Inside the world’s first giant heat pump that heats an entire city with CO2 and sea water
This is the world's first giant heat pump to serve as a central heating system for an entire city with tens of thousands of homes, using CO2, sea water and genius large-scale engineering.
Thanks to this heat pump, the city of Esbjerg in Denmark, will be able to quit burning coal for heating and use only renewable energy in one single move.
How does it work? What's the genius idea and secret components that make this concept viable? And, of course, how efficient can it be in energy consumption? In this video I find the answers from the engineers that created and manage the brilliant system.

I am aboard a battery electric ship operating for 5 years now
zhlédnutí 1,1KPřed 5 měsíci
I am aboard a battery electric ship, operating for 5 years now as a ferry between Helsingor in Denmark and Helsingborg in Sweden. When it was launched in 2018, it was the largest electric ship in the world. After 5 years in operation, it has proved that it can work in real life and recently it has received an update to be able to serve for the next 10 years. I went to Denmark to see it and cros...
The story of the world record Tesla with 1.9 million km and its owner
zhlédnutí 607KPřed 6 měsíci
Hansjörg von Gemmingen-Hornberg owns the Tesla Model S with the highest mileage in the world, as far as any public records show. His car has 1.9 million km / or 1.18 million miles on the odometer at the time of filming and Hansjorg aims for more. There is little precise information about him online, mostly based on some older tweets or on assumptions of how he manages to put so many miles on hi...
1.2 million km battery life in a Mercedes electric long-distance truck?
zhlédnutí 2,2KPřed 9 měsíci
How long should an electric truck last? Mercedes says its new eActros 600, being in its final tests now before launching into production, will last 1.2 million kilometers, or about 750,000 miles! But the main question is: will its battery also last 1.2 million kilometers or it will have to be replaced several times until the truck reaches that mileage? I have contacted Mercedes team, working on...

This is Heart ES-30, the electric plane which is to become the world’s first to fly passengers on a regular route. No other plane has advanced so far in its engineering to be able to operate regular commercial flights, so that intrigued me to find out if its creators have managed to overcome the crucial challenges that have prevented us to see electric planes in operation until now and that sti...

