Spiiri, Zaptec & Polestar
V2G in Practice – a demonstration of AC-V2G using passenger cars and AC charging.
In this session, Zaptec, Spirii, and Polestar will address the challenges involved in delivering V2G in a practical demonstration, as well as the issues related to obtaining approval in real-world scenarios. The demonstration closely follows the recommendations from Task 53 and the explanations provided by Energinet in the previous presentations.
The goal is to demonstrate the potential of using a passenger car at a fixed location and to clarify the challenges that may arise when attempting to do the same with multiple, arbitrary vehicles at changing locations and across different service providers.

Steffen Nederby Høj is responsible for Polestar’s strategy and business development, as well as product and network operations in Denmark. As employee number two at Polestar Denmark, Steffen has been one of the key drivers behind the successful launch of the Swedish performance brand in the country.
In addition to holding a Master’s degree (Cand. Merc.) in International Business from Copenhagen Business School, Steffen has over 20 years of international experience from key positions at various automotive manufacturers within the EU. He has a strong technical interest and has spent the past 10 years primarily working with strategy related to electric vehicles, technology, and sustainability. During this period, he spent several years on the board of Dansk e-Mobilitet and helped realize the world’s first vehicle-to-grid research projects and real-life cases involving series-produced electric cars.
Driven by his strong interest in research, Steffen also served as a supervisor for two Master’s theses on V2G at the Technical University of Denmark (DTU) during 2023–2024.
Steffen has extensive experience participating in public debates and panel discussions in relevant contexts, such as Folkemødet. As a fun fact, Steffen is the first Dane to obtain a racing license in an electric car. This took place in the spring of 2023 as a combination of professional development and a demonstration of how far electric vehicles have come since their early beginnings more than a decade ago.
