Rivian set to debut energy storage project using ‘second life’ batteries from vehicles

Published

on

Rivian Automotive and the Honnold Foundation are working together in an initiative that is set to use the electric truck maker’s “second-life” batteries as stationary energy storage units in a microgrid project at Adjuntas, Puerto Rico. This marks a huge step for Rivian, which is planning on expanding its reach beyond the manufacture of all-electric luxury adventure vehicles.

Rivian will be utilizing 135 kWh battery packs from its development vehicles for the upcoming energy storage project, which is expected to launch in 2020. The company has designed its battery packs and modules in such a way that they can be easily transitioned from vehicle energy storage to stationary energy storage at the end of their vehicle life. The Rivian CEO described the concept in a press release.

“Second-life batteries are a big enabler to accelerating widespread adoption of renewable energy, and it’s exciting to envision this system contributing importantly to a community. This project allows us to model a customized energy storage solution that takes into account space constraints, disaster resiliency, and energy independence,” Scaringe said.

Using older batteries for energy storage is a clever way for Rivian to recycle the cells it uses for its all-electric trucks. While batteries at the end of their vehicle life will likely show some wear compared to those used in new EVs, they could still function well as stationary energy storage units. After all, optimal batteries for electric trucks require a lot of power, but those energy storage units could make do with much less (propelling the R1T from 0-60 mph, for example, takes a lot of power, but turning on the lights in a household does not require as much).

Rivian and the Honnold Foundation selected Adjuntas, Puerto Rico as the site of their microgrid project partly due to the town being in need of help. Adjuntas was struck by Hurricane Maria in 2017, and the community has been struggling with power since. If successful, Rivian and Honnold’s microgrid initiative could help many of the businesses located near the town’s main square. Residents could also have backup power in the event that power shortages happen.

DENVER, June 13, 2019 /PRNewswire/ — On June 15, electric adventure vehicle maker Rivian is announcing a project to use its second-life batteries in a solar microgrid initiative with the Honnold Foundation. The goal: to support energy independence and adoption of renewable power generation. The project, in the town of Adjuntas, Puerto Rico, marks Rivian’s first steps in its broad plan to utilize second-life batteries for a wide variety of applications.

Rivian CEO RJ Scaringe and elite climber Alex Honnold will discuss the project in Denver, Colorado on June 15 at 6PM MT. The conversation will be moderated by endurance athlete and podcaster Rich Roll. The livestream can be found here: https://www.youtube.com/c/RivianOfficial/live

Rivian has designed its pack, module, and battery management system to seamlessly transition from vehicle energy storage to stationary energy storage at the end of their vehicle life. The battery module’s thin design enables second-life applications that are space-efficient and customizable, important for environments with existing infrastructure.

“Second-life batteries are a big enabler to accelerating widespread adoption of renewable energy, and it’s exciting to envision this system contributing importantly to a community. This project allows us to model a customized energy storage solution that takes into account space constraints, disaster resiliency and energy independence,” said Scaringe.

Adjuntas is a city of 20,000 in midwestern Puerto Rico. It was severely impacted by Hurricane Maria in 2017, and with climate change increasing the frequency and severity of storms, Adjuntas NGO Casa Pueblo has sought to collaborate on rugged, affordable sources of community power.

The Honnold Foundation and Rivian battery engineers visited Casa Pueblo earlier in 2019 to meet with community leaders and together are designing a site-specific system that will power many of the businesses located in the Adjuntas town square. In power loss scenarios, the downtown solar microgrid will allow Adjuntas residents access to electricity for core businesses. By offsetting day-to-day electric bills, the system also brings down high commercial energy costs, which in Puerto Rico are twice the national average.

The system is expected to launch in 2020.

Tesla Optimus gets its latest job, and it’s not in the company’s factories

Tesla Optimus was spotted in its latest job placement, not at any of the company’s manufacturing or production facilities.

Optimus was instead spotted in New York City at Times Square, handing out Halloween candy to people:

It is not Tesla Optimus’s first gig in the service industry, as it has already secured several employment opportunities through the company’s projects. Last year, it served drinks at the company’s We, Robot day, where the Cybercab and Robovan were unveiled.

Additionally, Optimus has been helping out at the Tesla Diner in Los Angeles, serving popcorn and greeting guests.

Elon Musk reveals big plans for Tesla Optimus at the Supercharger Diner

Optimus has many capabilities, and its applications can benefit both residential and commercial users. It is designed to be an at-home assistant, helping with tedious, monotonous tasks around the house.

In a commercial setting, Optimus will be programmed to handle everything from manufacturing to other factory-type tasks, as Tesla has already been using the robot in its own factories for smaller jobs.

Optimus has been in development for several years, but Tesla is ready to turn up the heat in terms of its capabilities and engineering as it prepares to launch it to a wider audience in the coming years.

During the recent Q3 Earnings Call, Tesla CEO Elon Musk gave updates on the Optimus project, highlighting its progress and the company’s current development status.

Musk said that Tesla is “on the cusp of something really tremendous with Optimus, which I think is likely to be, has the potential to be, the biggest product of all time.” He also mentioned that Tesla is in an interesting position because not only has it established itself as one of the biggest car companies in the country, but it’s the only company that manufactures vehicles and has a monumental grasp of the importance of AI and robotics.

“I’m unaware of any robot program by Ford or GM or, you know, by U.S. car companies,” he said.

