Dr. John Turner has been at NREL since 1979 and is recognized as a world-class scientist and international spokesperson for hydrogen energy and for his contribution in hydrogen production via photoelectrochemical splitting of water and in the development of fuel cells.

He received the U.S. Department of Energy Office of Science Outstanding Mentor Award and has co-authored more than 100 technical publications.

Dr. Turner started his career in electrochemistry at Idaho State University as an undergraduate working on sodium and potassium amalgam batteries. After he received his B.S. degree in Chemistry, he joined Colorado State University (CSU), working on pulsed voltammetric techniques with Bob and Janet Osteryoung's group. He received his Ph.D. in Electroanalytical Chemistry 1977 and then moved onto Caltech to continue postdoctoral work with Fred Anson. At that time, the well-known photoelectrochemist, Heinz Gerischer was visiting Caltech and Dr. Turner began working with him investigating the photoelectrochemistry of layered selenides. It was there that he fell in love with photoelectrochemistry.

Dr. Turner joined NREL, formerly the Solar Energy Research Institute, in 1979 to work with Art Nozik's group on hot-carrier processes at semiconductor electrodes. At this point in his career, he began researching photoelectrochemical water-splitting for hydrogen production, and for seventeen years (1998-2015) held the record for the highest solar-to-hydrogen efficiency from a photoelectrochemical-based device. Dr. Turner's research topics include: semiconductor materials and structures; catalysts for the hydrogen and oxygen reactions; and fundamental processes of charge transfer at semiconductor electrodes.

Dr. Turner received two Midwestern Research Institute President's Awards for Exceptional Performance in Research. Further, he has received the Hydrogen Technical Advisory Panel award for Research Excellence, an Idaho State University Outstanding Achievement Award (2006), the Japanese Society of Coordination Chemistry Lectureship Award, and six Outstanding Mentor Awards from the U.S. Department of Energy for his work with undergraduate students. He is the author or co-author of over 170 peer-reviewed publications in the areas of photoelectrochemistry, fuel cells, batteries, general electrochemistry and analytical chemistry. He is a Fellow of the Renewable and Sustainable Energy Institute, a joint institute between NREL and the University of Colorado, Boulder, and a 2012-2014 Sigma Xi Distinguished Lecturer. He is also co-Editor of the Journal of Renewable and Sustainable Energy, an AIP journal.

Research Interests

Dr. Turner has been recognized as a visionary. His paper "A Realizable Renewable Energy Future" (1999) still receives many citations, and he was highlighted as a visionary in 2004 by Electronic Design Magazine with his article "Hydrogen Could Fuel the Digital Electrical Grid." His vision, which incorporates information, solar, hydrogen, and fuel cell technologies to create an intelligent and advanced electrical grid, could have profound impact on developing nations by eliminating the need to build large, centralized power plants before homes can be powered.
