AI Summary
5 min readData centers’ looming methane surge
The math is stark: a behind-the-meter gas plant powering a data center can have roughly double the warming impact most people assume, because half the problem isn't the CO₂ from combustion—it's the methane that never gets burned at all. Olya Erzak, founder and CEO of Frost Methane, has mapped the full value chain and found that with 50 gigawatts of new on-site gas capacity coming online in the next 18 months, total emissions could hit 380 megatons of CO₂ equivalent. About 40 to 50 percent of that is methane. And roughly half of the total is preventable.
Where the methane comes from
The emissions chain starts before the generator even fires. In a basin like the Permian in Texas, about 4 percent of produced gas is lost at the wellhead and in the gathering pipes that carry it to processing. That number varies enormously by basin and operator: the best producers leak around 0.2 percent of production, while the worst leak far more than the average. The Marcellus basin in Pennsylvania has much lower leakage rates. Long-distance transmission pipelines, by contrast, leak negligibly.

It’s no secret that hyperscalers’ behind-the-meter gas bonanza has generated enormous CO2 emissions. But the AI boom is responsible for another, less-publicized emissions issue: upstream and onsite methane leaks that could derail decarbonization efforts.
In this episode, Shayle Kann speaks with Olya Irzak, founder and CEO of Frost Methane Labs. Olya unpacks the full lifecycle of methane emissions in gas-powered data centers, and considers why the actual warming impact of behind-the-meter gas may be double current estimates. Olya says practical, relatively low-cost strategies could cut those emissions in half. Shayle and Olya also discuss:
- The big-picture data: Why tens of gigawatts of new behind-the-meter gas capacity could generate 380 megatons of CO2 and methane emissions over the next 18 months.
- How methane can leak across the value chain, from wellheads and gathering pipelines to facility leaks and engine slippage
- How methane's extreme short-term warming potency means off-grid gas emissions could dwarf coal’s impacts over the next 20 years
- Why running gas generators at partial loads increases leaks
- Why low-leak gas procurement, leak detection and repair, and catalyst additions add less than 1% to total data center build costs without causing operational delays
- How big tech's current emissions reporting relies on averages that overlook actual leaks
