How to calculate hydrogen energy storage capacity

How to calculate storage capacity of hydrogen in a geological formation?

This applet helps you calculate the storage capacity of hydrogen in million metric tons (MMT) in a geological formation under subsurface PT conditions. The basic formula used is: Where density is calculated based on real gas formular PV = nZRT. Limits: temperature between 0 and 200 C, and pressure between 0.1 and 200 MPa.

How much energy does it take to store hydrogen?

Approximately 5-8% of the energy content related to the lower heating value (LHV) is used for storing hydrogen in metal hydride form. About 10% is required for storage at 200 bar, and 15.5% for storage at 800 bar.

How do you calculate the gravimetric storage capacity of a hydrogen absorbing material?

The gravimetric storage capacity of a hydrogen-absorbing material, in which the hydrogen is stored within the bulk of the material, is typically calculated from the ratio of the mass of hydrogen stored within the metal or compound to the mass of the host material including the hydrogen , so that the capacity in wt.%, C wt.%, is given by,

What is hydrogen content?

The most frequently quoted hydrogen content quantity, in terms of storage applications, is wt.%: the weight percent capacity or the gravimetric storage density of a material.

Why do you need a hydrogen calculator?

At Stargate Hydrogen we think of every detail to help your industry to reduce carbon emissions by adopting green hydrogen. That is why we created the Hydrogen calculators. Here you can calculate the mass of hydrogen, convert between hydrogen mass and volume, or convert between hydrogen mass and the energy content.

What is the production ratio of hydrogen fuel cell?

Production ratio : kWhe/kgH2 Value between 51 et 67 kWhe/kGH2, default value 56 kWhe/kGH2. Production ratio of hydrogen fuel cell : kWhe/kgH2, Default value 16 kWhe/kgH2. Performance ratio of the DC/DC converter : Default value 0.98, or 2% of losses. Performance ratio of the DC/AC converter : Default value 0.95, or 5% of losses.
