the second part of all morning
00:00:03
many thanks for this invitation and the chance uh to tell you about a mobility
00:00:11
we have become much more technical these days uh
00:00:16
ah here we can see the mobility by the uh cable
00:00:34
after carlos planes bolts mobility is a very
00:00:38
gentle with uh the uh which covers many things
00:00:41
that's why we have to limit ourselves on the fuel a particular items and that's when you consider
00:00:46
competition between days another uh aspect many things up in the papers
00:00:50
all talking about mobility immobility morbidity many many things uh
00:00:55
this is a topic we could talk about four hours that's the reason why
00:01:00
uh this is a very uh current a topic
00:01:04
especially with the links between sustainability energy i would like
00:01:12
focus especially on a everything to do with the the road individual mobility
00:01:18
of cools will concentrate on the electric uh ah how many we have
00:01:23
on many they're all and also we would have to ask us that's how do we uh charge
00:01:28
how which are g. two when we recharge it and what all the other uh solutions that are
00:01:33
we will have for example with the h. two when the role that disturb individual
00:01:37
would like to show why your logic is would appear on the scene and also
00:01:43
how we cannot of all the the the matter related to the
00:01:47
i i. energy infrastructure a lot of that topic over the energy aspect
00:01:53
here we have some uh statistics uh that come from the
00:01:57
posted at the energy in a switcher land uh uh does well out here
00:02:02
uh shows that uh energy has to come from somewhere
00:02:06
and this day a discount especially from a organ petrol or
00:02:10
and and and this we have apart from ability here in the statistics for doesn't eighteen
00:02:17
you can see here the evolution uh and over the last a few years and the trend
00:02:21
let's see uh as uh there is some information buttons fall a mobility
00:02:26
this is a quasi descent but uh it we call covers roughly one set
00:02:31
of uh the the g. energy and uh we could underlies this uh further
00:02:37
all of this uh mobility pile out are in switzerland uh we have
00:02:40
you know a on the role of the the part uh on the road
00:02:44
some of it uh on the c. some of it on the train lines and that is why
00:02:49
it's of you're a d. so from now on
00:02:55
no weeds also talking about electrical something on because
00:02:59
this is an important topic where do we want to uh to get
00:03:03
to and you know that uh from monday overdose it is we have been
00:03:08
a meeting intimate made in order to talk about what could we do we seal too
00:03:12
uh in uh the feature yeah as mobility is uh where we wanted to go
00:03:17
for first uh whoa what a concert choose mobility with a somewhat efforts and the
00:03:23
conception by car as a dropped and lawton dropped all unfortunately the number of causes a
00:03:29
reason which is where the moment that we have not gained much is it going in the wrong a way and uh
00:03:36
what uh we gain by efficiency here we have realised i know total numbers
00:03:42
so we have to do something about this
00:03:45
the efficiency gain a ease uh it or not but i do rise in the mobility overall
00:03:53
uh there is a one will sing to look at which is that a
00:03:57
lot resupply a great role uh in terms of the contribution to a traffic
00:04:02
now let's look at the fact that in switzerland were like uh to uh oh
00:04:07
what kind of transport would like to have in switzerland uh we have some statistical data
00:04:11
and at the moment we have around ten thousand electric vehicles uh if they were putting together
00:04:17
and once again uh charges through a charge an
00:04:21
pointer sockets uh they have been sold a diesel
00:04:26
about ten thousand it with records that was sold out of three
00:04:29
hundred thousand vehicles and twenty eighteen uh which represents around three percent
00:04:33
of the total uh the number of cars in switzerland this is the situation as of today and uh
00:04:39
now how can we uh charge t. c. who want to
00:04:41
charges who's a little part conception roll up our this is the
00:04:46
the question of the duration of stay how long will i keep
00:04:49
my car on the a cop out because it's completely different from
00:04:54
the uh charging a recharging that's always a few very core so how many probably chartered weapons was not we have
00:05:01
two thousand five hundred probably charges in switzerland a public event about and we have to uh see what kind of uh
00:05:07
however looking that uh most of the charging stations
00:05:11
