hello and welcome to just ever think so
00:00:12.869 00:00:12.879 last week we had a look at hydrogen
00:00:14.730 00:00:14.740 storage and I think it's fair to say
00:00:16.410 00:00:16.420 it's been a pretty interesting week
00:00:18.090 00:00:18.100 since then more than 80,000 people
00:00:20.190 00:00:20.200 watched that video and 6,000 new
00:00:22.770 00:00:22.780 subscribers have joined the channel just
00:00:24.360 00:00:24.370 in the last seven days which is
00:00:26.340 00:00:26.350 absolutely phenomenal and a massive
00:00:28.680 00:00:28.690 thank you to all of you there's
00:00:30.060 00:00:30.070 obviously some strength of feeling out
00:00:31.710 00:00:31.720 there on both sides of the hydrogen
00:00:33.420 00:00:33.430 debate and that came through loud and
00:00:35.069 00:00:35.079 clear in your comments last week there
00:00:37.620 00:00:37.630 was quite a bit of feedback suggesting
00:00:39.270 00:00:39.280 that there wasn't enough emphasis in
00:00:40.860 00:00:40.870 last week's program on the inherent
00:00:43.229 00:00:43.239 inefficiencies of the hydrogen
00:00:44.940 00:00:44.950 conversion process and that's a
00:00:46.200 00:00:46.210 perfectly reasonable observation in fact
00:00:48.810 00:00:48.820 it's something we looked at in the video
00:00:50.370 00:00:50.380 that we did last September which you can
00:00:52.709 00:00:52.719 click and have a look at up there but in
00:00:54.660 00:00:54.670 the meantime here is a quick summary
00:00:56.420 00:00:56.430 water electrolysis loses about 30% of
00:00:59.880 00:00:59.890 the energy that's put into the reaction
00:01:01.139 00:01:01.149 there's a slightly more efficient
00:01:03.119 00:01:03.129 version called proton exchange membrane
00:01:04.740 00:01:04.750 electrolysis which improves the output
00:01:07.020 00:01:07.030 from 70 to 80 percent but this is still
00:01:09.779 00:01:09.789 a lot less efficient than the 99 percent
00:01:11.459 00:01:11.469 charging efficiency of a lithium-ion
00:01:13.800 00:01:13.810 battery freezing hydrogen to about 20
00:01:17.219 00:01:17.229 degrees above absolute zero loses around
00:01:19.859 00:01:19.869 40 percent of the available energy
00:01:21.389 00:01:21.399 whereas pressurization loses about 13%
00:01:24.840 00:01:24.850 so pressurization tends to be the more
00:01:26.999 00:01:27.009 common option transporting the fuel can
00:01:30.179 00:01:30.189 cost anything between 10% and 40% of the
00:01:32.849 00:01:32.859 energy depending on the transport method
00:01:34.679 00:01:34.689 and the distance of travel and then
00:01:36.629 00:01:36.639 you've got energy losses inside the fuel
00:01:38.609 00:01:38.619 cell modern hydrogen fuel cells are
00:01:40.709 00:01:40.719 about 60 percent efficient the other 40
00:01:43.230 00:01:43.240 percent is mostly heat loss taking
00:01:45.239 00:01:45.249 everything into account you get an
00:01:46.589 00:01:46.599 overall efficiency for lithium-ion
00:01:48.300 00:01:48.310 vehicle batteries of about 75 percent
00:01:50.819 00:01:50.829 compared to 35% for hydrogen fuel cells
00:01:54.209 00:01:54.219 which equates to a cost per mile for
00:01:56.039 00:01:56.049 hydrogen fuel cell vehicles that's about
00:01:58.469 00:01:58.479 eight times higher than the cost of
00:02:00.479 00:02:00.489 lithium-ion battery powered vehicles so
00:02:02.760 00:02:02.770 for small personal vehicles it's fair to
00:02:05.010 00:02:05.020 say the hydrogen has got an uphill
00:02:07.379 00:02:07.389 battle in the marketplace
00:02:09.240 00:02:09.250 but by the way let's not forget that
