What are synthetic and renewable natural gases?
e-SNG, also known as e-methane or e-NG, is produced by reacting electrolytic (green) hydrogen with captured CO2 from industrial and biogenic sources. Renewable natural gas, on the other hand, can also be derived from upgrading biogas, commonly produced via anaerobic digestion.
Both gases are chemically equivalent to natural gas, enabling a smooth transition to renewable energy without the need for new infrastructure.
By replacing fossil-derived natural gas with synthetic and renewable natural gases, industries and energy providers can significantly reduce carbon emissions while maintaining energy security and operational efficiency.
Supporting the energy transition with synthetic and renewable natural gases
As the world transitions to sustainable energy, synthetic and renewable natural gases plays a crucial role in transforming the global gas supply. Governments, industries, and energy providers are increasingly seeking viable alternatives to fossil natural gas that maintain grid reliability and energy security while reducing greenhouse gas emissions. Key drivers for adoption include:
Infrastructure compatibility
Both gases can be integrated seamlessly into existing natural gas networks, avoiding costly infrastructure overhauls.
Renewable energy integration
e-SNG enables surplus renewable electricity to be converted into storable, transportable gas, supporting grid stability and energy storage needs.
Energy security
Diversifies energy supply by enabling domestic and renewable gas production, reducing reliance on imported fossil fuels.
