The 2024 Nelson W. Taylor Lecture in Materials at Penn State University will focus on 'Materials for Energy Innovation,' with keynote speaker Sossina M. Haile discussing protonic electrochemistry for sustainable energy technologies, particularly emphasizing the use of hydrogen. Haile highlights the importance of advances in electrochemical cells for reversible hydrogen generation, which can serve as a means of energy storage and conversion. The talk also proposes using ammonia as a carrier for hydrogen to overcome the limitations of a hydrogen delivery infrastructure in various applications. The lecture series includes talks by Penn State faculty members on sustainable energy and materials science. The event, honoring Nelson W. Taylor's contributions to ceramics research at Penn State, aims to address the challenges and advancements in sustainable energy technology.
