LADE Simulator: How V2G Contributes to Climate Protection

The Mainz-based e-mobility startup LADE has developed an interactive visualization tool designed to illustrate the specific contribution that Vehicle-to-Grid (V2G) can make to CO2-free power generation. The V2G simulator is freely available.

“Using electric car batteries as storage can be an extremely important building block in achieving Germany’s climate goals. The technology can be implemented very, very easily and affordably, has an enormous impact, and the storage systems already exist. Due to the impending climate crisis, we really need to hurry with the energy transition and cannot wait until hydrogen becomes efficient. We need to act now, and for that, the batteries of electric cars can play a crucial role,” appeals Dennis Schulmeyer, CEO of LADE.

Real data from the Federal Network Agency

Vehicle-to-Grid refers to the temporary storage of electricity in an electric vehicle's battery, which is then fed back into the energy system when needed, the provider specifies. Based on real data from the Federal Network Agency, the V2G simulator concretely visualizes what this could look like for Germany. For selectable periods, it shows the total electricity consumption in Germany as well as the power generated by wind and solar energy. Various expansion targets for renewable energies and the number of electric cars can be set using regulators. Additionally, two specific scenarios are preset and can be viewed through the tool: The traffic light coalition's goals for 2030 and the Agora Energiewende scenario "Climate Neutral 2045". The tool demonstrates that if the federal government can achieve its goal of 15 million electric cars by 2030 and continues to significantly expand renewables, it is realistic to cover around 95 percent of electricity supply with wind, solar, and electric car batteries in the future.

"Our simulator clearly shows that we can store almost all peaks caused by the further expansion of renewable energies with electric car batteries as early as 2030. This allows electricity to be used at different times,” promotes Schulmeyer.
