A Solar-Driven System for Industrial Dehumidification and Steam Generation

Maxwell J., D’Antonio M., Henkel E.T., Rigos V., May K., Creamer K., ERS, US

This paper introduces a solar thermal system that can be used for industrial applications to generate low pressure steam, to drive an absorption chiller, or both. Steinway & Sons is installing thirty-eight tracking parabolic trough [...]

Enriched methane production by solar steam reformer: process evaluation

De Falco M., Marrelli L., Giaconia A., Tarquini P., University of Rome “La Sapienza”, IT

The aim of this work is to present a novel hybrid plant for the production of a mixture of methane and hydrogen from a steam reforming reactor whose heat duty is supplied by a molten [...]

Johnson Space Center’s Solar and Wind-based Renewable Energy System

Vasquez A., Ewert M., Rowlands J., Post K., NASA Johnson Space Center, US

This paper will present performance data and comparisons from a 32 kW solar and wind based renewable enery system installed at the NASA Johnson Space Center. The system provides a web-based performance and weather data [...]

Thin film solar cell based on microcrystalline nanostructure silicon grown in low temperature condition

Chung Y.B., Lim J.S., Kim H., Kim J.K., Hwang N.M., Kim H., Kim J.K., Park Y.J., Seoul National University, KR

High quality microcrystalline silicon thin film grown by Hot-Wire Chemical Vapor Deposition(HWCVD) and subsequently manufactured solar cells are presented. Intrinsic layer photoconductivity data is provided for one of the film quality measures, and the result [...]

Parallel Integrated Solar Cell Circuits for Split Solar Spectrum Light Source

Li Y., Shi F., Texas A&M University, US

Among the various solar energy application technologies, the photovoltaic technology is, in particular, the most desirable technology for large-scale applications due to the fact that the solar energy in optical form is directly transformed into [...]

Large area optimized thin film nano solar cells on metal sheets

Toivola M., Peltola T., Miettunen K., Halme J., Aitola K., Lund P.D., Helsinki University of Technology, FI

We have upscaled stainless steel based dye-sensitized solar cell (DSC) from small, 0.32 cm2 active area laboratory sized test cells to 6 cm x 6 cm large area ”minimodule”. This is a continuation to our [...]

Hydrogen-Steel Compatibility Research at NIST-Boulder

Siewert T.A., Slifka A.J., McColskey J.D., Lasseigne A.N., Nanninga N.E., Levi Y., NIST, US

The National Institute of Standards and Technology (NIST) is establishing a new national test facility in Boulder, Colorado to evaluate the mechanical properties of materials proposed to store, transport, and distribute hydrogen fuels. Many of [...]

Silica Nanosprings – A Novel Nanostructured Material for Hydrogen Storage

Norton M.G., McIlroy D.N., Corti G., Miller M.A., Washington State University, US

Hydrogen storage for transportation applications remains a challenge. Current approaches are still short of published goals, in particular in being able to operate at acceptable temperatures. Physisorption, or non-dissociative approaches, where the hydrogen is stored [...]

Plasma Torch Process for Hydrogen Production at Small Distributed Stations

Miley G.H., Gough W.C., Leon H., University of Illinois, US

Small distributed hydrogen generating stations have been proposed. However, they are generally assumed to use water electrolysis units or various gas reforming processes. In this study we examine an alternate approach using the exhaust plasma [...]

Engineering High Surface Area Catalysts for Clean Tech Applications

McIlroy D.N., Corti G., Cantrell T., Beaux M., Prakash T., Norton M.G., Washington State University, US

Since catalytic performance is a limiting factor for many essential elements of the hydrogen economy, the need for improved catalysts is great. One-dimensional (1D) nanomaterials are ideal catalysts because of their large surface area to [...]
