a carbon neutral world to run on clean energy. but there is still a long way to go. climate change as a care what the markets think, the science will that still say we must have global greenhouse gas emissions by 2030. if we're to have any hope of reaching that 0 by 2050, and avoiding the worst effects of global warming. so the change while it is happening, needs to happen quicker in this program will be look at 2 of the solutions that have a part to play in that transformation on the, on the islands in the u. k. site as the working with one a clean energy is holy, grails, green, hydrogen, and in norway, a carbon neutral data center is using the force of nature to power our digital lives. the global demand for energy is increasing, but burning fossil fuels is polluting and it's warming the planet with devastating impact for life on earth. while renewable energy from wind, sun, and c,

to the never less intermittent is difficult to store. for a few of the future is emerging, which could prove fundamental to de carbonite in the global economy. i've come to the orkney islands of the north coast of the u. k, where a network of sizes and researchers approving that are missing linked in the next renewable energy revolution might be found in the simplest and most abundant element. hydrogen, the universe is about 73 percent hydrogen, mainly occurring as gas, but on earth, most hydrogen is contained in water. is the h in h 20. after it's generated from water, it can be used as a few a poet coz, buses and even spacecraft. but in order to extract it from water, you need electricity. when that's produced using fossil fuels, it contributes to greenhouse gas emission. in orkney, known as the energy islands,

scientists have discovered how to produce green hydrogen using renewable power, generated by wind farms and tidal turbines. it could be a game changer, a meeting, a del lydia deal, who's a hydrogen project manager and was brought up on orkney. just letting an island we have a sense of self sufficient fee. we need to do thanks for our fail to practice. we are not really good stuff's brazilian, as an island. mean we come to shop and say when a board, these 13 inhabited islands to see how they produce hydrogen. it's kind of a juxtaposition of small, quiet island, quite a high energy project. this turbine is owned by local residents and produces more energy than the local grid can handle. so the excess power is used in hydrogen production. i'm no scientist, but i could see on that that the same it says in explosive,

compress gas. and what is actually happening behind this, this fits what's going on in these boxes. so if a working energy production site, which is why we're founding our site, what's the connection between wind that hydrogen? we have the wind turbine going round here today m. when it reaches a 1000 meters per 2nd, we switch that energy production over to produce hydrogen. these metal boxes contain the key piece of machinery and electrolyzer that generates hydrogen gas. and electric current flows through the electrolyzer causing water to break down into hydrogen and oxygen. hydrogen is then collected and compressed, so the electrolyzer just takes normal drinking or it use of energy from the wind turbine. it splits the h 2 o 4 and to hydrogen and oxygen. we capture the hydrogen for use for energy and the oxygen at the moment. it's just a tough spear, so your re diverting? yes. that wind energy into hydro dot. right? yeah. as storing and storing high can it's transported by trailer and used all over

orkney, some in domestic heating but mostly in commercial vehicles and ferries. in the trailers, the hydrogen stored under pressure at $184.00 times its original density. that's a lot of energy. a meeting with james ferguson, a specialist in hydrogen storage. the highly inflammable gas is locked away in compounds and the key site. oh wow. oh gosh, so one of the big advantages of hydrogen is that it is a kind of option for seasonal energy storage. and that's when we want to store a lot of energy over months. so we know that in the u. k, during the winter is very low, it's very windy if we go to a wind turbine based energy system. we're going to have a lot more generated in the winter than we need. and so we can capture that and store it from the form of hydrogen, and then keep it until the summer when we don't have any wind blowing and, but we're still using energy the meg was. so how is hydrogen used as a fuel where?

well, james has a rather knotty way of demonstrating this with a toy car that looks about what that's about 20, you know what? it shows me how to produce hydrogen with many electrolytes. so we just wait a moment, we're going to generate some hydrogen. we're going to build up an electric current passing through the water forms hydrogen bubble. now got some gas storage here that we didn't have before. now i'm going to take my cable round here and you can see now that the gases are flowing into the fuel cell. and then that is going to allow us to be with the fargo that is absolutely better. the principal, to pose the fuel cell in james is toy car is the same when scaled up to power of fleet fight council ban on the island. well, completely silent, completely silent. wow. you can sometimes hear the compressor from the hydrogen

when it's when it kicks in. it, you know, here we, well, that's all you know here. david hannon is working with the council to expand its use of hydrogen technology. so for a long time, we're talking about electric vehicles as being the future of, of green transportation. what do you get a hydrogen per vehicle that you wouldn't get of an electric vehicle? this is also about 3 runs off the battery. but then the hydrogen is yours to extend the range on it. so if you're either traveling long distances, you can potentially double lot range and is another advantage. it's quick to re fuel with electrons battery. you might take from half an r to it ours to charge your battery, whereas this is pretty much instantaneous. you know, talking couple of minutes normally we'd expect to see an exhaust pick that the back of eventually this. yeah. and you can see there's no exhaust here, i mean same as any other electric vehicle. obviously we've got hydrogen,

but then the sort of emissions off out as water paper is here yet. right? wow. all right, really? i whispered me. it's great to hear. house seems to be growing all the time and there's that awareness of the importance of this kind of network or this ecology of energy when you live in an archipelago. another important form of transport is very nice. very company operates $74.00 different connections and they are more than $20000.00 sailings each year. but the fuel used in shipping by the polluting. i david for david, hidden who works with the fay, company clean hydrogen is part of this plan to clean up the operation. and they all happens below deck. ok. have no idea what we get into it. here we go. oh wow.

