Kas Hemmes

Dr. Kas Hemmes serves as Associate Professor at Delft University of Technology, where he has made significant contributions to energy systems research and sustainable technology development. His career began with a master's in physics, followed by 15 years as coordinator of the Delft fuel cell research program in the Materials Science Department. Since 2001, he has been with the faculty of Technology Policy and Management, focusing on energy systems, sustainability, and technology dynamics. His research emphasizes multi-source multi-product energy systems and the reduction of thermodynamic losses in energy conversion, noting that 50% to 90% of primary fuel exergy is lost during power conversion. His impact in the field is evidenced through his coordination of multiple European and national research projects in fuel cells, hydrogen, and natural gas, particularly at the intersection of technology and society. With 88 publications in ISI journals and an H-index of 13, his work spans three decades of high-temperature fuel cell research, hydrogen production methods, and sustainable energy transitions. His expertise includes public acceptance of hydrogen technologies and the development of innovative energy conversion systems.
