Electrodialytic Energy Storage System: Permselectivity, Stack Measurements and Life-Cycle Analysis
(Peer reviewed; Journal article, 2020)Reverse electrodialysis and electrodialysis can be combined into a closed energy storage system, allowing for storing surplus energy through a salinity difference between two solutions. A closed system benefits from simple ... -
Heat to H2: Using Waste Heat for Hydrogen Production through Reverse Electrodialysis
(Journal article; Peer reviewed, 2019)This work presents an integrated hydrogen production system using reverse electrodialysis (RED) and waste heat, termed Heat to H2. The driving potential in RED is a concentration difference over alternating anion and cation ... -
LaNi5-assisted hydrogenation of MgNi2 in the hybrid structures of La1.09Mg1.91Ni9D9.5 and La0.91Mg2.09Ni9D9.4
(Journal article; Peer reviewed, 2015)This work focused on the high pressure PCT and in situ neutron powder diffraction studies of the LaMg2Ni9-H2 (D2) system at pressures up to 1,000 bar. LaMg2Ni9 alloy was prepared by a powder metallurgy route from the LaNi9 ... -
Life Cycle Based Climate Emissions of Charcoal Conditioning Routes for the Use in the Ferro-Alloy Production
(Peer reviewed; Journal article, 2022)Renewable reductants are intended to significantly reduce CO2 emissions from ferro-alloy production, e.g., by up to 80% in 2050 in Norway. However, charcoals provide inferior properties compared to fossil fuel-based ... -
Platinum and Platinum Group Metal-Free Catalysts for Anion Exchange Membrane Fuel Cells
(Journal article; Peer reviewed, 2020)The development of active hydrogen oxidation reaction (HOR) and oxygen reduction reaction (ORR) catalysts for use in anion exchange membrane fuel cells (AEMFCs), which are free from platinum group metals (PGMs), is expected ... -
Temperature and Velocity Effects on Mass and Momentum Transport in Spacer-Filled Channels for Reverse Electrodialysis: A Numerical Study
(Journal article; Peer reviewed, 2018)Concentration polarization is one of the main challenges of membrane-based processes such as power generation by reverse electrodialysis. Spacers in the compartments can enhance mass transfer by reducing concentration ... -
Thermal Gradients with Sintered Solid State Electrolytes in Lithium-Ion Batteries
(Journal article; Peer reviewed, 2020)The electrolyte is one of the three essential constituents of a Lithium-Ion battery (LiB) inaddition to the anode and cathode. During increasingly high power and high current charging anddischarging, the requirement for ... -
Thermodynamic Insight in Design of Methanation Reactor with Water Removal Considering Nexus between CO2 Conversion and Irreversibilities
(Journal article; Peer reviewed, 2021)The inevitable nexus between energy use and CO2 emission necessitates the development of sustainable energy systems. The conversion of CO2 to CH4 using green H2 in power-to-gas applications in such energy systems has ...
