Hydrocell’s metal hydride technology is a very safe and simple way to store, transport and use hydrogen.

Hydrogen is not stored in the metal hydride in gaseous form, but is adsorbed into the material’s crystal structure. The energy densities that can be achieved using metal hydride are very large. Another advantage of using metal hydride is the low storage pressure, just 2-4 bar depending on temperature and the amount of hydrogen that the storage unit contains. The metal hydride pressure level can be adjusted to suit different client applications.

As storage units do not suffer from self-discharge, they can be stored for years without any loss of capacity. Since only hydrogen is stored in the metal hydride, the gas drawn from storage units is very pure, approximately 99.9999%.

Hydrocell’s portable hydrogen storage units are well suited to use with fuel cells and other applications that require a source of hydrogen. All Hydrocell storage units are fitted with a self-sealing quick-fit hose connection and a safety valve, and can be easily connected to a fuel cell or other device using a flexible pipe.

Two standard sizes of storage unit are available: the HC-MH200 and the HC-MH1200. The HC-MH200 holds 230 litres of hydrogen, weighs just 2.5 kg and has the dimensions of a soft-drink can. It has a capacity of 40 Ah (12 V DC).

The HC-MH1200 holds 1200 litres of hydrogen, weighs 11 kg and is the size of a small fire extinguisher. It has a capacity of 220 Ah (12 V DC). Both models incorporate an efficient brush-type heat exchanger.
