Integrated biomass-based production of district heat, electricity, motor fuels and pellets of different scales
Truong, Nguyen Le; Gustavsson, Leif - In: Applied Energy 104 (2013) C, pp. 623-632
Woody biomass can be used in different ways to contribute to sustainable development. In this paper, we analyze biomass-based production of district heat, electricity, pellets and motor fuels. We calculate production cost and biomass use of products from standalone production and from different...

Minimum-cost district heat production systems of different sizes under different environmental and social cost scenarios
Truong, Nguyen Le; Gustavsson, Leif - In: Applied Energy 136 (2014) C, pp. 881-893
District heat systems can contribute to the achievement of social and environmental targets and energy security. District heat production systems (DHSs) vary in size depending on heat demand, which is influenced by several factors such as local climatic conditions and the sizes of the...

Cost and primary energy efficiency of small-scale district heating systems
Truong, Nguyen Le; Gustavsson, Leif - In: Applied Energy 130 (2014) C, pp. 419-427
Efficient district heat production systems (DHSs) can contribute to achieving environmental targets and energy security for countries that have demands for space and water heating. The optimal options for a DHS vary with the environmental and social-political contexts and the scale of district...

EXPANSE methodology for evaluating the economic potential of renewable energy from an energy mix perspective
Trutnevyte, Evelina - In: Applied Energy 111 (2013) C, pp. 593-601
Several methodologies exist for evaluating the economic potential of renewable energy sources. These methodologies either cannot capture how this economic potential depends on its embedding in the whole energy mix, or provide a single cost-optimal energy mix, which is not flexible enough for...

Configuring wall layers for improved insulation performance
Bond, Danielle E.M.; Clark, William W.; Kimber, Mark - In: Applied Energy 112 (2013) C, pp. 235-245
External walls provide an important barrier between occupied building spaces and variable ambient conditions. Building insulation is often optimized for static performance based on its R-Value rating, but a growing body of literature has begun to assess the dynamic thermal performance of...
