The Intergovernmental Panel on Climate Change (IPCC) has estimated that anthropogenic global warming is already 1.0 °C above pre-industrial levels, and it is likely to reach 1.5 °C between 2030 and 2050.1 Carbon dioxide (CO2) is widely regarded as the greenhouse gas with the largest impact on global.
This paper assesses a concept of a highly efficient energy storage system based on high temperature electrolysis for the production of H2 and the catalytic methanation of CO2 for the production of synthetic CH4, paired with.Using power to produce energetic gases such as hydrogen and methane is an old idea that is making a comeback as renewable power generation surges. These flexible energy carriers or gaseous fuels offer an energy storage solution to cover times of weak wind and sunlight.

Why synthetic natural gas? It''s the "multitool" of energy transition. After the first step of producing green hydrogen with water electrolysis, the hydrogen has to be utilized. In most locations with significant renewable energy production, some kind of storage for later use is required – when neither sun nor wind generate enough energy

Synthetic natural gas (SNG) is one of the promising energy carriers for the excessive electricity generated from variable renewable energy sources. SNG production from renewable H 2 and CO 2 via catalytic CO 2 methanation has gained much attention since CO 2 emissions could be simultaneously reduced.
The future development of natural gas prices is therefore highly relevant for PtG methanation plants. No significant changes in the natural gas price are expected until 2030 by [42]. [43] states that there are still large crude oil and natural gas reserves that can be mined at low cost. Only political measures can ensure the use of PtG.
It is estimated that certain end use sectors including metals refining, biofuels, synthetic hydrocarbons, natural gas supplementation (e.g. blending hydrogen into natural gas pipelines), seasonal energy storage for the electric grid, and transportation/vehicle usage have a large latent demand in the United States, that could support a hydrogen
You can use synthetic natural gas (SNG) in the existing gas infrastructure without any modifications. This gives this method an obvious advantage. CO 2-neutral renewable energy is used to power an electrolysis plant, breaking water down into hydrogen and oxygen. The resulting hydrogen can be added to the natural gas grid or used as a fuel for
The costs of synthetic natural gas (SNG) production for larger units typically range from 42 to 133 €/MWh SNG. The levelized cost of SNG production for the considered systems aligns with the reported range. 3.3. Sensitivity analysis (with respect to biomass price, electricity price and location)

Pathways to produce synthetic (or substitute) natural gas starting from renewable energy sources are thus relevant to decarbonize all those energy sectors heavily depending on fossil gas. In 2011, much of the new installed (electric) capacity in Europe came from RES 1 : solar PV installed 21,000 MWe (46.7% of total new capacity), followed by
The production of synthetic natural gas (SNG) to store renewable energy in a chemical energy carrier can be accomplished basically through three main production pathways: the biochemical (biogas upgrade), thermochemical (gasification and synthesis gas upgrade) and electrochemical (''Power-to-Gas'') pathway.
