Title: Hydrogen from renewable resources monthly progress report

Abstract

During February, we achieved two significant results in our hydrogen storage activates. Reversible hydrogen uptake and release was measured at room temperature, near ambient pressure on the (IrClH{sub 2}(H{sub 2})Pr{sup i}{sub 3}) complex. Dr. Jensen also observed that certain polyhydzide complexes catalyze the low temperature, reversible dehydrogenation of cycloalkanes to aromatic hydrocarbons at temperatures as low as 130{degrees}C. This discovery may represent a breakthrough in chemical storage of hydrogen as all other cycloalkane dehydrogenation systems require temperatures in excess of 300{degrees}C.

  • This progress report updates two tasks. In the area of hydrogen production, photobiological production and photoelectrochemical production advances are discussed as well as thermochemical production of hydrogen from wet biomass. In the area of hydrogen storage, reversible catalytic dehydrogenation of cycloalkanes by polyhydride complexes and polyhydride systems engineering are presented.

  • This report summarizes activities for September 1995 for the following areas of Hydrogen Production Task: Photobiological production; Photoelectrochemical production; and, Thermochemical production of hydrogen from wet biomass. For the Hydrogen Storage Task, these areas are addressed: Reversible catalytic dehydrogenation of cycloalkanes by polyhydride complexes; and, Polyhydride systems engineering.

  • This monthly reports describes progress in three projects, namely (1) Thermochemical Production of Hydrogen from Wet Biomass, (2) Photoelectrochemical Production, and (3) Photobiological Production.

  • This month, further progress in the design and fabrication of the new reactor/feeder was achieved. High-pressure gas separation was explored further, and some supplemental experiments on activated carbon production and carbon gasification characteristics in supercritical water were carried out.

  • This monthly report of project entitled Hydrogen from Renewable Resources describes progress in five tasks, namely (1) Thermochemical Production of Hydrogen from Wet Biomass, (2) Photoelectrochemical Hydrogen Production, (3) Photobiological Production and (4) Hydrogen Storage (via reversible catalytic degradation of cycloalkanes by polyhydride complexes), and (5) Thermodynamic Characterization and Engineering.
