Mr. Ivo Pothof (PhD, MSc, 1972) currently manages the Deltares portfolio on Renewable Energy and Energy-efficiency. In this role, he identifies innovations and initiates new strategic projects on geothermal energy, tidal energy and smart control of energy infrastructure.
He is also a member of the Scientific Council of Deltares. Mr. Pothof has a background as an industrial hydrodynamics specialist at Deltares. Joining Delft Hydraulics (currently Deltares) in 1997, he became specialist in fluid transients, optimal control of pipeline systems and air-water pipe flows. His PhD thesis on air-water flows in downward sloping pipes is directly applicable to (waste)water, cooling water and hydropower outlet works.
He has worked on innovative solutions for the water industry in the Netherlands and abroad, like the application of booster pumping stations in the urban drainage system of Amsterdam. He has experience with development of numerical algorithms for fluid transients (WANDA software), commissioning fire fighting systems, field measurements and troubleshooting at chemical plants. He has written guidelines on fluid transients in Dutch standard NEN 3650 – 2006: Requirements for pipeline systems. Mr. Pothof is a member of the Technical Committee of the Pressure Surges Conference Series and affiliated with Delft University of Technology, department of Sanitary Engineering.
He has training experience as a lecturer at Deltares Academy (Hydrodynamics in Pipeline Systems) and as a guest lecturer at Delft University of Technology and UNESCO-IHE. He has published in various peer-reviewed journals and numerous conference proceedings. He graduated in 1995 in Systems and Control Theory at the University of Twente, faculty Applied Mathematics.

Smart Thermal Grid at Delft University of Technology. The heating and cooling infrastructure at the campus of Delft University includes conventional and renewable sources and will include more renewable sources in the future. Optimisation of the entire heating and cooling infrastructure at the campus using WANDA Heat, WANDA Control and other modeling tools. This innovative project will focus on the actual system performance (via monitoring) after modifications and on verification of the design simulations.
