Delivering leading renewable and synthetic natural gas solutions
Johnson Matthey’s expertise in methanation
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.
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.
Innovating with our methanation technology
JM’s proven methanation technology is being applied to the circular production of critical raw materials as part of the MECALO project. By leveraging our expertise in synthetic gas production and power-to-x technologies, we are enabling the decarbonisation of essential industries.
As a trusted partner in the MECALO consortium, JM continues to demonstrate its commitment to sustainability, delivering innovative solutions that support a cleaner, more secure future.
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.

Lower upfront costs with smarter design
Flexible, proven technology that minimizes capital investment and accelerates project bankability.
OPEX
Operating costs are kept low while maximising product revenues through high-efficiency CO₂ and H₂ conversion, with no purge streams or offgas. The process also generates valuable steam for power generation or other applications. With reliable technology and long-lasting catalysts, downtime and maintenance are minimised, resulting in lower lifetime operating costs.
