Eliminating stranded methane for good.

Qnergy turns methane from closed landfills into high-integrity, premium carbon credits.

The Challenge

Methane is a super-pollutant.

The problem?

10,000 landfills in the US vent it freely into the atmosphere, often at concentrations too low for traditional solutions like gas-to-energy or RNG to use. These sites are typically left without a viable pathway for addressing methane emissions, otherwise known as stranded methane.

The Solution

Qnergy’s TORCH4 makes previously uneconomic methane abatement possible. Built on our Stirling engine technology, the system operates autonomously on low-grade methane from closed landfill sites, without requiring grid power. TORCH4 eliminates 99.99% of the methane it processes and permanently prevents that methane from venting into the atmosphere.

Our Model

Pure additionality. We provide the TORCH4 installation, monitoring and maintenance at no cost to the site owner. Revenue is shared with the owner, typically a local municipality, creating an economic incentive to address the emissions. The community earns twice: cleaner, safer air and a new source of income from land that was previously a liability.

High Integrity, Independently Verified​

  • Registered with the American Carbon Registry (ACR)
  • Approved under the ICVCM Core Carbon Principles (CCP)
  • First project (ACR 1064) is rated “A” by BeZero Carbon

Benefits Beyond Carbon​

  • Eliminates landfill odor
  • Lowers fire and explosion risk
  • Cuts hydrogen sulfide and volatile organic compounds in the air
  • Returns revenue to local communities

Case Study: Weber County, Utah

From liability to asset, next to a public park.

Weber County’s landfill closed in 1997, and was still emitting methane next to the county’s Archery Park. In August 2023, the county and Qnergy partnered to prevent methane from venting, generate carbon credits, and share the revenue. 

Qnergy’s Stirling engine runs on the landfill’s low-grade methane and powers the system on site, with no grid connection. The methane that was once venting next to families and archers is now permanently prevented from reaching the atmosphere. The project is registered with the American Carbon Registry (ACR1064), and the credits it generates fund the operation and return revenue to the county.

Weber County became the first county in Utah to take this approach.

“We’re taking a closed landfill that emits greenhouse gas and repurposing it. Methane is very harmful to the environment and we’re not only abating it, but harvesting it into renewable energy.”

Stephanie Russell, Economic Development Director, Weber County
