (AISM) weighting indicators. Finally, case study was performed based on IEEE 39-bus test station. The results show that can reflect effectively. also developed into software promote its application implementation.

With the development of salt cavern gas storage construction technology, large-scale caverns using sediment voids is expected to solve problem low effective volume formation rate and poor economy high-impurity mines. There are few studies on long-term operation mechanical behavior under influence accumulation currently. This paper height, particle gradation, operating pressure stability by constructing a coupling model discontinuous medium surrounding rock continuous medium. The continuous-discontinuous algorithm suitable for analyzing height gradation creep shrinkage caverns. increase slows down bottom cavern, strengthens restraining effect moves position maximum displacement upper part cavern; has little rate, greater coarse content, smaller rate; pressure, more conducive maintaining slowing upward movement body increasing space in cavern. research results can provide reference evaluating sediment-type storage.
