Unlocking the Energy Beneath our Feet: Geothermal for Energy Transition | Matt Houde | TEDxBoston

- This talk will bring the public's attention to geothermal energy as a neglected source of renewable energy, yet a perfect complementary solution to wind and solar energy for transitioning the global energy system away from fossil fuels. The talk will cover the externalities and deficiencies associated with the conventional approach to the Energy Transition (Wind + Solar + Storage), along with a brief description of geothermal energy, why it addresses the externalities and deficiencies with the conventional approach outlined prior, and how Quaise Energy is developing a novel technology gto provide access to geothermal energy, anywhere. The idea is to motivate a "Manhattan Project" like approach where the public and private sectors join forces to solve an enormous technical challenge (universal access to baseload renewable power), unlocking the enormous potential of geothermal energy as a climate solution. Matt Houde is a Cofounder at Quaise Energy and project manager for the $5M grant that Quaise, Inc., received from the Department of Energy’s Advanced Research Projects Agency - Energy (ARPA-E) to develop a new drilling technology that could allow the world to access the supercritical geothermal heat that is miles beneath our feet. Existing technologies cannot reach those depths.
Matt, who coordinated the writing of the successful ARPA-E grant, received his bachelor’s degree from the University of Wisconsin, Madison, in geological engineering. He went on to earn a master’s degree from Stanford University in civil and environmental engineering. While at Stanford, Matt was an intern for Ormat Technologies, one of the largest geothermal companies in the world.
Matt, who lives in Knoxville, TN, is passionate about developing solutions to climate change. To that end, he applauds renewable energy sources like wind and solar. But, “we need a more reliable renewable energy source that uses much less land. Supercritical geothermal fits that spot like a glove." This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at www.ted.com/tedx
Matt, you are amazing - and thank you for your mission towards creating a sustainable future!
Hi Matt, I am absolutely in awe of the technology and the possibilities. Just wondering about a few things: 1) the millimeter waves are guided to the bottom of the drilling hole. This pipe basically hangs in the hole. Eventually this pipe must be miles long. Is it able to support its own weigh at such lengths? 2) in shallow geothermical projects you drill two holes and inject a medium into one which permeates through the rock to a second hole. But I think at these depths you do not use two holes?? But still you need to get the medium down to the bottom, right and afterwards when heated, back up to the surface. How does that work with one single hole? Hopefully this will be a major contributor to the green energy transition and the energy independence!
Needless to mention, that 100 GHz waveguide loses at least 0.02 dB/m. Imagine a waveguide being 1km-long (20 dB loss). 5km-long…how will the pipe behave under 300 degC?
Rooting for Quaise!
Awesome job Matt! Go Quaise!
As a matter of fact, free energy. Peace!
How do you get flow in the active zones? If the hole is solid you will not be able to pull the stream or water out of it. At that depth and PSI it will likely be water and the flashing will create scale how often do you have to do a well job? Is it possible to run scale inhibitors into the flashing zones at that depth and temperatures? I have worked in the Geothermal Energy for 18 years steam and dietary plant. It’s very cool and exciting technology for sure but it takes a lot more than a hole.
It would be a closed-loop system that recycles the water. It would be a super-critical fluid that would clean the water used. The system works best in a non-active geological zone which is 70% of the land surface of the planet.

Very useful video 👍
Yes
And CO2 and H2s are abundant in geothermal energy how do you treat the CO2? H2s is easy to treat but the CO2 is a different story.
the well which shall take the return fluids back scales up in short time and blocks the line
No, it does not supercritical fluid is very good at cleaning water. The water is recycled and isolated from the surrounding rock by the glass liner.@@thorsrensen3162
That's will have after effects a lot of earth quake
No, because the holes produced are relatively small and where they fracture the rock is deep. They do not have to fracture the volume of rock hydraulic fracking does. A supercritical fluid behaves both as a fluid and a vapour at the same time and is more efficient at transmitting the heat
Fossil fuel ain't going no where
I predict failure
In what way are you qualified to predict the chance of it working.
She has it locked away seemingly with reason as she had even buried Carbon.
Geothermal drilling creates a radiator, a cooling at it's source. It is finite without our BS.
Sol radiates it FREELY. Get off our lazy ifs ands and but(t)s.
MAKE IT HAPPEN, less this wonderfully beautiful rock resembles one of her two sisters prematurely.
Sol will outlive us, our clumsy UN coupons and 6th grader parasitic notions. Leave her heart alone. ~DreadfulBride
1. It is relatively infinite The heat produced is by nuclear decay as well as by sunlight. 2. The centre of the Earth is hotter than the surface of the sun.
