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.

After cutting prices on its top-selling electric vehicle by nearly $10,000 in the US, Hyundai is now bringing the savings to new markets. Hyundai is offering discounts of over $34,000 on some of its EVs overseas.
Hyundai is discounting EVs in the US and overseas
Last week, Hyundai announced it was reducing prices on the 2026 IONIQ 5 by up to $9,800 in the US. The 2026 IONIQ 5 starts at just $35,000, making it one of the most affordable EVs available alongside the Chevy Equinox EV and the Nissan LEAF.
Hyundai said the generous EV discounts reflected its “commitment to affordability” as part of its long-term strategy.
Record vehicle sales and higher output at its new EV plant in Georgia are helping reduce costs, which the company said it’s now passing on to buyers.

The massive EV discounts are starting to pile up after Hyundai cut prices in another market on Tuesday. After launching a series of special offers in Australia on Tuesday, Hyundai is discounting some of its EVs by more than $34,000.

According to TheDriven, Hyundai reduced prices on select IONIQ 5, IONIQ 6, Inster EV, and Kona Electric models by up to $34,142.
Hyundai’s most affordable electric car, the Inster (which is sadly not sold in the US), received a $3,925 price reduction, and now starts at under $40,000 for the first time.

The IONIQ 6 is heavily discounted, with up to $34,142 off the driveway price on 2023 model year inventory. Hyundai has also reduced the prices of the IONIQ 5 by nearly $10,000. As the report points out, the savings are based on the driveway prices in NSW, which are available nationally.

Although Hyundai’s price cuts in the US were in response to the $7,500 federal EV tax credit expiring, the discounts in Australia come as demand for electric cars is at an all-time high. In September, electric vehicles accounted for 11.3% of new car sales.
In the US, Hyundai is still offering a $7,500 cash incentive for 2025 IONIQ 5 models until at least the end of October.

2025 vs 2026 Hyundai IONIQ 5 prices and range by trim
The 2025 Hyundai IONIQ 5 Standard Range starts at $42,600, while the 2026 model year is priced from just $35,000.
Although it was already one of the most affordable EVs on the market, the IONIQ 5 is hard to pass up with leases starting at just $249 per month in the US. For $10 more per month ($259), you can upgrade to the long-range SE RWD trim, which offers a range of up to 318 miles.
Since its launch in 2024, ComEd’s Beneficial Electrification (BE) Plan has supported the deployment of more than 7,200 electric vehicle charging ports and over 2,200 EVs registered to business and public sector commercial customers.
“Reducing emissions from vehicles is one of the most effective and important things we can do to improve air quality and public health,” explains Rob Anderson, President and CEO of Respiratory Health Association. “As we have seen the ending of federal funding support for this effort, ComEd’s continued commitment of transportation electrification rebates is leading the way for our shared goal of eliminating pollution and creating cleaner air for all of our communities across northern Illinois.”

Building on the $231 million investment from 2023 through 2025, the additional $168 million will assist both residential and non-residential customers transition to EVs. The company also places an emphasis on equity, with 80% of the rebates from its over 6,400 projects going to low-income business and public sector organizations serving low-income and Equity Investment Eligible Communities (EIECs).
The ComEd rebates support the goals of Illinois’ Climate and Equitable Jobs Act (CEJA), which was signed into law by Governor J.B. Pritzker in 2021 to combat climate change and promote beneficial electrification across the state. CEJA also has the goal of putting 1 million EVs on Illinois roads by 2030, and ComEd certainly has role to play there, as 90% of the 150,000 EVs registered in Illinois operate within its service territory (that’s up from 19,000 EVs in 2019).
Electrek’s Take
The EV tax credit is no more — what happens now?
While President Trump was running for re-election, he campaigned on the threat promise of canceling the $7,500 federal tax credit for EVs — a campaign promise he kept as recently as September 30th. That wasn’t the end of the road for EVs, however.
