A Game-Changing Vision for Geothermal Energy

A new possibility: Drilling miles down for geothermal energy by using a focused beam of microwave energy  rather than a mechanical drill bit 

According to a report released in 2019 by the U.S. Department of Energy, geothermal electricity generation could increase more than 26-fold by 2050—reaching 60 GW of installed capacity. That may seem like a pipe dream to some power observers, but if new well-drilling techniques allow enhanced geothermal systems to become economical, the reality could be much greater. In fact, Quaise Energy, a company working to develop enabling technologies needed to expand geothermal on a global scale, claims as much as 30 TW of geothermal energy could be added around the world by 2050.

“That’s where the drilling technology that we’re proposing comes into play. We’re basically trying to do directed-energy drilling with millimeter waves,” Araque said. “Imagine a microwave source on the surface, it’s called a gyrotron. We beam this energy through a pipe into the hole. Together with this energy, we push a gas—could be nitrogen, could be air, could be argon, if necessary—and at the bottom of that pipe, this energy comes out, evaporates the rock, and the gas picks up the vapor of that rock and pulls it back out. What comes out of the hole looks like volcanic ash, and the hole actually burns its way down, you know, five, six, 10, 15, 20 kilometers, as needed, to get to the temperatures we’re looking at.”

The fundamental physics behind the technology has been proven, now Quaise Energy is moving from the lab to installing a prototype in the field. “Over the next three years, we’re going to be working with key people in the oil and gas industry—one of them is one of the largest drilling contractors in the oil and gas industry—and hand in hand working with them to actually show that this is not only a good idea, but it’s actually a viable idea. We’re going to be doing this in the western United States,” said Araque.

EMERGING INFORMATION ABOUT POSITIVE ENERGY FUTURES





Superhot Rock Geothermal

Superhot rock geothermal energy is a visionary technology deserving of investment, and yet almost entirely unrecognized in the decarbonization debate. It has the potential to meet long-term demands for zero-carbon, always-on power, and can generate hydrogen for transportation fuel and other applications. Unlocking the potential of this energy source could expand our options and potentially carve a path forward to replace fossil fuels.

Superhot rock energy could support rapid global decarbonization

One promising element in a strategy to reduce greenhouse gas emissions

From: Just Have a Think on YouTube

 

Science tells us there’s enough energy in the first 10 kilometres below our planet’s surface to provide all our energy needs for millions of years. The Romans tapped into it for their hot water spas. Today, we all know it as Geothermal Energy. There’s no carbon dioxide emissions and no air pollution with geothermal, and it’s literally right there beneath our feet. So why isn’t our entire planet powered by it? Help support this YouTube channel’s leading edge reporting at http://www.patreon.com/justhaveathink  and please visit http://www.justhaveathink.com

Solar Power


New solar power technologies emerging:

Imagine a city that’s actually a vast solar energy harvesting system. A team of Michigan State University researchers has developed a technology that can turn transparent surfaces, from building windows to cell phones, into solar collecting surfaces – without obstructing the view.

Europe could import up to a fifth of its electricity from solar and wind parks in North Africa and the Middle East by 2050, and the CEO of a Germany-based consortium studying the expensive project says stakeholders must act, or face a jump in power prices.

The Desertec Industrial Initiative, set up in Germany in 2009, says Europe could import up to a fifth of its electricity from desert regions, saving $46 billion per year, according to a report in Climate Spectator.

Deserts get more power from the sun than can be used by mankind in a year, Desertec claims.

The problem is how to harvest that energy.”
