Vehicle-to-Metal: Electric vehicles secure sustainable energy supply at Wacken Open Air

July 31, 2019|Munich, Wacken

To make the Wacken Open Air greener, the organizers of the festival focus on green tech innovations. On the occasion of the event's 30th anniversary, the technology company The Mobility House and its innovation partner GP Joule will demonstrate what the sustainable energy supply of the festival can look like in the future. 


For this purpose, the two sector coupling experts have cleverly adapted the Vehicle-to-Grid approach: A fully charged electric vehicle - a Nissan Leaf - works as a power storage and supplies the Wacken camp of the future with energy. The Mobility House supplies the technology to store electricity, that has been generated through photovoltaic systems in the vehicle and retrieve it when needed. This intelligent software connects the energy producer, the consumer and the storage. Using car batteries as a decentralised storage — known as Vehicle-to-Grid (V2G) —is suitable for a wide variety of use cases which The Mobility House has already tested in various projects. Electric vehicles and/or their batteries are being used as mobile temporary energy storage and serve as small, flexible power plants. When there is plenty of (sun) light, they can be intentionally charged with renewable energy. This energy can then be given back to the users or the grid flexibly when the cars are not being driven.

"A cleverly designed energy management system is necessary to make all of this work optimally down to the details. That’s exactly why GP JOULE CONNECT has been working on with The Mobility House as a technology partner since the beginning of 2019. The goal is, for one, to make this a practical test and, for another, to be a guiding star for an emissions-free energy supply for the festivals of the future."

The smart software from The Mobility House links the energy producers, consumers and storage. The showcase demonstrates that a comfortable camping setup with typical household appliances and small electric devices, such as a refrigerator, grill, coffee machine, TV, etc., can be supplied with renewable energy. At W:O:A 2019, all electrical devices in the two tents will be supplied with power in this way. If needed, the Nissan Leaf battery can be given an intermediate charge with renewable energy.

"By now, everybody should have understood the fact that the mobility and energy sectors must become emissions-free. As an old-established metal fan, I think it is awesome that together with the organizers of Wacken Open Air, we even make one of the biggest heavy metal festivals in the world CO2-free."

Thomas Raffeiner,

Founder and CEO, The Mobility House

Interested visitors of W:O:A 2019, who would like to find out more about the innovative Vehicle-to-Grid project can get more information from 10 am to 10 pm at the Wacken camp.
