Abstract
In the transportation of hydrogen using pipelines, existing oil and natural gas pipelines can be retrofitted with inner tubes defining an inter-space between the outer surface of the inner tubes and the pipelines, and providing a fluid at in the inter-space at a higher pressure than that of the hydrogen in carried in inner tube.
Claims21
A pipeline for small atomic structure gases such as hydrogen or helium, comprising
- a double-walled pipeline with an inner wall and an outer wall, wherein the outer wall is defined by an existing oil or natural gas pipeline, and the inner wall is defined by an inner tube that fits into the existing pipeline and is spaced by means of spacers from an inner surface of the pipeline to define an inter-space between the pipeline and the inner tube, and wherein the inner tube is made of a material that won't react physico-chemically with hydrogen or with a fluid that is fed into the inter-space.
A method of transporting hydrogen via a pipeline that includes an outer pipe and an inner tube defining an inter-space between them, comprising:
- transporting the hydrogen within the inner tube, and providing a fluid in the inter-space that is at a higher pressure than the hydrogen in the inner tube.
A method for transporting hydrogen using an existing oil or natural gas pipeline, comprising:
- retrofitting the pipeline with an inner tube that is spaced from the inner surface of the pipeline to define an inter-space between the inner tube and the pipeline, and is adapted to withstand a predefined differential pressure between the inner tube and the inter-space.
A pump comprising an inner housing with means for connecting the inner housing to an inner tube of a pipeline so as to be in flow communication with the inner tube, wherein the pipeline comprises an outer pipe and an inner tube spaced from the outer pipe to define a pipe inter-space between the outer pipe and the inner tube, the pump further comprising an outer housing that defines a pump inter-space between the inner housing and the outer housing, wherein the outer housing includes means for connecting the outer housing to the outer pipe to place the pump inter-space in flow communication with the pipe inter-space.
