    摘要: A method for optimizing the efficiency of a solar powered hydrogen generation system is disclosed. The system utilizes photovoltaic modules and a proton exchange membrane electrolyzer to split water into hydrogen and oxygen with an efficiency greater than 12%. This high efficiency for the solar powered electrolysis of water was obtained by matching the voltage generated by photovoltaic modules to the operating voltage of the electrolyzer. Optimizing PV-electrolysis systems makes solar generated hydrogen less expensive and more practical for use as an environmentally clean and renewable fuel.

    摘要: One embodiment of the invention includes a photovoltaic system that provides both electricity and low-grade heat, together with many options of utilizing the energy. The electricity may efficiently be used to drive a high-pressure electrolyzer that produces hydrogen. The hydrogen pressure may be boosted to a final compression of at least 700 bar. In one embodiment the pressure may be boosted using a metal-hydride compressor and stored. The stored high pressure hydrogen may be used to fill fuel-cell electric vehicle (FCEV) tanks. The electricity can also be used to efficiently charge the batteries in an extended range electric vehicle (EREV).

    摘要: In a preferred method, a spilled fluid, lighter than and immiscible with water, is removed from the subsurface by first penetrating through the fluid zone and at least partially through the groundwater zone to provide a bore in communication therewith. Then, at suitable intervals, an amount of fluid is extracted from the fluid zone through the bore at a selected rate. In addition, at suitable intervals, an amount of water from the groundwater zone is extracted through the bore at a selected rate. Meanwhile, a vacuum is applied to one or more selected portions of the subsurface to draw air therethrough, to volatilize volatilizable components of the fluid, and to induce movement of the volatile (vapor) and liquid and heavy components of the fluid into the bore for extraction. A recovery well has a perforated first tube in the bore and a second tube which moves axially within the first tube to expose a varying portion of the perforated axial extent of the second tube to the vacuum, whereby the vacuum is applied to a selected portion of the subsurface directing movement of air therethrough to volatilize light components and to induce movement of the vapor and liquid components to and through the tubes and to the top surface.
