1. 1. Enabling industrial energy benchmarking : Process-level energy end-use, key performance indicators, and efficiency potential

   Författare :Elias Andersson; Patrik Thollander; Magnus Karlsson; Martin Patel; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy efficiency; energy efficiency potential; energy benchmarking; manufacturing industry; key performance indicators; industrial energy end-use;

   Sammanfattning : One of the greatest challenges of our time is global climate change. A key strategy for mitigating the emission of greenhouse gases is the improvement of energy efficiency. Manufacturing industry stands for a large share of global energy end-use but has yet to achieve its full energy efficiency potential. LÄS MER

3. 2. Challenges for end-use energy efficiency

   Författare :Frances Sprei; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; technological development; Swedish building sector; downsizing; Energy efficiency; fuel consumption; market barriers;

   Sammanfattning : The scientific community has reached close to a consensus that anthropogenic emissions of greenhouse gases are causing a change of the global climate. These emissions arise foremost from the burning of fossil fuels, and secondly from land use change. LÄS MER

4. 3. Applicability of thermal energy storage in future district heating system - Design methodologies and performance evaluations

   Författare :Yichi Zhang; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; low-temperature district heating; demand-side management; low energy buildings; Thermal energy storage; district heating; variable renewable energy;

   Sammanfattning : District heating (DH) enables efficient and economical utilization of energy resources to satisfy the heat and hot water demands in buildings and is, thereby, well-established in Northern European countries. To achieve the future renewable energy system, the current DH systems are proved to undergo transitions towards the future DH systems, with major characteristics including renewable-based heat sources, low temperature networks, lower heating demands and smart controls.

   Sammanfattning : Buildings are the largest energy-using sector in the world. Since the generation of energy is highly associated with greenhouse gas emissions, contributing to climate change, there is a large focus on reducing energy use in buildings. LÄS MER

7. 5. Renewable Energy in Energy-Efficient, Low-Pollution Systems

   Författare :Bengt Johansson; Miljö- och energisystem; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydrogen; ethanol; methanol; rape methyl ester; biomass; renewable energy; cogeneration; energy efficiency; scenarios; air pollution; carbon dioxide; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp;

   Sammanfattning : Energy use accounts for the dominating fraction of total sulphur dioxide (SO2), nitrogen oxide (NOx), volatile organic compounds (VOCs) and carbon dioxide (CO2) emissions. In this thesis, different strategies for reducing these emissions are evaluated, using a bottom-up approach. The thesis is divided in two parts. LÄS MER
