SUMMARY:Biofuels: Challenges and Solutions - Professor Shi-Zhong Li\, Inst
 itute of Nuclear and New Energy\, Tsinghua University

DESCRIPTION:First generation biofuels are in recent downturn\, and second 
 generation biofuels will be competitive in 3-5 years or more. We should de
 velop transitional technologies to end the stalemate of biofuels and speed
  up the commercialization of cellulosic ethanol. Sweet sorghum is a promis
 ing feedstock of ethanol\, and Advanced Solid State Fermentation (ASSF) te
 chnology derived from Tsinghua University can ensure sweet sorghum ethanol
  cost competitive with sugar cane ethanol\, the fermentation time is only 
 24 hours with ethanol yield of 92%\, mathematical models to describe solid
  state fermentation process have been developed to design fermentors for i
 ndustry use. ASSF is a bridge technology from first to second generation b
 iofuels\, will achieve the sustainable development. Research progress in c
 ellulosic ethanol at Tsinghua University\, such as microorganism community
  for producing different enzymes to breakdown cellulose\, and consolidated
  bioprocessing with online separation of ethanol by membrane bioreactor wi
 ll be introduced. The collaboration between Cambridge and Tsinghua on swee
 t sorghum ethanol and celluloisc ethanol is also proposed.   \n\nAbout the
  Speaker\n\nProfessor SZ Li specialises in developing bio-fuels from sorgh
 um and has an experimental station in Inner Mongolia. He has close insight
 s into Chinese energy policy and is called on periodically as an adviser t
 o key ministers. Professor Li is enthusiastic about bilateral cooperation 
 with the UK and has previously done work with Imperial College London. \n