those are the shit. what we looking at in the cylinders contain 5 kilos of hydrogen us equivalent 20 leadership fuel. what are you using this hydrogen? hydrogen is still in the system. it will run on july, january and it's only the engine price steering the safety systems and the delays and anything in the navy. and so do you see a time when in the future hydrogen will be used to drive all the ships. operation systems, including proposed within 2 will be stopping obviously on the small scale shipping. but the states are already established fans and ferries powered by green hydrogen just part of the picture in orkney. pioneering research into how the fuel could play a global role in transport. and beyond is happening here at the orkney research and innovation campus. one of the most important projects is in aviation.

in a normal year, nearly $14000000.00 flights world wage result in heavy c o. 2 emissions search for an alternative fuel. he's virgin one company collaborating with scientists in orkney is cyril avia. i contact director surrogate kids a live excited about their 1st 15 minute long hydrogen test flight. it was a combination of almost 3 years of research and that frankly, it was, it was as the for delivering the baby and the full g was so relieved. then the so excited that the same time i know that you guys are planning to fly here with one of your hydrogen per playing. oh, the final flight down our high fire one project. i think in place. i'm fortunate there or can you is famous for it's hydrogen. can you give us

a time scale when you think that we will see passenger planes in the sky running on hydrogen? of course they're the technologies in its infancy. but i personally believe that in about 15 to 20 years, there will be a lot of jets. why i'm using hydrogen. and this is truly exciting. so if we can arise through the challenges of our energy economy or future transportation needs, it means embracing a range of solutions. i think what they're doing here orkney is proving the green hydrogen can be pot. fiance, green hydrogen is beginning to take home. it's a key part of the ease plants become the world's 1st carbon neutral constant by 2050. a new projects have been developed in chile, saudi arabia, united states. yes, there is still a way to go before green. hydrogen is proven to be scalable and cost effective, but it is gaining traction. and it's one of a number of current trends that harold

a welds free of fossil fuels. there is definitely a new power system and a new energy, a system emerged. kind of our eyes, whether we look at power, generation and distribution or whether we look at transport. there is no doubt that we are in the middle. all the most consequential transition in the energy space that we have seen in the 100 years. it is a very exciting moment. it's also a nerve wracking moment, because we know that if we don't get to half emissions by 2030, it will be too late to do anything substantial about climate change. this is our last window of opportunity to bend the curve of emissions and get on to a diff and track and doing society would be a society that has

a 100 percent clean energy. that energy would be decentralized, cheap, ubiquitous. we would be able to provide power to every single home on this planet. we currently have 800000000 people who do not have access to power, meaning they're in abject poverty. by moving over to a 100 percent clean energy decentralized, we can make energy ubiquitous, and we can bring those work under the line of poverty over that line. a green society would be an economy that has smart grids that has storage available to all renewable energy generation. sources would also beat society in which there is efficient and clean transport. passenger vehicles would offer transport as the service not being a possession of any individual. and heavy transport would be using clean fuels.

and finally, cities would be clean wyatt because we would have put the internal combustion engine into them. and cities would be organized into smaller communities, around food and energy. at the beginning of the most decisive decade in the history of human kind. it behooves all of us to understand that this has been challenging and will continue to be challenging. but we can do that. we can address climate change in a timely fashion. we can avert the worst disasters of climate change, and in so doing, we can bring a much better quality of life for all citizens of this planet. and certainly for the ecosystems upon which we depend

ah, people across the planet are spending an increasing amount of time on line from work meetings and catching up with friends to movies, streaming, and shopping. we are now more reliant than ever on platforms which generates and store data. but this data doesn't just vanish into thin air. it comes at a very real environmental cost. everything we do on line passes through data centers which consume huge amounts of entity and emit nearly as much c o 2 as the airline industry. i'm in no way to see how one center is harnessing the energy of these fuel worth to stole our digital information without a heavy carbon footprint. but this is a famous tourist attraction and photo hotspot poke is stolen in no way. it draws hundreds of thousands of visitors every year, but i'm curious to find out what people know about the data,

all these photos generate. so when you take a selfie, it lands somewhere, have you ever imagine where that could be? i think the 1st time i would imagine is my, when you're asking, i haven't been thinking about it. no, i have no idea. i send it to google, i guess in the cloud, in the cloud. and do you know what the cloud is? it makes a storage place like myself, most people only have vague ideas of where all our data has kept. i've come to university of savannah to meet an expert on data storage and find out where our selfie send up. the photo is. so ruby saw in the memory of their phone and then if you'll share the photo or you want to back up the photo into the cloud area and up in some data center, remotely could be in europe. it could be also in

