7 Ways To Store Renewable Energy | Answers With Joe

Renewable energy is growing by leaps and bounds, but in order for much of it to work, it needs to be stored during peak production and released during low production.

The future of renewables may lie in our ability to store and use the energy they generate. Here are 7 big ideas to make that a reality.

12:35 "Utility scale battery storage is going to explode in the next several years"...

Poor choice of words Joe.

[hightechredneck]

@3:00 just need to point out a small correction. Power plants do not want to overproduce not because of profits, but if they are producing more power than needed the frequency of the power starts to increase. If the frequency gets more than half a Hz off of 60 then protection systems start to engage which can shut down lines, cities, or plants.... Very bad things.

For the record I work in Electrical Transmission in a grid control center.

I often fill my cavernous bodies with gas, but I don't get more energy. Just complaints.

"You know what's a sobering thought? It's literally 2 weeks away from 2020" I enjoy this statement for purely ironic reasons.

Man, Diogenes is gonna have a field day with this

Humans are basically beaver with more teeth...Got it 😂

>> Seconding the requests for a whole separate episode on Flow Batteries plz!

4:56 That's the best damn explanation of pumped hydropower!

3:23 that was the first time I've heard anybody other than me say that. You can't imagine how good it feels to hear anything other than alarmist bs or denial.

In the voice of Paul Simon: There must be...50 ways to store your power...

[PontusEgnell]

I am an electrical engineer that have worked with several of the technologies that you mention. I have to say you did a very good job with this video, Joe! However, I think you forgot to mention the biggest energy storage we have by far: regular hydropower. Even if you can't reverse the water flow and pump the water, it is still a huge amount of energy that is stored in the large reservoirs and it's ready to be used at any time.
Obviously you need a sizable amount of hydropower that can be powered down when solar and wind powers up, otherwise you still have the problem of excess energy that can't be stored.

[GlenWooden]

Totally agree, Joe! I have been saying for years - "It's insane that we still dig stuff up and burn it for energy". Finally it is starting to change!

"Now, are there any dam questions?"

[huimoin]

That‘s why austria has so much renewable energy, we have tons of mountains and a lot of rivers

[renchesandsords]

15:14 we need to keep an "ion" this one? Nice :)

[yuut]

5:57 when you tell your dad a very bad joke and he thinks he's supposed to laugh

[elweasel]

16:19 This just a huge grandfather clock turning a genny.

[theGoogol]

"Dam It" reminded me to hit that like because I do like this channel so much.

Lithium Ion may be fine for light weight energy density solutions, but we can definitely find cheaper grid-scale energy storage solutions and I'm glad you pointed a few of these options out.
I'll add Molten Salt Batteries as an additional possibility that deserves a mention as well though.