00:02:10.859 00:02:10.869 internal combustion engines can only
00:02:13.170 00:02:13.180 operate at about 20
00:02:14.390 00:02:14.400 to 30% efficiency because the majority
00:02:16.759 00:02:16.769 of their energy is lost to heat so in
00:02:19.369 00:02:19.379 any comparison ice engines come out as
00:02:21.619 00:02:21.629 the poor relation some of you also felt
00:02:23.869 00:02:23.879 that hydrogen was just a backdoor way of
00:02:25.940 00:02:25.950 allowing the fossil fuel producers to
00:02:28.069 00:02:28.079 continue producing fossil fuels after
00:02:31.099 00:02:31.109 all as we mentioned last week the
00:02:32.660 00:02:32.670 industrial process of steam reforming
00:02:34.809 00:02:34.819 produces hydrogen by splitting natural
00:02:37.250 00:02:37.260 gas otherwise known as methane or
00:02:39.470 00:02:39.480 methane in the United States a process
00:02:41.899 00:02:41.909 which releases co2 and the concept of
00:02:45.410 00:02:45.420 adding hydrogen to existing methane
00:02:47.629 00:02:47.639 natural gas pipelines as a kind of
00:02:49.759 00:02:49.769 bridging fuel to ease down
00:02:51.830 00:02:51.840 natural gas production will some say
00:02:54.589 00:02:54.599 also allow the fossil fuel companies to
00:02:57.229 00:02:57.239 fudge their figures and make it look
00:02:59.089 00:02:59.099 like they're doing a much better job
00:03:00.289 00:03:00.299 than they really are and one or two of
00:03:02.119 00:03:02.129 you over there in the United States also
00:03:03.649 00:03:03.659 suggested that any grid level
00:03:05.839 00:03:05.849 implementation of hydrogen is just
00:03:07.910 00:03:07.920 shifting the emphasis from one
00:03:09.410 00:03:09.420 monopolistic power producer to another
00:03:11.780 00:03:11.790 allowing the shadowy Monument to
00:03:14.059 00:03:14.069 maintain their grip on power and still
00:03:16.640 00:03:16.650 control the prices that you and I pay
00:03:18.589 00:03:18.599 for our energy there are all valid
00:03:20.720 00:03:20.730 points that deserve the benefit of full
00:03:22.610 00:03:22.620 debate which is probably something
00:03:24.170 00:03:24.180 that's outside the scope of a single
00:03:25.699 00:03:25.709 program but as with every single other
00:03:28.039 00:03:28.049 disruptive technology that human beings
00:03:30.050 00:03:30.060 have ever invented from The Telegraph
00:03:32.089 00:03:32.099 and the internal combustion engine in
00:03:34.220 00:03:34.230 the 19th century to renewable energies
00:03:36.710 00:03:36.720 and the Internet today there will always
00:03:38.899 00:03:38.909 be a body of opinion that extinct for
00:03:41.720 00:03:41.730 reasons not to continue with its
00:03:43.729 00:03:43.739 development and that's no bad thing in a
00:03:45.800 00:03:45.810 way it keeps the developers on their
00:03:47.270 00:03:47.280 toes and it probably does occasionally
00:03:49.069 00:03:49.079 weed out the really wacky ideas from the
00:03:52.099 00:03:52.109 mix in one sense here in Europe and
00:03:54.319 00:03:54.329 particularly in continental Europe that
00:03:56.599 00:03:56.609 fear of monopolistic centralized control
00:03:58.879 00:03:58.889 that I spoke about a moment ago is just
00:04:01.159 00:04:01.169 as prevalent as it is over there in the
00:04:03.259 00:04:03.269 United States over here though the
00:04:05.300 00:04:05.310 anxiety is all about Europe's heavy
00:04:07.460 00:04:07.470 reliance on Russian methane gas European
00:04:11.240 00:04:11.250 governments feel an acute sense of
00:04:12.800 00:04:12.810 vulnerability to the vagaries of mr.
