Increasing energy demands in society have led to intensive fossil fuel usage, resulting in increasing carbon dioxide (CO2) emissions, one of the most significant greenhouse gases and major contributors to global warming. Considerable efforts have been made towards CO2 capture, storage, ... En savoir plus
The "Power to Gas" technology is a promising alternative for storing renewable electrical energy through energy carriers. This technology involves using surplus energy from renewable sources to obtain green hydrogen through water electrolysis. Since hydrogen storage and transportation ... En savoir plus
The chemisorption and absorption of CO2 bubbles have been extensively studied and modeled in literature. CO2 gas is converted into aqueous CO2, which produces OH-, HCO3- and CO32- - ions in the solution. In this study, a 3D CO2 bubble column is simulated using COMSOL Multiphysics, ... En savoir plus
With the anticipated effects of global climate change upon us, induced by egregious CO2 emissions, it is imperative to implement technologies to close the carbon cycle. One potential technique to do this is storing the energy from intermittent sources (e.g. solar, wind, hydro) in the ... En savoir plus
Electrochemical reduction of CO2 to value added chemicals is a promising strategy to mitigate its emission from atmosphere and close the carbon cycle. Although the knowledge on designing electrocatalysts for CO2 electroreduction exists, challenges are associated with developing CO2 ... En savoir plus
Power-to-gas is an important area of research for reducing greenhouse gases and seasonal energy storage. Methane, with a Lower Heating Value of 50 MJ/kg, is already a commonly used gas, and its synthesis using green hydrogen production (electrolysis of renewable energy) is a remarkable ...

Modified Atmosphere Packaging (MAP) is a widely applied technology for the shelf-life extension of fresh and fresh-cut fruits and vegetables. This technique relies on modifying the gas composition inside de package by the respiratory activity of the product and the gas exchange through ... En savoir plus
Problem set up: The present study models fluid flow (CO2) in a closed system in context to CO2 sequestration in deep saline aquifers using the Sub surface flow module. A 2 dimensional heterogeneous porous reservoir (Fig. 1) 300 m x 910 m was fabricated using COMSOL Multiphysics® ... En savoir plus
Model calibration and validation were implemented using experimental data from literature. We utilized a microfluidic electrochemical cell that was configured with parallel, rectangular, and multi-layered channels, which is operating in a co-flow mode. CO2 gas stream enters the cathode ...

A model for CO2 storage is presented. It is shown that the system is highly dynamic, i.e. results depend strongly on parameter disturbances and numerical features. However, a series of scenario calculations shows that there are invariants, most important: the duration of the early ... En savoir plus
