ESS is a manufacturer of iron flow batteries in the state of Oregon. At the present time, lithium-ion batteries account for about 85% of grid-scale energy storage. That technology is time-tested and reliable. Prices continue to fall, but lithium-ion batteries have some issues.
They use materials like lithium, cobalt, manganese, aluminum, and nickel that can be expensive, especially if they are in short supply. They can also catch fire and begin to degrade after thousands of charge/discharge cycles. But the biggest issue with lithium-ion batteries is they can only put stored electricity back into the grid for 2 to 4 hours.
Iron flow batteries use three of the most abundant elements on Earth — iron, salt, and water. They consist of two storage tanks with a membrane between them. The membrane allows electrons to flow back and forth between the tanks while keeping the liquids separate.
If that sounds easy, it’s not. Getting the right mix of iron, salt, and water is critical, and creating a membrane that lasts a long time is no easy thing. But ESS has products ready to go and has just signed a deal with SB Energy, a division of SoftBank, to provide 2 gigawatt-hours (GWh) of its iron flow batteries between now and 2026. The first of the batteries will be deployed at a solar power plant in Davis, California this month.
In a press release, Rich Hossfeld of SB Energy says, “ESS’s unique ability to manufacture and ship batteries using iron, salt, and water is a game-changer, enabling SB Energy to offer our customers safe, sustainable and low-cost energy storage today. Long duration storage is absolutely critical to providing flexible, affordable renewable energy at scale and aligns perfectly with the Biden administration’s ambitious clean energy initiatives. SB Energy is excited to continue its partnership with ESS and deploy the company’s domestically manufactured batteries into the vast and rapidly growing market for energy storage.”
Eric Dresselhuys, CEO of ESS CEO, agrees. “This agreement exemplifies the accelerating demand for long-duration energy storage and reinforces our strong partnership with SB Energy to supply safe and sustainable technology built in the US. The energy transition will require massive amounts of storage capacity in the coming years and we are focused on scaling up our manufacturing capacity to help meet that demand. We are fortunate to have such great partners as SB Energy and Breakthrough Energy Ventures and look forward to a long and expanding partnership.”
Dresselhuys adds, “This deal is really the culmination of years of work to show that there’s a better mousetrap out there that solves more problems and is better for where the grid is going. Once people see that we’ve been vetted and tested and approved by partners like SB, that provides a lot of confidence.”

ESS claims its flow batteries last for more than 20,000 charge/discharge cycles and can provide energy for up to 12 hours. In addition, they have a life expectancy of 25 years and are easily recyclable when their useful life is over. The company says it uses the same electrolyte on both the negative and positive sides of the equation,which eliminates the cross-contamination and degradation that shortens the life of other flow batteries.
“Our patented electrode design and control system, coupled with our simple, yet elegant electrochemistry, allows you to operate longer, at higher efficiency and deeper discharge levels. Unlike typical batteries packaged as fixed cells or modules, a flow battery has significantly more energy storage capacity, which gives the user the flexibility to align both the power and amount of electricity stored precisely to a project’s requirements today and for the future.”
In addition to the deal with SB Energy, ESS has also been tapped by Enel to supply 17 of its shipping container-sized Energy Warehouse battery systems with a combined capacity of 8.5 megawatt-hours (MWh) to solar facilities in Spain.
Time-shifting is the operative concept when it comes to energy storage. Some people like to play to the grandstand and suggest smugly that the wind doesn’t always blow and the sun doesn’t always shine, and that’s why we need to keep thermal and nuclear generating plants functioning. But that blather misses the point.
As MIT noted in 2011,”The sunlight that reaches Earth every day dwarfs all the planet’s other energy sources. This solar energy is clearly sufficient in scale to meet all of mankind’s energy needs — if it can be harnessed and stored in a cost-effective way.” It says some 173,000 terawatts of solar energy strike the Earth every day — 10,000 times more energy than necessary to meet the energy needs of the entire human race. And it’s free, people! All we need to do is figure out how to harvest it, store it, and distribute it. That’s where time-shifting comes in. Generate it now, store, and use it later when the sun is over the horizon.
No one is suggesting the ESS iron flow batteries are the only solution to energy storage, but at a projected cost of around $25 per kilowatt-hour, they clearly should be part of the mix of available energy storage technologies.
However, Tesla has since removed Nissan from its list of automakers with access and switched the Japanese automaker back to the “coming soon” list.
Nissan confirmed to Electrek that access is not currently available, but it will be available by the end of the year.
It sounds like a miscommunication on Tesla’s side. We hear that it should be coming soon.
Elon Musk fired Tesla’s entire charging team – seemingly to make an example of its then-head of charging, Rebecca Tinucci, who reportedly disagreed with Musk about making further layoffs following another layoff wave.
Instead of just firing her, Musk decided to fire the entire team and then sent an email to other Tesla managers using the charging team situation as a warning.
Tesla has since had to rehire several former members of its charging team to rebuild the department.
This is believed to have slowed down the opening of the Supercharger network to other automakers in North America. We were told that communications with Tesla’s charging team were difficult to non-existent for those automakers for weeks earlier this year.
