    Biological hydrogen production project is being carried out to develop renewable and environmentally acceptable energy sources. Basic research has been done to obtain capable microorganisms for hydrogen production (photosynthetic bacteria and cyanobacteria) by using genetic engineering methods. For photosynthetic bacteria, control of put promoter has been examined to regulate the expression of the photosynthetic proteins to increase the efficiency. In the case of cyanobacteria, replacement of enzyme for hydrogen production has been examined to introduce hydrogenase gene into cyanobacteria. Adding to the improvements, experiments were done to measure the light penetration precisely and its effect to hydrogen production.

    In order to improve the thermal efficiency of 2-propanol /acetone /hydrogen chemical heat pump system, enhancements of the conversion for 2-propanol dehydrogenation with carbon-supported metal catalysis in liquid-film states were investigated. The amount ratio of solid catalyst to liquid substrate was an important factor, because not only the rates of hydrogen evolution but also the total conversions were influenced sensitively and tremendously under boiling and refluxing conditions. The equilibrium conversion of 12.7% at 90°C was surpassed easily as the consequence of reactive distillation and nonequilibrium nature of liquid-film conditions for catalytic 2-propanol dehydrogenation.

    JAERI has been developing a hydrogen storage type high temperature chemical heat pump, which can amplify thermal energy of the temperautre 373K to 1273K as well as store mass hydrogen energy. To testify the concept of this type of heat pump, we constracted heat pump element test facilities and has been testing its performance.

    The present paper reports the recent tests results of the facilities, including R&D on metal-hydride materials

    PEFC(Polymer Electrolyte Fuel Cell) seems preferable fuel cells for vehicles because of high-current density and low operating temperature. For vehicular power systems, fuel cell and battery hybrid system is applied. Light weight fuel cells are required for commercialization of fuel cell vehicles, and also light weight on-board hydrogen fuel storage systems are to be developed.

    In the New Sunshine Program, systematization projects on an effective compound network system have been carried out for achieving reduction of fossil fuel comsumption and protecting the global environment. Hydrogen technologies are developed as the key technologies, especially as the energy transpotation media in these projects. The concept of the projects will be introduced with expectation of the comments from the hydrogen research experts.

    The National Hydrogen Program of the United States is dedicated to encouraging and supporting the development of safe, practical, and economically competitive hydrogen technologies and systems to meet our energy needs. The future world energy industry will need to use hydrogen from renewable resources to satisfy energy demand and to reduce pollution.

    The U.S. Department of Energy (DOE) manages the National Hydrogen Program. In this role, DOE provides national leadership and acts as a catalyst through partnerships with industry. These partnerships are needed to assist in the transition of sustainable hydrogen systems from govemment-supported research and development to commercial successes in the marketplace.

    The challenges that the program is addressing include infrastructure issues, process efficiency, environmental impacts and advantages, safety issues, reliability, and cost competitiveness. We are addressing these obstacles through core research and development, technology validation, demonstrations, industry interaction, and systems analysis.

    The U.S. Hydrogen Program is poised to overcome the technical and economic challenges that currently limit the impact of hydrogen on our energy picture. With cooperative research, development, and demonstrations, the hydrogen future will become a reality.
