What do you think about leaning into older technology like pumped hydro for solving our energy needs? Go to brilliant.org/Undecided to sign up for free. And also, the first 200 people will get 20% off their annual premium membership.

Seems like desert pumped Hydro would benefit from adding floating solar panels which help reduce evaporation and keeps the panels cooler.
This definitely reminded me of an article by low tech magazine where they talked about using compressed air for home energy use. It's always interesting to see what we can do with older tech to deal with modern problems
Great video Matt!
I think we need to maximise the use of the simpler solutions that you covered along with other low tech ones in order to save lithium and other materials that have to be mined and processed for more important uses. Processing all those elements requires a lot of energy and comes with a lot of environmental baggage.
Love it. The more these other technologies can play a roll the more lithium can be reserved for transportation. As you said, lithium batteries shine for short duration storage with a quick response time. Making them most useful when paired with other storage technologies.
Hey Matt! It is incredible how your videos are becoming more and more interesting as time passes by. This video is one of your best in my opinion. I left Discord. Sorry for not being around your channel anymore. You are a great guy, always answering even when people are not friendly. Still uncertain of why this channel is called "Undecided". 😆 Congrats!
Matt, your powerfully-presented presentation puns pack a pretty impressive punch, as such improving your persistently pleasing presentation is practically impossible. Your persona and presence are a plus and you’re persistently on-point. Props. applause 👏
Interesting topic and pleasant presentation. There's still a recurrent problem with units here such as at t=576 "Projected Li-ion capacity increase = 28GW/year". KW, MW and GW are units of *power*, for example the instantaneous output from a storage plant. KWh, MWh and GWh are storage *capacities*. GWh/year is an annual increase in power storage capacity. Any given storage plant needs rating in terms of three things, power eg in MW, capacity eg in MWh and storage efficiency as a %. Sorry for the nitpick!
Thank you for making this video, as storage really is a missing link in the renewable energy supply chain. It seems that many countries and regions have in recent years dramatically scaled up their renewable energy production but done nearly nothing in comparison for renewable energy storage leading to reliability and cost problems.
I absolutely love your take on pumped hydro. It seems that every time I point out on social media that niche solutions aren't the answer, I get a lot of hate. A lot of peoples have yet to figure out that viable solutions need to be scalable to industrial scales.
I'm taking my 4th Solar online class right now, and this one is called Battery-based solar (PVOL203). This was a great video I will share with the class. Thanks, Matt.
Lithium Ion is great for high power, but costs a lot to store a lot of energy. Great presentation Matt. In New England I can image that we use offshore wind in combination with 35GW of Quebec hydro operated to store energy. Not a trivial problem but perhaps our future.
I would love to see an update on flow batteries. They take up a bit more space, but I was under the impression that they are reliable and far cheaper per unit of stored energy. There is even a company that makes shipping container batteries that use salt water (or something close to it) as the electrolyte.
personally I am a fan of the iron/salt water batteries in combination with graphene capacitors. It's simple, elegant and can work pretty much everywhere. and the materials are both cheap and abundant. graphene capacitors are still struggling to be mass produced though.
So thank you for posting this video, as I had not really thought too about these methods of producing and story energy, and so I find this to be quite interesting, and a real eye-opener too. Cheers!🥂
I also find the idea of using the sea as a pumped storage facility very interesting.
Damming of an area and drain it. Draining it below sea level (by pumping) gives the same energy potential as filling above sea level, but is far less risky, because a dam failure refills the emptied area, instead of causing a massive wave.
Grand Coulee Dam is looking to do exactly that with Banks Lake, next to it. They have been doing it, to a degree for years, but they're looking at putting in a couple new big tunnels specifically for generation. Fascinating stuff, several billions in upgrades lately and still working on it. Keep up the good work, Matt! You rock.
94% - that's an amazing figure. They used to run whole railroads that way. In Mexico starting in Cordoba and running up a big slope through Maltrata. I'm estimating about 50 miles. It was implemented in the 1920s and was gone by the time they introduced the longer, heavily tunnel encumbered alignment in use now about 1985. Now you would just build an enormously long, straight tunnel under the old line.
What a terrific analysis and comparison of the three most well-understood electricity system energy storage technologies. The efficiency of your analysis of these technologies is likely about as close to 100 percent as anyone can manage. Thanks.
I must say, your channel is awesome.. I wish you could do more content on other issues.. I know one man can only do so much... I for one thank you for your time and efforts...
