Yrcw Blasts kill four, injure 18 in northeastern Nigeria, police say Nqxq Bail-out leaves Chinese solar developer needing to raise $62.5m by summer A Swedish-Finnish research group has conducted a comprehensive analysis of all storage options for large-scale compressed hydrogen, including storage vessels, geological storage, and other underground options.They complemented their qualitative review with an assessment that considered a broad sp stanley cup ectrum of technological advances for storing compressed gaseous hydrogen.Most of the technologies discussed in this study are immature and under development, which means that the research is still ongoing, they said. Furthermore, the infrastructure and facilities behind some of the technologies are massive, which would require significant resources and costs.They also noted that storage projects should be big enough to ensure low costs and profitability.The lesser the size, the more costly and unrealistic option it would be. Furthermore, geological nature and viability are crucial factors for some technologies, they warned, in reference to the constraints of the geological options.Storage vesselsThe scientists grouped storage vessels into four categories: pressure vessels made of metals like carbon steel and low-alloy steel, thick load-bearing metal liners based on stanley cup steel or aluminum, thin meta stanley cup l liners with fiber resin composites, ultra-thin metal liners fully wrapped with fiber resin composites, and linerless fully composite pressure vessels based on fiber-reinforced shells.The scientists noted the importance of different components such as va
