Positive Streamer Initiation in SF6/CO2 Based on Zener's Field Ionization

Guang-Yu Sun

In this study, experiments were performed to measure the inception and breakdown voltages of SF6/CO2 mixed gases with varying mixing ratios at two different pressures (1 and 2 bar). Using the preliminary data obtained from the experiments, a 3D particle mo ...

EPFL's District Heating Heat Pump - Performance Analysis for DIfferent Working Fluids

Sylvain Clément

The present case study is multi-criteria performance analysis of EPFL’s heat pump for different working fluids. The heat pump is based on a 2-stage vapour compression cycle which is modelled using the software Belsim VALI for 7 low-GWP refrigerants. The si ...

Hydrogen Storage by Reduction of CO2 to Synthetic Hydrocarbons

Noris André Gallandat, Wen Luo, Jie Zhang, Kun Zhao

The storage of renewable energy is crucial for the substitution of fossil fuels with renewable energy. Hydrogen is the first step in the conversion of electricity from renewable sources to an energy carrier. However, hydrogen is technically and economicall ...

Snapshots of mean ocean temperature over the last 700,000 yr using noble gases in the EPICA Dome C ice core

Adrien Michel

Together with the latent heat stored in glacial ice sheets the ocean heat uptake carries the lion’s share of glacial/interglacial changes in the planetary heat content but little direct information on the global mean ocean temperature (MOT) is available to ...

Carbon dioxide capture, storage and production of biofuel and biomaterials by bacteria: A review

Edgard Gnansounou, Manish Kumar

Due to industrialization and urbanization, as humans continue to rely on fossil fuels, carbon dioxide (CO2) will inevitably be generated and result in an increase of Global Warming Gases (GWGs). However, their prospect is misted up because of the environme ...
