This episode explores the looming methane emissions surge driven by the rapid buildout of behind-the-meter natural gas generation for data centers. The host, Shayle Kann, and guest Olya Urzak, founder and CEO of Frost Methane, examine how upstream extraction leaks, midstream losses, and generator methane slip combine to double the warming impact of these power plants compared to CO2 calculations alone. They discuss concrete levers to mitigate these emissions, such as sourcing low-leak gas, avoiding partial-load engine operation, and installing exhaust catalysts, arguing that these steps are cheap and do not slow down deployment speeds.
Shail Khan introduces the episode, hosts Catalyst, and sets the stage for discussing methane emissions in data centers.
Olya walks through upstream, midstream, facility, and engine slip leak sources and their relative magnitudes.
Olya calculates that 50–75 GW of new gas capacity could add 380 megatons of CO₂‑equivalent, half of which is preventable.
Discussion of buying low‑leak gas, improving midstream integrity, and reducing engine slip through design and catalysts.
Explains that mitigation adds less than 1% to capital cost and doesn’t delay time‑to‑market, making it a practical lever.
Highlights that many hyperscalers undercount methane slip and the need for standardized accounting and supplier standards.
Olya envisions scaling mitigation, capturing CO₂, and offsetting as pathways to reduce emissions beyond data centers.
The guest explains that methane is 28 times more potent than CO2 over a 100-year term and 84 times more potent over a 20-year term, currently accounting for 30 percent of existing global warming.
Permian Basin Extraction Leaksdata
Upstream wellhead and midstream gathering pipe leaks in the Permian Basin result in an average of 4 percent of extracted natural gas being lost directly to the atmosphere.
Reciprocating Engine Methane Slipdata
Reciprocating engines suffer from unburned methane slipping through their exhaust at an EPA average of 3 percent at full capacity, rising up to 12 percent at partial load.
Massive Emissions Equivalentdata
Assuming 50 gigawatts of new behind-the-meter capacity with a 7.5 percent methane leakage rate, upcoming data centers would add 380 megatons of CO2 equivalent to US emissions in 18 months.
Significant Climate Impactinsight
Tackling methane on these planned data center projects could prevent emissions equal to 15 percent of total US electrical grid emissions.
Certified Low Leak Gasstrategy
Data centers can leverage their massive purchasing power to buy certified low-leak natural gas from top-tier producers like BP in the Permian Basin.
Partial Load Engine Riskinsight
The guest highlights that attempting to match data center gas generation with solar production by running engines at partial loads causes a severe surge in unburned methane slip.
“So everybody knows that it's 28 times more potent than CO2 over the 100-year terms and 84 times more potent over the 20-year terms.”
“If you're running at partial load, that can be significantly, significantly higher, right? I've seen measurements up to 12% on that.”
“We would add basically 380 megatons of CO2E to US emissions in the next 18 months for those 50 gigawatts to come online.”
“So that, let's call it 50%, that's 15% of US grid emissions is what we can prevent by building these data centers with tackling the methane in mind.”
“I don't think it would add more than a percent to the cost of the data center.”
It’s no secret that hyperscalers’ behind-the-meter gas bonanza could generate enormous CO2 emissions. But the BTM boom could become 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 - Frost Methane Labs / MERIT certification - Catalyst: The unexplored frontier of methane removal - Catalyst: Why are we still flaring gas? - Catalyst: Serving data center load with carbon capture - Catalyst: Can the fossil gas supply handle the AI boom? - Open Circuit: The off-grid data center fantasy - Latitude Media: The problem with the US gas bonanza for data centers - Latitude Media: Senate Democrats probe gas-powered AI data centers Credits: Hosted by Shayle Kann.
