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.

Isuzu NRR-EV gets to work as first electric trucks reach customers

Isuzu is giving Red Bull electrified wings – the iconic drinks company is officially the first to put the production version of its new-for-2025 Isuzu NRR-EV medium duty electric box truck to work in North America.

Deployed by Red Bull North America, these first-ever customer Isuzu NRR-EV medium duty trucks are busy delivering cans of Red Bull products throughout Southern California with zero tailpipe emissions, marking the first time the best-selling low-cab/cabover box truck brand in the US can make such a claim.

“Today marks a major milestone for the industry and for us. Watching the NRR-EV evolve from a concept to a viable operating product is a big deal,” explains Shaun Skinner, President of Isuzu Commercial Truck of America. “Our teams and our clients have put so much time and effort into making this happen, and it speaks to our teamwork and dedication to more sustainable transportation solutions. It is no longer just a plan, we have zero-emission trucks serving our customers’ needs!”

The NRR-EV is available with a number of different battery configurations, ranging from three 20 kWh battery packs (60 kWh total) up to nine 20 kWh battery packs, with five and seven pack options in between. The nine-pack version is good for up to 235 miles of range with a 19,500 lb. GVWR. The batteries, regardless of configuration, send power to a 150 kW (200 hp) electric motor with 380 lb-ft. of torque available at 0 rpm.

For “Red Bull” duty, the Isuzu trucks ship with a 100 kWh total battery capacity, and are fitted a lightweight, all-aluminum 6-bay beverage body, the vehicle’s design maintains its cargo capacity. The NRR-EV’s 19,500 lb. GVWR (Class 5) chassis, combined with the lightweight body and “big enough” battery spec provides Red Bull’s delivery drivers a hefty, 9,000 lb. payload.

Isuzu began assembling NRR-EV trucks at its Charlotte, Michigan assembly plant in August 2024. Customer deliveries are set to begin nationally in Q1 of 2025.

Hyundai is preparing to launch its first electric minivan: Here's what we know so far

Hyundai is gearing up to launch its first all-electric minivan. Production is set to begin next year, and the EV minivan is expected to play a key role in its global expansion. Here’s what to expect.

Hyundai will launch its first EV minivan in 2025

The Staria is Hyundai’s successor to the Starex, its multi-purpose vehicle (MPV), launched in 2021. Like its replacement, the Staria is offered in a minivan, minibus, van, pickup, and several other configurations like limousines and ambulances.

Although the Staria was launched with only diesel and gas-powered powertrain options, Hyundai added its first hybrid model in February.

Hyundai will introduce the Staria Electric, its first electric minivan, next year. In March, Hyundai unveiled its new ST1 electric business van, which is based on the Staria. However, the minivan will get its own EV model in 2025. The ST1 is Hyundai’s first commercial EV. It’s available in refrigerated van and basic chassis cab options.

Hyundai is already building gas-powered and hybrid Staria models at its Ulsan plant in Korea, but it is preparing to begin producing the EV version.

According to the Korean media outlet Newsis, sources close to the matter on Friday said Hyundai will begin converting a production line (Line 1) at its Ulsan Plant 4 for Staria Electric around January 25, 2024.

The expansion is part of Hyundai’s broader plan to introduce 21 electric vehicles by 2030, accounting for over 2 million in sales.

A report from The Korean Economic Daily in June claimed Hyundai would expand Staria EV production into Europe starting in the first half of 2026. European-made models will be sold domestically and overseas, like in Australia and Thailand. Hyundai aims to sell 15,000 to 20,000 of the EV model annually.

The Staria Electric will be powered by Hyundai’s fourth-generation 84 kWh EV batteries and will have over 10% more capacity than the ST1.

Hyundai sold 37,769 Starias through the first 11 months of 2024. Last year, Hyundai Staria sales reached 39,780, including domestic and export sales. By the end of the year, Staria sales are expected to exceed 40,000 for the first time.

Hyundai’s sister company also has big plans to expand its commercial business with a new lineup of EVs based on its PBV (Platform Beyond Vehicle). Its first electric van, the PV5, was spotted earlier this year as a potential Volkswagen ID.Buzz challenger.

Schneider electric semi truck fleet hits 6 million miles driven

Just a year after it hit the 1 million electric mile mark, Schneider National ($SNDR) and its unmistakable orange semi trucks have thrown down the gauntlet – adding more than 5 million miles to its BEV tally and crossing the 6 million electric mile mark!

The company says this latest all-electric milestone means Schneider has cut more than 20 million pounds of harmful carbon emissions. A total it says is equivalent to removing more than 2,100 gas-powered passenger cars from the road.

“Reaching 6 million zero-emission miles is a testament to our steadfast dedication to sustainability and innovation,” said Schneider President and CEO, Mark Rourke. “Leading the way in adopting electric vehicle technology not only benefits the environment but also serves as an example of the broad service capabilities and flexibility we can offer to customers.”

Schneider operates one of the largest fleets of Freightliner eCascadia electric semi trucks in the country, with fully 92 of the BEVs deployed (so far). The trucks have been operating in and around the ports of Southern California, where they have significantly reduced emissions and contributed to cleaner air quality while reliably transporting freight and saving SNDR money.

“Schneider is a great example of the kind of forward-thinking entrepreneurship our industry needs,” says David Carson, Senior Vice President, Sales and Marketing at DTNA. “They’ve achieved over 6 million zero emission miles, which is a reminder for us all to keep working on overcoming challenges together on the path to zero emissions. At DTNA, we’re committed to the shift to zero emissions, alongside pioneers like Schneider, who are showing us what’s possible.”

Fifty of Schneider’ 92 eCascadias were funded by JETSI – a California-wide initiative working to reduce greenhouse gas emissions. Of the remaining 42 five are jointly funded by the EPA’s FY18 Targeted Airshed Grant, seven are funded by the Volkswagen Environmental Mitigation Trust, and 30 are funded by California’s HVIP incentive program.

Electrek’s Take

Schneider is among the many global fleets that are proving the reliability and efficacy of battery-electric semi trucks every day, racking up millions of miles faster than many of the nay-sayers thought would be possible. The only real question facing the world of electric trucking now is whether the legacy brands like Freightliner and Volvo have established an insurmountable lead over Tesla.
