Virtual Pipeline

Enwave’s “Virtual Pipeline” – supply of natural gas to regional Victoria

As part of the project, Enwave Victorian Networks will provide reticulated natural gas to eleven towns via the use of a Compressed Natural Gas (CNG) “Virtual Pipeline” solution. 

Where distance and demand do not justify an investment in a traditional gas pipeline, Enwave's Virtual Pipeline offers an attractive alternative for gas distribution to end users, large commercial & industrial energy consumers.

Virtual Pipeline System Working Principle

The Virtual Pipeline solution consists of four interdependent systems, a Compression Station where gas is compressed and transport modules are filled, a Transportation system, and Receiving Stations where the transported gas is delivered in volumes based on town consumption demand. In turn, gas is then distributed within each town via a conventional gas distribution network.

Virtual Pipeline System Basic Advantages

Modularity, the system is conceived based on this concept, resulting in the following advantages:

  • Maximization of transported gas. The scalability and custom engineered solutions, maximizes the amount of transported gas and reduces the operating cost per cubic meter of natural gas delivered.
  • Scalability. Working with multiple size storage containers allows the system to grow at the pace of demand. Changes in consumption can be matched with additional stationary and transportable CNG.
  • Transportability. The extensive design and engineering of the transport modules enables safe and efficient transportation to where ever natural gas demand is.
  • Balance between operating and investment costs. Thanks to both its modularity and scalability, this system allows for optimal sizing to strike a perfect balance between operating and investment costs.

Gas Supply

Enwave via its Tas Gas Retail business will supply natural gas from the Victorian gas transmission system for compression and to meet the regions and consumers gas demands.

Infrastructure

The four main components of Enwave's Victorian Regional Energy Virtual Pipeline solution are:

  • Compression Stations (‘Mother Stations’) - Compression and dispensing of CNG into bulk storage. Development of two fully redundant Mother Stations and a capacity upgrade for a third smaller station in Derrimut are to be developed during the project. The locations of the two compression stations will be confirmed shortly.
  • CNG Transport - Prime movers in B-double configuration, towing 1 x 20ft & 1 x 40ft CNG transport modules from Mother Stations to Receiving/Daughter Stations.
  • Receiving Stations (‘Daughter Stations’)- Receives CNG from CNG transport and stores it on-site at each of town. Reduces pressure down for supply, into a conventional gas network system, to the adjacent town.

Town Distribution Networks - From the outlet of each Receiving Station, Brookfield will roll out a conventional Gas Distribution Network within each of the town enabling consumers to access reticulated natural gas.
