Almost five months after SpaceX began the process of filling and testing the first custom-built propellant storage system for Starship, the largest rocket ever built, the company has finally begun to fill the fuel half of the ‘tank farm’.

SpaceX began delivering truckloads of liquid nitrogen (LN2) to the LN2 and liquid oxygen (LOx) sections of the tank farm in mid-September 2021, well before the farm was anywhere close to completion. In about a month, SpaceX accepted ~60 LN2 deliveries – enough to partially fill one of the farm’s seven cryogenic tanks. Instead of some operational purpose, that LN2 was likely used to clean and partially proof the farm’s three LOx tanks. Just two weeks later, the orbital tank farm received its first LOx deliveries.

At the time, mere days after the basic structure of the main tank farm storage system was effectively completed, most figured that it would take SpaceX about as long to clean, proof, and begin filling the farm’s two liquid methane tanks. That would not be the case.

SpaceX installed the second of the farm’s two vertical SpaceX-built cryogenic liquid methane (LCH4) tanks in mid-October 2021. All seven cryogenic tanks had ‘sleeves’ – designed to be filled with foam insulation – installed by the end of the month, effectively completing the farm’s basic structure half a year after assembly began. However, around the same time, SpaceX also installed two horizontal tanks that were also identified as LCH4 storage – giving the overall tank farm far more fuel storage than its oxidizer (LOx) tanks could match. Starship’s Raptor engines burn about 3.55 kilograms of LOx for every 1 kilogram of LCH4.

As work on the vertical LCH4 tanks appeared to slow to a crawl, it took until December 2021 for SpaceX to begin cleaning and proofing the farm’s horizontal LCH4 tanks with liquid nitrogen. By that time, a rough unofficial narrative had been constructed to explain the lack of progress on the farm’s fuel half. Namely, in an excellent Twitter thread, CSI Starbase made a strong case that SpaceX appeared to have designed the first orbital-class Starship tank farm – a compact and pleasingly symmetric set of eight vertical storage tanks – without taking into consideration rudimentary Texas regulations for the storage of liquid natural gas and methane. By all appearances, that conclusion was correct, as the farm was visibly violating several rules – namely the requirements that all LCH4 storage be surrounded by six-foot-tall retaining walls and that all associated plumbing not be situated under power cabling.

As it exists, the LCH4 side of the vertical tank farm violates both of those rules and it’s not obvious that there is actually enough space between the two vertical methane tanks to build a retaining wall with two feet of horizontal clearance. It’s possible that the situation is more complex and that SpaceX intentionally broke those rules or was pursuing an exception to them but the end result was that those vertical LCH4 tanks have yet to be finished, let alone cleaned or proof tested. Instead, SpaceX appears to have fully refocused on horizontal tanks and most recently tore down a dirt berm beside them and began preparing foundations for at least two or three more.

Those horizontal tanks appear to store about 1000 cubic meters (~35,000 ft^3) of LCH4, while the vertical tanks would have stored about 1800 m^3. To fully replace them, SpaceX will need approximately four horizontal tanks – two more in addition to the two already installed. Thankfully, SpaceX has finally begun filling the already installed tanks while it works to expand the methane farm, beginning with three truckloads on the very first day – February 13th, 2022.

To fill the two existing tanks, which may store enough methane to fuel a stacked Starship and Super Heavy about 4/5ths of the way, SpaceX will need around 40-50 more tanker deliveries. Since last November, SpaceX has completed more than 320 liquid nitrogen and 200 liquid oxygen deliveries – equivalent to about 6700 tons (~14.8M lb) of LN2 and 4200 tons (~9.3M lb) of LOx. If SpaceX maintains that average and focuses entirely on LCH4, the two horizontal tanks could be filled to the brim before the end of February.

Having a substantial amount of LCH4 stored at the orbital tank farm will finally allow SpaceX to attempt the first major wet dress rehearsals (WDRs) and, more importantly, the first full static fires with flightworthy Super Heavy booster prototypes. Of course, a tank farm with full supplies of LOx, LCH4, LN2, and their gaseous equivalents is also a necessity for the first orbital Starship launch attempt, which has most recently slipped from a target of mid-2021 to no earlier than (NET) Q2 2022, pending regulatory approval.

Tesla Superchargers open to Lucid Air, but not without one key thing

Lucid’s full lineup of EVs is now able to use Tesla Superchargers in the United States and Canada.

Published

on

Tesla Superchargers will be open to Lucid Air vehicles starting on July 31, a move that comes nearly two years after the companies agreed to terms that would allow them to partner.

Lucid joins a long list of EV makers that have a full lineup of EVs that can utilize Tesla’s extensive Supercharger Network across the United States and parts of Canada. In all, over 32,500 Tesla Superchargers will be accessible to Lucid owners at the end of the month.

Lucid NACS adoption ‘must have been a bitter pill to swallow’: Elon Musk

All Air models, regardless of year or trim level, will gain access to the entire North American Tesla Supercharger Network. It will just need one key thing to charge: an NACS adapter.

Lucid Air sedans will require a DC NACS to CCS1 adapter in order to enable charging at the Tesla stalls. These will be priced at $220 plus tax.

Emad Dlala, Senior VP of Powertrain at Lucid, said:

“In addition to offering the longest-range electric vehicle available, Lucid is committed to offering our customers seamless and wide access to public charging. Access to the Tesla Supercharging Network for the Lucid Air is yet another major milestone.”

Charging speeds will allow Air EVs to charge at up to 50 kW, gaining up to 200 miles of range per hour.

