1. Possibilities of CO2 emission reduction : process integration analysis and carbon trading schemes
Sammanfattning : Climate change is one of the greatest challenges faced by today's society. With more evidence from scientists, the need to manage greenhouse gas emissions has been increasing in response to international climate change negotiations. LÄS MER
2. NOx Storage and Reduction Catalysts. Reduction with Hydrogen and the Influence of Water and Carbon Dioxide
Sammanfattning : Environmental concern has increased over the past several years and resulted in stringent emission legislation on NOx, CO, and hydrocarbon emissions from automobile exhausts. Moreover, the demands to improve the fuel efficiency of engines and to lower the CO2 emissions have increased, and a way to meet this is by using lean burn engines which operate with oxygen excess.

3. Transition Metal-Based Electrocatalysts for Alkaline Water Splitting and CO2 Reduction
Sammanfattning : With excessive usage of fossil fuels and ever-increasing environmental issues, numerous efforts have been devoted to the development of renewable energies for the replacement of traditional fossil fuels to reduce greenhouse gas emission and realize the rapidly growing demand for global energy. Renewable energies, however, often show diurnal and seasonal variations in power output, forming a need for energy storage to meet people’s continuous energy supply. LÄS MER
4. A systematic approach for major renovation of residential buildings
Sammanfattning : In Sweden, buildings are responsible for about 40 % of total energy use and about 10 % of total CO2 emissions Today more than 60 % of existing Swedish residential buildings are over 40 years old and are in need of major renovation. In addition, 15 % of all multi-family buildings and 27 % of all single-family houses were built before 1945. LÄS MER
5. Oxy-Fuel Combustion - The Control of Nitrogen Oxides
Sammanfattning : Oxy-fuel combustion is one of the main candidates for carbon dioxide capture from power plants. In oxy-fuel combustion, oxygen diluted with recycled flue gas oxidizes the fuel. The elimination of air-borne nitrogen generates a flue gas that mainly consists of carbon dioxide and water. LÄS MER
