2. 1. Natural resources and sustainable energy : Growth rates and resource flows for low-carbon systems

   Author : Simon Davidsson; Mikael Höök; Gert Jan Kramer; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; low-carbon technology; renewable energy; energy transitions; critical materials; energy metals; material flows; net energy; EROI; life cycle assessment; LCA; growth curves; curve fitting; resource depletion; Natural Resources and Sustainable Development; Naturresurser och hållbar utveckling;

   Abstract : Large-scale deployment of low-carbon energy technologies is important for counteracting anthropogenic climate change and achieving universal energy access. This thesis explores potential growth rates of technologies necessary to reach a more sustainable global energy system, the material and energy flows required to commission these technologies, and potential future availability of the required resources.

   Abstract : Throughout history, major rivers and shared water bodies have allowed civilizations to flourish, and the effective management of shared water bodies has always been a priority for societies and nations. Today, about 40% of the world’s population lives in proximity to the 286 transboundary river and lake basins that supply 60% of the world’s freshwater flows and make up about half of the Earth’s land area.

6. 4. Exploring low-carbon development pathways for Bolivia - A model-based analysis focused on the energy sector

   Author : Jenny Gabriela Peña Balderrama; Viktoria Martin; Mark I. Howells; Dilip Khatiwada; Francesco Gardumi; Pachauri Shonali; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Decarbonization; Sustainability; Techno-economic analysis; Bolivia; Energy access; Energy security; Systems analysis; Energy Technology; Energiteknik;

   Abstract : Global emissions have continued to rise steadily at levels exceeding the 1.5°C climate stabilization target. Therefore, the increase in the average global temperature and climate change will be determined by how we handle greenhouse gas (GHG) emissions over the next years. READ MORE

7. 5. Norbornadienes for Solar Thermal Energy Storage and New Applications

   Author : Ambra Dreos; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; thermal energy storage; molecular logic; Solar energy; molecular switch- es; energy conversion; quadricyclane; molecular keypad locks; norbornadiene;

   Abstract : The energy demand worldwide is steadily increasing, therefore it is fundamental to efficiently utilise renewable energy resources. Energy storage technologies are partic- ularly relevant in order to be able to exploit renewable energy resources such as solar energy, since these are typically intermittent and not evenly distributed.
