in the, on the real media much now on youtube the what would you like to be like without steal, fixing caused airplane, wind, turbines, and countless other things. there's a problem that the heat involved so far, the highest melting temperatures necessary can only be reached with the help of fossil fuels. now a switch team wants to tap the most sustainable. so that's that's a move from the well, the for such on dw sign shift. welcome to tomorrow. today the producing steel requires temperatures of over $1500.00 degrees celsius,
2:31 am
burning oil and gas. so, so far been the only way to reach them. but now, and alternative technology is under development at this with university f. l. sophia, how soon are is convinced solar energy can provide heat for the steel industry in the future? she's designed to parabolic reflect there for capturing and concentrating sunlight to do so 9. 0, i don't know if it's just, i'd say the potential is huge because there are not many alternatives for producing high temperature heat from renewable sources. decisive factor is that going solar would help the industry save c o 2. a lot of it to be precise. around 7 and a half giga tons of the gas annually. that's how much is released when producing heat for industrial processes. it's around 30 percent of all industrial c o 2 emissions worldwide. and a swiss model flight is collected by
2:32 am
a parabolic reflector and the sun's rays are concentrated 1000 phone to produce steel thousands of mirrors. what have to work in concert to collect and concentrate enough light, which would be directed into a heat absorbing material. the heated material would then be fed into the steelworks to drive the blast furnace. a facility like that doesn't exist the mirror or raise like that do for the temperatures and necessary to power small steelworks. you need a field of mirrors the size of for football pictures. but there might be ways to massively reduce the amount of space needed engineer, i mean the yano cosigned to has developed what's called a thermal trap. it's a little more than a cylinder of chords. here we have our at thermo top setup. we have these uh parts around 30 centimeter of, of solid parts. concentrated sunlight,
2:33 am
computer illustrated by a spotlight is fed directly into the thermal trap passing on the end or through the cords. at the other end of the trap, the light strikes the heat absorbing material. the absorber, it tries to release this energy, but the cords prevents the heat from escaping again. the absorber material grows hotter and hotter. it can quickly reach temperatures over 1000 degrees celsius. thermal traps could be easily integrated into existing mirrors. system says emiliano casado doubling their heat yield. there's no reason you can't make larger versions of this small prototype for industry. how much thermal energy will you deliver is just the mother of k. so you can do these 1000 times larger than when he
2:34 am
got 1000 pounds more that or even more managing. ringback interesting for the steel industry, which is currently looking for cost effective and sustainable alternatives to oil and gas. could thermal traps make the change over economically viable? when it hits things on our end, if you want to bring new solar energy sources online, you would have to rework these processes and make investment license. so you would definitely have to calculate 5 to 10 years to sponsorship. for the space in the auto ration would some places be more suitable for solar power blast furnaces than others? some morning did he not his own on the desert. you can harvest maybe 3 or 4 times more energy. that means beats along this hall. that's why we'll certainly want to produce a lot in countries where there's
2:35 am
a lot of solar energy. and even if the sun does shine less in europe than in arizona, solver heat could one day help make c o 2 free steel production or reality there as well. the spoiler where that's not everything that's possible in scientific times can be implemented successfully and sustained for example, capturing the greenhouse gas c o 2 for storage, some went on to ground. the idea behind the technology is to slow down climate change that making it work is proving, but it's expensive and energy intensive. remember, the early 2000 concept low phones were breaks and green day was having a moment. but if you're a climate scientists, you're probably focused on a different hop topic, carbon capture in storage. so basically capturing c o 2 from a plant, the principal fulfills and bearing an underground technology promised to become key
2:36 am
and fighting climate change. the most effective way to help ober to meet it's emission reduction goals. now the world has changed a lot and the last 20 years. but cps is still not the widespread. they have failed to meet the promise, probably seen in terms of the comb to tail the quality of what they during ccs or carbon capture and storage. fucks up a portion of this youtube released at a fossil fuel plan. then companies can transport that to, to elsewhere, to store it away by injecting it into rocks into the c bed or into old world fuels, which ironically helps extract more oil. but more on that later, this technology has been used for a few decades now. but there's also a 2nd option direct or capture or dec, which in comparison a full baby tech here. giant fans suck in air and pass it through a filter or through chemicals to trap c o 2 particles. these can be collected and stored underground. so basically
