2. 1. Hydrogen Storage Materials : Design, Catalysis, Thermodynamics, Structure and Optics

   Author : Carlos Moysés Graça Araújo; Rajeev Ahuja; Ole Martin Løvvik; Uppsala universitet; []
   Keywords : Materials science; Hydrogen-storage materials; Density functional theory; Molecular dynamics; Catalysis; Thermodynamics; Optics; Materialvetenskap;

   Abstract : Hydrogen is abundant, uniformly distributed throughout the Earth's surface and its oxidation product (water) is environmentally benign. Owing to these features, it is considered as an ideal synthetic fuel for a new world energetic matrix (renewable, secure and environmentally friendly) that could allow a sustainable future development.

4. 2. CO2 storage in deep saline aquifers : Models for geological heterogeneity and large domains

   Author : Liang Tian; Auli Niemi; Fritjof Fagerlund; Simon Mathias; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; CO2; Carbon Capture Storage; Storage Capacity; Injectivity; Monte Carlo; Gaussian; Permeability; Upscaling; 二氧化碳; 地質封存; 高斯仿真; 滲透係數; 非均質性; 升尺度; 存儲效能; 場地模擬; 不確定性; 壓力累積;

   Abstract : This work presents model development and model analyses of CO2 storage in deep saline aquifers. The goal has been two-fold, firstly to develop models and address the system behaviour under geological heterogeneity, second to tackle the issues related to problem scale as modelling of the CO2 storage systems can become prohibitively complex when large systems are considered.

5. 3. Hybrid energy storage systems : Capacity optimization and environmental implication of hybrid energy storage systems in renewable power systems

   Author : Yang Jiao; Daniel Månsson; Alfred Rufer; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

   Abstract : Electricity production contributes a large share of greenhouse gas emissions that lead to climate change. At present, power generation in many parts of the world still heavily depends on fossil fuels. To prevent global warming, the electricity sector is supposed to transition from the current fuel mix to renewable energy sources. READ MORE

6. 4. Load Shifting and Storage of Cooling Energy through Ice Bank or Ice Slurry Systems : modelling and experimental analysis

   Author : Marino Grozdek; Per Gunnar Lundqvist; Michael Kauffeld; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; refrigeration systems; cool thermal energy storage system; ice; modelling; simulation; field measurement; experiment; indirect system; ice-on-coil system; external melt; ice slurry; homogeneous storage; heterogeneous storage; Thermal energy engineering; Termisk energiteknik;

   Abstract : Ice based Cool Thermal Energy Storage (CTES) systems have attracted much attention during last few decades. The reasons are mainly of economical and environmental nature. READ MORE

7. 5. Off-gassing from thermally treated lignocellulosic biomass

   Author : Eleonora Borén; Markus Broström; Sylvia H. Larsson; Peter Björklund; Lorenz Gerber; Henrik Antti; Capucine Dupont; Umeå universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Torrefaction; steam explosion; enclosed storage; CO; CO2; O2 depletion; VOCs; Tenax-TA; SPME; process settings; storage temperature; storage time;

   Abstract : Off-gassing of hazardous compounds is, together with self-heating and dust explosions, the main safety hazards within large-scale biomass storage and handling. Formation of CO, CO2, and VOCs with concurrent O2 depletion can occur to hazardous levels in enclosed stored forest products. READ MORE