00:04:14.780 00:04:14.790 Putin's regime as was so graphically
00:04:17.029 00:04:17.039 demonstrated when Russia's gas giant
00:04:19.129 00:04:19.139 Gazprom turned off Ukraine's gas supply
00:04:21.800 00:04:21.810 in the middle of the harsh 2018 winter
00:04:24.070 00:04:24.080 here in the UK our government policy
00:04:27.760 00:04:27.770 is guided by our very own climate change
00:04:29.980 00:04:29.990 Committee or CCC they're the people who
00:04:33.189 00:04:33.199 earlier this year recommended a pathway
00:04:34.809 00:04:34.819 by which the UK could reach net zero
00:04:37.059 00:04:37.069 carbon emissions by 2050 part of that
00:04:40.689 00:04:40.699 pathway would see the UK government
00:04:42.460 00:04:42.470 pushing ahead with the development of
00:04:44.439 00:04:44.449 hydrogen the committee's report made
00:04:46.570 00:04:46.580 these summary observations hydrogen is a
00:04:50.020 00:04:50.030 credible option to help decarbonize the
00:04:51.850 00:04:51.860 UK energy system but its role depends on
00:04:54.369 00:04:54.379 early government commitment and improved
00:04:56.649 00:04:56.659 support to develop the UK's industrial
00:04:59.140 00:04:59.150 capability hydrogen can make an
00:05:02.350 00:05:02.360 important contribution to long-term
00:05:04.230 00:05:04.240 decarbonisation if combined with greater
00:05:06.790 00:05:06.800 energy efficiency cheap low carbon power
00:05:09.460 00:05:09.470 generation electrified transport and new
00:05:12.790 00:05:12.800 hybrid heat pump systems which have been
00:05:15.309 00:05:15.319 successfully trialed in the UK hydrogen
00:05:18.700 00:05:18.710 could replace natural gas in parts of
00:05:21.010 00:05:21.020 the energy system where electrification
00:05:22.390 00:05:22.400 is not feasible or is prohibitively
00:05:25.029 00:05:25.039 expensive for example in providing heat
00:05:27.249 00:05:27.259 on cold winter days industrial heat
00:05:29.680 00:05:29.690 processes and backup power generation
00:05:32.249 00:05:32.259 but they also point out hydrogen is not
00:05:36.100 00:05:36.110 a silver bullet solution there's clearly
00:05:39.219 00:05:39.229 a great many potential opportunities
00:05:41.020 00:05:41.030 being pursued and developed with
00:05:42.640 00:05:42.650 hydrogen and again far too many for a
00:05:44.769 00:05:44.779 single program so in today's video we're
00:05:47.170 00:05:47.180 just going to focus on the part of that
00:05:48.790 00:05:48.800 climate change committee report that
00:05:50.740 00:05:50.750 talked about using hydrogen as part of a
00:05:53.589 00:05:53.599 hybrid system to heat our homes heating
00:05:56.860 00:05:56.870 homes businesses and industry accounts
00:05:59.559 00:05:59.569 for nearly half of all the energy use in
00:06:01.779 00:06:01.789 the UK and a third of UK carbon
00:06:04.390 00:06:04.400 emissions so reductions in this sector
00:06:06.550 00:06:06.560 will have a big influence on the UK's
00:06:08.800 00:06:08.810 chances of hitting the 2050 target the
00:06:12.189 00:06:12.199 CCC reckoned the cheapest scenario for
00:06:14.620 00:06:14.630 the UK's national heating in a
00:06:16.180 00:06:16.190 low-carbon world will be achieved by
00:06:18.580 00:06:18.590 installing hydrogen boilers in
00:06:21.040 00:06:21.050 conjunction with the electrification of
00:06:23.170 00:06:23.180 heating by which they mean a hybrid
00:06:25.209 00:06:25.219 heating system so what exactly is a
00:06:27.640 00:06:27.650 hybrid heating system well it's a system
00:06:30.580 00:06:30.590 that combines a heat pump outside the
00:06:33.159 00:06:33.169 house with some sort of boiler inside
