US start-up Emvolon has developed a technology using repurposed automotive engines to convert methane-rich waste gases into liquid fuels.
Emvolon uses the engines as chemical reactors and targets methane from landfills, wastewater facilities and industrial sites at the source.
Emvolon says that, while traditional infrastructure can require costly pipelines and large processing plants, its approach could make smaller and dispersed methane sources commercially viable.
For recyclers and waste operators, the technology offers another route for difficult-to-use waste gases. Its modular design could suit sites without major energy infrastructure.
Reviving waste gas
The system uses compact, containerised units at waste sites that convert methane-rich biogas into products including methanol.
Emvolon’s innovative process combines methane conversion with existing engine technology. This differs from conventional methanol production, which typically relies on larger industrial facilities.
On-site processing also reduces the need for pipelines or long-distance transport. Emvolon is targeting applications across heavy industry sectors including shipping and aviation.
Energy security opportunity
The company estimates that more than 480 billion cubic metres of methane is wasted globally each year. Landfills, farms and industrial operations account for part of this unused resource.
‘Energy security and supply chain resilience and sustainability dictate that we produce essential liquid fuels locally,’ said Emvolon ceo Emmanuel Kasseris.
Commercial prospects
Emvolon was founded in 2021 and is inspired by research at the Massachusetts Institute of Technology (MIT). The spin-off is now moving towards commercial deployment and is building its first commercial system in North America.
To scale up, Emvolon has partnered with Montauk Renewables and Freepoint Commodities.
