Geothermal supplies just 0.4% of the world’s energy today, but it could potentially supply up to 50% of the world’s energy by 2050, according to Carlos Araque, cofounder and CEO of Quaise Energy, who made that prediction at the SOSV Climate Tech Summit 2022 last week during a panel discussion called, “Is this geothermal’s moment?”
Geothermal’s profound impact
Quaise is developing a drilling technique that was pioneered at MIT to reach the hot rock some two to 12 miles beneath the Earth’s surface. Araque was joined by Kathy Hannun, cofounder and president of US residential geothermal company Dandelion Energy. The Dandelion process uses established technology that doesn’t require such deep drilling.
Araque and Hannun went on to not only describe the biggest barriers to scaling up their businesses for the world but also what other geothermal problems they are “itching for people to solve,” according to moderator Candice Ammori, founder of The Climate Vine, which advises climate tech startups.
First, however, the two described why geothermal is so potentially impactful. In addition to being clean and global, geothermal provides a baseload energy source that’s available 24/7. It’s also “the most powerful and abundant renewable on Earth,” said Araque, “Much more so than wind, solar, nuclear, and all fossil fuels combined.”
In addition, Araque said, it’s important to weigh an energy source by its impact on externalities like the environment, land use, and mineral use:
When you look at the [problem] from this lens – how much land use per unit of energy you produce, the amount of materials necessary per unit of energy, and how much carbon dioxide you produce per unit of energy – you start realizing that geothermal comes out way, way ahead of anything else.
Barriers and solutions
To fully tap the resource, however, will be very capital and time intensive. Araque continued:
It’s very hard to achieve anything in our space with a million dollars or even $10 million.
You have to start playing at the $100 million level or even $1 billion level. This is what it costs to get [deep geothermal] developed and deployed at portfolio levels.
Further, the Quaise technology involved in deep drilling has been demonstrated in the lab but not yet in the field. And that will take time.
However, Araque said that by the end of the decade, Quaise aims to create power from a coal- or gas-fired power plant that has been converted to geothermal:
You feed in geothermal steam instead of steam from a fossil-fuel boiler. That in a brushstroke decarbonizes the power plant, and you can repeat that 10,000 times over with other plants.
The key to making deep geothermal a reality? “You leverage the oil and gas industry,” said Araque, who himself comes from fossil fuels. “I think of them as a ready-made workforce, supply chain, and regulatory framework that can push this into the world at the scale that’s required.”
Hannun noted that for Dandelion, simplifying complexity will be key to bringing down the costs associated with using geothermal for heating and cooling of residential homes:
It’s hard to advance our building stock and change all of the buildings that already exist [to geothermal because] they’re all slightly different and there’s a lot of complexity to manage. So a lot of our focus is on making geothermal [heat pumps] as simple to get into homes as it is to install a furnace or air conditioner.
Potential for entrepreneurs
Ammori ended the session by asking Hannun and Araque about remaining geothermal challenges that other entrepreneurs could tackle. Both agreed that better imaging systems to see underground are important. For deep geothermal, Araque said that there’s a need for electronics that can withstand the high temperatures associated with the resource. Hannun noted that anything related to weatherizing homes will help the geothermal heating and cooling industry.
She also stressed that for both her and Araque’s industries:
I would encourage entrepreneurs not to just look at the central core technology, but also the enabling technologies, products, or businesses around permitting, licensing, and transmission. There are [many] things in the ecosystem that need to happen to enable scale.
Araque concluded by noting that the energy transition itself is an unsolved problem:
Don’t for a second think that it’s just a matter of scaling what we have. There’s plenty of space for innovation. This is the greatest challenge of many generations, not just ours, and we need all human capital on the problem.

Wagons don’t get a lot of love Stateside, with American buyers choosing SUVs over – well, pretty much every other type of vehicle imaginable. That’s our loss, as the latest plug in hybrid versions of the Volkswagen Passat are here to prove.
The latest Passat Variant eHybrid (or, in some markets, Vario, which is what the Europeans like to call wagons) is different from the version we get in the US. Unlike the domestic version which is based on a low-cost platform specific to the US and China, the Euro-market version is built on the MQB platform that underpins VW’s flagship Arteon four-door coupe and both VW‘s and Audi’s entry-luxe SUVs.
That might seem weird, since VW has sold more than 34 million units sold worldwide and the Passat is the second top-selling Volkswagen of all time (behind the Golf and ahead of the Beetle). It’s understandable, then, that the European execs are pretty proud of their Passat.
The latest evolutionary stage of the modular transverse matrix (MQB evo)forms the highly innovative technical basis of the ninth Passat generation. Thanks to the significant economies of scale of the MQB evo, Volkswagen has again democratised numerous high-tech developments and made them available for hundreds of thousands of drivers. The two completely newly developed plug-in hybrid drives (eHybrid) are a perfect example of this. In combination with a new battery,they make all-electric ranges of around 100 km possible. This distance turns the new Passat Variant into an electric vehicle for everyday life – this is additionally ensured by short charging times as the battery can now be charged at AC charge points with 11 kW instead of the previous 3.6 kW. The Passat Variant eHybrid can even be charged with up to 50 kW at DC fast charging stations. In addition, the combination of electric drive motor and new economical turbocharged petrol engine provides overall ranges of around 1,000 km.