00:06:35.950 00:06:35.960 the house there's two types of heat pump
00:06:38.170 00:06:38.180 air source heat pumps
00:06:40.390 00:06:40.400 ground-source heat pumps according to
00:06:42.249 00:06:42.259 this very useful report at possibly one
00:06:44.590 00:06:44.600 of the world's most geekly title
00:06:46.390 00:06:46.400 websites Euler guide co uk a ground
00:06:50.200 00:06:50.210 source heat pump extracts heat from
00:06:51.999 00:06:52.009 underground pipes are buried in your
00:06:53.890 00:06:53.900 garden either horizontally in loops or
00:06:55.719 00:06:55.729 vertically downwards a fluid passes
00:06:58.629 00:06:58.639 through these pipes which extracts heat
00:07:00.460 00:07:00.470 from the ground and transfers it to a
00:07:02.560 00:07:02.570 heat exchanger this heat exchanger heats
00:07:06.520 00:07:06.530 water via taps and central heating an
00:07:09.640 00:07:09.650 air-source heat pump is a fan unit which
00:07:12.580 00:07:12.590 has installed outside your home where it
00:07:14.200 00:07:14.210 extracts heat from the air outside even
00:07:16.210 00:07:16.220 in temperatures as low as minus 15 and
00:07:18.310 00:07:18.320 again this heat is used to heat water
00:07:20.650 00:07:20.660 via taps in your central heating the
00:07:23.140 00:07:23.150 other half of the hybrid system is the
00:07:24.460 00:07:24.470 kind of boiler that most of us are
00:07:25.900 00:07:25.910 already used to the boiler is at its
00:07:27.939 00:07:27.949 most effective and cheapest to run in
00:07:30.279 00:07:30.289 the cold winter months a hybrid heating
00:07:32.860 00:07:32.870 system will monitor the temperature
00:07:34.480 00:07:34.490 outside and automatically choose the
00:07:36.730 00:07:36.740 most energy-efficient option for example
00:07:38.890 00:07:38.900 when the temperature outside is 2
00:07:40.600 00:07:40.610 degrees Celsius or higher the heat pump
00:07:43.150 00:07:43.160 will heat your home and hot water using
00:07:45.610 00:07:45.620 renewable energy so your boiler doesn't
00:07:47.230 00:07:47.240 need to run when the temperature drops
00:07:49.360 00:07:49.370 the system will intelligently switch to
00:07:51.939 00:07:51.949 your boiler so as to maintain efficiency
00:07:53.980 00:07:53.990 and keep energy costs to a minimum in
00:07:57.339 00:07:57.349 fact the boiler could just use natural
00:07:58.689 00:07:58.699 gas like the ball is that most of us
00:08:00.370 00:08:00.380 have got in our homes now but of course
00:08:02.050 00:08:02.060 that wouldn't really contribute to our
00:08:03.730 00:08:03.740 net carbon zero targets would it it
00:08:06.159 00:08:06.169 could instead be an all-electric model
00:08:08.379 00:08:08.389 electric combi boilers already exist and
00:08:11.140 00:08:11.150 if they get their powerful renewable
00:08:12.820 00:08:12.830 energy either because you get your
00:08:14.409 00:08:14.419 electricity from a green energy provider
00:08:16.420 00:08:16.430 or you've got solar panels on your roof
00:08:18.610 00:08:18.620 or perhaps even a combination of both
00:08:20.260 00:08:20.270 then an electric boiler is a very good
00:08:23.080 00:08:23.090 low carbon alternative to our
00:08:24.580 00:08:24.590 traditional gas boilers in fact so far
00:08:27.700 00:08:27.710 in this scenario we haven't mentioned
00:08:28.839 00:08:28.849 hydrogen at all
00:08:30.040 00:08:30.050 so where does that fit in well as a
00:08:33.310 00:08:33.320 result of those climate change committee
00:08:35.199 00:08:35.209 recommendations that we looked at
00:08:36.490 00:08:36.500 earlier back in 2018 the UK government

00:08:49.840 00:08:49.850 the potential for domestic hydrogen
