1. Energy transition in transportation : Applying TIMES-based energy system optimisation models to sub-national levels
Abstract : Transportation is embedded in the fabric of society and a key enabler of socio-economic development, but it is also a major source of carbon dioxide (CO2) and local air pollution (AP). Cities collectively account for around three quarters of total energy-related CO2 emissions, and the negative health impacts from local APs are most felt in dense urban environments. READ MORE

2. The future load curve of the Swedish building stock – Interactions between the heating load and district heating
Abstract : In line with global efforts directed against climate change, the building sector is required to undergo significant changes in terms of its energy management. This is the case for both the use of energy (reduced energy consumption) and the supply of energy (heat and electricity), and how these two interact. READ MORE

3. Future District Heating Interactions – Modelling Impacts of Industrial Excess Heat Utilisation and Energy Efficient Buildings
Abstract : International goals for climate change mitigation plus energy security targets could be met cost-effectively by interactions between different parts of energy systems. The fourth generation of the district heating systems concept was developed as an attempt to accelerate district heating (DH) systems’ interactions with other energy systems. READ MORE

4. Capturing Swedish Industry Transition towards Carbon Neutrality in a National Energy System Model
Abstract : Industry is responsible for approximately 30 % of the total emissions of greenhouse gases, both globally and in Sweden. Given the climate targets set out in the Paris agreement, the industry is facing a challenging future, requiring effective policies to aid the transition. READ MORE

5. Multi-Disciplinary Conceptual Design of Future Jet Engine Systems
Abstract : This thesis describes various aspects of the development of a multi-disciplinary aero engine conceptual design tool, TERA2020 (Techno-economic, Environmental and Risk Assessment for 2020), based on an explicit algorithm that considers: engine performance, engine aerodynamic and mechanical design, aircraft design and performance, emissions prediction and environmental impact, engine and airframe noise, and production, maintenance and direct operating costs.As part of this research effort, a newly-derived semi-empirical NOx correlation for modern rich-burn single-annular combustors is proposed.
