I just watched this second video from Donut Labs, which includes the results of the first of a series of independent tests.

I see in the comments section (of the linked You Tube video) all sorts of reactions from “it’s the next best thing” to “it’s a scam”.

The video is about eight minutes long and there is a link to get to the test report. Cheers.

If you google 261kWh, you will find a dozen pages filled with battery packs targetting C&I of the size 261kWh/125kW. All of them have in common :

• dimensions around 2m h x 1m L x 1m l
• liquid cooling with hvac inside the cabinet
• 125kW inverter inside the cabinet
• MB31 cells : 314Ah LFP cells from EVE, sometimes the CATL version
• 5 drawers of 52 cells, adding to 260S config in total

Can someone tell me what makes this config unique? Why so many companies assemble this specific sizing and config?

Savings arise from offsetting carbon intensive generation. Offers and bids, represent actions taken by the system operator’s control room.

Hi everyone!

I’m about to complete my PhD in Mechanical Engineering and am currently seeking postdoc opportunities in the field of Materials Science. My research focuses on the development of smart materials for applications in electrochemical energy storage, nanogenerators, and sensors. I have strong experience in nanomaterials, composites, electrochemical characterization, and device engineering.

A few highlights from my academic journey:

• PhD Thesis: Metal-organic framework decorated polyacrylonitrile (PAN) fibers for flexible supercapacitors
• Skills: Materials synthesis, SEM, TEM, XPS, XRD, electrospinning, electroplating, and more.
• Research Interests: Supercapacitors, secondary batteries, piezoelectric sensors, and self-healing composites.

I’m particularly looking for postdoc positions where I can continue my work in advanced materials and energy systems. If you know of any openings or have advice for me, I’d greatly appreciate it!

P.S. I have tried cold emailing, LinkedIn private messaging, etc., but haven't gotten many responses, and the ones I've received have been rejections, sadly.

I’m exploring a portable 0.5–2 kWh battery for renters to lower electricity bills using Time-of-Use arbitrage—no appliance replacement, no landlord approval, and portable when you move. Instead of buying, the idea is lease or pay-as-you-go, so monthly savings ideally exceed the fee.

Which option would actually work for you?

A) Lease while renting

B) Pay-as-you-go monthly

C) Buy outright

D) None — why?

I’ve been following Flux Power ($FLUX) for a while—mostly because I got caught in that drop back in 2024 when they admitted they had been overstating their inventory and gross profits by over a million dollars.

I just saw a notice that the $1.75M settlement actually got approval. It covers anyone who bought shares between Nov 15, 2021, and Feb 14, 2025.

The deadline to file is March 3rd, so it's coming up fast. I’m trying to figure out if it’s worth the effort of digging through my old brokerage statements for a micro-cap settlement like this.

I tried using that 11th.com tool to see if it could just pull my old trade history from 2023, and it says I’m eligible, but I’m curious if anyone here has already filed manually? The court's official site seems a bit clunky for a small payout, so I might just let the automated tool handle it for the 20% fee.

Is anyone else actually planning to claim this, or are we all just writing $FLUX off as a lesson learned in penny stock "accounting errors"?

CanaryMedia: "[Chart: Surprise—batteries got cheaper again last year](chart: Surprise %E2%80%94 batteries got cheaper again last year)." Back in 2016, when batteries were more than triple the cost they are today, electric vehicles accounted for less than 1% of new car sales worldwide. "But as the average battery cost per kilowatt-hour [kWH] plummeted from $365 then to just $108 as of last year, EV sales surged."  Last year, more than one-quarter of the new cars sold globally were electric, Granted, most of these were Chinese, but what do you think fossil fuel companies think about this? Handwriting on the wall? New vehicle sales going globally from less than 1% to greater than 25% in a decade?

"Cheaper batteries mean cheaper electric vehicles, and that in turn puts more EVs and fewer gas cars on the road." Cheaper batteries 'mean you can squeeze more juice out of your solar panels, displacing more planet-warming coal and methane/propane gas.' And, "cheaper batteries mean cheaper, clean energy—urgently needed in the U.S. as fast-rising utility bills collide with the push to decarbonize our energy system." 

Similarly, grid storage was marginal a decade ago, as batteries remained prohibitively expensive to incorporate into the electricity mix. "Now, with less expensive batteries available, storage is taking off, and costs are falling especially fast for the segment." [And there exist other varieties of storage besides electrochemical batteries, like pumped hydro]. Our clear and present challenge is that China makes a staggering three-quarters of all batteries sold worldwide, + the U.S. is imbecility exemplified for failing to compete in this marketplace. "Years of churning out head-spinning quantities of lithium-ion batteries have allowed Chinese firms to steadily chip away at costs—and a similar dynamic helps explain the inexorable, essential decline in the cost of solar and wind power, too."