2:37 am
a target c o 2 that's already in the atmosphere. top climate experts agree, but capturing carbon directly from smokestacks and removing it from the app just here is essential to help us become climate neutral by 2050. the we're a severely lagging behind. these technologies are only capturing 0 point one percent of our global emissions. meaning we're playing a massive game of catch up in the ninety's and securely in the of the $600.00 sentence. that was an awful lot of promising a fact calvin capture and storage that was in price price also fuel jump then use. it was seen as is the way to, to square our emissions targets and, but to go on for anything. and the international energy agencies road map up the times. the goal was to have $100.00 carbon capture and storage projects. operational by 2020. now, 4 years after this deadline, we have just over 40 commercial 50 s plants. we're not even halfway there. and was
2:38 am
some of these projects are held at a successes the list of failures as much longer to been assessed and full of full scale plants, doped and using success and most of which are subsequently shut down because i know financially viable more than 3 quarters of large scale projects initiated between 19952018 were called off or put on hold. that's according to a 2021 study. in the early 2006 dictation was that it was going to get cheaper. so technology got better and was scaled up. now the owners of carbon capture facilities are not very generous and sharing the information about how well live projects do or how expensive it is to capture c o 2. what's happened over time is there is no evidence. the cost of carbon capture has gone down. it's pretty hard to pinpoint what exactly the price of capturing carbon is. the range is pretty big because it depends on the nature of the project and what
2:39 am
the source of emission says. but it's about 15 to a $120.00 per metric ton that is captured just for reference, a ton of through to is one passenger and it's on a flight from new york to paris. so multiply the price by the billions of tons we will have to capture for this tech to be effective. one way technology is good, cheaper is to scale them, but that's really hard. we'll see cs plants which have complex designs that need to be customized. that's because there are a lot of variables. what type of fossil fuel plant is that? where is the c o 2 going to be stored? our company is going to get into that storage side. they can just be mass produced cookie cutter style promise of c c. s allowed the upper right is of the developers of fossil fuel power stations. to say it's fine. we can go ahead with a scenario because we will be able to retrofit this technology on. so 30 a plant and come to emissions in 5 or 10 or 15 years time. according to the research organization, bloomberg n e s 6 oral has actually been tipping away from investing into renewables.
2:40 am
increasingly putting their money into solutions that keep their current business model viable, like carbon capture and storage. exxon mobil for example, is going all in on that route and fully ignoring renewables. another thing about capturing carbon is that it's very often used to, well extract more oil. the majority of cs plants pump the sue to they trapped into aging fuel 6 track leftovers. because oil is really stuck in fixed. so when you try to pump it out of a reservoir, a lot of it gets left behind. one way to get it out is to flush the field with c o 2, which works kind of like a lubricant. it makes you own more liquid and increases the pressure to get the crude out of the rock. this procedure is called enhanced world recovery and 70 percent of 60. as plants use it, the positive is it can be a carbon capture more profitable, but it also means more oil to new oil is either used as a feedstock in
2:41 am
a refinery or it's burned. and then what happens? it creates more c o 2. it's a cycle that keeps the oil and gas industry alive and profitable. okay, that was a lot of success, but there's another form of carbon capture that's getting more and more attention directly or capture. there are only 4 large scale dark plants around the world and 2 of them in iceland. that's also where the largest facility of climb works. ma'am of plant has the capacity to suck up to 36000 tons of c o. 2 out of the apples here over here in the grand scheme of things, that's a minuscule amount of the more than 37000000000 tons we met from fossil fuels in a year. but it's also just the beginning when we get to see the peak off of the prophecies that the direct tech capture. if we're able to expand direct to air capture, it could help us target past emissions. but there's a big bottleneck when it comes to scaling back the cost. if your thoughts,
2:42 am
you see it, so is expensive. the price to capture a ton of c o 2 from the apples here is much higher. one ballpark figure is that it costs around $500.00 to $700.00. energy is one of our biggest cost drivers. what many people don't know is that future is actually very time to, to, to know it here. so that means you have to move a lot of air to get to one ton of c o 2 climb works announced a new technology that itself is a breakthrough and efficiency. whether it's new filters that will capture more than double the seo to the previous ones that should have the costs by 2030. but even then it's still high at $250.00 to $350.00. i think it's only natural for humans to move the goal posts. if the price has to be in becomes more urgent. right. how do we measure the important stuff? i was the viper in the end, in terms of money. another open question with direct air capture is what happens when some c o 2 is captured. the plastic line works as running already inject the c o 2 into best old trucks or volcanic rocks and the company says it will not engage