In case the jealous American wago-philes reading this aren’t jealous enough, Volkswagen has announced new Passat eHybrid Match and Black Editions that add nearly £5k of options for the new model year effectively for free.

“Match is better equipped than the outgoing Life, with additional features including metallic paint, VW’s IQ.Light LED matrix headlights, tinted rear windows and an ‘assistance pack’ which adds area view and emergency assist,” reports Alastair Crooks, from the UK car site AutoExpress. “The new Black Edition comes with metallic paint, 19-inch alloy wheels, a panoramic sunroof, tinted rear windows (darker than the Match’s), heated front and rear seats, a head-up display, a 15-inch central touchscreen and the same assistance pack as the Match.”
The entry-level Match replaces the previous Life trim, but costs the same £45,555 (about $60,500), while the Black Edition costs the same as the outgoing R-Line, from £48,900 (about $64,950). The order books open 14 August.

Wirtgen Vögele recently revealed the battery-powered MINI 500e and the MINI 502e electric pavers. With an electrically heated screed, a range of paving widths, and zero-emission operations, they’re paving a greener, cleaner path.
“These pavers excel on small-scale construction projects and jobs covering a small area – the type of work for which paving crews would not previously have been able to use machines,” reads the official Wirtgen Vögele copy. “Thanks to their elimination of manual labor, among other benefits, the new MINI pavers improve the efficiency and quality of asphalt paving, particularly in the construction of sidewalks and drains, as well as in tight downtown locations.”
The new Wirtgen MINI 502e (the one with wheels) and the MINI 500e (the one with crawler tracks) offer pave widths from 0.25 to 1.8 m, feature a battery-electric drive outputting 22.8 kW (30 hp), and your choice of either a 15 kWh or 22 kWh 48V li-ion battery – good enough battery capacity for up to 16 hours of continuing paving. Both versions can be fully charged on a conventional 110/120 “L1” power socket in about eight hours.

At the end of the day, it doesn’t matter what the federal EV incentives are or even what the guys on your crew want to operate. What matters is that construction noise upsets Mrs. Clancik’s terrier, and she will force the town council to keep the noise down all by herself.
If your construction company wants to bid on any municipal work, that means you’re gonna have to stay quiet. Maybe even keep the smells to a minimum, too. Buying electric equipment means you can do both.

Car brands like Volvo, Mercedes-Benz, and Tesla have built up solid reputations for safety, but their ultra-safe vehicles often come with a premium price tag. The good news for car buyers looking for a deal, but still prize safety, is that there’s an all-electric Hyundai for under $40K that scores top marks on the IIHS’ toughest new safety tests.
Last Februray, the Insurance Institute for Highway Safety (IIHS) established new benchmark criteria that included stricter side-impact and moderate overlap crash safety standards, improved safety for back seat passengers, and a stronger emphasis on pedestrian detection in low light.
“We followed the tougher requirements we introduced last year with another major update to the award criteria,” explains IIHS President David Harkey. “(The 2024) winners are true standouts, offering the highest level of protection for both vehicle occupants and other vulnerable road users.”

The Insurance Institute for Highway Safety is making it harder to earn its Top Safety Pick and Top Safety Pick+ awards from 2024, challenging manufacturers to offer better protection for back seat passengers and improve their pedestrian crash avoidance systems.
We’ve covered a few of the standout performers already over the past year-plus since the new safety standards were awarded, including the Rivian R1T (the only electric pickup to earn the coveted Top Safety Pick+ award), Audi Q6 e-tron, and the Tesla Model Y … but what we haven’t written about was the fact that the Hyundai IONIQ 6 was the only electric sedan to get a Top Safety Pick+, as well.
The good news is that it’s an excellent option. The 2024 version was named Car and Driver‘s 2023 EV of the Year, and led our own Scooter Doll to ask, “is any other automaker delivering more value in high-tech EVs right now?” and Nigel Evans over at CarBuzz to write, “Comparing the Ioniq 6 to its rivals is also an interesting exercise. For example, the Tesla Model 3 RWD now costs more than $40,000, with questionable interior design and layout and no Top Safety Pick+ from the IIHS. You can’t get the Chevrolet Bolt or Bolt EUV anymore in the budget EV sector, but they also lacked fast-charging capability.”
With up to 342 miles of range and a starting MSRP of $37,850 with all trims eligible for $7,500 in Retail Bonus Cash through Labor Day plus dealer discounts (if you can get them) bringing the price down even further, there’s a nonzero chance car buyers will be able to score a 2025 Hyundai IONIQ 6 for a sub-30K transaction price. Other featured deals include 0% interest financing for up to 48 months on any 2025 IONIQ 5 models in dealer inventory for well-qualified buyers, while lease buyers able to get a new SE model for $199/mo. with $3,999 down.
