Quaise Energy

These granite core samples are helping us unlock the most valuable #geothermal heat resources for power generation and industrial demand. Our millimeter wave drilling technology is optimized for the deep basement layer of the Earth’s upper crust, where you’ll find hard, crystalline rocks. Millimeter waves are at the cutting edge of what's possible for deep drilling and geothermal energy. Core sections like these reveal the minerals and lithologies we will encounter in our drilling field trials. Each mineral phase in a rock like granite absorbs, transmits, and reflects millimeter waves differently—affecting how quickly and efficiently we can drill. The drilling rate directly affects the overall economics of superhot geothermal energy. A better understanding of the rocks we are drilling into is crucial for bringing terawatts of clean power online in record time.

Our new analysis of data from the Electric Reliability Council of Texas (ERCOT) highlights a looming warning from the Lone Star State. The analysis by Charlotte "Coco" Wallace looks at ERCOT data from 2022 and 2023 to demonstrate the reliability challenges of operating a grid solely based on solar, wind, storage, and existing nuclear power—resulting in more infrastructure generating less efficient energy on vastly more land. Dig deeper ⬇️ - Just meeting average demand would require a 3.4x solar and wind overbuild and a 42.4x increase in storage capacity - A 3.4x overbuild in Texas would require about as much space as Lake Michigan - Texas could generate reliable, renewable power for the whole state by focusing on #geothermal Read the full ERCOT Analysis and Insight: https://lnkd.in/g_DrJcRj

A deep geothermal pilot plant for the single largest gold-producing complex in the world. Quaise and the Barrick-operated Nevada Gold Mines (NGM), a joint venture with Newmont Corporation, are exploring additional decarbonization of NGM’s TS Power Plant by using geothermal heat from NGM’s land and subsurface holdings to hybridize on-site power generation. “We continue to pursue initiatives that economically reduce our reliance on carbon-based electricity sources,” said Henri Gonin, Managing Director of Nevada Gold Mines. “Quaise offers a unique prospective solution to hybridize our on-site power generation with clean geothermal heat.” The partnership underscores the unique capabilities of deep geothermal to decarbonize heavy industrial sectors like #mining, and marks the first commercial pilot for retrofitting a fossil fuel power plant to accommodate #geothermal heat.

All that ablated rock has to go somewhere. Our millimeter wave drilling process creates very small rock particles that must be removed from the borehole. To do so, a circulating purge gas sweeps downhole to the drilling front and carries all the particulates to the surface. The exhaust system then collects our disposed rock onsite and stores it for removal. Designing a highly effective exhaust system is crucial for superhot #geothermal energy. A clean borehole is essential for maximizing production out of each well and ensuring safe operations for decades to come.

It’s time to reimagine #geothermal energy. Our new Levelized Cost of Energy (LCOE) calculator and interactive map show, for the first time, how superhot geothermal developed with millimeter wave drilling makes geothermal more accessible and cost-effective across the United States and, consequently, the world. The LCOE calculator and map allow you to compare projected costs at varying well depths and temperatures anywhere in the contiguous United States. No other approach could make geothermal energy cost-competitive, or even possible, east of the Mississippi.

A better way to remove deeply drilled rock: compressed air. Our millimeter wave drilling process cannot rely on conventional techniques like drilling mud to remove rock cuttings. Drilling mud interferes with our waveguide and the millimeter waves themselves. The solution is to circulate a purge gas, or compressed air, throughout the process. Gases such as nitrogen and argon are ideal to flush downhole, sweeping all the vaporized rock away from the drilling front and up to the surface for removal. The purge gas system allows us to use millimeter wave drilling at unprecedented depths, unlocking deep #geothermal energy to decarbonize civilization within a generation.

“Exciting finding: extreme heat & pressure can help create better enhanced geothermal systems [EGS],” says Peter Massie of the Cascade Institute, commenting on a recent publication in Nature Communications led by EPFL, with support from Quaise and others.   The resulting data are among the first to show that superdeep rock can form fractures that connect and make it more permeable. Until now, geologists were divided as to whether this was possible. It all means superhot geothermal could become “much more economic,” says Geoffrey Garrison, our VP of Operations. Elizabeth Thomson reports on the findings and what they mean for the future of #geothermal energy.   Dig Deeper ⬇️   - Rock under high pressures and temperatures—more than 375 C, or 707 F—is ductile, or gooey, as opposed to a smashable stone from your backyard - Superdeep fractured rock is 10x more permeable than cracked rock found much closer to the surface - Superhot geothermal can deliver 5-10x more power than typically produced today from EGS systems and do so for up to two decades https://lnkd.in/eMiZwm6q

In Japanese culture, kintsugi is the art of repair. Artists use golden lacquer to mend damaged pottery, infusing new purpose and meaning into old structures. The clean energy transition requires a similar mindset. In our October Insights, we take a deeper dive into fossil fuel infrastructure. A truly sustainable energy transition leverages existing resources to reduce waste and accelerate buildout. Geothermal is the kintsugi of renewable energy, it is the source most capable of transforming fossil fuel infrastructure for a clean energy future. Dig deeper ⬇️ - Around 80% of global energy still comes from fossil fuels - Wind and solar require a whole new landscape of infrastructure - About 200 wells have been drilled annually for geothermal energy worldwide - Whereas 20,000 wells have been drilled annually for oil and gas in the U.S. alone - The potential of drilling more wells for geothermal is enormous Read the full Insight: https://lnkd.in/erweVpCE

Oil and gas infrastructure is key to accelerating the clean energy transition. Scale and speed are paramount to reach net zero emissions by mid-century. The global oil and gas industry has a 150+ year head start and boasts the largest workforce in energy today. Geothermal is the only renewable energy source capable of leveraging it all for a sustainable future. Drilling for geothermal is remarkably similar to drilling for oil and gas. Our millimeter wave drilling system is designed to integrate with conventional oil and gas drilling rigs to create more geothermal power plants in less time. We don’t need to reinvent the wheel (or the rig). Similar infrastructure requires similar skills to do the job. We don’t need to build an extensive workforce from scratch; oil and gas workers can readily transfer their skills and subsurface expertise to geothermal. Talk about a win-win. Geothermal provides 24/7 clean energy for a reliable and sustainable future. Leveraging oil and gas infrastructure is how we accelerate the global buildout.

A truly sustainable energy transition uses less land, not more.   In our September Insights, we examine the global land squeeze predicted over the coming decades. Several competing priorities will vie for the same finite land, such as nature, agriculture, and urbanization. Energy infrastructure is a particular tipping point, and the choices we make about clean energy sources will ease or exacerbate the world's land budget.   Deep geothermal is one of the only clean energy sources capable of creating more power on less land, compared to other renewables such as solar and wind.   Dig deeper ⬇   - Half of all land on Earth is needed to protect biodiversity - We need an additional area twice the size of India to feed humanity by 2050 - Wind and solar need at least 10x more land per unit of power produced than coal or natural gas - Deep geothermal uses a fraction of the land of other energy sources   Read the full Insight: https://lnkd.in/g-xZBP6u