are quite impressive we can look at that in details
00:05:13
where do we find them and uh uh in terms of a high powered charging up once
00:05:20
we have sweets was a land uh we have uh how we have a us um uh
00:05:25
d. c. uh charging station off around the three hundred uh uh
00:05:29
charging stations of that's a size at about seventy people what's a that
00:05:35
is a religious today but that we have to find the right cable or
00:05:38
where there were out whole mall uh at a a place of work and uh
00:05:43
all i've done is to be look it to and yet if we look at
00:05:46
it into wait a always a greater consumption for example to heed the car with uh
00:05:52
it's a free for a classic kind of car but yet but take this
00:05:56
into account foreigner prick of a call and yet we have to ask ourselves about
00:06:00
the origin of electric energy in switzerland comes from my usual when you create a this is
00:06:05
the situation today which is that's i'm interested that does not they meet a c. o. two
00:06:12
that's an element uh that we need to reflect on a we have
00:06:16
a sweet as an uh stations uh today it to a charter car
00:06:21
and uh we're going out to a thousand five hundred to three thousand and
00:06:26
we feel that we almost ever get what to think about the charging time
00:06:30
if the infrastructure in place at the moment is that's sufficient what would i do
00:06:38
so now we have to ask ourselves these two particular questions where does electricity come from
00:06:43
it must come from somewhere and uh ideally it would come from solar and the wind
00:06:49
power and in germany internal also we have some uh when a power turbines that uh
00:06:55
or in operation and uh we also have some okay boards in order to
00:06:59
draw that energy and the city energy circuit about what's that takes place in a
00:07:04
if it's around here we have a a petrol and or uh which is
00:07:08
part of the transport energy makes and would like to change uh this uh
00:07:13
abortion and we have seen that diagram already and we have the electricity here
00:07:17
the represented a by sixty percent of what what it was itchy and set a five
00:07:21
percent for nuclear uh what we want in the future as you know would like to
00:07:25
have a change of energy system up until two thousand and fifty
00:07:28
and for that i would have to be price that part yeah so
00:07:32
yeah for would have to fit the nuclear if uh we have to
00:07:35
feed that we have something to do already but this part yeah i i
00:07:45
this says as for the infrastructure intuition of a primary
00:07:49
energy just second question is at what time when would
00:07:53
i charge which some of the days by start charging let's see machine that we have four point six median
00:07:58
of if it causes was attending twenty fifty let's imagine doesn't twenty fifty all castle electric what we do
00:08:09
let's assume that uh during the day and would not say that everybody charged a car descent time but
00:08:14
that's just a assume that ten percent of cost jobs at the same time as i stated earlier on
00:08:20
most of the charge and phone sorta round is seven q. the white and even
00:08:26
to get a lot but let's plan seventy to what as when twenty fifty now
00:08:30
you know scenarios so we preach austin percent or other send a movie lover
00:08:36
uh an instant power of a roughly i it's a times leds that that's not negligible if we do decide
00:08:42
no had because love it more relaxed a with sleeping and the car is being jobs
00:08:47
uh well worse tapes with assault charges three point five could what's uh and therefore if
00:08:52
we just look at ten percent of jobs uh uh at the same time looking at
00:08:56
one point five laps tight but much that uh by twenty fifty is probably of uh
00:09:03
even wouldn't there be no two weeks even if it's a five times a smaller
00:09:10
as for the cost uh though all those stationary for ninety percent of the then i would like to look at this
00:09:16
a further into tears what happens when that um we charge at walmart work
00:09:22
we which are twenty never is necessary we're asking ourselves what's powwow
00:09:27
uh would be required for charging we're talking a lot about would be charging fast charging one hundred uh
00:09:32
what one hundred twenty you know what one hundred fifty or what it's a small detail doesn't change much
00:09:41
we have uh the i. s. s. yeah i'm from
00:09:46
switzerland and uh mister shaw chicago that analysis uh oh
00:09:50
at what time will most cost the charger here doing
00:09:53
today into cars all uh being driven uh doing today
00:09:58
the charge them charge him roughly at four p. m. eight p. m.
