Texas power issues. Windfarms getting iced up. 67

[Alistair_Heaton]

That's a lot of capacity that's been lost. Must admit being Aberdonian we always associate Texas with hot and humid... Not snow storms.

Second paper. This is by fuel cell guys. Even they are not sold on it.

The problem with sloppy work is that the supply FAR EXCEEDS the demand

its was only a suggestion hadn't looked at it really.

The thermal cycles is what the ripple receivers are in the mix for in Germany.

Basically when the coal fired stations in Germany hit there min out put they start reducing solar and wind via the ripple system.

So when the plants hit min output the broadcast is sent out and all the domestic solar drops output to 80% and if demand further drops it happens again down to 60% etc etc. The inverter battery systems allow them to charge using the capacity they can't feed in and provide local consumption. Goes dark solar they broadcast out an increase or a release to 100% as the light drops off by itself injection drops coal start ramping up again. Batteries take care of local usage to cover while the coal power ramps up. By the time the batteries run out the coal is back up to normal operating temps.

The little people still produce there own and get to inject a bit and charge there batteries, Coal plants don't go cold and also cover what fuel is used and operating costs. And everyone is happy.

But it wouldn't work I suspect in Texas because the big boys would lobby to screw the little people over to maximise their profits and nobody would be happy.

Texas power grid CEO fired after deadly February blackouts

Bill Magness was given a two-month termination notice by ERCOT's board in a meeting Wednesday night.

I wonder what he has in his share portfolio...

And he will start work the next day if he so wishes with one of the big boys. Or maybe a few of them doing one day a month and actually earn more than he does just now.

 

[SnTMan]

Yeah, these people never just go away...

The problem with sloppy work is that the supply FAR EXCEEDS the demand

I think the definition requires a couple of addenda... 'the minimum required inputs' have to be environmentally friendly, and the output has to include the 'cradle to grave' life history... then your definition is better...

Rather than think climate change and the corona virus as science, think of it as the wrath of God. Feel any better?

dik, your definition does, mine does not

News...
"AUSTIN, TEXAS -- Texas' power grid manager was fired Wednesday amid growing calls for his ouster following February's deadly blackouts that left millions of people without electricity and heat for days in subfreezing temperatures.

Bill Magness, CEO of the Electric Reliability Council of Texas, becomes the second senior official to depart in the wake of the one of the worst blackouts in U.S. history. The state's top utility regulator resigned Monday.

Magness was given a two-month termination notice by ERCOT's board in a meeting Wednesday night. The move came as the grid operator is now under investigation by the House Oversight Committee."

SntMan,

The hydrogen production is getting pushed because the electrical grid has been built up to meet some arbitrary green energy goal. Round trip on hydrogen producing windmills to electricity is around 30%.

 

[1503-44]

Sounds about right. Fortunately a high efficiency is not required to get the job done.

 

[RedSnake]

Maybe excess power during the summer/blowing a gale gets pumped into producing hydrogen which is then burned when the wind drops or the sun is hiding?

One thing that stil needs electricity and maybe more so in the summer then in the winter is electrical cars.
Of course you cant save the energi in the car to the winter, but other sources that hade to been used instead can be saved.
Saving hydropower or or even pumping water back in hydro storages is one way.

[SnTMan]

dik, well, yeah exactly, nobody knows exactly what means GREEN. Some seem to think it means shutting down western economies while building a coal plant a week in, ummm, somewhere in Asia.

Fischstabchen, yeah I know why, but from my reading (primarily the two linked papers), I am underwhelmed

The problem has to be solved... not relocated.

Storing or transporting large amounts of hydrogen is problematic, and there are alternative system configurations that either burn the H2 in a gas turbine at the same location the H2 is generated and stored ( short term), or convert the H2 to ammonia NH3, store it , then burn the NH3 in a gas turbine modified to combust NH3.

If H2 is injected in the natural gas pipeline system it affects the "merchantability" of the gas as it changes its wobbe index and the combustor's flame flicker frequency and emission characteristics.

IMO, if the "climate change" narrative is modified to accept the upcoming "maunder minimum" and allows continuing use of methane , then the H2 can be converted to CH4 methane and directly injected into the existing gas pipeline system, as it only slightly affects the wobbe index and flame characteristics. I believe this conversion H2==> CH4 can be accomplished with an iron catalyst and carbon particle fluidized reactor.
