💫 Summary
Elon Musk considers hydrogen fuel cells for vehicles to be inefficient and a waste of energy compared to battery-powered electric vehicles, due to the energy lost in the production, transport, and conversion processes of hydrogen. While hydrogen fuel cells may have advantages for heavy-duty and long-distance transportation, Tesla focuses on battery-powered vehicles due to their scalability and existing infrastructure. However, both technologies have their pros and cons and can coexist depending on specific use cases and advancements in efficiency.
✨ Highlights📊 Transcript
The main problem with producing pure hydrogen for fuel cells is the process of electrolysis, which requires electricity to split water into hydrogen and oxygen.
02:43
Hydrogen atoms always stick to other elements, so separating hydrogen from other elements is necessary to obtain pure hydrogen.
Pure hydrogen is necessary for the operation of a hydrogen-based fuel cell.
Pure hydrogen can be obtained through electrolysis, which uses electricity to split water into hydrogen and oxygen.
Tesla does not manufacture hydrogen vehicles due to the lack of infrastructure for hydrogen refueling and the efficiency of their existing battery-powered system.
10:52
Hydrogen vehicles can be charged in about 5 minutes compared to the longer charging time for battery-powered electric vehicles.
Finding a place to fill up with hydrogen can be difficult or impossible depending on where you live.
Tesla already has a well-functioning infrastructure for electric superchargers but not for hydrogen refueling.
The efficiency of Tesla's existing battery-powered system allows them to scale their electrical architecture, motors, and battery cells.
00:00Let's talk about the relationship
00:01between hydrogen and
00:03electric vehicle propulsion In fact, it's been
00:06said that Elon Musk is not a fan
00:08of hydrogen powered vehicles It
00:11's rare that anyone in the
00:12automotive industry agrees with Iron on an issue
00:14but he went so far as to
00:17call it incredible ignorance there
00:19There aren't many hydrogen vehicles
00:20on the market, in fact I think
00:23only one or two models have been released so far.
00:25However, we are
00:27also aware that battery-powered
00:29vehicles have significant disadvantages and
00:32we are also aware that the
00:34problems we are currently
00:35facing are getting worse
00:37In reality it is metals such as
00:39nickel cobalt aluminum manganese and
00:42lithium that are necessary for the production of
00:43lithium-ion batteries.
00:45These materials have always been
00:48expensive and difficult to obtain but in
00:50the last six months the market
00:52for these materials has become completely explosive
00:53The
00:55electric vehicle market has lost a bad image.
00:57
00:58We discussed whether this
01:00transformation is actually achievable
01:01or even sustainable. Is
01:04hydrogen really as unnecessary as
01:06some claim? After all, it is the
01:09most common element in the cosmos that we
01:11know today and if we could not use it as a
01:13fuel source would that be
01:15a big insult to our
01:17universe but if not what is the
01:19exact reason more importantly is it
01:22possible to make hydrogen less useless
01:24than it is in the automotive industry today
01:26
01:28unless it is really a futuristic
01:30option we try more in this video
01:33to find out but before you start do
01:36n't forget to subscribe to the channel
01:38by
01:39turning on all notifications so you
01:41don't miss the latest Tesla news
01:42let's go now we all
01:46know that hydrogen is a fuel
01:48that burns easily you just have to see
01:50what with the old Hindenburg
01:52To understand this,
01:54however, there is
01:56no combustion in hydrogen, at least
01:58if it works properly. When
02:01the vehicle is started, the hydrogen is
02:03released into a fuel cell where the
02:04energy contained in it
02:06is converted into electricity. A
02:08hydrogen fuel cell is
02:10one in structure and functioning Battery
02:12very similar it splits electrons that
02:15
02:16pass through a conductive circuit between the two sides with the help of
02:18a cathode and an anode with an
02:20electrolysis separator in between
02:22therefore hydrogen gas enters
02:25the cell through the anode or negative side
02:27where it comes into contact with a catalytic platinum separator
02:29the
02:31hydrogen molecules or H2 then tend
02:34to split and release their two
02:36electrons when they
02:38touch the platinum remaining
02:40hydrogen ions are now drawn through the
02:41electrolyte and indicator or
02:43positive side of the cell while
02:46free electrons enter the conductor and through
02:48the electrical circuit of
02:50the car drives
02:51also note that has two or
02:54water is created when electrons and
02:56hydrogen ions recombine with oxygen molecules
02:58let's just
03:00go back to hydrogen because there
03:02is a lot of scientific magic in it at
03:05the anode or negatively charged side
03:07the hydrogen enters the cell
03:09oxygen is passed through the cathode of the
03:11Cell or the positive side
03:13introduced the hydrogen then has to
03:15get from the anode to the cathode but
03:17before that it has to react with the platinum
03:19
03:21to split into electrons and ions only the conductive
03:24circuit allows electrons
03:26to leave the anode and this circuit generates
03:28electricity but the ions also have to
03:30leave the anode which you can only do
03:32by passing through the electrolysis repair
03:34and when you all reach the cathode
03:37they combine there with
03:39the oxygen to form water which then
03:41leaves the teeth as an internal byproduct
03:43but we have to admit it all sounds
03:46pretty great and promising
03:48but then why does Elon Musk
03:50stubbornly keep him crazy we really need to take
03:53a step back and
03:55look at the bigger picture to
03:57fully understand the process where does