00:08:51.940 00:08:51.950 boilers as well as Hobbs
00:08:53.769 00:08:53.779 ovens and fires while the climate change
00:08:56.079 00:08:56.089 committee does accept the production and
00:08:58.090 00:08:58.100 use of hydrogen is generally less
00:09:00.129 00:09:00.139 efficient than electrification they also
00:09:02.530 00:09:02.540 point out the hydrogen is more readily
00:09:04.600 00:09:04.610 storable than electricity a very large
00:09:06.819 00:09:06.829 scale which is why the UK and other
00:09:09.369 00:09:09.379 European governments are quite keen to
00:09:10.869 00:09:10.879 use it to replace natural gas and
00:09:13.389 00:09:13.399 potentially oil in parts of the energy
00:09:15.670 00:09:15.680 system we're full electrification is
00:09:17.559 00:09:17.569 very difficult or disruptive or very
00:09:20.470 00:09:20.480 expensive so how do hydrogen boilers
00:09:23.739 00:09:23.749 work then well that's a very good
00:09:25.389 00:09:25.399 question because they're not actually
00:09:26.860 00:09:26.870 commercially available just yet that's
00:09:28.809 00:09:28.819 where the report from the Fraser Nash
00:09:30.489 00:09:30.499 consultancy comes in they looked at
00:09:32.590 00:09:32.600 three likely options for development
00:09:34.540 00:09:34.550 number one was new appliances developed
00:09:36.850 00:09:36.860 specifically to run on hydrogen number
00:09:39.340 00:09:39.350 two was the adaptation of existing
00:09:40.720 00:09:40.730 natural gas appliances in situ to run on
00:09:44.049 00:09:44.059 hydrogen and number three was new dual
00:09:46.900 00:09:46.910 fuel appliances that can switch from
00:09:49.210 00:09:49.220 natural gas to hydrogen and they've
00:09:52.179 00:09:52.189 actually identified some fairly
00:09:53.530 00:09:53.540 significant technical challenges that
00:09:55.809 00:09:55.819 we'll need quite a lot of research and
00:09:57.400 00:09:57.410 development to overcome in very very
00:10:00.639 00:10:00.649 brief summary of their very large report
00:10:02.949 00:10:02.959 they made these final conclusions
00:10:06.210 00:10:06.220 hydrogen has a significantly higher
00:10:08.470 00:10:08.480 flame speed greater flammability range
00:10:10.780 00:10:10.790 and is likely to burn as a higher
00:10:12.879 00:10:12.889 temperature than natural gas these
00:10:15.610 00:10:15.620 characteristics present significant
00:10:17.379 00:10:17.389 engineering challenges that particularly
00:10:18.999 00:10:19.009 affect the burners in appliances
00:10:21.449 00:10:21.459 specifically there are concerns with
00:10:23.470 00:10:23.480 light back which is propagation of
00:10:25.210 00:10:25.220 flames back through burners higher NOx
00:10:27.639 00:10:27.649 emissions and the potential explosion of
00:10:30.460 00:10:30.470 unburned gas yeah they need to sort that
00:10:33.040 00:10:33.050 one out the report also talked about
00:10:35.590 00:10:35.600 flame failure devices and these things
00:10:38.319 00:10:38.329 detect the presence of a flame and
00:10:40.150 00:10:40.160 automatically switch the gas off if the
00:10:42.519 00:10:42.529 flame goes out natural gas boilers use
00:10:45.369 00:10:45.379 ionization sensors to detect combustion
00:10:47.949 00:10:47.959 gases from the flames the ionization
00:10:50.379 00:10:50.389 sensors don't work with a hydrogen flame
00:10:52.329 00:10:52.339 so you need something else industrial
00:10:55.119 00:10:55.129 processes use ultraviolet and infrared
00:10:57.100 00:10:57.110 sensors they're a good option but
00:10:59.829 00:10:59.839 they'll have to be redeveloped to reduce
00:11:01.660 00:11:01.670 their size and cost other components
