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.

All the EVs you can buy with 0% financing in July, 2025

The feces-filled freight train of dystopian horrors rolls on with the passage of the Big Beautiful Bill and the untimely demise of the $7,500 federal EV tax credit. But if you’re ready to pull the trigger on a new EV this month, you’re in luck! There are plenty of great options with zero interest financing to choose from … and one with zero interest in general.

You know how we usually do these lists – some pictures, a few punchy paragraphs, and an invitation to explore local deals.

We’re doing things a little differently this month. Instead of brief write-ups, we’re highlighting the most significant 0% deal of the month (yes, that is largely opinion-based – thanks for noticing), and an “honorable mention” that doesn’t quite fit the 0% EV deal template … but might still be worth checking out.

Enough talk! Here are the deals.

Most significant new 0% offer


Tesla Powerwall 3 Cybertruck

Demand for Tesla Cybertrucks has been a long, long way from the “conservative” 250,000 per year projections Elon was making just a few years ago. Demand for the low-poly electric pickup is so dismal, in fact, that Tesla is offering 0% financing on a new Cybertruck for up to 60 months – if you’re willing to spring for the company’s Full Self Driving (Supervised) level 2 ADAS.

Not quite a 0% EV deal


Volvo-EX90-price

Don’t act surprised – my Twitter handle is VolvoJo, after all, and I’m on my fifth consecutive long-roof Swede as I type this. As such, when trying out a new format for this monthly column it made perfect sense to check out the Ironmark’s offers … and I found a good one: a new, not perfect but getting there seven-passenger EX90 at 1.99% financing plus $1,000 in “Summer Safety Bonus Cash.”

Is zero interest financing good enough to overcome the fact that most people seem to have zero interest in buying a CT these days? Is the Volvo worth a look at 1.99% with an additional $1,000 cash back? Let us know your take in the comments – but before you do that, check out the full list of 0% interest EV deals for July 2025 and click the links for additional local deals.

Lectric XP Trike2 launched as the affordable new electric trike every senior needs!

Lectric XP Trike2 launched as the affordable new electric trike every senior needs!

The new Lectric XP Trike2, just unveiled today, is the hands-down winner in the best-bang-for-your-buck category of electric trikes. And as perhaps the longest-running electric bike reviewer in the industry, I can say that with confidence. I’ve seen a lot of electric bikes in my time. I’ve spent a lot of butt-in-saddle hours on e-trikes. But I’ve never before seen a value like this roll by on three wheels.

As an able-bodied, mid-30s electric bike rider (and writer), I’ll be the first to say that electric trikes aren’t just for older folks. They’re fun e-bikes in their own right. But let’s face it – the vast majority of the market for electric three-wheelers are those who just aren’t as comfortable on two wheels due to age, accessibility, or other reasons. And so if you’re a senior or otherwise on the hunt for a fun and affordable electric trike, the Lectric XP Trike2 is probably the one you’re going to end up getting, and deservingly so!

If you don’t know Lectric eBikes, they’re the Phoenix-based e-bike company that took the US by storm in the early 2020s, quickly growing into the #1 best-selling e-bike company on the continent. They started with the ultra affordable, high-value XP line of e-bikes, and then took that same recipe to other types of e-bikes, from cargo bikes to off-roaders, and now to trikes.

The new XP Trike2 is the latest generation of their best-selling e-trike, and it’s absolutely better than ever.

Advertisement – scroll for more content

First of all though, let’s look at what stayed the same. The ultra-affordable price of $1,499 remains untouched, keeping this not only one of the best e-trikes on the market, but also the most affordable. It also keeps the low step-over height for easy mounts and dismounts, the folding frame to help riders transport it more easily, and the powerful motor that makes it a great hill climber.

Other than those features, basically everything else has received an upgrade.

First of all, we now get included suspension with a 50mm suspension fork up front. The frame has been redesigned with a new hydroformed aluminum downtube and a more stable footprint. The stem angle has been modified to make it more comfortable and allow a more upright, relaxed riding posture. A more powerful and longer-range version of the Trike2 is also available, upgrading the motor with 50% more power for even better hill climbing, as well as including a torque sensor for more responsive pedaling and a longer-range battery.

The included TFT color screen is a major upgrade over the older model, and there are even six new colors to choose from, which is a major improvement over the original XP Trike’s color option list of… one.

Base model versus the long-range upgrade

Both the base model (Lectric XP Trike2 500) and the higher-spec option (XP Trike2 750) are compelling options, but they’ll likely serve different types of riders.

Even the base model comes with a reasonably large 13 Ah (624 Wh) battery, which is already going to give most riders at least 30 miles of range (or a claimed 50 miles if using low power pedal assist and riding slower). Plus, the 500W motor is actually much more powerful, likely peaking at closer to 1,000W of actual power. That’s the “oomph” that riders will feel when climbing hills. And for many folks, that’s plenty. Plus, the $1,499 price of the XP Trike2 500 is quite attractive.

