DESCRIPTION:Prof. Bernard Dam\nMaterials for Conversion and Storage\,\nFac
 ulty of Applied Science\,\nDelft University of Technology\, Netherlands\nC
 hE-602 - Recent Events in Energy seminar series\n\nHydrogen is a vital ele
 ment in the energy transition. While sustainable energy sources such as so
 lar and wind plants will power the planet\, this energy needs to be conver
 ted in chemical bonds to provide storage\, fuel and resources to our futur
 e energy system. Hydrogen is the most simple chemical bond that can be mad
 e by electrochemistry. Given the materials involved in electrolysis and th
 e intermittent nature of its use when powered by sustainable sources\, the
  production cost of electrochemically produced hydrogen is far from compet
 itive. In this talk I will discuss some of our efforts to produce hydrogen
  with various levels of integration with on the one hand solar PV sources 
 and on the other hand battery storage. The integration of different functi
 onalities is challenging but may lead to substantial cost reduction.\n\nAp
 art from producing hydrogen\, we also need ways to purify and detect it. H
 ere\, we make use of the optical changes in metals on hydrogenation. This 
 allows us to develop optical fiber based hydrogen sensors. When using Hf a
 s a detector\, we obtain an extremely large sensing range covering 6 order
 s in hydrogen pressure. Finally\, also the purification of hydrogen using 
 metal hydride membranes still provides a challenge to our understanding of
  hydrogen transport. Using optical methods again\, we find that the existe
 nce of heterogeneous fcc/hcp phase boundaries contributes to a large exten
 t to the fast permeation observed in PdCu-based membranes.
