Of all of the corporate climate hype floating round this spring, ExxonMobil’s secret challenge to chop down its air pollution by mining Bitcoin has to rank up there as one of many strangest.

Exxon launched a pilot challenge in 2021 to mine Bitcoin in North Dakota’s Bakken oil fields, in accordance with reporting by CNBC in March. The US’s greatest oil and gasoline firm can also be serious about doing the identical in Alaska and elements of Nigeria, Argentina, Guyana, and Germany, Bloomberg reported. And it’s not alone. Different oil firms, including ConocoPhillips in North Dakota, see the energy-hungry cryptocurrency as a option to offload a few of their local weather footprint and perhaps make some money within the course of. The US has turn out to be the biggest hub for Bitcoin mining globally, so this may very well be a rising development.

The story of how fossil gasoline firms turned to the dirtiest cryptocurrency on the market as a option to inexperienced up their books begins with a persistent gasoline downside. At any time when any firm drills for oil, it usually pushes some methane gasoline out of the bottom, too. Methane is an much more potent greenhouse gasoline than carbon dioxide. If an organization lets that methane escape into the ambiance, which they’re embarrassingly steadily guilty of doing, methane would entice warmth with 80 occasions as a lot energy as CO2 over the subsequent 20 years. Yikes.

Oil firms will usually reinject a few of that gasoline into the bottom — not out of the goodness of their hearts however to maintain up the stress that drives oil up out of wells.

However there isn’t at all times sufficient room to place the surplus gasoline again within the floor. The choice? Mild it on hearth. Burning the methane, known as “flaring” in industry-speak, releases CO2. In relation to the local weather, it is a hurt discount strategy. Not releasing gasoline within the first place can be finest — however releasing CO2 is marginally higher than letting stronger methane float up into the ambiance.

The draw back to this — other than including to a local weather disaster that’s killing people and making total communities unlivable — is that burning methane is form of like rolling up a wad of money and smoking it. You see, methane’s advertising and marketing nickname is “pure gasoline.” Greater than $1 billion in pure gasoline goes up in smoke yearly within the US by way of flaring.

All that gasoline may very well be put to make use of as electrical energy, however that might require constructing out infrastructure. And it seems that fossil gasoline firms may be keen to take these losses reasonably than spend the (surprisingly affordable quantity of) time and money to construct pipelines to get that gasoline to market. A extra enticing choice is to place that gasoline to work on-site close to the oil effectively so there’s no have to construct a brand new pipeline to utilize the gasoline.

That is the place Bitcoin reenters the chat. The Bitcoin community makes use of about as a lot electrical energy in a 12 months because the nation of Malaysia. Miners remedy ever extra advanced puzzles to mint new Bitcoin, which requires particular {hardware} and an entire lot of electrical energy. Fortunately for Exxon and firms prefer it, Bitcoin mining rigs could be arrange just about wherever there’s an inexpensive, considerable energy supply — like, say, an oil subject the place Exxon has a lot additional gasoline it’s simply burning it up willy-nilly.

Right here’s the place we lastly get to Exxon’s potential local weather argument for mining Bitcoin. Exxon is working with an organization known as Crusoe, in accordance with CNBC, whose sole function is to assist fossil gasoline firms cope with their waste gasoline by utilizing it for cryptomining or different computing initiatives. It’s “on a mission to align the way forward for computation with the way forward for the local weather,” it says on its web site.

Crusoe crunched its personal numbers and got here to the conclusion that cryptomining cuts down CO2 emissions by a whopping 63 p.c in comparison with flaring. Crusoe says that’s as a result of its system is way more efficient at burning off all methane. Flares, it figures, solely combust 93 p.c of the methane it’s alleged to burn. The remaining escapes into the ambiance. Crusoe’s cryptomining system, alternatively, makes use of up 99.89 p.c of the methane.

Crusoe didn’t reply to interview requests from The Verge. Exxon media relations advisor Sarah Nordin declined to “touch upon rumors and hypothesis relating to the challenge” in an electronic mail to us.

Exxon’s choice to make use of the waste gasoline for Bitcoin reasonably than discovering another extra sensible use “is definitely in all probability one of many worst case situations for an infrastructure challenge,” says Paasha Mahdavi, an assistant professor of political science on the College of California, Santa Barbara.

It may be completely different if Exxon was getting its waste gasoline to the grid the place it’d serve an arguably extra vital function like heating and lighting houses. Then that extra gasoline would displace air pollution that might have in any other case come from deliberately drilling for gasoline elsewhere. However that’s not likely the case when Exxon mines Bitcoin with waste gasoline.

“Higher to be doing one thing of use with [the gas], reasonably than simply flaring it to nobody’s profit,” says Jon Goldstein, a senior director on the Environmental Protection Fund. “However on the similar time, it looks like [cryptomining is] not likely a use that’s going to do a lot good for society at giant. It’s going to profit traders in cryptocurrency.”

Different specialists are extra skeptical that that is truly a solution to the issue of waste gasoline. “That is mainly a option to monetize flaring. It’s not a option to cease flaring,” Mahdavi says.

Mahdavi additionally cautions that Exxon might probably make itself look prefer it’s reducing down air pollution on paper when it’s actually simply shifting these emissions from its personal books straight onto another person’s. At any time when Exxon flares waste gasoline, that’s a part of the corporate’s carbon footprint. But when one other firm burns the gasoline from Exxon’s oil fields for Bitcoin mining, who do the related greenhouse gasoline emissions get assigned to — the Bitcoin miners or Exxon? The solutions are nonetheless murky, Mahdavi says.

There’s one final catch with Exxon’s cryptomining, and it’s a giant one. Enabling fossil gasoline firms to revenue off waste gasoline, unsurprisingly, offers them good purpose to maintain on drilling, Mahdavi and environmental economist Raphael Calel write in a 2020 paper.

“There’s now probably an incentive to extend your drilling since you’re getting a better return,” Calel says. “All you’re going to get is an incentive for overproduction so that you simply get this additional profit downstream.”
