Delivering leading renewable and synthetic natural gas solutions
Electrolytic synthetic substitute natural gas, also known as synthetic natural gas, (e-SNG) and renewable natural gas (RNG) offer a low-carbon alternative to fossil natural gas, seamlessly integrating into existing gas infrastructure.
At Johnson Matthey (JM), we apply over a century of expertise in synthetic gas technology to provide efficient, scalable, and commercially proven solutions for synthetic natural gas production.
Our DAVY ePOWERGASTM licensed methanation flowsheet, combined with our proven methanation catalysts, ensures reliable, efficient, and cost-effective production of RNG and e-SNG.
Our technology drives down the levelized cost of gas production:
Reduced project risk through optimised execution
Streamlined delivery, robust design choices, and proven performance help keep projects on track and on budget.
Johnson Matthey strengthens project certainty by applying standardised, widely available equipment and well-established process designs. This approach lowers procurement risk and shortens delivery schedules. The technology’s compatibility with variable renewable power enables stable operation without large buffering systems, further reducing capital requirements. With decades of successful project delivery, JM provides dependable, finance-ready solutions that support efficient execution and cost control.
Lower lifecycle costs. Greater operational efficiency.
High-performance processing, stable long-term operation, and valuable energy recovery support improved project economics.
Operating efficiency is maximised through high-conversion processing that eliminates waste streams and avoids the need for complex gas handling. The system generates useful steam that can be integrated into plant utilities to offset energy demand. Supported by durable catalysts and reliable plant performance, operators benefit from reduced maintenance requirements and fewer interruptions, helping to drive down total lifecycle operating costs.
Johnson Matthey’s expertise in methanation
With over 100 licensed SNG plants and more than a century of research in the field, JM is a trusted leader in power-to-gas solutions. Our advanced methanation technology supports:
-
Flexible feedstock conversion: Accommodating CO2, CO, and gasified biomass.
-
Scalability: From small to large-scale commercial plants
-
Global deployment: Successfully implemented across multiple geographies
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.
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:
