Methane bounty hunters.

Big Picture

Methane (CH4) seeps out of many sources, from Arctic permafrost to cow burps, but the biggest sources of all are coal mines and gas wells. Methane doesn’t hang around the atmosphere as long as CO2, but while it’s up there it generates 84x more warming per molecule. Flaring it results in 98% less atmospheric warming over a decade than if the gas were simply allowed to escape into the atmosphere.

How it Works

Frost Methane develops a fleet of distributed, remote flares at abandoned and active coal mines, as well as natural sources. The devices convert high-flow methane sources into water and CO2. Careful engineering, real-time alerts, and an automatic relight mechanism limit maintenance and keep costs to one-tenth of competing systems. This generates methane offsets they sell to regulated industries.

Unfair Advantage

Their flares combust methane at 10x lower capex than other productive uses of the gas. They also operate unattended in highly inhospitable conditions with minimal maintenance for many years. Carbon markets will pay 25x more for flared methane than they do for CO2 offsets, and now they offer predictability too: California-Quebec Cap & Trade officially selected mine methane as an offset type.