I have bought the heat hump for my own house, making my own, independent decision, so you will hear my genuine experience and technology explanation from the point of someone that has made an investment in this technology and after a complete cold season can share the actual impressio...
What is Watt Energy channel and what do we cover here?
zhlédnutí 868Před rokem
A warm welcome to Watt Energy channel! Get to know here the universe of subjects we are covering on the channel. We explore some technologies that are already here and form the most preeminent trends - heat pumps, electric cars, trucks, planes, ships, synthetic fuel, hydrogen, solar energy, wind energy. But we do also sometimes explore and get to know or remember some solutions that have a long...
(1) In drones, it is common to see take-off and landing using electricity generated by gasoline-powered auxiliary generators. Since this aircraft has 2 APUs, why not use them to generate the extra power demand for takeoff and climb? (2) I believe that the use of batteries is a temporary solution, until the technology of generating electricity through hydrogen cells is more mature.
Sorry but a 737 APU is 90kw each main engine is the equivalent thrust of about 40 MW . A small aircraft would have a much smaller electrical demand so the power output of the APU would be minimal compared to the main engines. Storage of hydrogen in aircraft is tricky involving cryogenic refuelling. NH3 might be a better option as this can be liquified at reasonable pressures and would burn fine in a turbine with modifications to the fuel injection.
I'm wondering can that compressors be driven by natural gas combustion engines instead of electricity?
this video made me consider buying an electric BMW instead of a Tesla... seems like BMW hit the mark with this car
this is the guy who: how far do you drive sir? this guy: yes (ja)
5:33 for 1kWh consumed it generates 4kWh of heat? Isn't that backwards? Sounds like it breaks the second law of thermodynamics a little
Yes, 1 kWh of electricity generates 4 kWh of heat, that is why heat pumps are efficient. The explanation resides in the fact that a large part all of that 1 kWh of electricity is consumed for the mechanical work of the compressor, while the heat is generated by having the gas (refrigerant) compressed, plus the fact that a part of those 4 kWh of energy at the end are gained by capturing heat from the primary medium and absorbing it into the refrigerant.
“Are you a taxi driver?” First thoughts no a rich idiots
The refrigerant is liquid before the expanaion valve not after. If you havd liquid between the expansion valve and compressor youll pump liquid in the compressor which isnt compressible, breaking ghe compressor
Reality: using the gas boiler 99% of the time to cut the cost 😂
Sad guy
czcams.com/video/-bIlAkTDw8Q/video.htmlsi=PGVZcj7uO8hXU4z8&t=1894 Units analysis at 31:34 doesn't add up btw.
WTF is district heating? Is this a word we have in America? Like Washington, DC (district of Colombia)? In America, each house usually has its own HVAC equipment.
Windmills are shit, you need to get nuclear if you want real power.
Or you learn how to get by with less power ...
BTW, I agree we need may small thorium reactors.
I need the oposite, to coold down hardcore
I wonder how possible it would have been to have both a city-wide heating system and citywide cooling system using the same plant for transfer of energy
Air-source heat pumps can use between 545 and 7,500 watts of electricity. Mini-split heat pumps can use between 500 and 1,500 watts per hour, with an average of around 800 watts. The size of the unit is a key factor in determining how much electricity it will use.
Fabulous! If only all areas of the world can work towards this goal, we would really be in better shape for the future, eh? (It is expensive of course, and some areas couldn’t afford it at first, but maybe with time costs would go down, and perhaps too, grants could subsidize some of it too?) Thanks for the great video! 💜
Sir a question In the golf country’s very hot. Is there is somehow can it provide a cool cold ty
Why not use the chilled seawater as a secondary coolant for the vfd cooling water loops ? Perhaps they did this but didn’t discuss it. Excellent video
C02, seawater, oh yeah and a giant pile of burning wood. Don't put that last part in the title. It's not important.
The heat pump has to have alternative sorce of heat like wood chip to get the higer temperature
Amazing!
Then why the long face?
Very interesting video. I would just suggest that a quieter place for most of the interview would have been a good idea. I found it hard to understand what was being said because of the loud background noise (I turned on the closed captions).
fake title... water + co2 don't produce heat!
Can cities or companies use water pumps with large water tanks to create energy batteries?
Germany does it. Pumping water to a higher lake in times of abundant electrical energy.
I hear Deutsch
They have something like this in the new stem building at my college.
I'm starting my second career as a commercial HVAC technician and I'm working on a startup to make indoor gardening facilities more efficient. I was able to easily follow the discussion here and I'm impressed with both the clarity and detail you were able to achieve in this video. Thank you!
Thank you!
Difficult to understand with the background music.
Why not put in the title? 10 replaced engines? And 3 batteries...
Nou nee laat maar !
Not a complete heat pump. 19 May 2024.
A really interesting video and topic, this equipment is undoubtedly at the top of development’s of technology AT THIS TIME, use and monitoring will provide all the info needed to see what changes/ additions are useful. This is the correct approach governments L.A. need to adopt and people need to pay for
Heat exchangers

