The leading construction and mining equipment manufacturer, Caterpillar (CAT), is plowing ahead with plans to advance sustainable mining. Caterpillar successfully tested its first battery electric 793 large mining truck.
Caterpillar’s large 793 electric mining truck
Caterpillar held a demonstration yesterday showcasing the abilities of its massive 793 electric mining truck while announcing a “significant investment” to convert its Tuscan, Arizona, proving grounds into a sustainable testing and demo site for future electric products.
According to Caterpillar, the demonstration was made possible through crucial mining customers participating in its Early Learners Program, such as BHP, Freeport-McMoRan, Newmont, and Rio Tinto.
Group president of Caterpillar, Denise Johnson, explained the significance of its new large electric mining truck for customers, stating:
Our global team came together to develop this battery truck at an accelerated pace to help our customers meet their sustainability commitments. This demonstration is a significant milestone, and we are excited for these trucks to get to work at customers’ sites around the world in the near future.
Caterpillar initially created the program in 2021 with a focus on advancing the development of battery electric trucks for sustainable mining operations while offering mining customers an opportunity to test and validate them.

Caterpillar’s EV mining truck demonstration results
During the demo, Caterpillar’s large 793 electric mining truck plowed through a 4.3-mile (7 km) course. With the EV truck fully loaded to its rated capacity, it achieved a top speed of 37.3 mph (60 km/h) and traveled 0.62 miles (1 km) up a 10% grade at 7.5 mph.
In addition, the large Caterpillar EV mining truck completed a 0.62-mile (1 km) test on a 10% downhill grade. Perhaps, most importantly, the e-mining truck was able to capture the energy normally lost to heat, redirecting the energy back to the battery.
After the demo was completed, Caterpillar said the 793 truck had enough energy left to perform more tasks if needed.
To advance the progress, Caterpillar says its working to transform its Tucson, Arizona, proving ground into a functional “sustainable mine site of the future” by utilizing several renewable energy sources.
Johnson adds:
The transformation of the Tucson Proving Ground allows Caterpillar to demonstrate our energy transition commitments and serve as a stronger advisor to customers as we navigate the changes together. We know it will take an integrated, site-level solution for miners to achieve their carbon-reduction goals, and we’re here to help as they redefine the way they mine for generations to come.
As Caterpillar implements full battery electric technology into its equipment, the company says it will use clean energy sources like solar, wind, and hydrogen that will be capable of powering its facility and products.
Although Caterpillar has been utilizing electric drive for several years now (at least 2008) due to its high low-end torque, superior control, and reliability, the company is now swapping its diesel engine for a battery to further reduce emissions.
Electric drive has been used in heavy-duty equipment for some time because of these reasons. However, as battery tech advances, you can expect to see more fully electric options being used in construction, mining, etc.

Aviation startup Electra made history last month when its EL2 became the first hybrid-electric Ultra Short Take-off and Landing (uSTOL) aircraft to successfully complete helicopter-like take-offs and landings at the Watertown International Airport.
Founded to provide affordable air travel without airports, emissions, or noise, Electra’s stated goal was to build an aircraft that could deliver on the promises of eVTOL aircraft at a significantly reduced cost compared to its more drone-like competitors. In that context, the demonstration at Watertown isn’t a publicity stunt, but part of concerted effort to validate Electra’s uSTOL performance under real-world conditions at a commercial airport — exactly the kind of place that regional operators, cargo carriers, and emergency responders actually fly in and out of.
Hitting those marks now will help Electra clear a path for FAA certification and prove that the company can deliver on the $9 billion worth of promises its made (so far).
“Electra is grateful to the team at Watertown International Airport for enabling this demonstration of the EL2’s Ultra Short capabilities in an off-runway capacity,” explains Tom Carto, director of market development at Electra. “Our Ultra Short aircraft will offer the potential to increase the use of general aviation airports and expand the capacity of larger hubs by enabling takeoffs and landings on ramps and taxiways instead of runways, feeding in regional connections without adding to runway congestion. These transformative and practical capabilities will open the door to Direct Aviation and point-to-point connections in a way that will make it easier for people to get from the where they are to where they want to go.”

The EL2’s innovative “blown lift” design features eight electric motors on the plane’s wings, enabling take-off and landing in as little as 150 feet.
Electra says the final version of its aircraft will be able operate from airfields as small as 300 x 100 ft (90 x 30 m), or about one-tenth the length of a standard airport runway. That means that, even if these eSTOL aircraft don’t open up quite as many spaces for air travel as eVTOLs, do, they’ll still be extremely flexible – and more than capable of operating from the roofs of many existing buildings and parking structures.
NOTE: in response to some of the comments, I want to point out that the Electra is capable of sustained, electric-only powered flight and uses the genset for remote operations/extended range. I should have made that clearer. This is arguably more EREV than EV.

The US Department of Energy’s Loan Programs Office (LPO) closed a $1 billion loan to restart Three Mile Island Unit 1, a nuclear reactor at Three Mile Island in Londonderry Township, Pennsylvania.
The money is being loaned to Constellation Energy Generation, which is renaming the 835 megawatt (MW) Three Mile Island Unit 1 the Crane Clean Energy Center. Constellation said in September 2024 that it would restart the reactor under a power purchase agreement with Microsoft, which needs more clean power to feed its growing data-center demand.
The project is estimated to cost around $1.6 billion, and the DOE says the project will create around 600 jobs. The reactor is expected to start generating power again in 2027.
Three Mile Island Unit 1 (in the foreground in the photo above) went offline in 2019 because it could no longer compete with cheaper natural gas, but it wasn’t decommissioned. It’s capable of powering the equivalent of approximately 800,000 homes. It’s on the same site as the Unit 2 reactor (in the background in the photo above) that went into partial nuclear meltdown in 1979, and is known as the worst commercial nuclear accident in US history.

When asked about the loan’s timing, Greg Beard, senior adviser to the Loan Programs Office, told reporters on a call that it would “lower the cost of capital and make power cheaper for those PJM [Pennsylvania-New Jersey-Maryland] ratepayers.” Data centers are driving up electricity costs for consumers.

Although it may look the same, the EV version draws power from a 105.4 kWh LFP battery pack from BYD’s FinFreams, providing up to 650 km (404 miles) CLTC driving range.
It’s equipped with two electric motors, one in the front and the other in the rear, producing a combined 445 horsepower (332 kW).

The EREV version combines a 43.7 kWh battery with a 1.5T engine, delivering a pure-electric range of 220 km (137 miles) and a combined CLTC driving range of 1,220 km (758 miles).
Some of the higher trims feature Ford’s Fuyu ADAS system, developed exclusively for buyers in China with a roof-mounted LiDAR and over 30 sensors and cameras. It even features a cool “off-road logbook” that shows drivers over 20 popular routes across China.
The interior is custom-tailored for Chinese buyers with a 15.6″ central infotainment and a smaller driver display screen. It also offers a massive 70″ AR head-up display (HUD).
Unlike the Ford vehicles we’re accustomed to seeing, the electric Bronco includes a 7.5L refrigerator in the center console.
The AWD electric SUV is coming at a critical time as Ford aims to revamp its business in China. Ford is working with local partners on new technologies, designs, and powertrain ideas for global markets.
Ford’s sales in China are down by over 14% through October this year, but new electrified vehicles, including the Bronco, are expected to help turn things around. Ford’s lineup in China mainly consists of gas-powered vehicles, which have quickly fallen out of favor with buyers shifting to more advanced, more efficient, and often lower-priced domestic EVs.
