Energy distribution technology
Energy distribution technology is the collection of human-made systems that transport energy, including the primary energy material like coal or crude oil or energy currencies for end use like gasoline or electricity. They are essential for the energy sector, as they allow these commodities to be transported globally to drive the economy. When energy is produced in the form of electricity, gasoline, liquefied natural gas, or any other, it requires transportation to where it can be made useful.
There are immense security systems in place in order to monitor and aid the safe functioning of these technologies, which can be read about here.
Energy transportation systems are vastly different depending on what is being transported. These systems require extensive infrastructure: namely the electricity grid, the pipeline grid and a network of rail, road and water shipping.
- Electrical grid - Usually, power plants produce large amounts of electricity. This electric power must be distributed, usually over large areas. The electrical grid is what we call the network of wires that transmits and distributes this electricity. These wires include both large high-voltage and smaller low-voltage power lines, along with numerous substations, the grid efficiently transmits this power to consumers. Usually power loss is minimized. Learn more here.
The technology used by the electrical grid is complex and interconnected, for a sense of this see Figure 2 below.
- Pipelines - crude oil and raw natural gas are extracted from nature and often need to be transported long distances to where they are refined. Once refined, they are transported again to the end users. Pipelines play an important role in this process: both taking the fluids to be refined, and to move the refined products around. In Canada alone there is an estimated 825 000 kilometers of lines that serve to transport natural gas, liquefied natural gas products, crude oil, and other refined petroleum products. The enormous cost of constructing pipelines limits their use to locations where very large volumes of product are to be moved for an extended period of time, and the payback period for them is typically 15-20 years. Figure 3 below has a map of pipelines in North America.
- Trains, trucks, and ships - both primary fuels such as coal, raw natural gas and crude oil and secondary fuels such as liquefied natural gas and gasoline can also be transported by the same infrastructure that ships other goods. Vehicles of all sorts are used, such as freight trains, LNG carriers and oil trucks. Pipelines are often used for the distribution of large quantities of liquids and gases, however when the amount of petroleum products needed to ship cannot justify the cost of building a pipeline, these methods are preferred.
