Sammanfattning : Dual fluidized bed gasification (DFBG) is the initial step towards the transformation of ligno-cellulosic materials into a raw gas, which can be further upgraded into transportation fuels, such as substitute natural gas, Fischer-Tropsch diesel, dimethyl ether, and methanol. DFBG units can be operated in two distinctly different ways, depending on whether the main product is a gas (to be refined into a transportation fuel) or heat and power (with gas as a by-product).

2. Towards sustainable energy consumption : Electricity demand flexibility and household fuel choice
Sammanfattning : Paper [I] investigates household heterogeneity in valuing electricity contract attributes that include various load controls and information sharing to induce demand flexibility. Using a stated preference choice experiment conducted with Swedish households, this paper shows that, although a large proportion of households ask for substantial compensation, some households are willing to share their electricity consumption information and require relatively lower compensation to allow load controls.

Sammanfattning : AbstractA majority of rural households in the developing world still use solid biomass fuels for cooking, which has severe negative health effects, may be expensive, time consuming, and contributes to global warming. Options for interventions aimed at improving the energy situation for households include the dissemination of improved cook stoves (ICSs), increase of households possibilities to switch to more modern fuels, for example through subsidies for LPG, as well as increase of the rate of electrification.

4. Fuel choice, fuel switching and improved cook stoves in Vietnamese households: Analysis, models and proposals for new solutions
Sammanfattning : A majority of rural households in the developing world use solid biomass fuels for cooking. This use has severe negative health effects, is often either expensive or time consuming, and contributes to global warming. LÄS MER
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.
