… the end of 2007. The system was introduced in order to decrease the wastes of carbon dioxide and the system is a part of ratifying the Kyoto ?protocol which first period runs between 2008-2012.The idea of the system is to reduce the wastes of carbon dioxide where it costs less …
Kvantitativ undersökning av Kalmar Energis elhandelskunder
… Emission Trading System (EU ETS). It leads to progressive reduction of total carbon dioxide emissions in Europe. Kalmar Energi offers customers to obtain one EUA (equivalent to one ton of CO2) per year by paying 25 SEK a month as a KlimatEl-supplement. The purpose of this …
… the ice-free season which contributed to elevated amount of available organic carbon to be mineralized to gas during winter. The absence of a fertilization effect in the very high humic lake is most likely due to light-limitation being the key limitator in that lake, thus …
växthusgaser, energi- och resursanvändning i modellstudie
… by adjusting control parameters such as aeration, internal recycle flow, carbon addition etc. Thus the same effluent load of ammonium and total nitrogen were reached for all scenarios compared to the reference. The simulated results showed that the total use of energy (most …
? en värdering av miljöeffekter
… The environmental change in question is the change in discharge levels of carbon dioxide (CO2), nitrogen oxides (NOx), sulphur dioxide (SO2) and particle matter. It is shown that a heat and power plant solution provides the highest value of environmental change. In addition to …
… for aviation is the great amount of exhaust gases, mainly nitrogen oxides, carbon monoxide, carbon dioxide and hydrocarbons - mostly "greenhouse gases" leading to climate changes. I decided to sort out what is being done to decrease these problems and what regulations there are …
… One way to once again drive development forward while making motor sports carbon-neutral is to run the race cars on hydrogen. In this thesis, the goal is to convert a spark ignition engine for hydrogen operation. The basis for the hydrogen conversion is the current situation …
… can give an extra value for example by, local disposal of stormwater, reducing carbon dioxide and benefits to wildlife.A list of trees for present and future urban areas in the Stockholm region has been created. The list contains the parameters which describe the characteristics …

… of gas production, gas composition, content of dry matter and organic matter, carbon / nitrogen-ratio and pH have been performed.The results from lab scale digestion show that the pea residue has a methane potential of 300-400 liters of methane per kg VS during 25 days of …
Analys av framtida energisystem
… the need of purchased energy.The results show that Wapnö can reduce their carbon emissions with 5600 tons of carbon dioxide per year with a future biogas plant in operation. The results also show that the waste heat, combined with a heat pump, is the most cost efficient way to …
To reduce emissions of carbon dioxide (CO2) Carbon Capture and Storage (CCS) technologieshave been developed. Chemical Looping Combustion (CLC) is a CO2 capture technologywith the CCS framework, and at Chalmers University of Technology in Gothenburg,Sweden, a 100 kW chemical …
