Mark Kremer

Optimalisation Consultant

“To develop smart, data-driven solutions with which we can rapidly make our energy-system sustainable – that’s what gives me energy!”

Mark is Optimization Consultant at Recoy and is expert in the field of optimizing flexible assets and production processes. He combines a profound understanding of energy-markets with data-driven optimization techniques to realize maximum valorization of energy flexibility.

Mark studied Technical Business Administration at Groningen University, after which he went to Sweden to study at one of the most sustainable technical universities in Europe. After his two-year Master in Operations Management, he followed a specialist track in Sustainability Transitions, which allowed him to combine his passion for Sustainability on the one hand and the Optimization of  Complex Processes on the other hand. After graduation Mark started to focus on the greatest challenge of our time : the energy transition. His interests lie particularly in the area of the transition of complex (industrial) processes and chains, where smart, data-driven solutions are more and more often a key driver for sustainability.
