At the time, it was the most powerful artificial explosion in human history…but it wasn’t supposed to be. On March 1st, 1954, the United States detonated the country’s first thermonuclear or fusion bomb at Bikini Atoll in the Marshall Islands, a small coral reef and 23 islands almost equidistant from Australia, Japan, and Hawaii. In the days and weeks following the blast, the United States would pay out millions of dollars in settlements, thousands of islanders would be evacuated and re-evacuated, and the Japanese public would deem the test “a second Hiroshima,” a comparison no citizen would dare make lightly.

This video explores the revolutionary wave energy technology from CorPower, a leading Swedish energy startup. We delve into how CorPower’s innovative, bio-inspired engineering techniques capture up to three times more energy from ocean waves compared to traditional methods. Discover how their ground-breaking technology could potentially lower costs below those of wind and solar energy, setting a new standard in renewable energy efficiency. Learn more about the future of sustainable power with CorPower’s wave energy devices.

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.

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.

Geothermal power is the perpetual also-ran of renewable energy, chugging along in the background for decades, never quite breaking out of its little niche, forever causing energy experts to say, “Oh, yeah, geothermal … what’s up with that?”

Well, after approximately 15 years of reporting on energy, I finally took the time to do a deep dive into geothermal and I am here to report: This is a great time to start paying attention!
  

After many years of failure to launch, new companies and technologies have brought geothermal out of its doldrums, to the point that it may finally be ready to scale up and become a major player in clean energy. In fact, if its more enthusiastic backers are correct, geothermal may hold the key to making 100 percent clean electricity available to everyone in the world. And as a bonus, it’s an opportunity for the struggling oil and gas industry to put its capital and skills to work on something that won’t degrade the planet.

Vik Rao, former chief technology officer at Halliburton, the oil field service giant, recently told the geothermal blog Heat Beat, “geothermal is no longer a niche play. It’s scalable, potentially in a highly material way. Scalability gets the attention of the [oil services] industry.”

In this post, I’m going to cover technologies meant to mine heat deep from the Earth, which can then be used as direct heat for communities, to generate electricity, or to do both through “cogeneration” of heat and electricity. (Note that ground-source heat pumps, which take advantage of steady shallow-earth temperatures to heat buildings or groups of buildings, are sometimes included among geothermal technologies, but I’m going to leave them aside for a separate post.)

Before we get to the technologies, though, let’s take a quick look at geothermal energy itself.

Winter temperatures in Alliance, Nebraska can drop to -20°F (the record low is -40°F/C), but retired mailman Russ Finch grows oranges in his backyard greenhouse without paying for heat. Instead, he draws on the earth’s stable temperature (around 52 degrees in his region) to grow warm weather produce- citrus, figs, pomegranates – in the snow.

Finch first discovered geothermal heating in 1979 when he and his wife built it into their 4400-square-foot dream home to cut energy costs. Eighteen years later they decided to add a 16’x80′ greenhouse in the backyard. The greenhouse resembles a pit greenhouse (walipini) in that the floor is dug down 4 feet below the surface and the roof is slanted to catch the southern sun.

To avoid using heaters for the cold Nebraska winter nights, Finch relies on the warm underground air fed into the greenhouse via plastic tubing under the yard and one fan. Finch sells a “Citrus in the Snow” report detailing his work with his “geo-air” greenhouses and says anyone can build a market-producing greenhouse for about $25,000 or “less than the cost of a heat system on a traditional greenhouse”. https://greenhouseinthesnow.com/

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.
