Say ‘Guten Tag!’ to This New Kind of Geothermal Tech

Rob and Jesse catch up with Mark Fitzgerald, CEO of the closed-loop geothermal startup Eavor.

Over the past decade, the oil and gas industry has sharpened its drilling skills, extracting fossil fuels at greater depths — and with more precision — than ever before. What if there was a way to tap those advances to generate zero-carbon energy?

The Canadian company Eavor (pronounced “ever”) says it can do so. Its closed-loop geothermal system is already producing heat at competitive prices in Europe, and it says it will soon be able to drill deep enough to fuel the electricity system, too. It just opened a first-of-its-kind demonstration facility in Germany, which is successfully heating and powering the small hamlet of Geretsreid, Bavaria.

On this week’s episode of Shift Key, Rob and Jesse chat with Mark Fitzgerald, the president and CEO of Eavor, about how its new technology works, how it differs from other forms of advanced geothermal, and why Europe is a good test bed for heat-generating projects. We also chat about what Mark, who previously ran Petronas Canada, learned in his 35 years in the oil industry.

Shift Key is hosted by Robinson Meyer, the founding executive editor of Heatmap, and Jesse Jenkins, a professor of energy systems engineering at Princeton University.

Here is an excerpt from our conversation:

Jesse Jenkins: So at the surface, this is a very limited footprint, right? It’s a fairly small power plant, and then underground, you’ve got this kilometer-scale heat exchanger effectively that you’ve built without fracturing, but with a lot of drilling involved, right? So the key, I think, for making that work is to continually advance the economics of drilling.

What is Eavor’s strategy there for bringing down the cost of drilling these closed loops so that they become cost competitive despite the large amount of total miles drilled that you have to — or kilometers drilled that you have to put down?

Mark Fitzgerald: That’s a great point, Jesse, and I would reinforce that drilling technology, or drilling efficiency, has been something that’s been talked about and understood across the globe for a hundred-plus years. So we are not creating a new method of drilling. We are not looking for something that hasn’t been already done across any of the unconventional players in North America, any of the big drilling or service companies or operators around the globe.

What we are doing is changing the trajectory, and changing the application of that drilling methodology to create the underground radiator, as you would talk about. My background — I spent 36 years in oil and gas, a great proportion of that in the unconventional space before I had this amazing opportunity to join Eavor. And so I understand how, through sound engineering, sound geoscience, proper modeling, that cost compression will occur. One of the best examples that I point to is, we completed six laterals — so six of these horizontal wells, or these forks, at a time, connected them in Geretsreid, our first facility in Germany. The fourth and fifth laterals were done at 50% of the cost of the first two. And so already, in moving from lateral one to lateral six, we’ve seen a reduction of 50% in the cost structure.

The second is that in terms of pace of drilling, the faster you drill the lower costs you incur. The pace of drilling for us on those fifth and six laterals was three times what it was on lateral one and two.

5 Things to Keep in Mind When It’s Smoky Outside

What are the health risks? How can I protect myself? And will my plants be okay?

Smoky days.

If you live anywhere near the Great Lakes or Mid-Atlantic (or certain parts of the Mountain West), odds are it’s smoky where you live. Wildfires raging in western Ontario are sending smoke cascading south and east across the U.S., prompting widespread air quality alerts affecting millions of Americans.

The good and — very bad — news is that we’ve been here before. Here’s a look back at some of Heatmap’s coverage from the summer of 2023, when smoke produced by forest fires in Quebec blanketed 128 million people in a murky haze and turned the New York City skyline an ominous shade of orange.

1. Oil traders issue a stark warning as Trump ramps up Iran War

The resumption of fighting between the United States and Iran over the Strait of Hormuz could hammer energy markets harder than the previous phase of the conflict, as the crude stockpiles governments tapped at a record volumes to avert the worst economic impact of the war are now depleted. That’s the warning oil traders issued to the Financial Times on Wednesday. “We’ve burned through all of the buffers we had. Everything,” one trader said. “All of that’s now gone.” The gloomy assessment came as The Wall Street Journal reported that President Donald Trump has weighed expanding the U.S. military operation in Iran.

Carbon Removal

The Carbon Removal Buyer the World Has Been Waiting For

Proposed reforms to Europe’s Emissions Trading System could see the EU itself become a carbon credit customer.

The European Union is on the verge of making major changes to its carbon market, including integrating carbon removals into the scheme for the first time.

The bloc’s highest governing body, the European Commission, is expected to publish a proposal on Friday to reform the EU Emissions Trading System, or ETS, to align it with the EU’s 2040 emissions target. Under the current rules, companies cannot use carbon credits of any kind to comply with the regulations. But as 2040 grows closer, the EU plans to rely on carbon removal to offset some of the residual emissions from industries that are the most difficult to decarbonize.
