Quaise Energy is on a mission to prove that deep geothermal drilling could provide more than enough clean energy to meet the world’s needs as we move away from fossil fuels. Matt Houde, cofounder at Quaise Energy, explained its potential at the TEDX Boston Planetary Stewardship Event last week.

The aim of the Boston event, which was timed to run at the same time as COP27 in Egypt, was to “spotlight actionable ideas for human activity to achieve a sustainable relationship with the planet’s natural systems,” according to TEDX Boston’s website.

Deep geothermal’s potential

Houde, a speaker at TEDX Boston, explained why deep geothermal has so much potential:

The total energy content of the heat stored underground exceeds our annual energy demand as a planet by a factor of a billion. So tapping into a fraction of that is more than enough to meet our energy needs for the foreseeable future.

But we can’t yet drill deep enough to unlock that energy. Houde continued:

If we can get to 10 miles down, we can start to find economic temperatures everywhere. And if we go even deeper, we can get to temperatures where water [pumped to the site] becomes supercritical, [a steam-like phase that will allow] a step change improvement in the power production per well and so cheapen the cost of energy.

The deepest hole that’s been drilled to date, the Kola borehole in Russia, is 7.6 miles deep. It took 20 years to complete because conventional equipment like mechanical drill bits break down at those depths.

“And the truth is, we’ll need hundreds if not thousands of Kola boreholes if we want to scale geothermal to the capacity that’s needed,” Houde said. He went on to assert that Quaise:

[I]s developing technology to blast rock with microwaves to potentially drill the deepest holes on Earth. And no, I’m not stealing a plot device from Star Trek. This technology is real and has been proven in [an MIT] lab.

Deep geothermal’s possibility

Houde explained the benefits of deep geothermal energy in general. These include being available 24/7, which “can help balance out the intermittent flows of wind and [solar].” Deep geothermal plants also won’t need much land. Houde illustrated this with an artist’s rendition of a future rig next to truck shipping containers (see main photo).

Houde also said that deep geothermal is “the perfect energy source to take advantage of the largest workforce in the world, the oil and gas industry.” That industry has “11 million jobs in the US alone, and a skill set that is exactly what’s needed for geothermal to rapidly scale.”

Drilling with microwaves

Quaise is working to replace conventional drill bits with millimeter wave energy – cousins to the conventional microwaves we heat up our leftovers with. Those millimeter waves literally melt then vaporize the rock to create ever-deeper holes.

Scientists developed the general technique at MIT over the last 15 years, and proved that millimeter waves could actually drill a hole in basalt. The gyrotron machine that produces the millimeter wave energy has been used for around 70 years in nuclear fusion research.

Quaise’s technique also uses conventional drilling technologies developed by the oil and gas industry. The company will use these to drill down through surface layers – what they were optimized for – to basement rock – which millimeter waves can easily power through.

Houde explained that millimeter waves “are ideal for the hard, hot, crystalline rock deep down that conventional drilling struggles with.” They’re not as efficient in the softer rock closer to the surface, but “those are the same formations that conventional drilling excels at.” That’s why Quaise applies a hybrid approach to the problem.

Challenges remain

There are still several challenges that Quaise has to tackle in order to scale its technology, including a better understanding of rock properties at great depths. Further, Houde said, “we need to advance the supply chain for gyrotrons” and the waveguides that carry their energy downhole. That equipment is currently optimized for specialized one-off projects in fusion research. For deep geothermal applications, they must be produced in quantity and be robust and reliable in a field environment.

There are also engineering challenges that must be addressed. Houde said:

Chief among them is, how do we ensure full removal of the ash [created by the process] and transport that ash up the borehole over long distances?

Progress so far

In the MIT lab, engineers drilled a hole in basalt with a 1:1 aspect ratio – 2 inches deep by 2 inches in diameter. Quaise built upon MIT’s results by scaling up the power density of the microwave beam and the depth of the hole by a factor of 10 to achieve a 10:1 aspect ratio. The company is now building the first field-deployable prototype millimeter-wave drilling rigs.

Houde said:

Our current plan is to drill the first holes in the field in the next few years. And while we continue to advance the technology to drill deeper, we will also explore our first commercial geothermal projects in shallower settings.

XPeng at Beijing Auto Show: 2K pure vision ADAS, neural network, 1km/sec fast charging, and a new AI-driven EV sub-brand [Video]

XPeng Motors kept things relatively short but sweet during its 20-minute presentation at the 2024 Beijing International Auto Show earlier today, but there’s a lot to get excited about following several updates from XPeng founder, chairman, and CEO He Xiaopeng, including an “entirely new breed” of EVs under a new sub-brand. Here’s the full recap.

Today’s presentation in front of a crowd in Beijing (you can view it in its entirety below) started off simply recapping much of the same news we reported on in 2024, some of it dating back to the Chinese automaker’s annual Tech Day in October 2023.

XPeng CEO He Xiaopeng spoke in front of an X9 multi-purpose vehicle (MPV), a growing segment of luxury minivans in China. Xiaopeng highlighted much of the early success of XPeng’s first MPV model, which is versatile in that it can be configured to seat seven passengers or four, with room to transport five bikes.

