With its roots in the „Transport Economic Energy Strategy“ (VES), the Clean Energy Partnership has set the goal to provide comprehensive evidence that it is possible for normal customers to safely use hydrogen for road transportation. Even the limited renewable energy sources available to us at the moment can be used to produce hydrogen.