a remote sign across the atlantic at those they probably accumulated in those data center. and those wallkill are forced us to have a big a big data center. so burn, bear our problem for sustainability or how long or how much data we have to store them. in recent years, many of us have been moving into the digital realm and even more so under the cove at 19 pandemic for you here for the city. so live our online habits, take a heavy toll on the environment. a typical search which passes through data centers processing and storing information requires as much entity as illuminating as 60 what light bulb for 17 seconds. that doesn't sound like much until you realize google alone process is 3500000000 searches a day. around one percent of electricity globally is consumed by data centers,

many of which provide promote storage facilities or what is also known as the cloud . is estimated that in 10 years is our data network grows. almost 70 percent of all electricity will be used just to power and qu huge service, preserving everything from billions of family photos to big data on space travel. so where and how you stole your data can make all the difference. and no way is ahead of the game on this, since it's powered nearly a 100 percent by renewable energy, most of which comes from hydro power. i'm on my way to lancaster and island near savannah. i've heard they have an old military storage, but instead of storing to dose and wall hits, they now stole billions of bites of information from all over the world. the underground green mountain data center which opened in 2013 is cop and neutral. it's run on high to power from water, rest of us up the mountains for question. nice to meet you. nice to meet you as

well. ah. oh, wow. this is like being in a james bond film, but i can see that this is very secure. this is very secure. oh wow, thank you. so this is how it looks when we took over the to sites here is empty space, but it will not be empty forever. as soon as we grow, this will be a data center as well. so no, we're en freight. what people refer to as the cloud. this is where our customers are running their server storage equipment. so what kind of information if don't hear it could be anything from storage or picture to national critical

infrastructure if you'd be kids at home doing their lecture online. so many people when they think about the cloud, they think out in the open as i think white and fluffy. but actually the cloud is mechanic and in black and it's noisy, it's black and it's noisy, and it consumes a lot of power and generates a lot of heat to see how the center manager says it's a quick write down the corridor. oh, we're the in diffuse room. this is for all the green and the d flows through into the data. so this is basically the giant engine of this data center. the consumption in this data center with all the different data holes and consumes the power equal to about 20000 households. while this may seem a lot,

some of the biggest data centers, consumers, much power. as the city of a 1000000 people, every click you do on your device, generates activity inside a data central summer. if it's in norway is green and renewable as well. so using green energy, this data center is reducing its impact on the environment by cooling it service, choosing cold water from the near by deep salt water inlet of yours. so while most data centers use around 40 percent of their energy to cool servers, which would otherwise reach a 100 degrees celsius in minutes, this data center gets its cooling free from nature. so this is where we're producing the cold water used to cool the cloud inside a mold, cold sea water from the fuel it into the base. and next to the data center,

this water, which is constantly 8 degrees celsius, is then pumped up through the heat exchanger cooling down, separate water pipes that circulate through the data center. the won't up cbo to then exits back into the fuel at around 20 degrees celsius. wet quickly cools down again. the green mountain data center in no way is unique because of the fuel cooling the service. and the way in which they've repurposed an old site. but all over scandinavia tech giants like facebook, google and microsoft are building huge data centers running on hydro and wind power . in fact, investment in nordic data centers is set to double by 2025. 0, thank you. our yes, please vote fully electric. i'm meeting siri, kelvin, a local, mitre, ologist, and green, and vista was confident this trend will continue to this is where the hydro power is. yes, the old, the flu lay a hydro station. it's actually the world's longest 4440 for

that. over 100 years old. so be careful though i, i can see that its own from this old train here. here you see the old pipe coming down from the mountain. so all the water's just flowing high speed in the pi, creating electricity when they hit the turbine. so you have to use for nature gives us. so in norway we have incredible rain or the concrete have sun. yeah, we also have wind, but here it's rain that gives us the electricity. scandinavia will be important to the world's data storage. i think scandinavia will be very important for future data storage. it's called climate. if you can use the cold for your to, to cool down the data center, we have the hydro poll were to run data centers. however,

i think we also need to be even more responsible and take action that each one of us. and for instance, if we are talking on both data storage, we need to be concerned about how many celsius we need to take home many emails, some snaps and text message. we need to send me though we can't see it. our use of digital devices has an impact on the world around us. this is only set to grow. nearly 60 percent of the wealth population is already online and around $1000000.00 new uses sign up each day. as our reliance and data expands, we need to find greenway to manage it. here in no way, i've seen how this can be done. and i really need to learn from examples like this and make sure that we balance our modern lives with what the planet can sustain in which so many of us stuck a time during the panoramic brain. perhaps hard to see that the world really has

been given a golden opportunity for green recovery commitments are happening all over the place as nations businesses, cities, investors pledge 0 common targets by 2015. but right now 21st is the q year. that's just under a decade to determine the feature of the planets around the world. we're already seeing glimpses the green society that could be hours last year. renewables overtook fossil fuels as the main source of electricity in europe, and new k and australia, to the solar panels on rooftops of one in 4 highway the nor was that solar complex in morocco, turbulence 1st phase, and it's already producing enough energy to power the city of marrakech twice over a 60 percent of mount because cells in norway are electric, diesel cars will be banned there in 2025. the solutions are already there. it does need to go global to make a real difference. and for us to have that chance at