As a popular BEV model amongst Chinese celebrities and athletes, XPeng’s CEO used the X9 as the vessel to highlight some of the advanced technologies it has been working on, including expansions of its XNGP ADAS technology, including new AI Valet and bodyguard functions. The automaker’s founder and chairman spoke to these technologies and what they mean for the future of EVs:

We are proud to demonstrate XPeng’s technological innovation prowess, through which we are laying a pathway to greater inclusion and equality in smart mobility. The next decade will be a ‘golden decade’ of smart vehicles. The core of smart vehicle advances is how to operate with automative software adoption emerging as the new industry norm. Looking ahead, XPeng will roll out the on-road testing of AI-powered functions integrated into XPeng models.

  • XPeng Beijing
  • XPeng Beijing

To support XNGP and other ADAS functions, XPeng used the Beijing Auto Show to share plans to deploy what it calls the “industry’s first mass-produced 2K pure visual neural network large model in vehicles.” This news confirms previous rumors we reported that XPeng was abandoning LiDAR sensors in favor of pure vision, similar to Tesla FSD.

These upgrades to perception and planning/control models will utilize over two million high-definition grids to reconstruct worlds around XPeng BEVs, ensuring that any and all surrounding objects and obstacles are identified quickly and effectively. The new technology is further supported by neural-network-based planning models, which can learn, think, and perform actions like the human mind.

According to the Beijing press conference, such neural technologies enable XPeng to deliver more human-like, self-learning vehicles that will rely heavily on AI moving forward. That includes the automaker’s latest operating system, XOS 5.1.0, which delivers several new AI-powered features to debut in the X9 before reaching other eligible XPeng EVs on May 20, 2024.

Those updates include the previously mentioned AI Valet Driver, upgraded surround reality (SR) perception capabilities, ask expanded function and learning capabilities of the automaker’s in-car AI assistant. We recommend checking out the video below for a real-world view of this technology being demonstrated.

XPeng’s new sub-brand will be called MONA

Last month, we shared news that XPeng had plans for a new EV sub-brand that focused heavily on artificial intelligence, as mentioned above, and well beyond. During the recent China Electric Vehicle 100 Summit, XPeng Chairman and CEO He Xiaopeng vowed to invest RMB 3.5 billion (~$492M) in the automaker’s “AI-enabled smart driving” technology in 2024 for R&D and the hiring of 4,000 new employees.

Xiaopeng also said the next decade of EVs will be one of intelligence and smart driving technology. As such, the new brand was in the works to deliver AI-centric tech at an affordable price for all, targeting MSRPs around RMB 100,000-150,000 ($14,000-$21,000).

At the time, we reported the unnamed sub-brand would launch in China soon as XPeng promised it will “create a new breed of AI-powered Smart EVs for young customers worldwide.” Today in Beijing, XPeng confirmed the new sub-brand is called MONA, which stands for “Made Of New AI.”

The company’s CEO said MONA will officially be introduced this June, so stay tuned for more details on that.

Last but not least, XPeng shared updates in regard to its charging technology, low-altitude flying car arm AeroHT, and its recent cooperation agreement signed with Volkswagen Group. On the charging side of things, XPeng says it is planning to upgrade its 800 kW DC fast chargers in Q3 2024, enabling what could potentially be the best charge speeds in the industry.

The automaker says the upgrades to the facilities will enable XPeng EVs to add more than 1 km (.62 miles) per second. AeroHT’s flying car was on display next to other XPeng EVs in Beijing after turning plenty of heads at CES in January. The eVTOL arm’s other vehicle, the modular flying car, is still seeking airworthiness certification and is expected to begin pre-sales in China in Q4 2024.

That’s all for now. As promised, here is the full XPeng press conference from the Beijing Auto Show, translated to English:

Toyota preps new large electric SUV, is this the Highlander EV we've been waiting for?

Another fully electric large Toyota SUV is on its way. Toyota announced it’s preparing its three-row electric SUV as part of a new $1.4 billion investment in Indiana. Is this the electric Toyota Highlander EV we’ve been waiting for?

A new large Toyota electric SUV is coming to the US

Since 2021, Toyota has invested 18.6 billion in its US operations. The new $1.4 billion will go toward its Princeton facility as it prepares to assemble its first three-row electric SUV.

Toyota has invested $8 billion in Indiana so far. The new funding will create an additional 340 new jobs. The Indiana plant employs over 7,500 workers who assemble the Toyota Sienna, Highlander, Grand Highlander, and Lexus TX.

Toyota revealed it would launch a new three-row electric SUV in the US last May as part of ten new EVs set to roll out globally.

However, that electric SUV will be built at its Kentucky plant, set for production next year. A spokesperson clarified (via Automotive News) that this new three-row electric SUV will be a separate, larger model.

Is it the Toyota Highlander EV?

Earlier this month, David Christ, the GM of Toyota’s US division, told CarBuzz, “You’re going to see more BEVs from us in the future.”

According to Christ, this will include a fully electric Toyota Highlander three-row EV. Holland confirmed it will be a “chassis-based” vehicle rather than a skateboard-based EV platform.

Toyota said the new investment will also add a battery pack assembly line for lithium-ion batteries. The batteries will be supplied from its new EV battery plant in North Carolina, slated to go online in 2025.

The Japanese automaker sold over 32,000 Highlanders and 25,136 Grand Highlanders in the US during the first three months of 2024.

Meanwhile, Toyota has only sold 1,897 bZ4X models, its sole EV in the US through March. The news comes after Toyota announced an additional $1.3 billion investment in its KY plant in February.

Toyota is also considering an electric Tacoma and Tundra but is watching demand for rivals like the Ford F-150 Lightning and Rivian R1T.
