Qnergy
Qnergy is an Ogden, Utah cleantech manufacturer that builds Free Piston Stirling Engine generators to mitigate methane emissions at the source. Its PowerGen systems turn waste methane and other gaseous fuels into reliable, grid-quality remote power - and can destroy methane while doing it - serving oil and gas operators, landfills, livestock farms, and other off-grid sites worldwide. Led by cleantech veteran Ory Zik, the company has deployed thousands of units, abated millions of tonnes of CO2e, and is expanding into landfill gas abatement and voluntary carbon markets.
BioSqueeze Inc.
BioSqueeze Inc. is a Butte, Montana company and the self-described world leader in commercial biomineralization. Its core technology pumps low-viscosity, self-diverting fluids carrying naturally occurring soil bacteria into oil and gas wells, where the microbes precipitate crystalline calcium carbonate (limestone) to permanently seal leakage pathways as small as one micron. The result is a gas-tight barrier that eliminates sustained casing pressure and stops fugitive methane emissions, helping operators meet well-integrity and environmental obligations across producing, plugged, and storage wells.
NevadaNano
NevadaNano (Nevada Nanotech Systems, Inc.) is a Sparks, Nevada company that builds MEMS gas sensors and hardware-enabled SaaS for detecting flammable gases and quantifying methane and other emissions. Its patented Molecular Property Spectrometer (MPS) measures the thermodynamic properties of a gas mixture instead of relying on chemical reactions, delivering multi-gas detection with a 15-year life and no field calibration. The MPS platform powers flammable, refrigerant, methane, and hydrogen sensors, and underpins MethaneTrack, a continuous methane-monitoring system used to cut LDAR costs and meet OGMP 2.0 reporting requirements.