Musk added that Optimus has some pretty big responsibilities around Tesla’s factories:

“I mean, bringing Optimus to market is an incredibly difficult task, to be clear. It’s not like some walk in the park. At some point, I mean, actually, technically, Optimus can walk in the park right now. We do have Optimus robots that walk around our offices at our engineering headquarters in Palo Alto, California, basically twenty-four hours a day, seven days a week.”

Right now, it appears Tesla is having its biggest challenge with the Optimus project around the development of its hands and forearms, which Musk called “an incredible thing” on the human body:

“The human hand is an incredible thing. The more you study the human hand, the more incredible you realize it is, and why you need four fingers and a thumb, why the fingers have certain degrees of freedom, why the various muscles are of different strengths, and fingers are of different lengths. It turns out that those are all there for a reason…Making the hand and forearm, because most of the actuators, just like the human hand, the muscles that control your hand are actually primarily in your forearm. The Optimus hand and forearm are an incredibly difficult engineering challenge. I’d say it’s more difficult than the rest of the robot from an electromechanical standpoint.”

Tesla is stumped on how to engineer this Optimus part, but they’re close

Optimus is starting to get more visibility in the public, and Tesla’s move to put it smack dab in the middle of New York City is one that will certainly bring some additional eyes to its development.

Tesla analysts are expecting big things from the stock (NASDAQ: TSLA) after many firms made price target adjustments following the Q3 Earnings Call.

Last Wednesday, Tesla reported earnings with record revenue but missed EPS estimates.

It blew delivery expectations out of the water with its strongest quarter in company history, but Tesla’s future relies on the development of autonomous vehicles, robotics, and AI, which many bullish firms highlight as major strengths.

The earnings call reiterated those points, along with the belief that Tesla CEO Elon Musk should be rewarded with a newly proposed pay package that would enable him to gain $1 trillion in wealth if he comes through on a lengthy list of performance tranches.

Nine Wall Street firms made adjustments to their outlook on Tesla shares in the form of price target increases since last Wednesday’s call, all of which are indications of big expectations for the stock moving forward.

Here are the nine firms that made moves:

  • Truist – $280 to $406, reiterated Hold rating
  • Roth MKM – $395 to $404, reiterated Buy rating
  • Cantor Fitzgerald – $355 to $510, reiterated Overweight rating
  • Deutsche Bank – $435 to $440, reiterated Buy rating
  • Mizhuo – $450 to $485, reiterated Outperform rating
  • New Street Research – $465 to $520, reiterated Buy rating
  • Evercore ISI – $235 to $300, reiterated In Line rating
  • Freedom Capital Markets – $338 to $406, upgraded to Hold rating
  • China Renaissance – $349 to $380, reiterated Hold rating

The boosts in price target are largely due to Tesla’s future projects, as Roth MKM, Cantor Fitzgerald, Mizuho, New Street Research, and Evercore ISI all explicitly mention Tesla’s autonomy, robotics, and AI potential as the main factors for its price target boosts.

Cantor Fitzgerald raises Tesla PT To $510, citing Cybercab, Semi, and AI momentum

It is no surprise that many firms are adjusting their outlook on Tesla shares considerably in an effort to prepare for the company’s transition to even more of a tech company than a car company.

The issue with many analysts is that they treat the company’s vehicle deliveries as the main indicator of value.

However, Tesla has a robust energy division, which was a major contributor to the company’s strong margins and gross profit in Q3, as well as its prowess in robotics and AI.

Additionally, the company is seen as a key player in the autonomy field, especially after launching driverless rides on a Robotaxi platform in Austin and expanding a similar program in the Bay Area.

Tesla shares were up over 5 percent at 12:18 p.m. on the East Coast.

Tesla Board Chair Robyn Denholm has provided a rather compelling update on Optimus’ improving dexterity. As per the executive, the humanoid robot, which is expected to enter initial production next year, is now able to perform more deliberate tasks, such as folding laundry. 

Optimus’ dexterity

During an interview with CNBC, Denholm was asked how close Optimus was to true dexterity. Achieving human-like dexterity is a key goal for Optimus as the robot is designed to be able to perform tasks that are traditionally performed by humans. This means that Optimus should be able to move its hands in a very delicate manner. During the segment, one of CNBC’s hosts mentioned that humanoid robots today are not able to fold laundry just yet. 

Denholm responded that Tesla’s robot is now able to perform the task. “Optimus can fold laundry. I’ve been in the lab with Optimus. He can fold laundry. He can wipe the table really well. He can hand things to you. You can actually shake hands with him. The tactile nature of his hand is actually really very good,” the Tesla Board Chair stated.

Redefining robotics

The executive reiterated that Optimus is already operating in Tesla’s Palo Alto offices today. “We’re redefining what transportation is, but we’re also redefining robotics and what AI brings to robotics and how versatile the robots will be in the future,” Denholm noted.

Elon Musk has reiterated the importance of Optima’s hands during the Q3 2025 earnings call. While discussing the humanoid robot’s capabilities, Musk stated that Optimus, in its production form in the future, should be able to perform incredibly delicate tasks such as surgery. This, the CEO noted, would be pivotal in Tesla’s efforts to push the world towards sustainable abundance.

“Going beyond sustainable energy to say, sustainable abundance is the mission, where we believe with Optimus and self-driving, we can actually create a world where there is no poverty, where everyone has access to the finest medical care. Optimus will be an incredible surgeon, for example. Imagine if everyone had access to an incredible surgeon,” Musk said.
