Peter Vogel

Peter Vogel and his brother Marco run a family business that was founded in 1923 as a forge in the Palatinate village of Harthausen. The enterprise group is active in the sectors automotive, real estate and energy and employs over 200 people at several locations. When Peter was studying business administration in Germany and the USA, he dealt with bio-cybernetic control cycles in companies and their surrounding sectors. In numerous projects, Peter Vogel plans and implements topics such as the sector coupling between the areas of mobility, energy / heat and buildings, e.g. in the Smart City Harthausen. This gave him the rise to the idea of ​​a blockchain-based operating system to enable energy-autonomous quarters by means of digitization. Peter Vogel is a founding member of Ecoliance Rheinland-Pfalz e.V. and brings in many years of know-how in sales, finance and corporate management to OLI Systems.
