the European Union has made a policy
0:05
decision to stop the sale of the cars
0:07
that emit carbon dioxide after 2035 to
0:11
combat the adverse effects of climate
0:13
change in simple words they want to stop
0:16
licensing new petrol and diesel
0:19
vehicles in 2022 the European Parliament
0:23
EU commission and its member states came
0:25
to a policy agreement on this
0:28
matter however due to Germany's recent
0:31
objections and the decision had to be
0:33
kept confidential for the time being the
0:36
European Union considering promoting
0:38
vehicles with internal combustion
0:40
engines that run on E fuel rather than
0:43
fossil fuel EU regulations require cards
0:47
sold after 2035 to have zero carbon
0:52
emissions the fuel used in an engine
0:54
typically releases carbon dioxide into
0:57
atmosphere however in this situation
1:00
the amount of carbon dioxide emitted is
1:03
equivalent to the amount removed from
1:05
the atmosphere to create fuel e fuels
1:08
also known as synthetic fuels are an
1:11
emerging technology that have the
1:13
potential to play a significant role in
1:15
the transition towards a low carbon
1:17
economy e fuels are made by converting
1:20
renewable energy such as wind or solar
1:23
power into liquid fuel that can be used
1:26
in existing internal combustion engines
1:29
with without the need for any
1:33
modifications the process involves using
1:35
electricity to split water into hydrogen
1:38
and oxygen then combining the hydrogen
1:40
with carbon dioxide to produce a liquid
1:44
fuel e fuels are attractive because they
1:47
can be used in existing vehicles and
1:50
infrastructure avoiding the need for
1:52
costly and timec consuming upgrades they
1:54
can also be produced using renewable
1:57
energy making them a potential way to
2:00
decarbonize the transportation sector
2:03
which is responsible for a significant
2:06
portion of global carbon emissions there
2:08
are several types of e fuels including
2:11
methanol ethanol and Diesel methanol and
2:15
ethanol are alcohols that can be used in
2:17
gasoline engines while diesel e fuels
2:20
are produced using a different process
2:22
and can be used in deel engines these
2:25
fuels can be produced using different
2:27
combinations of renewable electricity
2:29
and carbon dioxide depending on the
2:31
specific requirements of the process
2:34
Porsche and several Partners have
2:36
started production of a climate neutral
2:38
efuel aimed at replacing gasoline in
2:41
vehicles with traditional internal
2:43
combustion engines one of the main
2:45
challenges facing e fuels is the cost of
2:48
production the process of converting
2:49
renewable energy into e fuels is
2:52
currently more expensive than producing
2:54
conventional fuels however as renewable
2:57
energy becomes cheaper and more abundant
3:00
the cost of e fuels is expected to come
3:03
down as well another challenge is the
3:05
Energy Efficiency of the process
3:08
converting renewable energy into e fuels
3:10
requires a significant amount of
3:12
electricity and there are losses at each
3:15
step of the process this means that the
3:17
Energy Efficiency of e fuels is lower
3:20
than that of conventional fuels which
3:23
could limit their adoption in the long
