South Africa is currently experiencing an energy crisis because of a mismatch between
energy supply and demand. Increasing energy demand necessitates the adequate …

The energy harvesting characteristics of actively pitching flap** foils under a two-degrees-
of-freedom (2DOF) system were investigated through numerical simulations. At a Reynolds …

Proton exchange membrane electrolytic cell (PEMEC) is considered a promising way to
produce green hydrogen due to its advantages of high current density, rapid start and stop …

Non-thermal plasma-catalytic ammonia synthesis (NTPCAS) has been regarded as a
promising route to store hydrogen by utilizing renewable electricity. Alumina is a suitable …

In a weak grid, the line impedance variation will cause the resonant frequency of the LCL
filter to shift towards lower frequencies, thus reducing the quality of the grid-connected …

This work highlights the energy implications, environmental impact, applications, and
challenges of Metal-Air Batteries (MABs). MABs are classified based on the metal anode that …

At specified Reynolds numbers Re= ρ vc/μ= 5× 10 5⁠, this study investigates the power-
extraction regime of a flap**-foil turbine executing a figure-eight trajectory. This study …

ABSTRACT PV (photovoltaic) systems have been deployed more in the recent years to
support green energy generation. In the recent era, grid tied PV has been sparked by the …

The use of renewable energy sources rises to fulfill the demand for future electricity. Clean,