03:59the hydrogen that
04:01powers the fuel cell actually come from note
04:03that hydrogen is the most common element in the
04:06universe it is the first in the periodic table
04:09by the way Element it is the
04:12lightest element in the world
04:13hydrogen is a wonderful substance
04:16that is present everywhere but the earth does
04:19not have pure hydrogen due to
04:21its sticky nature
04:23hydrogen atoms always stick to other
04:25elements such as oxygen
04:27so we have to separate hydrogen from
04:29another element to get the pure one
04:31Obtaining hydrogen, which is necessary for the
04:33operation of a hydrogen-based
04:34fuel cell and that's
04:37actually the main problem, is
04:39electrolysis, which essentially uses
04:41electricity to split water into hydrogen and
04:43oxygen The
04:45
04:46
04:48
04:50opposite of
04:52a fuel cell is also
04:54hydrogen can be converted into green hydrogen,
04:56a fuel that does
04:58not emit pollutants if the
05:00electrolyser is powered by electricity from renewable
05:02sources such as solar or wind energy.
05:04However, the production
05:07of pure hydrogen from a
05:08fossil source such as natural gas is the
05:10alternative method of steam reforming
05:12is the term used to
05:14refer to this process
05:16the catalyst is used to break down the
05:19mixture into hydrogen and carbon monoxide
05:21after combining it with steam and
05:23methane in a heated
05:24high pressure atmosphere the
05:27carbon is thus harmfully released into the
05:28environment while the hydrogen
05:30This substance is preserved, the
05:33gray hydrogen is known and the
05:36production of green hydrogen is
05:38significantly more expensive than that of
05:39warm hydrogen which process do they
05:42use in their opinion so
05:44most manufacturers
05:45
05:46use the wrong
05:49method to produce hydrogen of course which is disappointing but about
05:5195% of it
05:54In any case, this gas has to be
05:57compressed and cooled during production
05:59and transported to a water pen filling station.
06:00All of these steps
06:03require a lot of fossil energy. Don't
06:06worry. I'll go into
06:08why batteries are also bad in a moment. We
06:10just concentrate on
06:12one task at a time leave no
06:14stone unturned to understand both parties
06:16so let's get to the
06:18point and say that efficiency
06:20
06:21is the main issue with a hydrogen vehicle energy moves
06:24in and out of the body but how much
06:27energy is lost in the process of
06:29producing gas its transport its
06:32storage and the conversion of
06:33hydrogen into energy are processes that
06:36waste energy the energy input
06:38for our hydrogen fuel cell
06:40begins with the production of the gas and
06:42the energy output is the ability to
06:44turn the vehicle's speech
06:46the loss in the middle is often
06:48around 62% or more in the worst case There
06:52can be a loss of up to 8
06:54and 70%, between 8 and
06:5730 and 22% of a
07:00vehicle's fuel can be converted into hydrogen
07:02and although it is not ideal,
07:04it is still superior to an internal combustion engine
07:06whose efficiency is only 13%
07:09
07:11
07:14
07:17However, a battery electric car whose efficiency is between three and 70 and 80% surpasses these two fuels in terms of efficiency
07:19and that's why Elon Musk thinks hydrogen
07:22fuel cells are really crazy
07:23after all, Elon is obsessed with efficiency
07:26basically that's the division of
07:28everything Tesla does all the measures it
07:31takes aim to
07:34increase productivity and efficiency but it can
07:37also be a marketing
07:41because what's better than a controversial
07:43way to get people
07:46talking about it so it's clear batteries are
07:48a better source of energy than
07:50hydrogen which according to Elon Musk
07:52is an unreasonable fuel but In
07:55reality it's not that simple in
07:57truth both sides have a long
07:59list of pros and cons we
08:02now know that one of the problems with
08:04batteries is that they require a lot of
08:06mining and processing to
08:08get the materials needed it
08:10involves creating huge earth yards
08:12and spewing out a ton of dangerous chemicals
08:14it's like
08:17hitting the environment before hitting it
08:19when it's down furthermore
08:22the manufacturing sector is another
08:24factor to consider it
08:26uses a ton of energy
08:27while producing a ton of
08:29hazardous waste the end result is
08:32therefore one Lithium ion battery cell
08:34that only works for a short time before
08:36it deteriorates more and more until
08:38we throw it away and buy a new cell
08:40
08:41at least in the worst case but
08:43unfortunately this is still largely true today
08:45things can and
08:47most likely will get better and become
08:49less dependent on rare metals
08:52chemical batteries such as LFP
08:53Lithium iron phosphate
08:56engineers want
08:58to implement a closed loop and
09:00
09:02recycle battery cells on a large scale we use more green and
09:05renewable energy and to power our industry
09:07and extractive sectors
09:09the batteries are not
09:11fantastic but they can not improve
09:13and they still have There is a long way
09:16to go, however, there are also
09:18ups and downs on the water pens. We
09:21now know that it is possible to produce green
09:23hydrogen through the combination of
09:25electrolysis and renewable energies,
09:27which is fantastic but in
09:30terms of the environmental impact,
09:32electrolysers and fuel cells are
09:33not really there advantageous about
09:35five minutes ago we talked about
09:37the platinum catalyst in the center of the
09:40fuel cell yes it
09:42looks like they need this device
09:44to produce hydrogen gas
09:46and convert it into energy
09:47the system still requires
09:50rare metals and
09:52platinum flu metals to work, so there
09:55will still be mining and
09:56raw material extraction, but the
09:58ecosystem will be trampled underfoot.