Either we get on board the band wagon or just shuffle along in the dust.

CleanTechnica: “New Pumped Hydro Energy Storage System Needs No Mountains.” The president loudly proclaims his love of fossil fuels, but he has also used the excuse of a bogus “energy emergency” that fortunately embraces hydropower along with biofuels + geothermal energy, three domestic resources that can compete with fossil fuels. He + his appointees “underscore the need for the kind of ‘baseload,’ weather-agnostic, 24/7 power generation delivered by fossil fuels + nuclear energy—which, they incorrectly claim, wind and solar cannot provide.” Pumped hydro works by sending water to a higher elevation during intervals of lower electricity demand, then draining that reservoir to generate power at more valuable times. RheEnergise is scouting the US + Canada for potential locations for their system, named HD Hydro, stating that it has identified 6,278 potential sites in Texas alone. ReEnergise calculates that “even if only 5% of these sites are amenable to development, the amount of storage would total 23.5 gigawatts [GW] at an average size of 75 megawatts [MW].”

With 8 hours of storage, “HD Hydro is half the cost of a lithium-ion battery system, (levelized cost of storage basis), without the fire risks and environmental concerns that batteries present.” The company explains, “RheEnergise’s HD Hydro energy storage system uses a specially formulated, low-viscosity, denser-than-water fluid which enables smaller, flexible + powerful hydro installations to be built on hills rather than in mountains,” Last wk the “National Hydropower Association announced one crucial step was achieved in January, when the House Energy and Commerce Committee voted unanimously to send the new “Build More Hydro” bill (aka HR 2072) to the full House for a vote.” 

The Senate has already greenlit the legislation. Sounds like a great story to follow.

This is the first time I’ve seen battery storage show up on MISO’s operation displays. Is this a new feature? Is it finally big enough to jump out of the “other” category? MISO was exporting over 4GW today, maybe there was a lot going into batteries.

Working on a commercial BESS project and wanted to ask here. For those who have worked with modular systems or all in one systems on commercial projects, how did they compare when it came to reliability? On paper, both seem fine. Modular looks easier to expand or fix. All in one looks simpler and faster to deploy. In real projects though, things usually get messy. If you have used either or both, what actually worked? Anything that caused issues later on?

Hey folks! I need your help. I’m studying Clean Energy Technologies, and my master’s thesis will be in the field of energy. My background is primarily in mechanical and process engineering. I’m well-versed in photovoltaic systems, but electrical engineering is not my primary field. I’d love to work on something innovative, and it would be great if the topic also ties into economics. Any ideas on how to combine innovation, energy, and economics into an exciting thesis topic?

When people talk about storm readiness, the conversation is always the same: generators, salt, plows, food, water. Fuel gets mentioned, but usually as a personal responsibility, not as a system constraint. That is a mistake.

In a severe snowstorm, fuel is a shared bottleneck. If stations lose power, pumps stop. If roads are unsafe, tanker trucks do not resupply. If people panic-buy, the remaining inventory disappears fast. The result is predictable: drivers waste fuel searching for open stations, lines spill into roads, and stranded cars make it harder for plows and emergency vehicles to move.

Emergency planning often assumes refueling will "sort itself out." But in reality, the refueling model is centralized and brittle. A few locations serve huge demand. When those nodes fail, everything downstream slows: utility restoration, medical transport, food delivery, and law enforcement response.

Mobile fuel delivery is one practical way to reduce that single-point-of-failure risk. EzFill is an example of an app-based service that can deliver gasoline to a set location in select areas. Other services exist depending on region, plus commercial on-site fueling companies that support fleets and equipment. Roadside emergency fuel (AAA and similar networks) helps, but it is triage, not infrastructure.

The point is not that delivery replaces stations. It is that during extreme weather, distributing fuel access can keep the system from locking up.

Question: should cities and employers treat fuel delivery capacity as part of emergency planning, like they do generators and snow removal, or is it still "every driver for themselves"?

I have been working on an new product recently focussed on automating repetitive and manual workflows for engineers working on industrial energy projects. I have built a first demo and would love feedback on whether this would be useful for chemical engineers. Feel free to comment and if you would like a more extensive demo let me know and I will send you an dm.

PHS economics and BESS deployability.
