Earth naturally emits methane (CH₄) from both natural and anthropogenic sources, including wetlands, livestock, landfills, fossil fuel extraction, industrial activity and waste management. Although it has a shorter atmospheric lifetime than carbon dioxide (CO₂), methane is a far more potent greenhouse gas—approximately 28–34 times stronger at trapping heat over a 100-year time horizon, and more than 80 times stronger on a 20-year horizon, making it a major driver of climate change. Rising methane levels intensify global warming, threaten ecosystems, and contribute to air pollution through the formation of ground-level ozone.
A promising solution is to capture methane and use it as a feedstock for advanced materials. Through catalytic and plasma-based processes, methane can be converted into high quality graphene and hydrogen, a clean fuel. This approach not only prevents methane from entering the atmosphere, reducing its environmental impact, but also supports the development of many sustainable industries.
- High Quality Graphene production: Graphene, synthesized from CH₄, offers a scalable, carbon-negative pathway to supply industries with a versatile nanomaterial. Its exceptional strength, conductivity, barrier properties, and light weight make it valuable in structural composites, conductive plastics, coatings, electronics, lubricants, cement, energy storage devices, filtration membranes, medical devices, next-generation electronics and many others. Incorporating graphene into polymers or packaging materials can also reduce weight, improve performance, and extend product lifetimes—contributing to resource efficiency and reduced waste.
- Hydrogen generation: The co-production of hydrogen provides a clean fuel with zero carbon emissions at the point of use. Unlike conventional hydrogen made from steam methane reforming (SMR), methane pyrolysis for graphene and H₂ does not release CO₂, positioning it as a greener route to hydrogen supply and supporting the emerging hydrogen economy.
Using CH₄ as a feedstock to produce both high quality graphene and hydrogen offers a triple win:
- Environmental: Mitigates potent methane emissions
- Climate & Energy: Delivers clean hydrogen with minimal CO₂
- Innovation: Enables new industries and products built on graphene’s extraordinary material qualities
