The Energy Vault is a Dumb Idea, Here's Why

Gravity Energy에 대한 유튜브 영상 등의 내용을 영어 자막의 내용으로 자료화 하는 중임.

그대로 옮겨온 것이며 그냘 적어봅니다. (적다보면 공부가 될 수도 ... ...)

 

소견 :

"국가 권력과 세계 권력자들은 시민이 에너지와 경제적인 독립을 아주 싫어합니다."

so apparently the gravity battery is back in the spotlight i've seen news
articles about it pop up recently and now it's time to stop the script before
things get out of hand this will be short and sweet but if you want a more
detailed take you can check out thunderfur's video link in the description
so what is the problem with this thing in energy production especially with
renewables we have periods of energy surplus and energy deficit you need to
put surplus power somewhere so you can use it during your deficit but how do
you store all that power do you build a giant battery yes and no this is where
the gravity battery comes in in this case called energy vault the concept
itself sounds reasonable you have a bunch of cranes in the middle with
concrete blocks lying around when you have surplus energy you use it to stack
the blocks when you have an energy deficit you lower them down and spin a
generator in the process here's their promotional video where the ceo talks
about saving the world while stock music plays in the bank how to solve one of
the largest global problems facing our planet today
how to store renewable energy in both an economical and sustainable way cemex's
solution eliminated the transportation sector so we could end the world's
reliance on robert piconi the ceo of energy vault
all right so why is this incredibly stupid first off the blocks there are about 10 000 of them on this picture.

let's assume each one is about 20 cubic meters based on how big the ones were in
their promotional video that's 200 000 cubic meters of concrete producing one
cubic meter of concrete takes 0.41 tonnes of co2 to make this entire thing
you're looking at 82 000 tons of co2 emitted into the atmosphere neat there
are ways to produce bricks in an environmentally friendly way though as
they show us in their video but this would not be an option everywhere plus
they look like they would fall apart much sooner also have you heard about
this thing called wind on most of that promotional cgi the thing is next to
wind power plants places where winds are strong in that place you have a giant
six-sided crane with some very long wires and you'll be trying to stack
blocks with high precision i see now this is where the proponents of this
project would say the software software will handle it is detectable equivalent
of i have faith in jesus the energy vault also comes with a 30 to 40 year
warranty i would assume even shorter since that would be thirty to four years
of banging blocks together according to the website the thing has the capacity
for 35 megawatt hours so a single three megawatt wind turbine operating at say
25 on average for a whole day that's 18 megawatt hours now i'm no engineer but
if i understand it correctly one giant tower of concrete can almost store the
daily output of two wind turbines nice so this design clearly has a lot of
issues that need resolving so let's do it first off the wind problem how do we
stop the wind from blowing us around forget that stupid six armed crane
design and use a giant gantry crane instead it's far more stable than a
regular crane alright so we now have a stable crane but we haven't solved the
wind problem completely the wires are still affected so instead of having this
thing on the surface let's dig a hole for it there we go with this we solved
the wind problem this also solved the second problem capacity digging a huge
bit below the gantry lets you stack blocks much higher and thus store more
power how come you people never thought of this seriously why even have a
regular crane arranging things in a circular formation why not a gantry with
a square formation it's not because the circular design looks very futuristic on
the cgi right it's it's not that right the third problem is the blocks they are
subject to damage and erosion and need to be replaced eventually we could solve
this if we had a material which doesn't break or erode this is the point where
elon musk would say this is synthetic self-fixing hyper diamonds and i say
water so why don't we just fill our big hole with water put some water tanks on
the gantry and pump the water up when we have an energy surplus and let it down
through a turbine when we have a deficit come to think of it what if we just dug
a hole somewhere higher and let the water down from there that way we don't
need gantries or water tanks let's call this new invention pumped storage
hydroelectricity.

there we go we revolutionized energy storage i guess congratulations thank
