Hydrogen Gas Storage Tanks

Compressed and liquefied hydrogen.

Hydrogen gas storage tanks.

Hydrogen can be stored physically as either a gas or a liquid. 5 2 2 compressed hydrogen storage. Compressed hydrogen is a storage form whereby hydrogen gas is kept under pressures to increase the storage density. In order to maintain liquid hydrogen at this temperature tanks must be perfectly isolated.

The four types of common high pressure gaseous storage vessels are shown in the table. The hydrogen is stored under high pressure in hydrogen storage tanks designed and adapted to facilitate transport. At 252 87 c and 1 013 bar liquid hydrogen has a density of close to 71 kg m 3. On site hydrogen storage is used at central hydrogen production facilities transport terminals and end use locations.

A major drawback of compressed hydrogen storage for portable applications is the small amount of hydrogen that can be stored in commercial volume tanks presenting low volumetric capacity. Gkanas in portable hydrogen energy systems 2018. Hydrogen can be utilized several ways as an energy carrier such as feeding it in small amounts into the natural gas network converting it to ch 4 and introduce the obtained methane into the natural gas network or the stored hydrogen can be directly converted back into electricity via fuel cells. Storage options today include insulated liquid tanks and gaseous storage tanks.

A hydrogen tank other names cartridge or canister is used for hydrogen storage. Even at high pressures over 70 mpa the compressed hydrogen storage presents low volumetric density lower. 10 000 psi were demonstrated in 2001 the first fuel cell vehicles on the road with type iv tanks are the toyota fchv mercedes benz f cell and the gm hydrogen4. Storage of hydrogen as a liquid requires cryogenic temperatures because the boiling point of hydrogen at one atmosphere pressure is 252 8 c.

Car manufacturers have been developing this solution such as. The first type iv hydrogen tanks for compressed hydrogen at 700 bars 70 mpa. Compressed hydrogen in hydrogen tanks at 350 bar 5 000 psi and 700 bar 10 000 psi is used for hydrogen tank systems in vehicles based on type iv carbon composite technology. Today we work with oems around the world to produce hydrogen tanks for fuel cell and internal combustion engine storage.

Storage of hydrogen as a gas typically requires high pressure tanks 350 700 bar 5 000 10 000 psi tank pressure. The project plans to optimize the distribution mode by centralizing the compression which would reduce the costs of setting up a station with the possibility of changing it according to each request thus facilitating its deployment. Applications include automotive transit buses bulk hauling and stationary storage. At this pressure 5 kg of hydrogen can be stored in a 75 liter tank.

In the 1970s we pioneered one of the first hydrogen fuel tanks a composite tank installed on a dodge pickup truck.