00:10:02
this is the one which are the cosmos it doesn't change much uh between uh the week
00:10:07
and uh do week uh and uh when we drive around to do and see friends and family
00:10:13
now we have roughly the same same if we compare this with a solar power
00:10:18
you know june no it's a pretty good in december uh the sun is not so
00:10:23
a stronger and it's not as good so whether difficulty when do
00:10:27
we have green energy at our disposal and when do we want to
00:10:31
john of the cross so we have to think about how
00:10:34
can we stock energy what not the chart what should we
00:10:37
do a cruel so program all computer ourselves okay charge your
00:10:41
car what you're driving by this is a matter of uh
00:10:45
you are as numerous a shade and visualisation another specialist in that topic and uh experts in that area
00:10:51
can a tackle that problem now if i was to give you another
00:10:55
example if everybody watches their car into some out once again within twenty fifty
00:11:00
defeating station id i weigh in germany for example twenty costed out
00:11:05
at the same time in twenty minutes to charge the car too
00:11:09
continued a holiday tree uh there will go to the charging point that that don't want to charge
00:11:14
a hundred percent just eighty percent because was twenty percent tax
00:11:19
a lot more time so if you want to charge edge percent
00:11:22
fate in twenty minutes uh we need a facelift you could uh
00:11:24
what uh which is okay for a two hundred kilometres distance lawfully
00:11:31
uh so depending on the car of course i'm your nominee using a a nice car but as a
00:11:37
as a model for this analysis if we use a more modest car we could divide the number by two
00:11:42
so three make a quieter must be available full only twenty cost
00:11:46
but when holiday so there are many cars behind me curing yep
00:11:51
then uh stations remake yeah what must be available uh wait sure
00:11:56
corresponds so to roughly an average industry complex and uh
00:12:00
we would need to transform a two intermediate voltage transmission great
00:12:04
uh these days and i've only taken of example was ten cars uh but that's in twenty minutes slot
00:12:11
and now we have to convince somebody who would install that a system for the
00:12:15
power electric this energy distribution on the model way according to the needs but we didn't
00:12:20
twenty fifty and i hope that by dan all these problems would be
00:12:23
solved and uh we need to address the question of how would we
00:12:28
managed infrastructure one set of infrastructure and that's what i am
00:12:31
at the moment and uh because of the time that resulted
00:12:34
uh i will go beat faster and i will shorten my presentation uh just to think
00:12:40
how can they infrastructure be allocated a distaste better sessions one of
00:12:44
that to start with start ways people aware looking for that missus bands
00:12:49
oh troll of in eighteen eighty six that she was uh going to get a few that the pharmacies
00:12:54
and everybody was doing uh in that manner for about twenty years and the discharging stations this few stations
00:13:00
arrived three years later and the first one meeting you will be cool but
00:13:05
a field other colour sets what about twenty years later
00:13:08
i took some time and who pays for the infrastructure three
00:13:12
does and three hundred sixty seven feeding stations um a
00:13:15
few stations in switzerland this was paid for by date
00:13:19
industry uh because there where enough people uh who wanted to have a
00:13:24
nice car driving around and let's not forget that a electric cars tech
00:13:30
ten times longer or fifty times longer to jobs and therefore we need
00:13:34
ten times as many uh stations so in twenty fifties would not be enough um so who would pay for this
00:13:40
this is the main question and you for once again or short on my presentation uh and uh we we have
00:13:45
enough gas to do that uh with industry to so and to really shorten my presentation
00:13:51
i would submit that by saying that i think that would not be able to leave without a nice attentions not to help
00:13:57
for the infrastructure to be available for cars in order to solve that problem
00:14:01
which is a chicken and egg a situation as such if i can say so
00:14:08
now what we've disclosed if we look at all uses of
00:14:12
ancient abide by ourselves uh in the and uh we have to
00:14:15
ask ourselves so we investing going a rightist um electric system all
00:14:19
another ceased um who we want to have uh some actually power electricity we just
00:14:25
i need to ask ourselves all too shall we uh choose electricity or hydrogen i'm really
00:14:30
gives us aside at the moment imagining that within twenty fifty and what are the differences between
00:14:37
due to uh uh modes there is to show i actually option
00:14:42
uh as a we're talking about tess like for example are these days
00:14:45
there is also the possible hydrogen option with a very uh much a short um a charge in time and uh
00:14:52
uh in principle we could do so all we have to add on to shape could be stopped uh uh with uh
