Utilisation of Renewable Electricity to Produce Synthetic Methane

open access: yesEnergies, 2023
This study demonstrates the production of synthetic methane or synthetic natural gas via methanation of carbon dioxide (CO2), which could replace natural gas. For the power-to-methane (P2M) process, a simulation of two-stage methanation with simultaneous

Modelling and Simulation of Methanation Catalytic Reactor for Renewable Electricity Storage

open access: yesChemical Engineering Transactions, 2013
Storing renewable electricity in a natural gas grid is an innovative concept. Renewable energy (wind or solar power) is stored as chemical energy in existing storage capacities, which is an advantage over hydrogen.

Flexible NiRu Systems for CO2 Methanation: From Efficient Catalysts to Advanced Dual-Function Materials

open access: yesNanomaterials, 2023
CO2 emissions in the atmosphere have been increasing rapidly in recent years, causing global warming. CO2 methanation reaction is deemed to be a way to combat these emissions by converting CO2 into synthetic natural gas, i.e., CH4.

Simultaneous CO 2 and CO methanation using microbes [PDF]

open access: yes, 2018
ABSTRACT In this study, we developed a method for simultaneous bio-methanation of CO 2 and CO with H 2 in a single bioreactor using a combination of carboxydotrophic bacteria and methanogenic archaea for industrial applications.

Construction of Sabatier Volcanoes for CO<sub>2</sub> Hydrogenation to C1-2 Oxygenates Using Data-Efficient Machine Learning. [PDF]

open access: yesAdv Sci (Weinh)
A new data‐efficient framework combining DFT calculations, a neural network model, and automated graph analysis of catalytic reaction networks is proposed and applied to CO2 hydrogenation on transition metal nanoparticles. The analysis shows how efficient C2 oxygenate production requires a balance between CHx formation, C–C coupling, protonation, and ...

Carbon Nanofiber Supported Ni Catalysts for CO Methanation

open access: yes, 2011
Carbon nanofiber (CNF) supported Ni catalysts (Ni/CNFs) were prepared for CO methanation. The activity of the catalyst was compared with the Ni catalyst supported by the commonly used gamma-Al2O3(Ni/gamma-Al2O3).
