Charles Michael Ray interviews Dr. John Turner. Turner a research fellow at the National Renewable Energy Laboratory. His research is primarily concerned with enabling technologies for the implementation of hydrogen systems into a sustainable energy infrastructure. This includes direct conversion systems (photoelectrolysis) for hydrogen production from sunlight and water, materials for advanced fuel cell membranes, and corrosion protection for fuel cell metal bipolar plates. He is the author or co-author of over 140 peer-reviewed publications in the areas of photoelectrochemistry, fuel cells, batteries, general electrochemistry, and analytical chemistry. He spoke at Black Hills State University in Spearfish earlier this month.
