The share of wind power in power systems is increasing dramatically, and this is happening in parallel with increased penetration of solar photovoltaics, storage, other inverter-based technologies, and electrification of other sectors. Recognising the fundamental objective of power systems...

In this paper, we investigate the time and frequency dynamics of connectedness among green assets such as green bonds, clean energy markets, and carbon prices. Using daily price data, we explore return spillovers across these green financial markets by applying the novel framework on time and...

This study investigates the hydrogen reduction of Nchwaning manganese ore at elevated temperatures to enhance understanding of reaction kinetics and optimize industrial applications. Experimental investigations were conducted across temperatures ranging from 600 °C to 900 °C to observe reduction...

In modeling of gas flow through porous media width adsorption, the thermodynamic properties of the adsorbed phase are usually approximated by those of the bulk liquid. Using non-isothermal, gaseous transport of moist air through a porous insulation material as example, we show that this leads to...

The glass industry stands as a significant contributor to global greenhouse gas emissions, primarily reliant on natural gas during production, posing a considerable environmental challenge. Despite advancements in furnace technologies, achieving substantial reductions in emissions remains a hurdle...

This research discusses the hydropower potential of hydraulic structures that were originally built for other uses, including hydrological and energy data. The historically known average specific water discharge of rivers in Romania is used as input data in hydropower potential determination. Recent...

Immiscible two-phase flow in porous media produces different types of patterns depending on the capillary number Ca and viscosity ratio M. At high Ca, viscous instability of the fluid–fluid interface occurs when the displaced fluid is the more viscous, and leads to viscous fingering, which is...

We theoretically study the inception and propagation of positive and negative streamers in . Our study is done in 3D, using a newly formulated kinetic Monte Carlo discharge model where the electrons are described as drifting and diffusing particles that adhere to the local field approximation. Our...

Sprite discharges are electrical discharges that initiate from the lower ionosphere during intense lightning storms, manifesting themselves optically as flashes of light that last a few milliseconds. This study unravels sprite initiation mechanisms and evolution into distinctive morphologies like...

Invert emulsion fluids where water droplets are dispersed in an oil phase are often the preferred choice when drilling through problematic formations such as reactive shales. Bulk volume of OBM is typically leased and mixed offsite and transported to the site with truck or ship to the offshore...
