Meet René

René van Wesenbeeck works as a domain architect at Alfen, where he focuses on the concept development of energy storage systems. He develops and optimises solutions that support grid stability and energy efficiency. René not only has technical expertise but also partners with universities to develop innovative energy solutions. He works with his colleagues to refine these technologies and bring them to market.

How did you get into energy technology and start working at Alfen?
I’ve worked in energy technology for over 19 years. After graduating from Delft University of Technology, I worked as an assistant professor before transitioning into the industry in 1995. My early career focused on high-frequency power electronics such as frequency converters, but I was always drawn to developing practical hardware solutions. About nine years ago, I joined Alfen because the company’s focus on energy storage and charging infrastructure immediately appealed to me. The combination of technical challenges and societal impact made it the right choice for me.

What does your role involve?
As a domain architect, I focus on concept development for energy storage systems. My role involves shaping ideas at the early stages of product development and ensuring they can be scaled for real-world use. Once a concept is defined, I work with our engineering teams to refine and implement it. To keep innovating, I partner with universities to explore emerging technologies and work closely with colleagues at Alfen to align market needs with technical possibilities.

How is your work helping our customers transition to more sustainable energy?
I believe in practical, measurable solutions that directly contribute to the energy transition. One of the biggest challenges with renewable energy is variability. Our storage systems help stabilise the energy supply by storing wind and solar power for use when demand is high. We also develop mobile storage units that replace diesel generators at construction sites and events and help reduce CO2 emissions and noise pollution.

What do you enjoy most about working at Alfen?
Alfen has an open and collaborative culture. Over the years, I’ve seen the company grow into a diverse, international workplace where different perspectives drive innovation and problem-solving. I also appreciate how Alfen combines technical innovation with practical application. It’s not just about developing ideas; it’s about ensuring they work in practice.

What has been the most interesting project you've worked on while at Alfen?
One of my defining projects was Alfen’s first commercial energy storage system in 2016. Initially, storage projects were mainly subsidy-driven and focused on pilot projects, but with a commercial approach, we were able to bring the technology to market. This changed with our first commercial-scale solution, a 1MW system along the A15 highway in the NL, which proved our technology was ready for large-scale use. This project remains operational today. I also helped develop our mobile storage systems, which are now widely used at events, construction sites and temporary energy supply locations. These systems reduce diesel use and provide reliable, sustainable energy in remote areas.

What inspires you in your role?
I find team-based collaboration particularly inspiring. We are increasingly working in cross-functional teams, where technical and commercial specialists collaborate from the start of a project. I also enjoy mentoring younger engineers and encourage them to follow their interests and explore the field with curiosity. Having worked in energy technology for decades, I see it as my responsibility to share knowledge and experience in this rapidly evolving industry.

What do you enjoy doing in your free time?
I like to stay active, so I go cycling every Sunday morning, which helps balance my time at work. I recently bought a new apartment, which has kept me busy. I also enjoy good conversations over a glass of wine and have a strong interest in Latin American culture. I’ve visited the region several times and find the history and engineering achievements of ancient civilisations fascinating, especially the Mayan and Incan cultures.
