This graph shows that most of the power failures in Texas were caused by gas-fired generators failing. Wind power was at the normal level for this time of year. It did fall on Feb. 17, but it soon recovered.

For the past 20 years, naysayers have decried the limitations of wind and solar power and have simply moved the goalposts each time those supposed limitations have been exceeded.
Agreed, but they do have one valid point, which is that wind and solar cannot be generated on demand. To increase them above a certain percent, you need storage such as pumped hydro, batteries or hydrogen generation with fuel cells.
Pumped Electricity.

The same holds for nuclear. Ramp up time one day! Only gas takes 1 minute only!
Myy be people mix excess production with "on demand".

Absolutely, as well as a smarter grid with demand management. Pumped hydro is great but not very expandable at this point. Battery technology will only get better and cheaper. And lithium-ion is not necessarily the only game in town for utility-scale storage. It will be interesting to see if competing technologies can make any inroads against lithium-ion given its rapid expansion for vehicle use.

The “battolyzer”, and with Nickel and hydrogen is probably prone to have some kind of LENR phenomena in it (Don’t tell Dr. Galushkin, he will start yelling thermal runaway!). Thanks for sharing this Wyttenbach .

Exploring the Impacts of Extreme Events, Natural Gas Fuel and Other Contingencies on Resource Adequacy
Abstract
The electric power industry is shifting its generating portfolio towards variable energy resources and natural gas. As these changes are occurring, the industry needs to plan for resource adequacy that will make electric service more resilient to significant disruptions of supply whether they are the result of weather, cyber / physically attacks, fuel constraints or multi-factor events. Across each of these topics the power industry today employs planning methods that tend to understate the probability of supply disruptions affecting multiple units and their impact on consumers and the system itself.
This white paper focuses on planning for resource adequacy given a world in which supply disruptions are correlated and no longer limited to the outage of independent units and may be due to widespread or long-duration events with significant economic impacts on consumers. The paper highlights the following attributes of planning for resource adequacy in an environment of increasing numbers of extreme events:
The paper concludes with an identification of strategies that an individual utility and/or an ISO/RTO could follow based on its unique situation.

What is the chemical reaction of the powder to get hydrogen?
Navid article doesn't say so I was hoping that Alan Smith, being a specialist in exotic extraction of hydrogen, might clear it up

Well,, 95% of the article is about some new chemical idea using silicon nanopowders - which they say are currently too expensive to use. So they are using some more conventional chemistry right now- not the silicon system they are promoting. I suspect it is powdered aluminium/gallium alloy.
This is rather like showing off a revolutionary electric car and then mentioning (very briefly) that it currently has an IC engine because your electrical magic is too expensive to sell.
What is the chemical reaction of the powder
'Tekhy ' yields zilch by Google...
however 'Apollon hydrogen generator ' reveals a patent for thermal decomposition,,
the powder/reactant may be something like Alane... aluminium hydride..or NaBH3.. but these are not
manna from heaven but are rather expensive

"Aluminum hydride (AlH3 or alane) is a preferred thermal decomposition fuel. Alane undergoes a controllable thermolysis reaction when exposed to sufficient heat, thereby producing hydrogen gas and solid, environmentally begign reactant products (including metallic aluminum). Alane is advantageous because it is relatively dense and its thermal decomposition temperature is relatively low. Up to about 2 to 3 weight percent of polypropylene can be included as a binder. Other thermal decomposition fuels that may be suitable for additional embodiments include metal and/or other hydrides which undergo a thermolysis reaction when heated, without a catalyst being present."

I am curious about you asking about this, have you lost hope in the Hydrinos?
I am not sure if this has been covered or not as I did't read all 77 pages of this forum but I have done deep analysis of the so-called renewable power industry and have had many boardroom discussions about its role in the energy future. What most industry experts fail to realize is that intermittent power sources like wind and solar from a systemic viewpoint do nothing more than cannibalize existing energy infrastructure at the expense of reliability and cost. Case in point, why the huge discrepancy between what power companies pay for wind and solar power vs. what retail customers pay? Look at what happened in Texas. Wind and solar investors took the public utilities for a ride and ate away at future revenue/profits. In Texas they focused on the profit in front of their face and disincentivized grid reliability. Solar and wind should most definitely not be subsidized. On the contrary they need to be taxed to build the necessary back-up required for when the wind doesn't blow and the sun doesn't shine. The whole solar and wind industry are a wealth redistribution scheme where everybody pays. Look at Germany. More renewables, increased energy cost. Its a win-lose game. Not sustainable by any definition you use.
