Table 2 Comparison of the characteristics of present (fossil fuel dependent) and future (electrified) grid-transportation systems

From: Unveiling sectoral coupling for resilient electrification of the transportation sector

Category

Fossil-fuel supply chain

Electricity supply chain

Energy independence

Depends on global imports and exports of crude oil; shortage of supply impacts the entire economy.

With increased clean energy adoption, the nation will be relieved of its interdependence on the global crude oil market.

Coupling betweensectors

Dependent on electricity for refining, pumping, dispensing, etc.

EVs are completely dependent on the electricity sector, and with clean energy adoption, fossil-fuel needs for power production will be reduced.

Production location

Only well sites and refineries; fossil fuels may be imported.

Spread throughout the nation, and distributed energy resources (DERs) can be local.

Dependence ontransportation

Highly dependent on 190,000 miles of pipelines; 1000s of rail cars, vessels, barges, and 100,000 tanker trucks for fuel distribution; a massive amount of fossil fuel consumed for transporting finished motor gasoline.

Dependence on electricity infrastructure; with a reduction in fossil-fuel-based generation, dependence on pipelines and the transportation sector for the supply chain will be further reduced.

Transmission speed

Days to weeks.

Close to the speed of light.

Energy storage

Massive storage of crude and refined oil exists.

Energy storage is currently sparse and limited.

Strategic reserve

Helps relieve rare situations of acute shortage.

Distributed storage facilities are available; however, strategic storage similar to the SPR does not exist.

On-premises energy replenishment

Some industrial and commercial entities may have on-premises refueling.

Most residential, commercial, and industrial entities may primarily depend on on-premises recharging (continually increasing).

Market dynamics

Fossil fuel cost is market based and “controlled/set” by a multinational oil cartel.

Electricity price is mostly region/location based and often is highly regulated or monitored.

Point-of-sale experience

Fossil refueling experience is standardized, fast, and accessible.

EV charging has a competing set of charger and platform formats.