10:02However, green hydrogen is not a
10:03hopeless case like batteries,
10:06people know that things
10:07can be improved and are working hard
10:09to improve the situation. There
10:12
10:14will also be more efficient hydrogen electrolysis soon More and
10:16more wind and solar farms will be built to
10:19supply them with electricity and ultimately
10:21it will be the most cost-effective way
10:23to produce hydrogen and therefore
10:26the most popular, which is better then
10:29assuming batteries and hydrogen
10:31are not completely useless,
10:33in fact we don't have to choose
10:35one or the other the other decide we
10:37can use the advantages of each technology
10:39separately but batteries are
10:42undoubtedly the best solution for
10:43commercially produced
10:45passenger cars today we need
10:47electric vehicles that are enough for everyday use
10:50this is possible because mains power
10:52is cheap and easy to obtain yes a
10:55hydrogen vehicle can in about 5
10:57minutes to charge compared to
10:59the five and 40 minutes to an hour
11:01it currently takes to fully charge
11:03a battery-powered
11:05electric vehicle, but
11:07you will need to find a place to
11:09fill up with hydrogen, which depending on where you
11:11live can be difficult if not
11:13impossible if electricity is
11:15constantly physically available to us surrounds there is no
11:17point in demolishing gas stations to
11:19build hydrogen stations or
11:21
11:23replacing gasoline tankers with hydrogen tankers, just connect your car
11:25to the network that we already
11:27have
11:28with a little preparation and perseverance
11:30you can drive wherever you want since
11:33hydrogen tanks
11:34can hold more energy than Batteries and
11:36can be recharged quickly
11:38they are ideal for heavy duty vehicles
11:40and commercial vehicles Hydrogen
11:42fuel cells are therefore
11:44probably the best option for
11:45industrial machines that use a lot of energy
11:47this solution has already been
11:50tested with some forklifts and
11:52has proven to be quite successful
11:54therefore hydrogen is another good one
11:56Choice for road transport over long
11:58distances Again, the longer
12:01range and faster
12:02charging times make the difference between
12:04an electric semi-trailer and a
12:05diesel-powered semi-trailer almost
12:07non-existent, so you
12:10may be wondering why Tesla
12:11makes a battery-powered truck,
12:14again for commercial
12:16efficiency reasons already
12:19batteries
12:20hydrogen fuel cells are
12:22not made by Tesla tesla
12:24already has electric superchargers but
12:26they don't have the infrastructure for
12:28hydrogen refueling if it already
12:31
12:33has a perfectly functioning system it wouldn't make sense for the company
12:34
12:36to develop and
12:37introduce a brand new technology beyond that
12:40Semit Tesla powered by the same engines
12:42as the rest of the Tesla range.
12:44Efficiency is the ability to scale the same
12:46electrical architecture motors and
12:48battery cells
12:50while using more of them,
12:52although a hydrogen-powered
12:54tractor-trailer won't go as far as
12:56the semi Tesla doesn't mean that that it's
12:58worthless it's just more limited which
13:00isn't the end of the world it's
13:03quite suitable so we
13:05managed to answer the original question
13:07we had in mind I
13:10'm not sure but I think the
13:12focus is on the lessons
13:14we learned this way
13:16what do you think about hydrogen
13:17energy after
13:19watching the full video do
13:21you agree with Elon Musk's claim that
