Koloma, a U.S.-based clean fuel startup backed by Bill Gates and Jeff Bezos, says it wants to use expertise that has traditionally served the hydrocarbon industry to power a global gold rush for buried hydrogen.
It comes as buzz continues to build over the clean energy potential of geologic hydrogen, a long-overlooked resource that advocates say could play a pivotal role in the shift away from fossil fuels.
Geologic hydrogen — sometimes knownas white, gold or natural hydrogen — refers to hydrogen gas that is found in its natural form beneath Earth’s surface. It is thought to be produced by high-temperature reactions between water and iron-rich minerals.
Pete Johnson, CEO and co-founder of Koloma, told CNBC that geologic hydrogen is fundamentally an exploration and production business.
“We can use expertise and service providers that have traditionally served the oil, gas, and mining industries and quickly put them to work in driving the discovery of carbon free-resources. Leveraging and modifying what already exists will allow us to mature the industry faster,” he said.
Based in Denver, Colorado, Koloma has raised more than $305 million since it was founded just a few years ago, the company told CNBC.
The startup’s backers include U.S. venture capital firm Khosla Ventures, Amazon‘s Climate Pledge Fund, United Airlines and Breakthrough Energy Ventures, a climate and technology fund founded by Bill Gates in 2015.
In turn, Breakthrough Energy’s investors include Bridgewater Associates’ Ray Dalio, Virgin Group’s Richard Branson and Alibaba’s Jack Ma.
A potential ‘gamechanger’
A dramatic upswing in the number of companies actively searching for geologic hydrogen deposits in recent years prompted analysts at Rystad Energy to describe the pursuit as a “white gold rush.”
The consulting firm said in a research note published in March that the hype stems from hopes the previously neglected resource could be a “gamechanger” in the energy transition.
Exploratory efforts for the low-carbon energy source are currently underway in the U.S., Canada, Australia, France, Spain, Colombia, South Korea and others.
As with any exploration business and any new technology, there are still many challenges for us to overcome to unlock geologic hydrogen’s potential.

Koloma’s Johnson said that, as the industry has “picked up momentum and attention,” there’s also been a sharper focus on what he described as the “intrinsic benefits” of geologic hydrogen as a primary energy source — rather than a derivative one.
A primary energy source, such as coal, oil, wind or solar, refers to a natural energy source that has not been altered or converted.
“Geologic hydrogen should have a very low carbon impact, but also a tiny land footprint and very low water impact,” Johnson said.

Asked about the outlook for the rapidly emerging industry, Johnson said that untapped geologic hydrogen resources in the U.S. could play a significant role in the country’s decarbonization efforts.
“Russia and Ukraine were both large exporters [of] hydrogen-derived ammonia, the building block of most modern fertilizer products, and since their conflict began the world has become more aware of the importance of a domestic ammonia supply,” Johnson said.
“Geologic hydrogen resources in the U.S. will allow us to scale up our domestic ammonia production and become a net exporter, even as we dramatically drop the carbon footprint of the products,” he added.
Challenges ahead
Hydrogen has long been billed as one of many potential energy sources that could play a significant role in the energy transition, but most of it is produced using fossil fuels such as coal and natural gas through a process that generates significant greenhouse gas emissions.
It’s within this context that momentum has been growing over the potential of geologic hydrogen.
Geoffrey Ellis, a research geologist at the Energy Resources Program of the U.S. Geological Survey (USGS), told CNBC earlier this year that there could be a vast amount of naturally occurring hydrogen buried in underground reservoirs around the world.
Ellis said that just a small percentage of geologic hydrogen recovery might well be enough to supply all the projected demand for 200 years.

