Bloom Energy blew through billions promising cheap, green tech that falls short

Yet despite that (and even with the "if there's a silver lining [...]" caveat), ending the piece on what feels like a hopeful, positive note by the CEO founder talking about how he feels "like [he] has made a dent" just seems like a weird way to go. It seems like there's a reasonable chance that, well, he didn't. That the company hasn't built a sustainable model, and pulled otherwise productive capital, talent, and time into a venture that arguably has not in the last 12 years, and may not in the future, actually make any sort of a dent.
While based on this one article, I wouldn't be bullish on Bloom's future, I'm mostly just commenting on that decision in the writing of the piece. To my mind, it fits oddly with the rest of the structure.
Another example pops into my mind an article about a man who raped a fellow student in university.
The article was ending with "X is continuing its education at Y, and he has Z gold medals and competes for university swimming team".
This is just adding insult to injury.
I first heard of Bloom Energy seven or so years ago, when I worked in Orange County (California). I was at a company where we had a small data center on-site, with a large UPS, but with no generator backup. A Bloom Box would have been perfect as a backup power source, but at the time I looked they were just getting started.
For reference, nearby John Wayne Airport had recently built a cogeneration plant, which provided the majority of the airport's power and air conditioning needs, while still giving them the option of drawing full power from the regional utility. (See https://www.ocregister.com/2011/04/25/31-million-power-plant...) So I was very interested in exploring similar solutions for where I worked, but at a smaller scale: The building already had an emergency generator for essentials (security, emergency lighting, water, and elevators); the only thing missing coverage was the data center. But Bloom was too immature at the time.
And today, I'm lucky enough to be in an area that was not affected by PG&E's recent Public Safety Power Shutoffs (work also was not affected), but there's no guarantee that I'll be similarly lucky next time around. And my apartment is all-electric, with gas being used only to provide hot water. If heating is needed, and the power is out, them I'm stuck.
Until reading this article, I occasionally would think of Bloom Energy, and how a Bloom Box would be nice as a temporary or last-resort thing, where a generator might otherwise be installed. And I was getting annoyed at how some communities banning new natural gas installations would block that, even though PG&E is not really in a state to be trusted.
And now I read this article. And I am really annoyed. No, a Bloom Box is not the best or most efficient technology compared to, say, wind power. But when you have natural gas available, and an unstable electric grid, a Bloom Box always seemed to me to be a good backup power source. Except who knows what's going to happen to them now. Maybe someone will be able to iterate on the technology, and hopefully not become so loaded down with funding/debt that they feel the need to promise the stars.
Just an example; there are several small scale cogeneration manufacturers out there. You’re going to be stuck with a combustion engine over fuel cells, but they’re about as loud as a noisy dishwasher. Easily aired outside or in a utility closet.
If you can, rooftop solar and batteries are the way to go; you can use a heat pump water heater to efficiently and environmentally responsibly heat water (versus gas or resistive heat).
My mom lives in Paradise and she would've bought a FC generator with an ATS if such a mythical creature were affordable and lasted at least as long as a natural gas generator.
It seems like more work needs to be done to produce FC cells that last far longer even if they're physically larger. (Holy Grail / Easier said than done.)
PS: Xfinity (Comcast) goes out within the first 24 hours while cell phone service remains powered in a PSPS. In a real outage, cell phone service lasts some number of hours or a few days. There hasn't been such an event because PG&E has a large basecamp with worker housing and equipment half-way between Paradise and Chico on Skyway.
Making Methane is a promising storage technology for excess renewable energy. Bootstrapping R&D into a more efficient way of turning Methane back into electricity with a few billion dollars doesn't seem to be the worst use of money.
Since fuel cells operate electrochemically, they don't have that same limit, which means their theoretical efficiencies are often higher (and the ability to get somewhat near those efficiencies track as well). I'm not sure if they're comparing to full-size plants or not, but the differences between the two tend to be more pronounced as size and weight of generator decrease, since heavy insulation and waste re-use are more difficult, but fuel cells stay (somewhat) the same.
I certainly agree with your observation about methane being an interesting path forward for storage technology for excess renewables, though.
