Why are mobile energy storage systems important in Europe?

The emphasis on technology advancement in North America guarantees the region’s sustained control of MESS solution efficiency and scalability. Mobile energy storage systems are immensely used in Europe due to its focus on sustainability and energy security.

Is V2G a good investment for electric vehicles?

V2G shows promising cost competitiveness and profitability currently. The rapid expansion of electric vehicle market brings a huge stock of batteries, which can potentially serve as distributed energy storage systems to provide grid services through Vehicle-to-Grid (V2G) technology.

How does Charger power capacity affect V2G cost & profitability?

The impact of charger power capacity on the cost and profitability of V2G is multifaceted. The positive side is that higher power capacity allows for faster charge and discharge rates. Such a benefit, however, comes with higher infrastructure-related costs.

Is V2G a cost-effective energy storage system?

Results show that V2G is more cost-effective than most stationary energy storage technologies and is comparable to lithium-ion battery systems, which have an LCOS of $0.290/kWh for frequency regulation. In the PS strategy, the LCOS is $0.132/kWh.

Does battery cost affect V2G profitability?

The impact of battery cost on V2G profitability is rather intuitive, as it essentially determines the battery replacement cost. To quantify this effect, we evaluated the cost and profitability of V2G across a battery cost range of $60–120/kWh. Specifically, the lower bound cost covers only essential material costs .

How does SoC affect EV power supply?

In addition to the grid's power demand, the SOC of the battery also serves as a critical factor in determining the battery's power output for frequency regulation services. When the battery's SOC reaches its upper or lower thresholds, the EV can no longer provide down-regulation or up-regulation services.
