21. Advanced In-Core Fuel Cycles for the Gas Turbine-Modular Helium Reactor
Sammanfattning : In 1789 a German chemist, Martin Heinrich Klaproth, announced the discovery of a new element: uranium; few years later, the head of father of the modern chemistry, Antoine Lavoisier, was swept away by guillotine: a new era was destined to be opened, either where energy would have been produced in large scale by nuclear processes delivering hundreds of times the energy of chemical processes or where a mass of people, revolutionary or not, would have been melted down into a couple of seconds. After a quite long time, on the 2nd December 1942, the first nuclear reactor has been put into operation by Enrico Fermi in Chicago; few years later, came also the dark side utilization of fissile materials in Hiroshima and Nagasaki.

22. Conceptual Design of Semi-Closed Oxy-Fuel Combustion Combind-Cycle
Sammanfattning : Accelerating actions to mitigate CO2 emissions was one of the important messages at the UN Climate Summit 2014. About 85 % of the world’s energy is provided through the burning of fossil fuels, which is the main source of CO2 emissions. LÄS MER
23. Thermodynamic Properties of CO2 Mixtures and Their Applications in Advanced Power Cycles with CO2 Capture Processes
Sammanfattning : The thermodynamic properties of CO2-mixtures are essential for the design and operation of CO2 Capture and Storage (CCS) systems. A better understanding of the thermodynamic properties of CO2 mixtures could provide a scientific basis to define a proper guideline of CO2 purity and impure components for the CCS processes according to technical, safety and environmental requirements.

24. Integrating Biomass in Existing Natural Gas-Fired Power Plants
Sammanfattning : Using biomass for utility heat and electricity generation can supplement use of fossil fuels, whose emissions of carbon dioxide likely risk causing serious climate change and ocean acidification. Biomass as energy source is a limited resource and when used as fuel in thermal power plants this currently results in higher production costs than using fossil fuels such as natural gas and coal.

25. Oxy-Fuel Combustion Combined Cycles for Carbon Capture
Sammanfattning : A short and medium term method to decrease carbon dioxide emissions is carbon capture and storage. This method captures carbon dioxide from point sources of emissions and then stores the carbon dioxide in geological formations. LÄS MER
