Abstract
A method for storing very high purity hydrogen in a salt cavern is provided. The method includes introducing a compressed very high purity hydrogen gas into a salt cavern, thereby producing a stored very high purity hydrogen gas; maintaining the stored very high purity hydrogen gas at a pressure greater than about 1.0 psi per linear foot of height within the cavern, and less than about 4.0 psi per linear foot of height within the cavern.
Claims10
A method for storing very high purity hydrogen in a salt cavern, comprising a salt cavern wall, the method comprising:
- introducing a compressed very high purity hydrogen gas into the salt cavern, thereby producing a stored very high purity hydrogen gas;
- and
- maintaining the stored very high purity hydrogen gas at a pressure greater than about 1.0 psi per linear foot of height within the cavern, and less than about 4.0 psi per linear foot of height within the cavern.
A method for storing very high purity hydrogen in a salt cavern, comprising:
- introducing a compressed very high purity hydrogen gas into the salt cavern, thereby producing a stored very high purity hydrogen gas;
- and
- maintaining the stored very high purity hydrogen gas at a pressure greater than 1.0 psi per linear foot of height within the cavern, and a pressure less than 4.0 psi per linear foot of height within the cavern,
- whereby the salt cavern forms a substantially impermeable barrier to the stored very high purity hydrogen therein between pressure greater than 1.0 psi per linear foot of height in the cavern and a pressure less than 4.0 psi per linear foot of height in the cavern.
