Calculating Hydrogen Mass Storage in Compressed Vessels

In summary, the speaker is looking for an equation to calculate the mass storage of Hydrogen in compressed vessels and has found a link that provides the necessary information. They are interested in creating something similar for internal use and are asking for suggestions on how to approach this. They are also familiar with the concept of compressibility factor z and have some knowledge of calculating mass using volume, temperature, and pressure. They are also familiar with other equations of state like van der Waals.

Hello all;

I am looking for an equation for calculating mass storage of Hydrogen in compressed vessels
I have fount the following link (https://nanosun.co.uk/hydrogen-tools) which provides what i need but would like to create something similar for internal use

Can you suggest an approach to this?

Then you know how to calculate the mass, given the volume, temperature, and pressure? Also, are you familiar with other equations of state, like van der Waals?
 

1. How is hydrogen mass storage calculated in compressed vessels?

The mass of hydrogen stored in a compressed vessel can be calculated by multiplying the pressure of the vessel (in atmospheres) by the volume of the vessel (in liters) and then dividing by the molar mass of hydrogen (2 grams/mol). This will give you the mass of hydrogen in grams.

2. What is the molar mass of hydrogen?

The molar mass of hydrogen is approximately 2 grams/mol. This means that one mole of hydrogen atoms weighs 2 grams.

3. What is the ideal pressure for storing hydrogen in compressed vessels?

The ideal pressure for storing hydrogen in compressed vessels is around 700 bar (10,000 psi). This allows for a high storage capacity while still maintaining safety.

4. How does temperature affect the storage of hydrogen in compressed vessels?

As temperature increases, the pressure inside the vessel also increases. This can lead to a decrease in storage capacity and potential safety hazards. It is important to keep the temperature of the vessel stable to ensure optimal storage of hydrogen.

5. What are the safety considerations for storing hydrogen in compressed vessels?

Some safety considerations for storing hydrogen in compressed vessels include the potential for explosion if the vessel is damaged or exposed to high temperatures, the need for regular maintenance and inspection of the vessel, and proper training for handling and storing hydrogen. It is important to follow safety protocols and regulations when storing hydrogen in compressed vessels.
