Shush Money: How Hydronauten's Silent Pumps Save Millions in Energy Costs – We talk IoT #68

In this episode, we conclude our special series on the Advanced Electronics Challenge with the winners themselves: Johannes Büker, CEO, and Paul Werner, CTO of Hydronauten GmbH. Their innovative solution addresses a significant hidden energy drain – pumps consume approximately 30% of the EU's electricity.

Hydronauten addresses two critical challenges simultaneously: reducing harmful vibrations that damage infrastructure and residents' quality of life while dramatically improving energy efficiency. Their "quiet hydro technology" applies noise-cancelling principles to pump systems, enabling 20-30% energy savings and opening new possibilities for grid stabilisation.

Johannes and Paul explain how their technology transforms existing pump installations into smart, efficient systems that can help stabilise renewable energy grids. The conversation reveals how pump-based grid stabilisation could have prevented recent power outages in Spain and Portugal and why this overlooked technology represents a crucial piece of the renewable energy puzzle.