But riders who want to upgrade to the XP Trike2 750, the higher price of $1,799 does come with some nice upgrades. First of all, the higher power 750W motor will be that much better at climbing hills, helping riders up steeper inclines, or just maintaining higher speeds up the same slopes. Next, the larger 17.5 Ah (840 Wh) battery is going to give more range, to the tune of nearly 50 miles with mixed riding (or the claimed 70 miles if using lower power pedal assist and staying off the throttle). The other benefit of a bigger battery is that it simply doesn’t need to be charged as often. Even if you’re riding around at 10 mph for an hour each day, that’s a week of riding before you have to think about recharging the battery.

The last significant upgrade on the 750W model is a torque sensor, which is a more refined pedal assist sensor that results in a more natural feeling ride when pedaling. For riders who only use the throttle, there’s not much benefit to a torque sensor. But for anyone who actually wants to pedal along and get a bit of fitness in, the torque sensor means the acceleration and the riding just better mimic the natural feel of bicycle pedaling, making it more like real pedaling – albeit if you had the legs and muscle definition of a professional cyclist.

All of this is to say: The base model with 500W of power is likely sufficient for most riders, but that extra $300 does offer better hill climbing, more power, longer range, and a nicer pedaling experience – which may be important for some riders.

Lectric may have announced the XP Trike2 today, but they aren’t quite ready to ship. In something of a throwback to Lectric’s early days, the bikes are available on pre-order. Orders placed now get priority, with the 500W model shipping later this month (July 2025). The 750W models will take a bit longer, with current orders expected to ship by September.

It’s a bit of a delayed gratification situation, but if the XP Trike2 is anything like the original (and it looks to be even better), then these bikes are absolutely going to be worth the wait!

Electrek’s Take

Once again, Lectric has left all the other e-bike makers fighting over second place. My hat is off to the company – time and again they have surprised us with increasingly better e-bike generations at increasingly the same price. Each time they roll out a bike, they give us more and more, all without touching the price tag.

The XP Trike2 follows that strategy perfectly, though it definitely looks like they’re hoping the XP Trike2 750 will bring slightly fatter margins – perhaps making up for just how ridiculously affordable the XP Trike2 500 is. And while I think the lower power model will be sufficient for most people, that bigger battery, beefier motor, and nicer torque sensor do sound like a tempting upgrade.

I haven’t ridden the XP Trike2 yet, but I will be on it soon and I can’t wait to share the experience with you guys. In the meantime, let’s hear what you think about the new e-trike in the comment section below!

E-quipment highlight: Kubota mini excavator goes from diesel to EV and back

E-quipment highlight: Kubota mini excavator goes from diesel to EV and back

Japanese equipment giant Kubota brought 22 new or updated machines to the 2025 bauma expo earlier this year, but tucked away in the corners was a new retrofit kit that can help existing customers decarbonize more quickly, and more affordably.

No matter how badly a fleet may want to electrify, harsh economic realities and the greater up-front costs typically associated with battery electric remain high hurdles to overcome, but new retrofit options from major manufacturers are popping up to help lower those obstacles.

The latest equipment maker to put its name on the retrofit list is Kubota, who says its kit can be installed by a trained dealer in a single day.

That’s right! By this time tomorrow, your diesel-powered Kubota KX019 or U27-4 excavator (shown) could be fitted with an 18 or 20 kWh li-ion battery pack and electric drive motors and ready to get to work in a low-noise or low-vibration work environment where emissions are a strict no-no. Think indoor precision demolition or historic archeological excavation.

Then, if necessary, it can go right back to diesel power.

From diesel to electric and back again

If that sounds familiar, that’s because we’ve talked about a similarly flexible power solution from ZQUIP. The battery packs and diesel engines are much larger in that application, but the basic sales pitch remains the same: electric when it benefits your operation, diesel it doesn’t.

Kubota says its modular retrofit kits is a response to the increasing global demand for sustainable alternatives by focusing on making machinery that’s flexible and repairable enough to be “reusable,” and offer construction fleet managers a longer operational lifespan, superior ROI (return on investment), and lower TCO (total cost of ownership) than the competition.

Kubota’s solution also notably reduces maintenance costs and operational overheads. With no engine and associated components, servicing time and expenses are considerably reduced, saving customers both time and money. Additionally, with electricity costing far less than fossil fuels, it offers a highly economical advantage.

KUBOTA

International Rental News reports that other changes to the excavators include a more modern cab controls with a digital instrument cluster, a 60 mm wider undercarriage for more stability, and an independent travel circuit allows operators to use the boom, dipper, bucket, and auxiliary functions without an impact on tracking performance.

Kubota’s new kit, first shown at last year’s Hillhead exhibition in the UK, will officially be on sale this summer – any day now, in fact – though pricing has yet to be announced.

Electrek’s Take


If you’re wondering how it is that we’re still talking about bauma 2025 a full quarter after the show wrapped up, then I haven’t done a good enough job of explaining how positively massive the show was. Check out this Quick Charge episode (above) then let us know what you think of Kubota’s modular power kits in the comments.
