Sweden Harnesses Electric Vehicles to Power Homes and Stabilize the Grid
Sweden is pioneering the use of electric vehicles as mobile energy storage to power homes and stabilize the electricity grid, achieving cost savings and enhancing energy resilience.
Key details
- Amer Kadić uses an EV and solar panels to reduce electricity costs by storing and discharging energy based on price fluctuations.
- Nearly 500,000 EVs in Sweden can function as mobile batteries, available most of the time when parked.
- Energy Bank's co-founder notes EVs could collectively provide power comparable to a nuclear reactor with proper infrastructure.
- The technology supports grid stability, reduces reliance on fossil fuel generators, and is being piloted with major companies like Polestar and Volvo.
In Mariefred, Stockholm County, Amer Kadić leverages vehicle-to-home (V2H) technology by using his electric vehicle (EV) as a mobile battery, significantly reducing his energy costs. Equipped with solar panels and a powerful charging station, Kadić stores excess solar energy in his EV battery when electricity prices are low. After sunset, when prices spike, the vehicle powers his home and can even sell surplus energy back to the grid, saving him thousands annually.
Sweden has nearly half a million EVs that can act as mobile energy storage units, available 96% of the time when parked. Klas Boman, co-founder of Energy Bank, highlights that with the proper chargers and software, these vehicles could collectively provide power comparable to a nuclear reactor. The software optimizes charging and discharging times to maximize savings and grid benefits.
Anna Larsson from the research institute Rise emphasizes that the technology not only reduces electricity bills but also enhances grid stability and resilience during outages, cutting reliance on fossil-fueled diesel generators.
Multiple pilot projects across Sweden, including partnerships with Polestar and Volvo Cars, are currently testing vehicle-to-grid (V2G) and V2H solutions to integrate EVs into energy management systems.
This innovation aligns with Sweden's green energy goals by leveraging EVs for energy storage and contributing to fossil fuel reduction.
