Abstract: A method and system for supplying additional hydrogen from a reservoir of stored hydrogen in a salt cavern to a hydrogen pipeline to assist in meeting customer demand for hydrogen is provided. Contaminants introduced while the stored hydrogen stream is in the salt cavern may cause the crude hydrogen stream to not have the required product purity specification. The stored hydrogen is removed from the salt cavern as a crude hydrogen stream and thereafter diluted with higher purity hydrogen formed from the pipeline to form a hydrogen product stream at or below the product purity specification. The hydrogen product can be formed without removal of any of the contaminants in the crude stream, thereby creating a more cost effective and simplified supply process compared to conventional processes employing a salt cavern for hydrogen supply.

Abstract: A method for determining elementary circuits and initial values of flows in a pipe network including one or more source nodes and a plurality of demanding nodes. An upstream node and a downstream node of each pipe is determined. The upstream node has less total resistance than the downstream node to the source node. A pipe joined between an upstream node and a downstream node is selected as an upstream pipe of the downstream node. A pipe which is never designated as an upstream pipe is selected as a circuit origin pipe. A node level, which indicates the number of nodes included in the passage from the source node, is determined. An elementary circuit is determined, by tracing upstream nodes along a first route starting from a first node of the circuit origin pipe and along a second route starting from a second node of the circuit origin pipe in accordance with the node level of the upstream node of each pipe, until the first and second routes reach a same source node or a same demanding node.