2:43 am
and enhanced oil recovery. the problem comes with the way they are promised. the truth of the matter, as we already had last year, promises around c c s many years later big or is still cheer leading for it at a scale that ignores that technology is shaky track record. now we're seeing many companies, lots of direct air capture, but this cannot become another wave of inflated goals. so keep business running as usual. it's simply cheaper to avoid a ton of future today than to take it out of the see it. otherwise, 20 years from now, we'll look back to today and realize we over promised once again. hurricane heat waves must've rain. human induced climate change has exacerbated extreme weather events in recent years. at the end of october 2024, over 200 people died following stats in spain. while in germany, horses rose to disastrous levels in the river valley in 2021 research teams. that right now, monitoring how well it's ecosystems are recovering the our river valley one
2:44 am
slips like this. a changing natural landscape home to many different plant and animal species. then floods in july of 2021, severely damaged the eco system. here this team of 4 young scientists visits the river regularly. they're all part of a project involving universities in the german cities of p, a and copeland's the researchers are studying the bed of the are the aquatic organisms living in and on it say a lot about how well the eco system is recovering from the flood. and its aftermath, the pulling, i'm 0, someone can we gather samples with what's called kicked sam, blank cassette in the plant, the scoop and add in a relatively stable position in the ground. then stomp on the bed really hard for
2:45 am
a while. all the animals which live mainly on in or under the stones are swept up and that's where the current and the water comes in handy. it's pushes them right into the now the screws. the team usually catches small invertebrates, like worms, snails and insects larva before the flood d r was known for its rich biodiversity, the, the next now. so immediately after the flooded collapse completely, many species disappeared in bio diversity hasn't bounced back slowly. we're not seeing that yet. but that's what this project is about, monitoring how things develop to find out which habitats are recovering and how well the teen take samples and a number of points in the river. they also monitor water quality, which is closely linked to the wellbeing of the rivers phone, a nutrients that promote the growth of algae or one parameter.
2:46 am
they leaked from waste water systems heavily damaged by the flooding that our country did waste water was discharged into the river and that waste water contains a lot of nutrients. we now want to investigate in more detail how things will develop over the next few years. the of those investigations are carried out and allowed that the university of cobra ends here. the team calculates levels of compounds like phosphates, nitrates and ammonium. if a water sample turns dark blue, it contains to many of them. the project is scheduled to run for 6 years and is meant to provide scientific support for any restoration measures. but it's still early days. the team head to the river every 2 weeks to check its water quality.
2:47 am
any changes or the registered quickly by stephen, for example, winter's works are dug out to build a new bridge that can quickly clown to one or or set free nutrients or pollutants that may have accumulated tear during the flood on the lara tom. and then the work release is and mobilizes them again. that high levels of nutrients can harm aquatic life forms. because when lots of algae grows and subsequently decomposes oxygen and water levels drop. and that has consequences for the animals that inhabit the river. in a lab, it's a 2 year university of applied sciences. the young researchers therefore, also analyze how many invertebrate micro organisms are found in the samples. under the microscope, the team's sorts the animals into different groups and determine species like this
2:48 am
may fly larva as an individual species are highly adapted to their environment. this means that when we find certain species that indicates particularly good water quality, for example, because they need oxygen, bridgewater, that's why she called the initial results show that some species are already re populating the, are in the future. recommendations will also be made on how recovery and conservation efforts can best be streamlined at the optimized with one on, on other extreme weather events. dividing the project also, it looks at construction work from a biological and ecological perspective. this means for instance, that if the weather turns very dry in the future plan should incorporate a residual channel where water always flows where species that depend on water could survive. so i'm going to use an invalid and conservation plans for other
2:49 am
