Thermochemical water splitting cycles
Two processes to effect splitting of the water molecule by means of an external heat source are competing for adoption, for the long-term production of hydrogen: high-temperature electrolysis, and splitting the water molecule through a succession of chemical reactions: a thermochemical cycle. Both processes form part of a strategy of voluntary reduction of greenhouse-gas emissions, and of alter...
متن کاملTritium labeling of antisense oligonucleotides by exchange with tritiated water.
We describe a simple, efficient, procedure for labeling oligonucleotides to high specific activity (< 1 x 10(8) cpm/mumol) by hydrogen exchange with tritiated water at the C8 positions of purines in the presence of beta-mercaptoethanol, an effective radical scavenger. Approximately 90% of the starting material is recovered as intact, labeled oligonucleotide. The radiolabeled compounds are stabl...
متن کاملLow-temperature, manganese oxide-based, thermochemical water splitting cycle.
Thermochemical cycles that split water into stoichiometric amounts of hydrogen and oxygen below 1,000 °C, and do not involve toxic or corrosive intermediates, are highly desirable because they can convert heat into chemical energy in the form of hydrogen. We report a manganese-based thermochemical cycle with a highest operating temperature of 850 °C that is completely recyclable and does not in...
متن کاملSolar thermochemical splitting of water to generate hydrogen.
Solar photochemical means of splitting water (artificial photosynthesis) to generate hydrogen is emerging as a viable process. The solar thermochemical route also promises to be an attractive means of achieving this objective. In this paper we present different types of thermochemical cycles that one can use for the purpose. These include the low-temperature multistep process as well as the hig...
متن کاملAnalysis of Solar Thermochemical Water-Splitting Cycles for Hydrogen Production
Approach • Review all published papers, reports, patents, etc. in the past 25+ years that relate to thermochemical water-splitting cycles, in general, and solar driven cycles, in particular. • Use FactSageTM program to perform chemical equilibrium calculations. • Employ HYSYS/ASPEN Plus chemical process simulation (CPS) program for developing process flowsheet, process analyses and optimization...
