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.

GM hydrogen: the reports of my death are greatly exaggerated

GM has scrapped plans to build $55 million hydrogen fuel cell factory in Detroit, triggering a tsunami of headlines about the General’s future plans for hydrogen. The reality? GM isn’t scaling back its hydrogen efforts. It’s thinking bigger.

The reports of my death are greatly exaggerated.

MARK TWAIN (sort of)

Like the great Sam Clemens, there seems to be plenty of confidence in the greater automotive press that GM’s decision to cancel a $55 millions fuel cell plant on the former Michigan State Fairgrounds site in Detroit. That plant, a JV with Southeast Michigan’s Piston Automotive, would have created ~140 jobs and built compact hydrogen fuel cells for light- and medium-duty vehicles under the Hydrotec brand.

That plan, frankly, was never going to work. It was always a cynical incentive grab and the first fruits of GM’s Hydrotec efforts were so laughably far behind the state of the electric art that the facts themselves blurred the line between satire and reality. Which, of course, didn’t matter – as long as the incentive money (Biden’s Department of Energy awarded GM $30 million in grants for the State Fairgrounds plant) kept flowing.

The new Trump Administration put an end to that flow last week, however, terminating 321 financial awards for clean energy worth $7.56 billion.

“Certainly the decisions of the DOE are an element of that overall climate but not the only driver,” explained GM spokesperson, Stuart Fowle, in a statement. “We want to prioritize the engineering talent and resources and everything we have to continuing to advance EVs given hydrogen is in a different spot.”

That spot is heavy-duty, off-highway, maritime, and data centers.

Bigger trucks, bigger fuel cells

Instead of dying, GM is continuing on the hydrogen fuel cell it’s been on for literal decades – with no plans (publicly, at least) to shutter its Fuel Cell System Manufacturing joint-venture with Honda in Brownstown Township, MI.

That company is not just developing HFCs, they’re out there selling fuel cells today, to extreme-duty, disaster response, and off-highway equipment customers operating far enough off the grid that access to electricity is questionable and to data center developers for whom access to a continuous flow of energy is mission-critical.

Electrek’s Take


Fuel cells like the ones from GM and Honda will continue to seem like a good idea … for about as long as it takes the heavy equipment guys to watch a ZQUIP video.

Want EV charging at your apartment, as an owner or a renter? Click here (update)

Want EV charging at your apartment, as an owner or a renter? Click here (update)

EVs are great, and can unlock more transportation convenience with the ease of charging at home. But for apartment-dwellers, this can be a complicated conversation. So a nonprofit called Forth is here to help, through its Charge at Home program.

One of the main benefits of an electric vehicle is in the convenience of owning and charging the car in the place it spends most of its time. Instead of having to go out of your way to fuel it, you just park it at home, in the same place it spends at least 8 hours a day, and you leave the house every day with a full charge.

But this benefit only applies to those with a consistent parking space which they can easily install charging at. When talking about owners who live in apartment buildings, it can sometimes get more complicated.

While certain states have passed “right to charge” laws to give apartment-dwellers a solution for home charging, apartment charging is nevertheless a bit of a patchwork solution so far.

And as a result of this, EV ownership among apartment renters lags behind that of single-family homeowners. It’s clear that apartments are holding back people from buying EVs, and that’s bad – lots of people live in apartments, and the gas those cars use pollutes the air just as much as any other.

Certain areas where EVs have hit a point of critical mass (namely, the large California cities) have pretty good EV ownership among renters, but it could still be better. And residents are clamoring more and more for easy EV charging in apartment communities.

So, Forth, a nonprofit advocating for equitable access to clean transportation, set up a program called Charge at Home, which is meant to connect renters, apartment building owners or other decisionmakers with resources to help install chargers at multifamily properties.

The site lets you select your situation – a resident or a decisionmaker for a new or existing multifamily development – and then gives you access to tools for your specific situation, whether you be a resident and developer.

The site houses links to help design a multifamily project, find electricians, inform you about right to charge laws or available incentives, and provide case studies, among others.

Charge at Home also hosts roundtable webinars periodically, and includes a library of past webinars with the information you need.

