CuO–NiO/Co3O4 hybrid nanoplates as highly active catalyst for ammonia borane hydrolysis
(Peer reviewed; Journal article, 2020)Dehydrogenation of hydrogen-rich chemicals, such as ammonia borane (AB), is a promising way to produce hydrogen for mobile fuel cell power systems. However, the practical application has been impeded due to the high cost ... -
Graphene inclusion effect on anion-exchange membranes properties for alkaline water electrolyzers
(Peer reviewed; Journal article, 2020)The main issues facing the development of Anion Exchange Membranes (AEM) are the low hydroxide ion (OH−) conductivity compared to protons (H+), and the thermal and chemical stability. Based on the its unique two-dimensional ... -
Local entropy generation and entropy fluxes of a transient flame during head-on quenching towards solid and hydrogen-permeable porous walls
(Peer reviewed; Journal article, 2021)Premixed H2-air flames are studied in a one-dimensional wall-bounded configuration. The laminar flame propagates towards and quenches at a wall that is either solid or permeable. Entropy generation by each of 19 elementary ... -
Pathways to low-cost clean hydrogen production with gas switching reforming
(Peer reviewed; Journal article, 2020)Gas switching reforming (GSR) is a promising technology for natural gas reforming with inherent CO2 capture. Like conventional steam methane reforming (SMR), GSR can be integrated with water-gas shift and pressure swing ... -
Scaling factors for channel width variations in tree-like flow field patterns for polymer electrolyte membrane fuel cells - An experimental study
(Peer reviewed; Journal article, 2021)To have a uniform distribution of reactants is an advantage to a fuel cell. We report results for such a distributor with tree-like flow field plates (FFP). Numerical simulations have shown that the width scaling parameters ... -
Ternary NiCoFe nanosheets for oxygen evolution in anion exchange membrane water electrolysis
(Peer reviewed; Journal article, 2022)Tuning nickel-based catalyst activity and understanding electrolyte and ionomer interaction for oxygen evolution reaction (OER) is crucial to improve anion exchange membrane (AEM) water electrolyzers. Herein, an investigation ... -
Value of green hydrogen when curtailed to provide grid balancing services
(Peer reviewed; Journal article, 2022)This paper evaluates the potential of grid services in France, Italy, Norway and Spain to provide an alternative income for electrolysers producing hydrogen from wind power. Grid services are simulated with each country's ... -
Zero-cost partial decarbonization of natural gas via molten salt pyrolysis
(Peer reviewed; Journal article, 2023)Partial decarbonization of natural gas has the potential to kickstart the hydrogen economy. Up to 20% hydrogen volume can be safely accommodated in existing natural gas networks, removing the problem of insufficient ...
