Transmission, Distribution & Storage

With the issue of energy shortages becoming increasingly serious the need to shift to sustainable and clean energy sources has become urgent. However due to the intermittent nature of most renewable energy sources developing underground hydrogen storage (UHS) systems as backup energy solutions offers a promising solution. The thick and regionally extensive salt deposits in Unit B of Southern Ontario Canada have demonstrated significant potential f Read More

The aim of this study is to review and identify H2 storage suitability in geological reservoirs of the Republic of Lithuania. Notably Lithuania can store clean H2 effectively and competitively because of its wealth of resources and well-established infrastructure. The storage viability in Lithuanian geological contexts is highlighted in this study. In addition when it comes to injectivity and storage capacity salt caverns and saline aquifers present less of a challenge th Read More

A composite hydrogen storage vessel (CHSV) is one key component of the hydrogen fuel cell vehicle which always suffers random vibration during transportation resulting in fatigue failure and a reduction in service life. In this paper firstly the free and constrained modes of CHSV are experimentally studied and numerically simulated. Subsequently the random vibration simulation of CHSV is carried out to predict the stress distribution while Stei Read More

Low-carbon hydrogen is a promising option for energy security and decarbonization. Cooperation is needed to ensure the widespread use of low-carbon energy. Cooperation among hydrogen supply chain (HSC) agents is essential to overcome the high costs the lack of infrastructure that needs heavy financial support and the environmental failure risk. But how can cooperation be operationalized and its potential benefits be measured to evaluate the im Read More

Underground Hydrogen Storage (UHS) as an emerging large-scale energy storage technology has shown great promise to ensure energy security with minimized carbon emission. A set of comprehensive UHS site evaluation criteria based on important factors that affect UHS performances is needed for its potential commercialization. This study focuses on the UHS site evaluation of gas mixing. The economic implications of gas mixing between injecte Read More

In response to the surging global demand for clean energy solutions and sustainability hydrogen is increasingly recognized as a key player in the transition towards a low-carbon future necessitating efficient storage and transportation methods. The utilization of natural geological formations for underground storage solutions is gaining prominence ensuring continuous energy supply and enhancing safety measures. However this approach presents chall Read More

As the global economy moves toward net-zero carbon emissions large-scale energy storage becomes essential to tackle the seasonal nature of renewable sources. Underground hydrogen storage (UHS) offers a feasible solution by allowing surplus renewable energy to be transformed into hydrogen and stored in deep geological formations such as aquifers salt caverns or depleted reservoirs making it available for use on demand. This study thoroughly eval Read More

This paper provides a systematic visualization of the development current status and challenges of salt cavern hydrogen storage technology based on the relevant literature from the past five years in the Web of Science Core Collection database. Using VOSviewer (version 1.6.20) and CiteSpace software (advanced version 6.3.R3) this study analyzes the field from a knowledge mapping perspective. The findings reveal that global research hotspots a Read More

This work included preparing and characterizing new platinum complexes with the ligand 345 -trimethoxybenzoic acid (TMB). The reactions were carried out using a n autoclave in microwave within 3 minutes only in an alkali medium of triethylamine where two moles of TMB reacted with one mole of platinum ion and two moles of PPh 3 or with one mole of diphosphines (Bis(diphenylphosphino)x; x=methane (dppm) ethane (dppe) propane (dppp) ferrocene ( Read More

Wind power-to-gas concepts have a high potential to sustainably cover the increasing demand for hydrogen as an energy carrier and raw material as it has been shown in the past that there is an enormous potential in energy overproduction which currently remains unused due to the shutdown of wind turbines. Thus there is barely experience in maritime production offshore storage and transport of large quantities of liquid hydrogen (LH2) due to the devel Read More