There are a lot of considerations for each of these projects, so it can be helpful to have someone with experience to help you go over it all. Personally, when talking to friends about getting an EV, charging considerations are usually the thing that takes up the bulk of the conversation.

So if the toolkits are still too daunting for you, Charge at Home is offering free charging consultations for multifamily developers, owners, property managers and HOAs.

The charging consultations will last through at least April 2026 – but it wouldn’t hurt to get your requests in soon. Forth may still offer consultations afterwards, but it all depends on funding availability (the program was previously funded by the Department of Energy, which has taken a turn). Regardless, the website will remain up for people to submit questions and find information, whether or not free consultations stick around.

But at the very least, as Forth points out, whether a multifamily development is interested in having EV charging at this moment or not, any developer should think about having the infrastructure, conduit and capacity ready to go for future install of EV chargers, and should consider the needs of current residents who are likely already considering EVs today.

It’s going to be necessary to install this capacity at some point, and doing so earlier can help save money down the line, make your development more attractive to renters today, and allow more renters to make the switch to cleaner transportation which helps air quality and to reduce climate change, both of which harm everyone on the planet.

Head on over to Forth’s Charge at Home site to get access to all the above resources – and to sign up for a consultation before the end of April if you’re a multifamily developer, owner, property manager or HOA.

Update: This article has been updated to account for an extension in program availability.

Electrek’s Take

I’ve long said that the only real problem with EVs is the problem of access to consistent charging for people who don’t have their own garage. Whether this be apartment-dwellers, street-parkers or the like, the electric car charging experience is often less-than-ideal outside of single family homes, at least in North America.

There are workarounds available, like charging at work, or using Superchargers in “third places” where you often spend time, but these still aren’t optimal. The best thing is just to charge your car wherever it spends most of its time, which is your home. When you do that, EVs outshine everything in convenience.

We’ve highlighted some projects before which showed how reasonable it can be to install charging for developments. Every project is going to have its complexities, but when you see projects like this condo complex that managed to install chargers for just $405 per parking spot, all of a sudden it becomes a no-brainer not to have EV charging.

But the fact is, there just aren’t enough apartment complexes out there which have EV charging. So if Forth’s Charge At Home program can help residents or landlords with that, it can go a long way towards solving the only real problem with EVs. Click here to check it out.

This Maryland county will get its power from a solar farm on landfill

Baltimore County, Maryland, just brought its first large-scale ground-mounted solar farm online, and it sits on what used to be the Parkton Landfill. The 213-acre site, once a symbol of waste, is now generating clean power that will cut costs, slash emissions, and turn an underused piece of land into a long-term energy asset.

Located north of Baltimore City, Baltimore County is one of Maryland’s largest and most populous counties, and its push toward renewables has major implications for the state’s climate and energy goals.

County Executive Kathy Klausmeier called the project a clear example of innovation meeting sustainability: “We are cutting costs for taxpayers and making investments that benefit our communities for decades.”

The new solar farm will provide around 11% of the Maryland county government’s annual electricity, producing roughly 8.2 million kilowatt-hours (kWh) in its first year. That’s the equivalent of avoiding greenhouse gas emissions from burning over 620,000 gallons of gasoline, powering more than 1,150 homes for a year, or driving 14 million fewer miles in gas cars, according to the EPA.

The 7 MW system includes four large solar arrays of 15,000 ground-mounted photovoltaic panels. It’s part of a growing trend in the US to repurpose capped landfills for renewable energy, turning dormant properties into productive clean energy sites.

Through a power purchase agreement with TotalEnergies, which owns and operates the system, Baltimore County will lock in reduced electricity rates for 25 years, with options to extend the contract for up to 33 years. That long-term deal protects taxpayers from future electricity price hikes while advancing local climate goals.

“Adding another large source of solar electricity to power our County’s facilities reflects our community’s values of making smart investments that take care of the health of our community and environment,” said Greg Strella, the county’s chief sustainability officer.

TotalEnergies Managing Director Eric Potts called the project a “powerful example of transforming underutilized assets into productive resources,” pointing to the dual benefits of cutting emissions and saving money.

Baltimore County’s next landfill solar project, at Hernwood, is expected to come online by 2028. Once that system is up and running, renewables will supply about 55% of the county government’s electricity use.
