V2G Project: Hyundai Group and Vattenfall Test EVs as Mobile Energy Storage

Why It Matters

The pilot demonstrates how electric‑vehicle batteries can serve as distributed grid assets, offering utilities a cost‑effective tool for balancing supply and demand while creating a new revenue stream for EV owners.

Key Takeaways

• 80 Dutch homes will test V2G using EV9 or Ioniq 5
• Vattenfall reimburses up to €500 ($545) for home‑charged electricity
• Cars will discharge between 4 pm‑9 pm to balance peak demand
• Bidirectional charging stations installed free for six‑month trial
• Hyundai/Kia aim to expand V2X services across Europe, US

Pulse Analysis

Vehicle‑to‑Grid technology is moving from concept to commercial reality, and the Hyundai‑Kia/Vattenfall pilot in the Netherlands is a prime example. By equipping 80 households with bidirectional chargers, the project turns each EV’s 50‑60 kWh battery into a flexible storage unit that can feed electricity back into the grid during the 4 pm‑9 pm peak window. Participants receive a complimentary charger and a reimbursement of up to €500, roughly $545, for the energy they draw at home, making the experiment financially attractive while preserving daily driving routines.

From the utility perspective, V2G offers a low‑cost alternative to traditional peaker plants and large stationary batteries. Vattenfall’s automated control platform will orchestrate charging and discharging based on real‑time grid conditions, smoothing out supply‑demand mismatches and reducing reliance on fossil‑fuel‑based backup. The data gathered will inform algorithms that optimize battery usage without compromising driver preferences, such as departure times and minimum state‑of‑charge thresholds. This granular insight is critical as Europe seeks to integrate higher shares of intermittent renewable power.

The Dutch trial is part of a growing ecosystem of bidirectional‑charging initiatives, including Utrecht Energized and Eindhoven’s car‑sharing pilots, and aligns with Hyundai Motor Group’s global V2X roadmap. By extending V2G capabilities to the United States and South Korea, the automaker aims to create a seamless, cross‑border network of mobile storage assets. Successful outcomes could accelerate regulatory support, spur investment in smart‑grid infrastructure, and unlock new business models where EV owners are compensated for grid services, reshaping the economics of electric mobility.
