Flawless – More on How Hyperscalers Mitigate the Impacts of Their Fast-Rising Use of Natural Gas

There are several approaches environmentally inclined hyperscalers can take to mitigate the climate-related impacts of their increasing consumption of natural gas for data centers. These include buying and retiring environmental credits for low-methane-intensity (low-MI) gas; capturing and sequestering most of the carbon dioxide (CO2) emitted by their gas plants; developing new wind, solar and geothermal projects (either onsite or elsewhere) to offset the gas-fired generation; and buying power from existing nuclear units and/or supporting the development of new ones. In today’s RBN blog, we continue our look at what hyperscalers are doing to mitigate the impacts of their growing reliance on natural gas.

As we said in Part 1, many of the nation’s largest hyperscalers — companies like Amazon, Google, Meta and Microsoft — now acknowledge that the need to rapidly ramp up the availability of around-the-clock electricity to power their new data centers gives them little choice but to rely heavily on gas-fired generation, at least for the near term. The catch is that these gas-dependent plans conflict head-on with the companies’ long-stated “net zero” goals for greenhouse gas (GHG) emissions, so many of these same AI giants are taking aggressive steps to mitigate the environmental impact of their fast-rising gas use.

We also summarized the major hyperscalers’ stated goals for reducing GHGs and the new challenges they face in meeting those goals, and identified the primary approaches that hyperscalers are leaning into — noted just above.

Today, we will put a little more meat on those bones, focusing initially on what seems sure to be a popular tactic, namely the purchase and retirement of low-MI gas certificates (aka MiQ certificates) tied to natural gas that has been independently certified as having very low methane intensity. As we said a while back in our Drill Down Report on certified gas (aka differentiated gas), there are a variety of efforts underway in the U.S. and elsewhere to make the natural gas piece of the global energy puzzle as clean as it can be. A primary focus of these efforts is on reducing as much as possible the amount of methane (CH4) — the main ingredient in natural gas — that is released into the atmosphere along its route from the production well to the end-user’s burner tip.

There’s good reason for zeroing in on methane emissions. Methane is a particularly potent GHG, with 84 times the atmospheric heat-trapping effect of carbon dioxide (CO2) over the short term (five to 20 years). That means reducing methane emissions along the gas value chain has quick and very positive climate effects.

Certified gas is natural gas that an independent auditor has verified against a third-party standard, thereby providing a credible and transparent accounting of emissions performance. For the most part, the certified gas movement has focused on the upstream end, namely where gas is produced, either in gas-focused plays like the Marcellus/Utica and the Haynesville or crude-oil-focused plays like the Permian and the Bakken, where large volumes of associated gas (a mix of methane, NGLs and various impurities) emerges from wells with crude oil.
