As you know guys we’ve been to many lagons we’ve been to the lagon the hmic legon and many other lagons and HPR but all of these lagons as we know they all need a j t plant to heat up the water and in this video today we are going to
Be learning in depth how a geotermal plant works and we are going to be studying the on power GE plant so we want to get right started He so here guys we ger plant in the onpow teric plant and why don’t we learn more about how it works right okay so from my understanding we have this water under theg ground that we drill 2 kilom into the ground and here we have full this water which is geothermal fluid geal
Fluid which naturally becomes Steam and then we set it um with 20 bar pressure and pressure you can it’s basically when something compact comes like here does want pressure because it’s very Compact and it can’t go away so you 20 bar pressure which is going to suck it all up because
That’s so much pressure it puts it into here and then it goes into a engine that transforms it into energy yeah exactly we drill down to these 2 km depth uh and then of course we get the steam over here which then uh goes into the power plant which generates the
Electricity we also generate hot water as you can see from this diagram over here we uh put the geothermal fluid into this tank how wait the geal fluid is it automatically steam or is it ah yeah uh we call it geothermal fluid because down below here it is under so much pressure
That it is still in liquid form but then because there’s less pressure down here no up here uh then it becomes steam all right yeah and here how do we keep it as a liquid yes exactly uh we keep it as a liquid because uh it’s still very hot
But uh there is uh not enough heat to transform it into uh water again so cool it yes exactly and then it goes into this separate uh the uh heat exchanging process over here where we are uh heating up fresh groundwater which we sent then to the uh Reika Capital Area
What is this stream here yes this stream is the geothermal fluid itself and this stream is just regular groundwater and then oh yeah and then we put the geothermal fluid back down into the Earth to uh help Nature Preserve the rable aspect and what do we learn more
About how the engine works here right over there so here comes have the engine which is called a steam turbine and basically when we get the steam it goes into here into this SM pipe goes up and then it’s going to be going into the you see these turbines here it’s made in
Such a way that it’s going to make it spin and then when you makes the turbine spin it’s going to make this a a small metal rod in the middle spin too and here over here in this um small um oval kind of shape here you have a um copper Rings
Here and with those copper rings then when it’s spinning in there it’s going to be creating a magnetic field which is well going to be um conductive to this magnet and then obviously we can use it um to transfer the electricity M exactly yeah uh these are the uh high pressure
Turbines which run at about seven bar pressure uh do you remember from the uh the B holes themselves we have about 20 bar pressure but it loses uh some pressure when it comes to the power plant so the inlet pressure is about seven bars and then at the back of the
Turbine we have uh 0.1 bar pressure all right m and then it uh condenses back into water to be either cooling down the generator itself because it uh uses a uh creates a lot of heat or to be uh reinjected into the ground again and here we have a blade well of
The engine that we see over there and can you explain to us what material this is made for and why we use this and why is it with this particular shape yes uh the material it’s L of is about 12% Chrome which helps with the corosion of
The turbine blades uh but the rest room what is corrosion room corrosion which means that it will not rust away yeah exactly so uh we do that to help with the corrosion otherwise it’s uh uh carbon sck inside but and then it will be um very how to say weak very exactly
Yes uh and the shape of it is to let the steam team come here to uh go in the other turbine plates at the back yeah kind of steer the uh steam itself uh around the turine push it and then it’ll go around exactly yes mhm all right M
And can you explain we have um yes this material over here helps uh with the uh precipitation of minerals it will uh then uh the uh the minerals will collect over here which then we can uh clean out more efficiently rather than it would
Just uh clock up at the end do the to point yeah thank you yeah and you might be wondering guys how do we drill up two Kil kilomet down into the Earth well we use this this um Crusher this is all motorized all of these three things and scientists around
The world and Engineers have tried to find the best way and this is the one that works best because the the material comes into here gets crushed and also it can get crushed around here and it’s specifically made for when the motors are going to turn so you can see guys
These are not going to hit each other so it’s very interesting to look at all of this very specifically and it’s basically what we use well to crush and make coal into the Earth to put the pipes so yeah it’s very interesting here guys we have a diagram that can
Help us understand better how it works all right so first we take the steam water which become steam we put it into here and then we put it into this container steam it’s continues and it goes all the way down into the engine here where then it turns the turbine we
Can turn and go up and turns it into electricity and then it goes and well powers a nearby house or anything else like a light and then of course the cycle continues and continues but why do we want to put specifically geic plants in Iceland because we know that there are many
Countries and not in every country we have a GE plant and why is it specifically good to have one in I exactly yeah yes uh the uh most important part of this is of course the plate boundary as it’s represented by the Orange Line over here the plate
Boundary means we have two tectonic plates we have the North American tectonic plate over here in the west and then we have the Eurasian tectonic right over here in what is the difference between Eurasian and Europe uh euras because uh Europe is uh a continent in uh you know
Uh yeah I mean it should be two continents together because it is on the same tectonic plate but we separate them uh just culturally yeah right yeah uh but this plate boundy over here uh is moving these uh tectonic plates apart with that comes volcanos with when it
Gets separated then it pushes magma up exactly yes with volcanism we get more heat and because the plate boundary itself goes through the whole island then we have a lot of these geothermal uh systems that we can utilize and it’s specifically because there’s like but why does it have some much volcanic
Activity why specific why particularly yes exactly uh the separation of the tal plates produces volcanism but this volcanism does not explain why Iceland exists in the first place uh this thing over here which is called a hot spot explains why Iceland exists in the first place a hot spot is
Like if you can imagine a column of really hot magma material coming from really deep down from the earth uh and that is more volcanic activity on a place uh that would not have volcanic activity and this is where E15 came yes exactly the huge volcano that canceled
All the flights of Europe and was CED off but you can also Imagine That Hawaii is for example also a Hotpot you would not think that Hawaii would be a volcanic uh Island but because they have the Hotspot phenomenon then they have a lot more volcanic activity yeah thank you yeah no Problem N