00:14:57
that mentioned up like oh we just go for some years into the future
00:15:02
this would be a easier but once again uh this is in the room sofa sensation at the moment
00:15:08
in the sense that uh it exists in laboratories in on a bigger size but once again
00:15:12
uh this is much more closely at the moment so at the moment or as you have notice
00:15:17
we're not talking about mobility them all with talking about infrastructure uh energy infrastructure so in order to
00:15:24
make a distinction between it was a. t. and i don't yeah there is a small diagram here
00:15:28
that i've copied by g. uh energy of this in the united states or we have the energy density
00:15:36
compared to between a a chisel gasoline hydrogen a mess and
00:15:44
and uh we have the density per volume and the number of units uh how can
00:15:48
we c. d.'s on the right in terms of hydrogen and as much density per kilogram or
00:15:54
ah ha love uh uh in this uh diagram are we i still need to have a contain a
00:16:01
for the energy and if you put hydrogen here the number
00:16:05
drops from one twenty hundred twenty to one or two so
00:16:10
what's important to know is where all the batteries to listen batteries
00:16:15
all lawfully on the right hand side yeah oh at zero point one zero point two
00:16:20
in terms of volume in terms of density per kilogram the batteries are here and uh
00:16:27
this is something to keep in mind if we now i look at to to uh
00:16:32
different cars uh uh we can uh see that we
00:16:36
could live stock uh i do general sixty we is uh
00:16:40
town car to not product you meet up okay program as you can see here and uh are there you
00:16:46
can also see dietrich the battery in the corner but yet the car is ten times then sat down uh
00:16:53
for native trees itchy uh uh if we can uh what does that say involve for filling station
00:16:59
one thing we cannot say here is the time scale because of the intensity of the and the density of the hydrogen
00:17:07
we have a a factor for most two one two fifty i know of that to a
00:17:11
charge on hydrogen a car compared to nitpick coffee
00:17:14
chances and therefore will be any infrastructure oh so
00:17:20
i think that this or will be all clear for us will send me an sometime in my presentation
00:17:34
and now we're asking ourselves the question no she's not a
00:17:39
hydrogen seems absolutely beautiful but yet if we're looking at a
00:17:42
energy efficiency uh in terms of uh energy infrastructure hydrogen is not so great
00:17:50
okay mm who forward
00:17:59
compared to to uh the classic um internal combustion and
00:18:03
a petrol a hybrid car t. v. footage weaker to slow
00:18:10
oh hydrogen car does all the four men candidates
00:18:12
for comparison so if we are looking at uh improving
00:18:20
the efficiency we can uh look at i really don't know i'm not talking about this anymore but in order
00:18:26
to completely eliminate a c. o. two hardwood will not
00:18:29
work so therefore we just are these two candidates left
00:18:35
which is a hydrogen car with the hydrogen tank or a
00:18:40
convertible which uh which charges or a battery the batteries here
00:18:44
and this is a battery that gets the engine to work so hard to gen klaus similar to an electric out of stuff
00:18:49
from the fact that stops hydrogen different manner and just to
00:18:53
be converted again and that is where we're where we're losing efficiency
00:18:57
in order to convert hydrogen to electricity via their conversion we lose fifty percent and we can then
00:19:04
keep in mind that this would not change much in the next few years this is the uh current situations so
00:19:10
here if i was to quickly compared to the efficiency break between first of all take energy
00:19:17
and also convert so
00:19:21
he said cause uh just exeter approaching fifty percent of uh
00:19:26
the car driving fifty percent of their peak hour and uh
00:19:30
yeah project car wasn't around twenty three percent because you have to convert to hydrogen and we convert
00:19:35
so this seems a a bad and we're can improve these
00:19:38
uh and we also have to sort of the stock stocking
00:19:41
problem stock ooh we can
00:19:48
already stock a pretty whereas so
00:19:50
we will not change much uh diseases around twenty five percent or
00:19:54
before we look at the interest to stock h. and low cost okay should
00:19:59
we can to was factor sixties of six history was a factor of two
00:20:03
in terms of efficiency i'm not talking about the battery you can't be days the battery needs to be treated well
00:20:14
we have a great part uh to to to uh do ways in
00:20:18
terms of ability had now otherwise it would not to get sorted or
00:20:22
uh so to production uh it's possible but not was i put cards that we find market the moment we need to find
00:20:27
we are hybrid cars i would too badly reliably car my car was twenty years
00:20:32
old but i would do not find a real agreed cart worse its name as such
00:20:38
and the not a ought to really eliminate a suit to
00:20:42
we need to even avoid hybrid and we have to go
00:20:46
