DESCRIPTION:Sophia Haussener\nLaboratory of Renewable Energy Science and E
 ngineering\nEPFL Lausanne\nChE-605 - Highlights in Energy Research seminar
  series\nSolar radiation is the most abundant energy source available but 
 it is distributed and intermittent\, thereby necessitating its storage via
  conversion to a fuel (e.g. hydrogen or carbohydrates) for practical use. 
 Solar thermo-chemical and photo-electro-chemical approaches (and combinati
 ons thereof) provide viable routes for the direct synthesis of solar fuels
 . Both approaches involve complex interactions between multi-mode heat tra
 nsfer\, multiphase flow\, charge transfer\, and chemical reaction.\nFirst\
 , I focus on cost competitive photo-electrochemical (PEC) devices. I revie
 w the development of our PEC model framework1. I then show how we used thi
 s model to design and implement a PEC device with a solar-to-fuel efficien
 cy of 17%. Finally\, I discuss ongoing scaling approaches by our lab for t
 he design\, implementation\, and testing of these devices\, in order to br
 idge the gap between research and practical application.\nSecond\, I discu
 ss our work on high-temperature electrolysis for the production of fuels. 
 I review the techno-economic modeling\, as well as receiver-reactor modeli
 ng2 followed by experimental demonstration of the approach and an outlook 
 on a more integrated solar-driven thermo-electrochemical hydrogen generati
 on.\nI finish by comparing the various solar fuel generation pathways and 
 compare the challenges and future pathways of the different\, complementin
 g processing routes.\n \nReferences:\n1. S. Y. Tembhurne and S. Haussener
