Egy vallási tébolyult véleménye a megújulókról, csak olyan vallási tébolyultaknak, akik hisznek a megújulók eljövetelében.

Last week, Chaset signed an agreement with the city of Oakland to replace a jet fuel powered peaker plant near San Francisco Bay with a 20 megawatt, 80 megawatt-hour lithium-ion battery system. The question is, what happens in Oakland after the new battery is drained of power at the end of four hours?

Chaset has some thoughts on that question and shared them with Green Tech Media. “Right now, there’s still tremendous opportunity for the 4-hour [-duration] investments, which we’re going to continue to make,” at the contract signing in Oakland. “What you’ll see is, through 2030 probably, it’s storage, 4- and 6-hour batteries, [that] gets you where you need [to be].”

A Wood Mackenzie study of four existing natural gas-powered peaker plants found that a 6-hour battery could have handled 74% of the actual peak operations in 2017. The remaining events lasted too long for batteries to handle.

The upshot is that currently available battery technology can plausibly take over much of the peaker role, GTM says, but not the bulk power function served by larger combined-cycle gas plants. At some point, clean resources will need to supply larger amounts of power on demand for an extended period of time, especially in the evenings as solar generation tapers off.

“It’s the 2030 to 2040 time frame where it’s a little bit more challenging and we don’t necessarily have the right solution identified just yet,” Chaset says. “Some would say maybe it’s pumped hydro. Those are huge investments. Yes, there’s technological innovation happening, but that’s mostly concrete and steel.”

 

Nick Chaset recognizes the changes any of these alternative strategies could bring to energy markets but feels the focus should remain on what is possible today. “My view is, let’s not make that investment yet if we don’t have to,” Chaset said. “Let’s make the investments that we know we need right now — that’s really solar plus energy storage — and let the technological ecosystem evolve a bit more to see what the winners and losers are.”

 

Lithium-ion batteries may not be the perfect solution but they are the best option available at the moment. They are allowing utility companies to consider shutting thermal generating stations and not build new ones. That’s an epic win for the world and buying us time to get to what’s next.

Ez a vallási fanatikus nagyon jól leírta a megújulókban való hit lényegét. 

Nem kell most itt helyben mindent, a világ összes problémáját megoldani fejben ahhoz, hogy haladjunk, hogy a következő lehetséges lépést megtegyük! 

Meg kell lépni ami lehetséges, az okoskodást pedig rá kell hagyni az okoskodókra!
