Integration of the vehicle-to-grid technology

With the increasing pollution level and environmental threats, the 21^st century is moving towards green and sustainable like plug-in hybrid electric vehicles. They have vast scope and capabilities of energy storage. This feature of vehicles is making them to utilize for energy storage and distribute/sell it during `peak´ demand. The vehicle to grid (V2G) technology with some improvement may present a promising solution for future energy problems. The features, applications and advantages of V2G are presented here, along with the challenges to implement it. Many programs by automotive industries, power generation units and government of different countries are being performed to make V2G technology viable for future use.
