Abstract

Electrolytic hydrogen offers a promising alternative for long-term energy storage of renewable energy (RE). A stand-alone RE system based on energy storage as hydrogen has been developed and installed at the Hydrogen Research Institute, and successfully tested for autonomous operation with developed control system and power conditioning devices. The excess energy produced, with respect to the load requirement, has been sent to the electrolyzer for hydrogen production. When energy produced from the RE sources became insufficient, with respect to the load requirement, the stored hydrogen was fed to a fuel cell to produce electricity. The RE system components have substantially different voltage-current characteristics and they are integrated through power conditioning devices on a dc bus for autonomous operation by using a developed control system. The developed control system has been successfully tested for autonomous operation and energy management of the system. The experimental results clearly indicate that a stand-alone RE system based on hydrogen production is safe and reliable. Index Terms--Electrolyzer, energy storage, fuel cell, hydrogen, photovoltaic (PV), wind energy.

12. Pathway for Hydrogen in Urban Transit System.

Abstract

According to the Intergovernmental Panel on Climate Change (IPCC), the average global temperature has risen over the last century. The changes in climate could adversely impact human health, agriculture, water resources, and ecosystems. Most national and international agencies have concluded that our use of carbon-rich fuel is responsible for global warming through the greenhouse effect. Automotive exhaust emissions are the largest single source of air pollution in the world today, especially in urban areas. Natural gas, a fossil fuel that offers substantial advantages over oil-derived fuels, can facilitate the transition to hydrogen fuel. Advanced natural gasfueled vehicles have the potential to reduce carbon monoxide and reactive hydrocarbon emissions substantially compared to gasoline vehicles. Further environmental benefits can be realized by using a blend of natural gas and hydrogen. Such an approach will help create an infrastructure for an eventual transition to hydrogen.

23. Development of a dipole probe for the study of dielectric properties of biological substances in radiofrequency and microwave region with time-domain reflectometry

Author

Bose, Tapan K., Bottreau, Andre Marie, and Chahine, Richard

Abstract

A Time-Domain Reflectometric (TDR) technique with a needle-like dipole probe is described for dielectric measurements of biological substances. The probe is tested by measuring some known liquids, The dielectric measurements made on beef muscle and fat compare favorably h it h existing literature values of human muscle and fat.