As for the Lucid Gravity, the company’s SUV, it will not require the adapter because of its native NACS port. It gained access to the Supercharger Network in January.

Although Lucid Airs will not be able to charge at the rate of some other vehicles, they do boast some of the best range ratings in the EV industry. Having the luxury of additional charging piles to access will increase the value of the long-range ratings Lucid offers with its vehicles.

Lucid joins several other automakers that have a full lineup of EVs that have access to the Tesla Supercharger Network:

  • Ford
  • Rivian
  • General Motors (Chevrolet, GMC, Cadillac)
  • Volvo
  • Polestar
  • Nissan
  • Mercedes-Benz
  • Hyundai
  • Kia
  • Genesis
  • Honda
  • Acura
  • Aptera

Other brands, like BMW, Audi, Volkswagen, Porsche, and Subaru, are expected to gain access in the near future.

Tesla Robotaxi wins over firm that said it was ‘likely to disappoint’

Tesla Robotaxi recently won over a Wall Street firm that had recently said the platform was “likely to disappoint.”

Tesla Robotaxi recently won over a Wall Street firm that had recently said the platform was “likely to disappoint.” The ride-hailing service has been operating for about a month, and driverless rides have been offered to a small group of people that continues to expand nearly every day.

JPMorgan went to Austin to test the Tesla Robotaxi platform, and it did so just a few weeks after listing Tesla as one of its “six stocks to short” in 2025. Highlighting the loss of the EV tax credit and labeling the Robotaxi initiative as one that was “likely to disappoint,” despite Tesla’s prowess in its self-driving software.

Analyst Ryan Brinkman has been skeptical of Tesla for some time, even stating that the company’s “sky-high valuation” was not in line with other stocks in the Magnificent Seven.

However, a recent visit to Texas that was made by JPMorgan analysts proved that the Robotaxi platform, despite being in its earliest stages, was enough for them to change their tune, at least slightly. The firm gave its props to the Tesla Robotaxi platform in a note by stating it was “certainly solid and felt like a safe ride at all times.”

It’s always nice to hear skeptics report positive experiences, especially as Robotaxi continues to improve and expand.

Tesla has already expanded its geofence for the Robotaxi suite in Austin, picking a very interesting shape for its newest boundaries:

Tesla’s Robotaxi expansion wasn’t a joke, it was a warning to competitors

As Robotaxi expands, Tesla is dealing with competition from Waymo, another self-driving ride-hailing service that is operating in Austin, among other areas. After Tesla’s expansion, which brought its accessible area to a greater size than Waymo’s, it responded by doubling its geofence.

Waymo’s expansion surpassed Tesla’s size considerably, and it seems Tesla is preparing to expand its geofence in the coming weeks.

The Robotaxi platform is not yet available to the public, but Tesla has been inviting more people to try it with every passing day. Currently, the map is roughly 42 square miles, but many believe Tesla is able to broaden this by a considerable margin whenever it decides.

Tesla needs to confront these concerns as its ‘wartime CEO’ returns: Wedbush

Tesla will report earnings for Q2 tomorrow. Here’s what Wedbush expects.

Tesla (NASDAQ: TSLA) is set to report its earnings for the second quarter of 2025 tomorrow, and although Wall Street firm Wedbush is bullish as the company appears to have its “wartime CEO” back, it is looking for answers to a few concerns investors could have moving forward.

The firm’s lead analyst on Tesla, Dan Ives, has kept a bullish sentiment regarding the stock, even as Musk’s focus seemed to be more on politics and less on the company.

However, Musk has recently returned to his past attitude, which is being completely devoted and dedicated to his companies. He even said he would be sleeping in his office and working seven days a week:


Nevertheless, Ives has continued to push suggestions forward about what Tesla should do, what its potential valuation could be in the coming years with autonomy, and how it will deal with the loss of the EV tax credit.

Tesla preps to expand Robotaxi geofence once again, answering Waymo

These questions are at the forefront of what Ives suggests Tesla should confront on tomorrow’s call, he wrote in a note to investors that was released on Tuesday morning:

“Clearly, losing the EV tax credits with the recent Beltway Bill will be a headwind to Tesla and competitors in the EV landscape looking ahead, and this cash cow will become less of the story (and FCF) in 2026. We would expect some directional guidance on this topic during the conference call. Importantly, we anticipate deliveries globally to rebound in 2H led by some improvement on the key China front with the Model Y refresh a catalyst.”

Ives and Wedbush believe the autonomy could be worth $1 trillion for Tesla, especially as it continues to expand throughout Austin and eventually to other territories.

In the near term, Ives expects Tesla to continue its path of returning to growth:

“While the company has seen significant weakness in China in previous quarters given the rising competitive landscape across EVs, Tesla saw a rebound in June with sales increasing for the first time in eight months reflecting higher demand for its updated Model Y as deliveries in the region are starting to slowly turn a corner with China representing the heart and lungs of the TSLA growth story. Despite seeing more low-cost models enter the market from Chinese OEMs like BYD, Nio, Xpeng, and others, the company’s recent updates to the Model Y spurred increased demand while the accelerated production ramp-up in Shanghai for this refresh cycle reflected TSLA’s ability to meet rising demand in the marquee region. If Musk continues to lead and remain in the driver’s seat at this pace, we believe Tesla is on a path to an accelerated growth path over the coming years with deliveries expected to ramp in the back-half of 2025 following the Model Y refresh cycle.”

Tesla will report earnings tomorrow at market close. Wedbush maintained its ‘Outperform’ rating and held its $500 price target.