Not everyone’s convinced about it’s clean energy potential.
The Hydrogen Science Coalition, a group of academics, scientists and engineers seeking to bring an evidence-based view to the role of hydrogen in the energy transition, said in a blog post published on March 14 that geologic hydrogen discoveries currently supply the world with less daily energy than does a single wind turbine.
What’s more, the coalition says there are environmental concerns about the extraction process, and transportation and distribution challenges mean geologic hydrogen is not likely to be found where it is most needed.
Koloma’s Johnson said that, while that are still many roadblocks to overcome, the company is “very well capitalized, which allow us to take on these challenges the right way, thoughtfully and patiently.”
“Koloma is fortunate to have backing from diverse investors — some who are more focused on the technology and data advantages [that] Koloma is building, some who see the massive potential returns of large resource discovery, and others who are most enthusiastic about taking positions around cost advantaged low carbon derivate products that can use geologic hydrogen,” Johnson said.
“As with any exploration business and any new technology, there are still many challenges for us to overcome to unlock geologic hydrogen’s potential,” he added.
The Tesla Solar Roof tiles are still alive, but the product is on the back burner at Tesla as it failed to achieve its promises.
When launching the solar roof in 2016, CEO Elon Musk presented it as a critical product to accelerate solar power deployment, as it opens up the market to people who want to go solar but also need to replace their roof soon.
However, Tesla didn’t reach volume production of the solar roof tiles until 2020, and even then, it was at a fraction of the deployment it was aiming for.

In 2022, Electrekreported that Tesla installed solar roofs for the first time and confirmed that the Company deployed 2.5 MW of solar roofs during the second quarter of 2022, equivalent to approximately 23 roofs per week, which is far short of its goal.
Tesla shifted its focus on deploying Powerwalls and solar inverters through third-party installers.
The same thing is happening with Tesla’s solar roof tiles. The company appears to be giving up on installing them itself, but some installations are still happening with third-party certified installers.
Tesla doesn’t even give online quotes on its solar roof anymore and has people submit requests for quotes through third-party installers:
“In order to receive pricing and product information, Tesla will share your contact information with a Tesla Certified Installer.”
We are hearing less about solar roof installations lately, as Tesla has gone virtually silent on the program; however, some ongoing installations are still being carried out by third-party installers.
Weddle and Sons Roofing just posted about a new 20 kW Tesla Solar Roof installation in Topeka, Kansas:
It’s challenging to determine the exact deployment rate of the solar roof, but based on our checks with a few installers, it doesn’t appear to have increased since 2022.
Tesla-certified installers are even convincing potential buyers to opt for a regular roof with solar panels instead of a solar roof. Potential buyer Jeff Betty shared this text from an unnamed installer:
This is not entirely surprising, as the primary issue with the Tesla Solar Roof tiles is their pricing. Tesla aimed for the solution to be competitive with higher-end roofing options, but it remains expensive and much less affordable than many durable roof options, plus solar panels.
Electrek’s Take
In short, the Tesla Solar Roof is still alive, but it’s nowhere near the revolutionary product Tesla claimed it would be.
Instead, it has become a very niche higher-end roofing product that Tesla deploys in very low volume through third-party installers.
It’s not in any way a significant part of Tesla’s energy business, which is now almost entirely Megapacks and Powerwalls.
While Tesla’s solar roof is not for everyone, now is a great time to go solar with rooftop solar panels.

For the Valen Rev+, Retrospec managed to get the best out of that iconic moto-style scrambler spirit and put it into a comfortably handling fat tire e-bike while also keeping the performance bits that make it fun, and the best part is it comes at a reasonable price of just under $1,800
Aside from the looks and price this bike has a unique fun factor that comes from a combination of a few key components here.
One is the 20 by 4.0 inch Fat MTB tires with puncture protection and reflective sidewalls. Aside from these tires offering an extra layer of protection and suspension, Retrospec’s decision to offer wide tires also gives way more stability than a typical bike tire, which makes going through ruts, mud, or sand pretty effortless.
The second key component is the front suspension, which is fully adjustable and has 100mm of travel. Combined with the extra suspension from the fat tires, as mentioned earlier, this makes otherwise challenging terrain turn into fun detours that you’ll likely go out of your way to use.

