Delivery period for low-pressure mobile energy storage containers used in subway stations

What is a containerized mobile substation?

Containerized mobile substations are sheltered and address applications in challenging environmental conditions including areas of high pollution, and humidity. Customers requiring shorter overall delivery times and minimal on-site work have been the main drivers for Hitachi Energy's development of pre-fabricated indoor substations.

What underground storage technologies can be used in large-scale hydrogen storage?

In this section, two other interesting underground storage technologies that can be utilized in large-scale hydrogen storage are discussed; the Underground storage of a blend of natural gas and hydrogen, and the Underground methanation reactor.

What is a gaseous fueling station?

Gaseous fueling stations consist of storage containers that are supplied by hydrogen produced on-site, delivered via tube trailers, and/or received from pipelines. This low-pressure gaseous hydrogen is compressed and stored at pressures above the maximum vehicle pressure (either 350 or 700 barg).

What are the types of storage vessels for high-pressure hydrogen gas?

Zheng et al. classified storage vessels for high-pressure hydrogen gas into three types: stationary, vehicular, and bulk transportation . This study focuses on large-scale hydrogen storage; hence, this study discusses in detail only stationary tanks.
