Moses video and audio production by d w. I hope video with unit being a climate journalist is level all of this. Okay, lets do it. Im do this for you. I think that to be on the next level, i want to show you how to eat entire neighborhoods with water as cold as this is like a thousands of negroes in my legs. The answer with a heat pump, a very big one. But even the small ones are indispensable when it comes to the cabin. Isaac housing. These gadgets can convert seemingly infinite amounts of energy from the environment to warm our homes even in winter. But how is that done and why on the every way it nothing required small Energy Worldwide and keeping houses warm and providing to industry. Teaching accounts for half of the Global Energy consumption and 72 percent. While heating comes from burning fossil fuels long story short to limit Global Warming, we need to bring heating, emissions down. But before we get to that, we need some cold facts. I mean, really cold. Okay, im not ready at all. Oh god its mine is one degrees celsius outside and the water is only like the warmer. Thank you planted a why am i doing this . Again . Its unbelievable. But in the city of month time in south west germany, this ice cold water is used to heat thousands of homes. Were going to find out how this is possible. My name is the mid sized city of about 300000. 00 inhabitants. Its 6 directly on germanys biggest river. Right. And you guys, right. The river plays the key role in this story. The magic is happening in the local Energy Providers producing headed mt thing really makes a fossil fuels and cold water. Until today, the region relied heavily on the most climate timing source for heating cooling. This is felix ok. Hes energy manage it. Energy company, mtv. The magic machine were about to show you is his baby. This single thought plant is responsible for about 6800000. 00 tons of c o 2 every year. Its almost one percent of germanys annual emissions, but this is changing for the better. Right now. The other thing that i am referencing in your own, this of us on this is of the total of the them and then you may have thought of them with the finish up on home and the 5th outside. Ok. And then, but one of them got in the succeeding subset of nashik trips in college in november to them. Its amazing for them on diets under the doorsteps, the name, but that doesnt look like last. So this deafening done is in fact the heat pump for river by pushing through 800 meters over the wall. Type a 2nd. It can provide heat for 3500. 00 households audio rooms. Okay, wait a 2nd. Lets take a separate. This is what happens in all those pipes, the what that seems co to us, but its easily warm enough to turn a liquid refrigerant into guess as this kind of upward. Extremely low, temperature is the gas expense. And electric pump then compresses its gas. This generates heat, its a bit like with a bicycle pump below that your pump, so the higher the pressure, the whole tide gets, try it out. The heat is gas is used to warm up water or f, for example. The refrigerant gives up its heat and becomes liquids again and the process can we saw this mechanism is so efficient. You can generate 3 times as much heat with the same energy as with a gas for that. It doesnt just work with river water. You get the same effect with heat from and the ground. Ideally, the electricity for the pump comes from renewable entities. But even if it comes from fossil fuels, its still more sustainable. The principle of a heat pump isnt new at all. Its based on a concept which has existed for a very long time and on the technology, which most of us have at home a refrigerator. Back in the 19th century, the demand for cooling was much higher than for heat. Ice was carried from far away. If there was no possibility to keep things cool. In 1859, the frenchman fed, you know, kind of a design, the 1st commercially successful ammonia up stokes and cooling system. It works the same way as a heat pump. But the other way around carrying heat from inside to outside from the another familiar machine evolved. The air conditioning invented to salt and submitted to problems in the Printing Industry only day to the heat pump. And its big moments, the pride and joy of the man of the house is the weather control center, a center that puts you in charge of the electric heating and air conditioning. And the electronic air sales are range of the entire house. With western economies booming after world war 2, bringing widespread next weeks vacation and new life style expectations, heat pumps fitted right in. But as most people were happy to buy and cheap or the gas for decades, it didnt really catch on until now. So now were going to see the huge storage from where the distributed over the entire you know this, this is how most tenants the got the inputs of policy and cubic meter bustle. And so its a 1000000 in this of the safety is often available on the services at the moment by phone. The launch is proportional. This is still heated with cool. Only 3 percent of the heat comes from the river, but that was soon changed as the coal fired a station will probably be shut down by 2033. And theyre one of the largest source of your wine and us forensic tullison policy size. A mid to them also suffer them from for us, are fed and others, you know, my, you know, seeing in the next me and as soon as Energy Efficient and sustainable really, the heat pump is taking each from the river means that the warranty is being discharged. 3 degrees quarter after the process with potentially negative impacts on a larger scale. Luckily at the moment, most of which is obviously he did you to climate change, change this beneficial to a point and put you on that you will have need be um, an access ecological effect that you might want to avoid. This is probably an odd scientist at germanys on or a i. E. G, an expert for large scale heat pumps. However, due to the small quantities of water being discharged, the temperature in the river only changes by less than 110000th of a degree according to mtv. But now i mentioned one of them there with ryan, with a major city, so theyre wanting to cover that tie he to month, including industrial tons such as the b s f. So could extra funds along the river line. It will useful to mid that might use water for, for heat pumps, for the processes, and suddenly you get, uh, you get an issue with another issue. All the refrigerants that can be terrible greenhouse gases, which all video and f gas is. If you want to know more, there are alternatives on the market which have less Global Warming potential. But some of the other issues, such as being easy to ignite and manufacturers tend to produce business as usual. Or in my name, the generated heat is distributed by district heating over and across in germany, around 15 percent of all buildings. And now he does in this way. And most of it could be meant by large heat pumps, cutting out cold and gas. They asked of a nice but installation, so start to to pick up a role model is the sweetest capital style calling where about 90000 apartments, a heated from wastewater and the norwegian city of drummond provides most of the heat for its 65000 residents with hes permits quotes, the water and communities dont even need this strategic heat pumps can be directly attached to a building or industrial side where temperatures up to 200 degrees celsius needed. The phones can extract energy from almost any see a way for to see people from the grounds. Is it only to be shoes because its pretty small to be used in almost any residential building like this one a by 20. So the heat pump this could save as many emissions as all the costs, and you have produced a year with smaller units taking a central stage, especially as heat pumps can also turn from heating into cooling mode at a more Energy Efficient than classic air conditioners. But there is a catch, of course, its the money, particularly installing a 1st heat pump, switching from a different hitting system is always going to be more expensive as we all right. Now, this is really something that shes a policy expert at non profit regulatory assistant project. She has a heat pump itself and loves it right now in 2024. Heat pumps can cause 2. 00 to 4. 00 times small the natural gas for this. Its a big outlay, especially for low income families. On the other hand, long term they could save you money as heat pumps need less energy. In europe, households currently save on average 900. 00 per year, and in the us 300. 00. But the advantage of fossil fuel heating depends highly on. Yep. Energy prices is full. The recent energy price causes when prices became unpredictable. And for the tile, on average, of course, your electricity was around 33. 00 times more expensive in gas. So you can see if you having an official heat pump getting a 300 percent full 100 percent efficiency, you might be saving some money back in the u. K, where ours is before the press cost is electricity was 5 times more expensive and gas. So you can see that, that you would really struggle to be saving some money. So if heat pumps almost sustainable and becoming kelly viable, depends highly on your governments energy policies, whether theyve favor cheap, Green Electricity over fossil fuels. In man, im the prospect of high to texas local excitement targets and states subsidies for the construction of the problem with the size. If in the switch to rip a heating that target is to provide almost 100 percent clean heat by 2030 funds will cover all of that. But will be one important component to eventually shut down the dirty coal power plant behind me in the near future. No matter of smaller scale, deep problems, almost sustainable, and can make regions more independent from fossil fuels. And they dont work in winter. I hope you appreciate the effort i flip into showing that.
