A system uses existing pipelines, e.g., natural gas, oil, etc., to transport hydrogen to one or more distribution points. The disclosed hydrogen distribution system enables use of water, sewer, storm drain and other existing pipelines for local distribution. Hydrogen is produced from an energy source at a producing location. A safety pipe is located inside an existing pipeline configured to carry a first product and a hydrogen delivery line, configured to carry hydrogen, is placed inside the safety pipe such that a channel is formed between an exterior of the hydrogen delivery line and an interior of the safety pipe. Hydrogen is injected into the hydrogen delivery line and a sweeper gas is injected into the channel to purge any hydrogen that might be leaking from the hydrogen delivery line.

A storage system for storing solid hydrogen includes: a plurality of storages including two or more types of solid hydrogen storage materials having different magnetic intensities; a storage container configured to accommodate the storages; and a coil disposed inside the storage container and configured to apply a variable magnetic field to the storages accommodated in the storage container.
