Drilling that Anyone Can Love, or At Least, Like

Clean energy that even fossil fuel flunkies can get behind.
Google’s backing gives big mo to geothermal play.

Video above has some interesting engineering details.

Mathew Zeitlin in Heatmap:

The political coalition that has been assembled in support of advanced geothermal is bipartisan, but uni-regional: If you drew a broad strip from Las Vegas to Albuquerque and then dragged it north to the Canadian border, you would envelop Utah and Idaho (not to mention Arizona and big chunks of Wyoming and Montana). This stretch of John McPhee country includes some of biggest swaths of federal land — and some of the hottest rocks beneath it — in the country.

And so Senators Martin Heinrich of New Mexico, Catherine Cortez Masto of Nevada, Mike Lee of Utah, and James Risch of Idaho have found themselves crossing party lines, working together on a bill to encourage more production of geothermal energy, which the unique contours of this area make (potentially) especially abundant.

The Geothermal Energy Optimization Act, introduced last week, is a kind of test case for how a bipartisan energy policy could work. It combines deregulation with support for a non-carbon energy resource that leans heavily on expertise in the oil and gas industry while also not committing to any new spending.

But the bill isn’t just a victory for bipartisanship, it’s also a victory of geology. Thanks to tens of millions of years of plates sliding beneath each other and mountains collapsing, “you have a relatively thin crust before you get to that heat,” as Ben Serrurier, head of government affairs at Fervo, the enhanced geothermal startup, told me. (Fervo has operations in both Nevada and Utah.)

The bill would establish a “categorical exclusion” from environmental reviews under the National Environmental Policy Act for some geothermal activity, including exploration, i.e. the drilling of wells to see whether a particular site is suitable for a geothermal project.

The law would both expand a provision of the Energy Policy Act of 2005, which established a categorical exclusion for some oil and gas projects, and write up a new one especially for geothermal. The bill would also require the Bureau of Land Management to have regular geothermal lease sales.

The 2005 bill was written at a time when an oil-industry-friendly White House wanted to make the country more energy self-sufficient, and deregulation oil and gas activities was an obvious way to do so. The GEO Act comes during another period of intense interest in energy policy, but not one in which the paramount goal is smoothing away obstacles to hydrocarbon extraction. Today, the United States is the biggest oil and gas producer in the world (thanks to hydraulic fracturing and horizontal drilling, technology that’s used in “enhanced” geothermal energy projects) and both the White House and the Democratic Party are friendly to non-carbon energy.

But while existing tax credits have been successful in boosting wind and solar deployment, there is still need for so-called “clean firm” technologies, energy resources that can provide power at all hours of the day, no matter the weather.

By speeding up and adding some certainty to the permitting process, the bill’s provisions would “enable us to raise capital and move forward with more projects on a faster timeline,” explained Serrurier. “We already face challenges trying to raise project finance,” he said. “Then we show them the permitting timeline.”

  1. Another EGS approach is to drill deeper down to 20km at 500 ° C at using established drilling technology followed by newly developed drills that use high-power millimeter waves that can penetrate basement rock. This approach is potentially more efficient and also provides broader site selection opening up opportunities to repurpose existing thermal power plants’ heat source from fossil fuels to geothermal.

    1. right, I asked Wilson Ricks about this and he said it’s matter of if they can get the cost down to be competitive. I don’t think I posted that part of our interview but I’ll see if I can find it.


  2. What about earthquakes? Is that more of a problem with fracking because of forcing wastewater down, or is it a risk here as well.


    1. I asked about this, will see if I can find the clip, but I think the answer is that the association with earthquakes relates to the pressurized disposal of fracked water into deep wells under pressure, rather than the fracking process itself.


      1. A geothermal project in the German Alps was cancelled after a swarm of earthquakes (not catastrophic, I think, but enough to worry people.) Those living in ‘Basin and Range’ country are probably well accustomed to tremors. It’s a moot point whether injecting water into hot, faulted rock would lubricate it to produce harmless, minor movements that release tension, or prime it for the Big One. Further research is needed! (The Icelanders benefit from geothermal everything, offset by lava busting out occasionally and wrecking the place. A thick crust has its charms too.)


    2. I don’t know the specific technical issues, but fracking for oil is done in weaker rock like shale or slate. Geothermal goes after harder, more stable rock formations. AIUI, you push water down a fracked oil well to push the oil out, whereas in fracked geothermal you just want to circulate a fluid through cracks in deep hot rock.
