6. Modeling Aspects of Chemical-Looping Combustion for Solid Fuels
Sammanfattning : Chemical-looping combustion is a novel technology for combustion of fossil fuel. By using a circulating bed material to transfer oxygen to the fuel, a pure stream of carbon dioxide can be obtained from the flue gas, undiluted by nitrogen. LÄS MER
7. Development and characterization of functional composite materials for advanced energy conversion technologies
Sammanfattning : The solid oxide fuel cell (SOFC) is a potential high efficient electrochemical device for vehicles, auxiliary power units and large-scale stationary power plants combined heat and power application. The main challenges of this technology for market acceptance are associated with cost and lifetime due to the high temperature (700-1000 oC) operation and complex cell structure, i. LÄS MER
8. Design and Operation of a 10 kWth Chemical-Looping Combustor for Solid Fuels
Sammanfattning : The use of a 10 kWth chemical-looping combustor for solid fuels was investigated. The unit was designed, dimensioned and built and two types of fuel were tested: a South African coal and a petroleum coke from Mexico. Chemical-looping combustion is an alternative to normal combustion for CO2 capture. LÄS MER
9. Dual-ion Conducting Nanocompoiste for Low Temperature Solid Oxide Fuel Cell
Sammanfattning : Solid oxide fuel cells (SOFCs) are considered as one of the most promising power generation technologies due to their high energy conversion efficiency, fuel flexibility and reduced pollution. There is a broad interest in reducing the operating temperature of SOFCs. LÄS MER
10. Innovations in nanomaterials for proton exchange membrane fuel cells
Sammanfattning : Hydrogen technologies are rapidly receiving increased attention as it offers a renewable energy alternative to the current petroleum-based fuel infrastructure, considering that continued large-scale use of such fossil fuels will lead to disastrous impacts on our environment. The proton exchange membrane fuel cell should play a significant role in a hydrogen economy since it enables convenient and direct conversion of hydrogen into electricity, thus allowing the use of hydrogen in applications particularly suited for the transportation industry.
