the food is not wow, i'm flipped up, but also when it comes to sustain dependency information and trend executive on d. w, travel, you can have it, whatever. did you what your opinion feel free to write your thoughts and the comment? the what would life 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 a most sustainable so that's that's a move from the welding for such on dw sign shift. welcome to tomorrow. today the producing steel requires temperatures of over $1500.00 degrees celsius,

burning oil and gas. as 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 and the future. cheese designed parabolic reflect there for capturing and concentrating sunlight to do so 9. 0, i don't know if it's this. i'd say the potential is huge because there are not many alternatives for producing high temperature heat from renewable sources. a 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, good tons at 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 light is collected by

a parabolic reflector and the sun's rays are concentrated 1000 fold to produce steel. thousands of mirrors would 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 necessary to power a small steel works. 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 centimeters of, of solid parts. concentrated sunlight gear,

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 sheet 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 the thermal energy equal you deliver is just the mother of k. so you can do these 1000 times larger than you . we've got 1005 is more that will 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 really ships tensile are and 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 to any alterations. would some places be more suitable for solar powered blast furnaces than others? some morning did 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 a lot of solar energy on this. and even if the sun does shine less in europe than

in arizona, so more heat could one day help make c o 2 free steel production or reality there as well. the only way that's not everything that's possible in scientific times can be implemented successfully and sustain for example, capturing the greenhouse gas c o 2 for storage. so when on the 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 2 thousands pants that low phones were brakes and green day was having a moment. but if you're a climate scientists, you are probably focused on a different hop topic, carbon capture and storage. so basically, capturing fuel to from a plant that burns fossil fuels appearing an underground technology promised to

become key and fight and climate change. the most effective way to help help were to meet it's emission reduction goals. the world has changed a lot in the last 20 years. but it's still not that widespread. they have failed to meet the promise function in terms of the quantity of the quality of what they during cc's or carbon capture and storage sucks up a portion of this youtube released at a fossil fuel plan. then companies can transport that through to l squared to store it away by injecting it into rocks into the c bed or into old oil 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 air capture or deck which in comparison a full baby text here, giant fans sucking air and pass it through the filter or through chemicals to trapped c o 2 particles. these can be collected and stored underground. so basically 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 atmosphere is essential to help us become climate neutral by 2050. but we're a severely lagging behind. these technologies are only capturing 0 point one percent of our global emissions, meaning we're playing a mass of game of catch up in the ninety's and securely in the of the 2 exams. and so that was an awful lot of promising a fact cause and capture and storage that was in price price also fuel jump then use that was seen as is the way to, to square our emissions targets and, but to go on offer anything. and the international energy agencies roadmap 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 while some of these projects are called it a successes,

the list of failures as much longer to been as 10 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

the source of emission says. but it's about 15 to a $120.00 per metric. com that is captured just for reference a ton of c o 2 is what? 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 with cps 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's the su to 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 and e s big oil has actually been to think away from investing into

renewables. 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 60 as plants pump, the su to, they trapped them to aging fuel 6 tract leftovers because oil is really stuck in sick. 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 flip the field with c o 2, which works kind of like a lubricant. it makes the own more liquid and increases the pressure to get the crude out of the rock. this procedure is called enhanced recovery and 70 percent of the easiest plan to use it. the positivist it can be a carbon capture more profitable, but it also means more oil. the newer oil is either used as a feed stock in 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 is. climb works, ma'am. of plant has the capacity to suck up to $36000.00 tons of c o. 2 of the apples here over here in the grand scheme of things that's a miniscule 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 of the prophecies that the direct tech capture. if we're able to expand direct 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,

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 in 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 is different and becomes more urgent, right? how do we measure the important stuff? what's 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 baffled trucks or volcanic rocks and the company says it will not engage 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 6, yes, 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 lodge on to direct air capture, but this cannot become another wave of inflated goal. so keep business running as usual. it's simply cheaper to avoid a ton of future today than to take it out of the atmosphere. otherwise 20 years from now, we'll look back to today and realize we over promised once again. hurricane heat waves must've rain, full human induced climate change, his excessive aid to the extreme weather events in recent years. at the end of october 2024, over 200 people died following stats in spain. while in germany, walsh is 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 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

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 bio diversity the the next now so immediately after the flood, had collapsed completely. many species disappeared and biodiversity hasn't bounced back fully. 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 team take samples and a number of points in the river. or they also monitor water quality, which is closely linked to the wellbeing of the rivers. fiona nutrients that

promote the growth of algae or one parameter they leaked from waste water systems heavily damaged by the flooding that are treated waste water was discharged into the river and that waste water contained a lot of nutrients. we now want to investigate in more detail how things will develop over the next few years. those investigations are carried out and allowed at the university of co plans. 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.

any changes are desperate, just start quickly to buys even. for example, when ours works are dug out to build a new bridge. it can quickly cloud the water or set free nutrients or pollutants that may have accumulated there during the flood and allow tom and then the work release is and mobilizes them again at 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. and elaborate that clear university of applied sciences. the young researchers therefore, also analyze how many invertebrate micro organize sums are found in the samples. under the microscope, the team sorts the animals into different groups and determine species like this

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 rich water. that's what i should call the initial results show that some species are already re populating d r 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 the 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, plans should incorporate a residual channel where water always flows where species that depend on water could survive. so i'm going to use and believe and conservation plans for other

rivers will also benefit from the findings on the are the to figure out how well the works exactly, and full cost it accurately, we rely on satellites. what influence, for instance, do clouds have on cooling or woman processes in the atmosphere? in june 2020 for a new e. so set tonight 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 darmstadt, the tension rises. it looks like we have a signal that sign into a service stablished contact with their satellite success, fully mastering another critical phase of today's launch. firstcare thing is up and rolling the data and so forth. thank goodness we're really relieved because it

doesn't always happen at 1st contact. in fact, it can take several lower bits. so it was perfect. perfect. the 1st critical moment had come and gone just under an hour earlier when the space ex falcon 9 rocket carrying the earth observation, satellite launched in vandenberg, california. everyone involved was holding their breath on take off the 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 an atmospheric interactions. climate and weather 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. something that we watch unprecedented as the combination of 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 dismissal times over the next few years or as care will observe our planet from an altitude of 393 kilometers it's instruments will send out light pulses and analyze the reflected signals. among other things, the researchers want to use the acquired 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 meeting is using existing techniques. for example, with optical sensor, as you observe the 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 movement. 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 uses. director general says the cooperation sends an important signal about remaining competitive in space that went 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 countries. i guess i'd be doing. so the big defend the difficulty at $300.00. it's still 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,

largest and most complex 1st observation mission today, designed to help us better understand how our world works. because what is read? why do you have a question? trust 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. within 4000 planetary systems have already been discovered in our galaxy alone, most or so far away, the telescopes can see the stars directly,

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 get between us and the sun, it casts a shadow here on ours. when it covers the sun completely, that goes dark here. when a distant planet crosses between us and its star, the light from it also appears to us to dim just a little in a telescope to star flicker is very slight, like the transit method can even be used to determine whether distant planets have at the spheres 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

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. the 1st effect, so planetary system discovered has at least 6 plan of 8 planted circle. our own sun for rocky worlds close in and for gas giants on more distant orbits. another planetary system identical to ours has yet to be discovered . but 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 for bit closer to the or star than yours is to the sun. so that's where the similarities and the

not safe for now. but we look forward to seeing you again next time on tomorrow today. by the, [000:00:00;00]