The third component is the 750w rear hub motor, which gives the bike a 28 mph assisted top speed. Combined with the secure handling and added front suspension, the Valen Rev+ is the kind of bike you want to plan an adventure with. Whether that’s a dirt road shortcut on your commute or a day to the beach, the comfortable long seat makes it hard to say no to a trip with the Valen Rev+
On the practical side, Retrospec put some significant thought into the design and build of this bike to ensure that riders are cared for with those often less thought of yet still essential features. Starting with the battery, the fully integrated 720Wh battery uses LG 21700 cells for a total of 68 miles of range when fully charged. In addition, the battery is lockable and easily removable for both on- and off-bike battery charging. It’s also seamlessly integrated into the bike’s frame, making for a clean look.
For safety, Retrospec added Tektro hydraulic disc brakes with e-bike-specific rotors, which is an important upgrade, considering an improved rotor typically allows for better heat dissipation and better overall performance. There are also Integrated front and rear lights with 100 Lux illumination for the front. Safety aside, the design here for the front light looks amazing.
For the less thought-of yet essential features, Retrospec included an easy-change rear wheel removal system that uses braze-ons located at the lower part of the bike, so there’s no need to remove zip ties. Unlike other e-bikes, the Valen Rev+ kept it simple with the same axel nut for both the front and rear which means fewer tools, but what makes the process itself a lot easier is not having to wrestle the chain when re-installing the wheel thanks to the chain hanger.
One of the great feelings of the Retrospec Valen Rev+ e-bike is how simple yet stylish it is; the display is a center-mounted color display with controls on the left-hand side of the handlebars. The control panel has only three buttons, so it’s as simple as it gets. With the up or down control, you can change through 6 levels of pedal assist, but if you’re looking for more control, you can also use the controls on the right side of the handlebars to cycle through the eight speeds on the Shimano Altus derailleur.
For how comfortable the moto-inspired Valen Rev+ is, it also feels great to pedal on in case you’re looking for more exercise and want to opt for the pedal assist rather than the throttle only. Unlike other e-bikes on the market, Retrospec’s Rev+ makes riding very approachable. For those who are newer to riding, that long seat and wide tires add a level of stability, making the overall learning experience much more enjoyable. With how comfortable the bike rides, it might make you think more about leaving the car at home more often and opting for the bike paths.
For those looking to get as much fun as possible out of an e-bike aside from the fat tires and front suspension, Retrospec’s BMX style handlebars offer excellent geometry and height that gives you much more control over the bike in case you wanna stand up and tackle some of the more challenging trails. In addition, if you’re looking to forget pedaling altogether, you could even choose to get the optional footpeg accessories, which, combined with the BMX-styled handlebars, will make the bike much more functional for off-road riding.
Overall, Retrospec seems to have put a lot of effort into bringing that scrambler moto spirit into a comfortable bike with loads of features that other manufacturers haven’t quite nailed down. From the easy rear wheel removal to the BMX-styled handlebars and comfortable long seat, it’s a very approachable and easy-to-maintain e-bike that can still rip on trails for those who want to tackle more of that tough off-road terrain.

I’ll cut right to the chase. The new Model Y rival from Mazda is coming for the Y’s old sales crown with a starkly elegant 26.45-inch 5K ultra-wide display with dual screens and (get this) a massive 100″ (!) augmented reality heads-up display (AR-HUD) that projects key driving information onto the windshield, alerting the driver of pedestrians, speed limits, etc.
You can check it out for yourself, below.
Mazda EZ-60 interior revealed
Via Planet Car News.
As you can see, the interior largely eschews buttons, knobs, or physical interfaces of any kind in favor of touchscreens. Those screens enable EZ-60 drivers and passengers to control and adjust a 23-speaker, 7.1.4-channel Dolby Atmos audio system, while a separate touchscreen in the rear allows drivers passengers to adjust climate and entertainment settings for themselves.

Other interior features include super-slick digital wing mirror displays (the exterior “side mirrors” are aerodynamic cameras), and fully twenty kid- and family-friendly storage compartments sprinkled liberally throughout the vehicle. A relatively small 350-liter (12.3 cu ft) rear trunk expands to 2,036 liters (71.9 cu ft) with the seats folded flat. A 126-liter frunk (4.4 cu ft, or about the size of the mini fridge in your college dorm) adds extra practicality.
The electric Mazda SUV itself is built on the Changan EPA1 platform, and is believed to be powered by an 80 kWh battery good for 295 miles of WLTP range, and a 93 kW charging speed that can take the EZ-60 from 30 to 80% charge in a little over 30 mins.
Following the crossover’s Chinese launch – officially slated for April 23rd. Changan Mazda plans to release the EZ-60 in overseas markets under the Mazda CX-6e nameplate.
Electrek’s Take

Mazda is on a hot streak right now – and not just in China, but in the US as well. The brand’s near-premium positioning is perfect, targeting middle class buyers who are willing to pay a premium to drive a vehicle with better fit and finish than the Ford, Chevy, and Stellantis offerings – but not enough of a premium to justify a move into Acura/Volvo territory. And, frankly, no one in the industry is doing paint as well as Mazda right now. Not until you start doubling the Mazda’s MSRPs, anyway.
