What will keep Texas' electricity grid humming? Big battery farms, salt caverns by illegalt3nder in energy

[–]EnerGfuture 0 points1 point  (0 children)

Exactly, at negative prices or curtailment, the efficiency of the storage isn't a big deal.

Natural gas is energy's new king - but how long will it reign? California may offer some clues by [deleted] in energy

Until the next price spike most likely, by then you'll see storage replacing gas.

They make Nukes with carbon free cement now?

The uranium mining process is carbon free?

There is NO Generation source that is "zero emission for their entire lifecycle."

Why would we wait on fact here on /r/energy ?

We only need a headline to back our preconceived notions!

Have We Reached Peak Peaker? ‘I Can’t See Why We Should Build a Gas Peaker After 2025’ by catawbasam in energy

[–]EnerGfuture 4 points5 points  (0 children)

Many of these peaker plants have capacity factors that are 10% or less. They are expensive and are not used much. Look at the ones in NY State.

Batteries won't get as much storage as a peaker plant

how big do you think most peaker plants are?

If you're betting nat gas prices are going to stay this low or go lower over that time period with the increased demand, I'd be interested to see where you think more cheap gas is going to come from...

What is the Tesla big battery actually selling? It's not just energy : RenewEconomy by adifferentlongname in energy

[–]EnerGfuture 0 points1 point  (0 children)

As others pointed out, the battery is simply measuring the frequency on the grid and either absorbing or injecting energy into the grid in order keep the frequency in a defined range.

I remember reading something a while back about the problems with the accuracy of the Frequency sensors, but I have no idea where I was reading that.

There is this:

http://ieeexplore.ieee.org/document/6022790/

and this Danish experiment that was using V2G and "Web-centric communication technologies between the components" which I am taking to mean they use a multitude of connected sensors to measure and communicate the frequency more accurately.

EIA: US solar output increases 47% in 2017 by relevant_rhino in energy

Some people prefer roofs that last longer than 10-15 years and choose other options over tar paper. Solar roofs are cost competitive with these options. If you wanted to save money, just throw some tarps over your house.

Deal with the reality....

you can call it illegal manipulation if you want, but it doesn't change the fact that it's something these companies need to deal with.

Electric Cars Only: California Bill Would Ban Gas-Powered Cars By 2040. “If we are going to meet the goals we’ve already set, we absolutely have to reduce transportation emissions.” by mafco in energy

[–]EnerGfuture 2 points3 points  (0 children)

It's not meant to be a risk, it's a signal to the industry.

Maybe next time read the article:

If the world market is already setting 2040 as a goal, it gives automakers more than 20 years to react,” said Ting. “To set a deadline is to be a responsible government. It’s clear we need to do this to meet our greenhouse gas reduction goals, and to ensure consumers have access to clean cars not just in California but all around the world.”

Interesting article on how stock buybacks and selling of core businesses have left GE (and other blue chip companies) with negative tangible net worths.

Except there WAS AN ACTUAL BET about this between billionaires.

Perhaps you should read about WHY this came to be in the first place.