00:11:04.449 00:11:04.459 like pipelines gas valves and heat
00:11:06.519 00:11:06.529 exchangers
00:11:07.420 00:11:07.430 we'll need a certain amount of
00:11:08.560 00:11:08.570 redevelopment to cope with the different
00:11:10.510 00:11:10.520 combustion characteristics of hydrogen
00:11:12.340 00:11:12.350 but essentially the fundamental
00:11:14.650 00:11:14.660 operating principles won't fundamentally
00:11:17.050 00:11:17.060 change perhaps their most important
00:11:19.540 00:11:19.550 piece of advice though is this
00:11:21.510 00:11:21.520 development of a hundred percent
00:11:23.170 00:11:23.180 hydrogen domestic appliances will
00:11:25.690 00:11:25.700 require government intervention
00:11:27.240 00:11:27.250 initially this requires target funding
00:11:30.190 00:11:30.200 to close the innovation gap and develop
00:11:32.560 00:11:32.570 the first generation of appliances in
00:11:34.870 00:11:34.880 other words some central government
00:11:36.550 00:11:36.560 finance paid for out of our taxes will
00:11:39.070 00:11:39.080 have to be diverted from other funding
00:11:41.080 00:11:41.090 programs into the research and
00:11:42.940 00:11:42.950 development and quite possibly
00:11:43.900 00:11:43.910 subsidization of these new technologies
00:11:46.990 00:11:47.000 the climate change committee themselves
00:11:49.690 00:11:49.700 even went as far as saying this
00:11:51.450 00:11:51.460 depending on the development of hydrogen
00:11:53.620 00:11:53.630 ready appliances and the cost premium
00:11:55.660 00:11:55.670 over natural gas boilers but government
00:11:57.820 00:11:57.830 should consider mandating hydrogen ready
00:11:59.860 00:11:59.870 heating appliances by the mid-2020s
00:12:02.220 00:12:02.230 similar to the successful manned ation
00:12:04.600 00:12:04.610 of condensing boilers 20 years earlier
00:12:07.090 00:12:07.100 and that's a concept that might be more
00:12:09.430 00:12:09.440 readily acceptable over here in Europe
00:12:11.500 00:12:11.510 than it would be in some other societies
00:12:13.510 00:12:13.520 around the world not least in the United
00:12:15.610 00:12:15.620 States and then there's still the issue
00:12:17.410 00:12:17.420 of how the hydrogen is produced in the
00:12:19.420 00:12:19.430 first place as this CCC infographic
00:12:22.780 00:12:22.790 shows it won't just be via a water
00:12:24.670 00:12:24.680 electrolysis the intention is still to
00:12:27.130 00:12:27.140 use steam reforming as well but with the
00:12:29.290 00:12:29.300 important addition of carbon capture and
00:12:31.780 00:12:31.790 storage and that's a whole separate
00:12:34.000 00:12:34.010 technology and debate that we've looked
00:12:36.040 00:12:36.050 at a couple of times in previous
00:12:37.570 00:12:37.580 programs so I won't dwell on it here
00:12:39.580 00:12:39.590 suffice to say that for various reasons
00:12:42.520 00:12:42.530 the jury is very much still out on
00:12:44.680 00:12:44.690 whether carbon capture and storage is a
00:12:47.260 00:12:47.270 viable option within the carbon
00:12:49.150 00:12:49.160 reduction project no doubt many of you
00:12:51.610 00:12:51.620 will have a view on this subject and
00:12:52.900 00:12:52.910 have been some great debates in the
00:12:54.160 00:12:54.170 discussion threads on the previous video
00:12:56.020 00:12:56.030 so please do feel free to dive in and
00:12:58.180 00:12:58.190 leave your thoughts in the comment
00:12:59.830 00:12:59.840 section below we could go into loads
00:13:02.230 00:13:02.240 more really technical detail on this one
00:13:04.090 00:13:04.100 but in the interest of brevity and
00:13:05.530 00:13:05.540 sanity I'll leave it there for this week