Europe’s “green dream” Northvolt has filed for bankruptcy protection in the US after a rescue package failed to go through, leaving the battery maker with just one week’s worth of cash in the account. Cofounder and CEO Peter Carlsson, who spearheaded a costly expansion, has also quit.
The Swedish-owned battery maker filed for Chapter 11 in the Southern District of Texas, reports Bloomberg, with $5.8 billion debt. CEO Peter Carlsson, Telsa’s former chief products officer, stepped down from his role as CEO after the filing, but will remain onboard as advisor and director.
According to a statement, Northvolt said that its main factory will maintain business as usual during the reorganization, as the company now has a buffer from creditors, giving it time to restructure the balance sheet. However, the company said that this will not impact its business in Germany, and through the court process, Northvolt now has access to about $145 million in cash collateral. An additional $100 million in debtor-in-possession financing will be added to the pot via one of its customers, the report said.
The company still has a $7 billion project in place in Quebec – a new campus that is set to include a cell production plant, battery recycling, and cathode active-material production facilities – and the bankruptcy won’t affect those plans, the company said on its website. “Northvolt Germany and Northvolt North America, subsidiaries of Northvolt AB with projects in Germany and Canada, are financed separately and will continue to operate as usual outside of the Chapter 11 process as key parts of Northvolt’s strategic positioning.”
The plant is expected to have capacity to produce 30 GWh of battery cell every year, with an expansion set to double that output, making it enough to power 1 million EVs. The Canadian government is putting $1.334 billion CND toward the project, with Quebec chipping in another $1.37 billion CND.
Northvolt has hit hard times in recent months, once thought of as Europe’s best shot to homegrown EVs and the makers of “the world’s greenest battery.” Enthusiasm mounted as the company opened the doors to its first plant in Sweden, in the small town of Skelleftea near the Arctic Circle, in 2021. Billions of dollars have been invested into the company, and Volvo, VW, and BMW rushed to place future orders.
All of this enthusiasm has been fueled by a vision to cut dependency on China by creating greener EV batteries using 100 percent recycled nickel, manganese, and cobalt. Plans were put in place to build factories in Gothenburg, in southern Sweden, and Poland, Germany, and Canada, all backed by huge government subsidies. Back in January, the company raised an additional $5 billion, firmly locking in its position as one of Europe’s best-funded startups and recipient of the largest-ever green loan in the EU.
But then things started going south, with Northvolt’s production problems and massive delays forcing BMW to cancel its €2 billion battery cell order with the company. This past May, Northvolt also announced that it pushing back its plans for an IPO until next year. The interim report that followed revealed the dire state of its finances and how far its production had fallen short of goals, with Carlsson admitting he had been “too aggressive” with the company’s expansion plan.
Since Northvolt has put in place a series of changes to reset the company’s course, including bringing onboard a new CFO, leaving the former CFO to focus solely on expansion plans. Plus the company started making cuts, including closing down its research center, Cuberg, in San Francisco and deprioritizing secondary businesses. At the end of September, Northvolt announced that it would cut 1,600 staff from three Swedish sites and about 20 percent of its international workforce.
Last month, Volvo started proceedings to take over their joint venture with Northvolt, while Volkswagen Group’s representative to Northvolt’s board stepped down this month. Sweden, for its part, is ruling out taking a stake to save its homegrown enterprise, Bloomberg reports. Carlsson had said last month that the company needs more than $900 million to permanently shore up its finances.

Leading yard operation 3PL YMX Logistics has announced plans to deploy fully twenty (20) of Orange EV’s fully electric Class 8 terminal trucks at a number of distribution and manufacturing sites across North America.
As the shipping and logistics industries increasingly move to embrace electrification, yard operations have proven to be an almost ideal use case for EVs, enabling companies like Orange EV, which specialize in yard hostlers or terminal tractors, to drive real, impactful change. To that end, companies like YMX are partnering with Orange EV.
“This relationship between YMX and Orange EV is a significant step forward in transforming yard operations across North America,” said Matt Yearling, CEO of YMX Logistics. “Besides the initial benefits of reduction in emissions and carbon footprint, our customers are also seeing improvements in the overall operational efficiency and seeking to expand. Our team members have also been sharing positive feedback about their new equipment and highlighting the positive impact on their health and day-to-day activities.”
This Orange looks good in blue
One of the most interesting aspects of this story – beyond the Orange EV HUSK-e XP’s almost unbelievable 180,000 lb. GCWR spec. – is that this isn’t a story about California’s ports, which mandate EVs. Instead, YMX is truly deploying these trucks throughout the country, with at least four currently in Chicago (and more on the way).
“Our collaboration with YMX Logistics represents a powerful stride in delivering sustainable yard solutions at scale for enterprise customers,” explains Wayne Mathisen, CEO of Orange EV. “With rising demand for electric yard trucks, our joint efforts ensure that more companies can access the environmental, financial, and operational benefits of electrification … this is a win for the planet, the workforce, and the bottom line of these organizations.”
We interviewed Orange EV founder Kurt Neutgens on The Heavy Equipment Podcast a few months back, but if you’re not familiar with these purpose-built trucks, it’s worth a listen.
