Methane-Eating Microbes

Detailed overview of innovation with sample startups and prominent university research

What it is

Methane-eating microbes, also known as methanotrophs, are microorganisms that consume methane as their primary energy source. These microbes naturally occur in various environments, including soils, oceans, and wetlands, where they play a crucial role in regulating methane levels in the atmosphere. This innovation focuses on harnessing the power of these microbes to mitigate methane emissions from various anthropogenic sources, such as landfills, agriculture, and oil and gas operations.

Impact on climate action

Methane-Eating Microbes offer a game-changing solution under the theme of Reducing Non-CO2 Emissions. By consuming methane, a potent greenhouse gas, these microbes mitigate its impact on climate change. Their deployment can significantly curb methane emissions from various sources, contributing to global efforts in combating climate change.