for electrical i trudge an uh an uh mobility
00:20:50
and makes sense only if directory city uh production
00:20:54
is a renewable in norway yes in switzerland yeah as in
00:20:57
denmark yes in germany in china i don't have the diagrams here
00:21:03
i wish we were to look at that that's not the case at the moment to where it is it is a dirty these days but
00:21:09
here in switzerland all of a sudden but talking about the fact that
00:21:12
electricity is becoming don't you see so the infrastructure is a key element
00:21:16
uh in order to get to grey mobility and in order to obtain this
00:21:21
we need to uh massively raised just solar energy and a wooden chair was talking
00:21:27
oh we says some people in switzerland in band and the estimate so that uh in order to replace nuclear will
00:21:33
we need to have at least certain times more than today and if we were to go to agree mobility we knew too
00:21:40
i'll go to fifty a fact times factor but that's
00:21:44
not a problem as such a but maybe it's a
00:21:48
case question of willpower and we have not yet even
00:21:51
addressed a particular difficulty to seem so negative that uh
00:21:55
how could i finish with something positive i've been very green for the last thirty uh send i would like
00:22:00
to mention that for small distances it because already glued
00:22:04
but finding the next week i'll for small distance it's uh
00:22:08
well it's impossible for the next five years so let's uh go
00:22:11
that way i just been covered twenty percent of energy for transport
00:22:14
for small distances eighty percent of energy and i have not shown the numbers on screen
00:22:19
that eighty percent of energy in transport according
00:22:22
to with long distances and for long distances here
00:22:27
this is where we have a problem with electric cars and it's quite easy for the next five to ten years for it to cast
00:22:33
for short distances for long distances over the next ten years or more hydrogen cost
00:22:42
so what would we do ninety six and uh we need to find the
00:22:46
car park in the city centre downtown where people who
00:22:49
commute to go to a doctor want to park their car
00:22:53
we is that many charging points not by to the dawson's but by the hundreds in order to
00:22:59
cover and opened the park cover the car parks who uses solar panels are
00:23:06
for example given yeah this is the case when you come back to that
00:23:09
oh when you have that could at four so i have all gone over
00:23:13
my look at a time by three minutes and i would add another element to that uh many times
00:23:20
are just wanted to and uh and i want to thank restart but i just want to what two
00:23:26
or three a smaller amounts to say that uh once we have real today's recommendations how could we uh quickly
00:23:33
um look at that impact is what is important of course is the particular object either
00:23:38
for example if the carbon uh neutrality he's those set up then we could
00:23:44
go to to the configuration state should state in order to uh implement this uh
00:23:49
covered shoulder covered a card box in order to then
00:23:52
go to us the uh the dingo and it's very important
00:23:57
to follow uh the recesses it is production and in that case uh
00:24:01
do people use to offer that was a great in that manner random
00:24:06
often a ad at a stage or this uh stages a forgotten because uh then uh
00:24:13
we'll look at whether we're going a forward with your of uh all was that not
00:24:20
uh did not find any uh demand then their fault did we
00:24:25
for a shot and uh in that sense i want to uh
00:24:28
mentioned that said technological evolution as well describe a priest of uh
00:24:32
now get an objective oftentimes we almost manage not quite but there's also
00:24:37
the gap between uh the technological evolution and what's in
00:24:41
reality as was stated this morning about you miss tamara
00:24:46
is that if i want to change a word as it is at the moment how can i create this vision
00:24:52
that's people start so call or that object chief darts or a one pushes people to want
00:24:59
to charge on the question is how can people buying in to to change in order to
00:25:05
identify the man not to participate and to be
00:25:08
a stack all those in that particular a situation that
00:25:11
i want to say that that i think that's in order to guarantee the set information we need to ask
00:25:17
to add this it's additional uh axes we some parts eventually uh
00:25:23
a step so which uh sometimes can limit the time in terms of regulation so arena
00:25:29
uh terms of a people's vote if it's a implemented well so i think that is where
00:25:34
the few elements that i wanted to add the on top of the technological side or to say
00:25:39
that uh we need to reflect on these two axes in order to uh get to uh no objective
00:25:46
and to move forward with energy transition on a more global manner and uh
00:25:51
more specifically uh by integrating a mobility in the energy of planning
00:25:56
that is that being carried out and on the days uh with a
00:26:00
stop uh taking your time and uh you're free to ask any questions
