99.873%: "PJM may count nearly 99.9 MW of every 100 MW evaluated as dependable capacity...

Preliminary PJM class ratings for the same 2028/29 period recognize 96% of nuclear capacity, 93% of diesel utility/engine-based backup capacity & 67% of gas combustion turbine capacity"

When powering data centers, not all megawatts provide the same reliability value.

#FCEL's Block System received a 99.873% rating in @pjminterconnect's unit-specific ELCC assessment, highlighting its dependable capacity for on-site power.

“Patch the Planet”? Sorry, @OpenAI , I’m just patching Keith. 😉

Plain vanilla never goes out of style on https://t.co/oePOMZuXRt

⬇️But I did check for the PHP2Shell vulnerability anyway, & my website is not affected.

[OpenAI @OpenAI]

OpenAI models helped researchers—operating as part of our Patch the Planet initiative—discover critical security flaws in PHP, an open-source programming language used to run an estimated 70% of websites.

Over the past two months, we led a coalition of maintainers, researchers, and security providers to prepare fixes and protections ahead of disclosure. This duration was necessary because the fix was quite intricate and required a major change to the PHP engine. Every site using PHP can now safely upgrade their version to stay secure, in addition to applying mitigations from various security vendors.

Due to the severity of these flaws and PHP’s widespread use, we consider this bug to be one of the most impactful vulnerabilities in recent memory. It also marks a new phase, where AI can find security bugs with internet-scale impact.

This is an example of the Defender’s Window in action: to our knowledge, frontier AI was able to find this vulnerability ahead of attackers, giving defenders time to prepare.

At times when geopolitical events shape our food security and energy prices, rethinking how we produce small molecules is more important than ever. Thank you for giving me the chance to fundamentally rethink how we make small molecules and seeing just how far this idea can go.

@wind4me @ANativeAngeleno I'd like to see some commercial, real-world demo testing of this hydrogen fuel cell catalyst as the obvious next step in it's development.

↙️Clean Power Hydrogen @CleanPowerH2 update: no single root cause of 28May2026 electrolyzer explosion.
#CPH2 again ignores the root cause: detonation likelihood from producing mixed #hydrogen #oxygen gas!

#CPH2 the long awaited update.

Reads very positive but not sure how market will take it.

"The work completed to date continues to support our previous conclusion that there is no evidence that the incident originated within the proprietary membrane-free electrolyser"

We went through 1,686 🇨🇳 procurement documents and found evidence of a massive rip-and-replace campaign, targeting foreign controllers and software🧵

@Tijgernest @ChEnected @H2Tools @HydrogenSafety @CGA_Safety @NFPA @CleanHydrogenEU @chemical_ben @Charlie_Dunnill @JornTychsen @DickWinchester @kaffjamesnewtow Yes, There are many sources of H2S.

A big problem is that at concentrations slightly higher than first noticing its "rotten egg" smell, you lose your sense of smell, and then pass out and/or die as the H2S concentration continues to increase!

[Keith D. Patch @KeithDPatch]

Per AIChE @ChEnected Center for Hydrogen Safety, 19 dead from #H2 accidents in last 12mo.

I hope @H2Tools didn't use AI & include the 9+ #hydrogen sulfide #H2S deaths in the last year

2000ppm H2S = nearly instant death; H2S leaks explode💥

@Tijgernest @ChEnected @H2Tools @HydrogenSafety @CGA_Safety @NFPA @CleanHydrogenEU @chemical_ben @Charlie_Dunnill @JornTychsen @DickWinchester @kaffjamesnewtow US OSHA says 1000-2000 ppm H2S is nearly instant death, so I went with the worst case...

Many do not know that H2S reaches high concentrations in sour natural gas.

Sour natural gas wells that have been long-abandoned often develop nasty leaks in US & Canada towns/cities.
