Some crypto proponents have spoken positively about using excess gas that would otherwise be flared for Bitcoin mining, though climate experts have spoken out against it being a sufficient or reasonable solution. "It's like if you had a leaky gasoline pipeline and, instead of fixing the problem, you plugged in a Humvee next to the leak and left the engine on in perpetuity with the A/C on full blast," said UC Santa Barbara professor Paasha Mahdavi.
According to Bloomberg, Exxon Mobil has begun a pilot program to set up Bitcoin miners at an oil well in North Dakota. The project reportedly runs off 18 million ft³ of natural gas that would otherwise be flared. Although early proponents waxed poetic about how anyone could mine Bitcoin, the increasing hardware specialization and massive electricity costs have made it practical at scale only for those with access to the hardware and cheap sources of electricity — including, now, the world's second largest oil company.
