Comparison of methods for finding the capacitance of a supercapacitor
(Journal article; Peer reviewed, 2021)A carbon-based supercapacitor is usually associated with a capacitance such that the user can access its ability to store electrical charge. Three different measurement methods or variations thereof are typically employed ... -
Effect of relative permeability hysteresis on reservoir simulation of underground hydrogen storage in an offshore aquifer
(Journal article; Peer reviewed, 2023)Underground hydrogen storage (UHS) in porous media is proposed to balance seasonal fluctuations between demand and supply in an emerging hydrogen economy. Despite increasing focus on the topic worldwide, the understanding ... -
Impact of gas type on microfluidic drainage experiments and pore network modeling relevant for underground hydrogen storage
(Journal article; Peer reviewed, 2024)Underground hydrogen storage (UHS) in geological reservoirs is proposed as a technically feasible solution to balance mismatch between supply and demand in emerging markets. However, unique hydrogen properties and coupled ... -
Modelling supercapacitors using a dynamic equivalent circuit with a distribution of relaxation times
(Peer reviewed; Journal article, 2019)Supercapacitors are often modelled using electrical equivalent circuits with a limited number of branches. However, the limited number of branches often cannot explain long-term dynamics, and one therefore has to resort ... -
The nonlinearities in the galvanostatic charging curves of supercapacitors provide insights into charging mechanisms
(Journal article; Peer reviewed, 2022)Supercapacitors are often charged using constant currents. The capacitance can be determined from the slope of the voltage-time curve if the measured voltage over the supercapacitor increases linearly with time. However, ... -
The self-discharging of supercapacitors interpreted in terms of a distribution of rate constants
(Journal article; Peer reviewed, 2021)Supercapacitors are prone to self-discharging, which is most often measured as a voltage decrease with time under open circuit conditions. It is of substantial interest to find simple and general methods to extract information ...