rivers will also benefit from the findings on the r the ticket routes. how wessa works exactly, and full cost it accurately. we rely on such a nights. what influence, for instance, do clowns have on cooling all roaming processes in the atmosphere? in june 2020 for a new e. so set to night was launched to help provide deeper insights into climate change . the, this is just after 1 in the morning and the so control room and tom stopped. the tension rises. it looks like we have a signal that sign into a service stablished contact with their satellite, successfully mastering another critical phase of today's launch. firstcare is up and rolling the dice on the floor so far. thank goodness we're really relieved
2:50 am
because it doesn't always happen at 1st contact and it can take several lower bits . so it was perfect. perfect. the 1st is critical moment, had come and gone just under an hour earlier when the space x falcon 9 rocket carrying the earth observation, satellite launched in vandenberg, california. everyone involved was holding their breath on take off 1st care tips. the scales at around 2 tons and is equipped with 4 state of the art instruments. became of the cooperative mission between isa and the japanese space agency jacks is to the site for a toughness buick interactions. climate and whether on our planet are primarily driven by solar radiation. however, it's distributed very differently in the atmosphere and interacts with both the water vapor and solid particles. they play a central role in climate research. some of the unprecedented is the combination of
2:51 am
instruments on a single satellite. they let us observe clouds and aerosols, along with the interactions with radiation coming from the earth and from the sun, all at the same time comes i to dismiss them cuz or over the next few years. first, carol will observe our planet from an altitude of 393 kilometers it's instruments. we'll send out light pulses and analyze the reflected signals. among other things, the researchers want to use the required data to create a 3 d model of the atmosphere and unprecedented detail. one bigger goal is to improve climate and whether models, the experts, hope that in the future or as care data will help them better forecast storms, floods or in pending droughts. a new era and observation. as the meeting is using existing techniques, for example, with optical sensors, you observe clouds and see which types they are. the new thing about the japanese cloud radar is that you can look inside cloud. so recognize things like vertical
2:52 am
movements. and for instance, whether it's raining or snowing ice, what's actually happening in the cloud to things you just can't see, otherwise, you couldn't do that before. and it's unique, an instrument like this has never flown before. the mission is costing europe and around 800000000 euro as while 52000000 is being shipped in by japan. he says, director general says the cooperation sends an important signal about remaining competitive in space. that's what up to suicide. the public money spent in europe, there's a fraction of that spent in the us or china for example. you know, we have to make sure we don't fall behind and are knocked out of the race. that's what we're currently discussing with member of countries. yes, that'd be to it's would be defended. this could be a 3. it's no early days for the mission. over the next 6 months, the researchers will test everything repeatedly and only then what parts care operations to be viewed as routine. but it's already says,
2:53 am
largest and most complex 1st observation mission today, designed to help us better understand how our world works. let us read the you have a question for us science to send it to us as a video, text or voice mail. if we don't see your query on the show, you'll receive a little surprise as a sign key. so go on just task. this time of view, a question comes from wayne k in the us, the how do we know there are other star systems? and are they like ours? our solar system is just one of the countless others in the universe. more than 4000 planetary systems have already been discovered in our galaxy alone. most store so far away the telescopes can see the stars directly,
2:54 am
but not the planets. so how do we know there? there are many were detected using what's called the transit method, which can be illustrated by the example of a solar eclipse here on earth. when the moon's orbit takes good between us and the sun, it casts a shadow here on ours. when it covers the sun completely, if it goes dark here, when a distant planet crosses between us and it starts the light from, it also appears to us to dim just a little in a telescope. the star flicker is very slight, like the transit method can even be used to determine whether distant planets have that the spears an x. so planet can also be detected via the movement of the star and orbit. as the planet moves around the star, it's gravity causes the much larger body to wobble, a little. that changes its light spectrum. and we can see that if the planet is
2:55 am
moving towards us, the light from it start shift towards the blue part of the spectrum. if it's moving away from us, the stars light grows more reddish of the 1st effect. so planetary system discovered has at least 6 planets a planted circle, our own sun for rocky worlds close in and for gas giants on more distant orbits. another planetary system identical to ours as yet to be discovered. the one around 2500 light years away looks at least somewhat similar. kepler 90 also has a planets with rocky worlds on the inside trucks and gas giants farther out. however, all of them poor bit closer to their star than the yours is to the sun. so that's where the similarities and the
