Electric cars with V2G technology can send power to the grid and money into the owner's pocket. The report shows potential, but FDM disagrees with the size of the amount.
New V2G technology allows electric cars to send power back to the grid. This could mean significant savings for car owners. A report from Eurelectric and EY mentions a potential of up to 6,800 kroner annually. V2G can also support the balance of the electricity grid.
The technology is called vehicle-to-grid, or V2G for short. It allows the electric car's battery to act as a storage device. The electricity can be sent back to the grid when needed.
According to the report , which Eurelectric and EY are behind, there is great potential in the technology. Electric cars will be able to cover four percent of Europe's total electricity consumption by 2030. This is equivalent to the power consumption of around 30 million homes.
In our neighboring country Sweden, for example, V2G electric cars are expected to be able to deliver six terawatt hours of electricity.
In addition to lower costs for consumers, the technology could help the electricity grid. It could also accelerate the transition to renewable energy, according to the report.
The economic benefits of V2G technology
The report points to major savings for Europe's grid operators. This could be up to 30 billion kroner annually. The savings come from a more stable and optimized electricity grid.
For electric car owners, the technology can also mean lower expenses. Total cost of ownership can be reduced by up to twenty percent.
An average electric car owner might save 2,000 kroner annually compared to fossil-fuel cars. That's without taking V2G technology into account.
With V2G, the annual savings can potentially reach 6,800 kroner. However, the amount depends on the car's battery and driving pattern.
However, the member organization FDM questions the size of the amount. According to TV2, their figures point to an annual gain of around 4,000 kroner. This is significantly lower than the report's figures.
Disagreement about how much the electric car can save drivers
The disagreement about the potential is also seen in the expectations for the number of electric cars. The Danish government expects around 900,000 electric cars on the roads by 2030.
The car importers' organization, Mobility Denmark, expects a much higher figure. They estimate 1.6 million Danish electric cars in 2030.
There is therefore a large difference in the forecasts for the future. This affects the assessment of the overall effect of V2G technology.
V2G technology is fundamentally about utilizing the battery capacity of electric cars. The cars can help stabilize the electricity grid.
This could potentially provide economic benefits to the owners. The potential depends on the spread of the technology and electricity prices.
The technology is still new, but the potential of V2G is interesting for electric car drivers. Developments in electric cars and charging technology are progressing rapidly.