Oh ya CO2 because they didn't want to spend a billion on refrigerant , so they Use Plant food CO2
Here in North Carolina USA we do just about the opposite with heat pumps. Since it is warm most of the year, we use a heat pump to take the heat inside the home and put it into our domestic hot water system in the home. Normally this cost for hot water is the equivalent of about 5 Euros per month ( After the initial cost of about 2000 Euros ) for our hot water not including the free cooling in our home from dumping the heat into the water, then ultimately through the hot water use and into the ground. ( You got to love the magic of engineering )
All im hearing is ... electric heater and wood chip heater .. so no real energy saving. Infact, if you take all the bullshit consumed during construction and political aproval, i think this was a waste of time.
How much watt per hour does the average household compressor require, any info in this video? Couldn't find any
An efficient heat pump, in an insulated 140 m2 house, would consume between 400 and 900 kWh monthly in a winter month, depending on average temperatures. The upper level would be valid in a cold month, with frequent -5 to -10 Celsus at night, or even -15 and lower. The lower consumption would be valid in a warmer month with positive temperatures of about +3, +5 during day and around zero at night. There may be big variations for this number in case of an apartment, and depending on the COP of the selected heat pump and the right installation and the setup of the system. I promised earlier to do a video with the numbers I have obtained on a larger home heat pump system, on a larger area to heat, so will definetely come with that video with all the numbers revealed and commented, from my experience.
In the Netherlands I heat the 140m2 house with 1800 kWh per year. Daikin 5 kW multi split airco system. Most times the Daikin airco uses 600 Watts.
COP of 2 in the middle of winter is disappointing. Add to that the losses during piping then it's not exactly great.
Furthermore, that is when the system is needed the most. Good catch.
I picked up between 2.8 and 4. When did you hear 2?
@@JanKluiver Maybe Jimmy meant 2.8 , but still I find it hard to believe ( I could be wrong ) that any devise can get a COP of above 2 with an inlet water temp of about 1 degree C.
@@JanKluiver You're right, it's 2.8 which is still terrible considering we haven't included transmission losses. I would expect better than 4 during summer on an industrial scale. Off the shelf home units can get 5.
@@JimmyLLL Those transmission losses will be around 20-30%, which are mostly due to the loss in the warmer half of the year (summer), when little heat is needed, while losses remain high. I agree that a COP of 4 in the summer sounds not impressive. The input temperature of the seawater will go up, while the output temperature can be lowered. Nevertheless, I feel confident that they have done the math and that this will be the (near) optimal configuration. Regarding the heat transmission losses. Don't forget that the heat distribution system was already in place. The goal is to replace the existing coal fired heat source. A centralized investment of 1500 euro per household is cheaper than fitting houses with individual heat pumps. And even if individual heat pumps would be cheaper, I wonder if all those houses have space to fit one.
I call bs that the windmills are supplying the electricity maybe a fraction when the wind blows. Now you’re probably burning natural gas to generate electricity meaning you still have a large co2 footprint. Also bet heat coats have skyrocketed
Do you have any knowledge of Denmark, or are your claims rectally sourced?
'refrigerant'

Bless the Danish and their "grid balancing gymnastics" -- but this is the dumbest/stupidest renewable-energy contraption I've ever seen. (Have to feel sorry for the manager how has to describe this contraption.) 1) there is nothing unusual happening with the climate. (Please explain the Little Ice Age and the Medieval Warm Period.) 2) there is nothing wrong with burning fossil fuels. Its problems in high-density areas are trivial to fix and already have been fixed. CO2 is not a pollutant. 3) Climate alarmism is a big-lie superstition supported by tax-bribed liars. (See Climate Discussion Nexus for 100s of videos on climate quackery, deception, and realism.) 4) decarbonization is 21st century pyramid building and human sacrifice. 5) there is NO excuse for expensive electricity. Electricity generation is boring. Just burn coal and scrub the smoke in densely populated areas. 6) the only challenge is manufacturing market quantities of cheap gasoline. South Africa has already done this for decades (Sasol), using coal. 7) Elon Musk: the Laptop Class is in La-La Land.
Alo domnii politicieni luati lectii !
The dumbest "renewable energy" contraption I've ever seen.
The U.S. Congress would not be able to understand how this works. Most of them have not seen a classroom in 50 years. Plus I think they enjoy stealing oil from other countries.
I'd accept a slightly higher energy use per home when i also don't have to worry about my personal heat pump failing, causing me to lose ALL heat. While this is not remotely feasible where i live in the USA, i'm jealous of this awesome system!
This is not first. In Helsinki has too heat pump in district heating.
Yes, there are more examples of heat pumps for district heating, the world first part here is having a heat pump of this scale using sea water as heat source and CO2 in its circuit, while also being capable to ensure such high temperatures on exit that it can operate with an old city piping system.
200km? I will use car instead.
If they have considered R1234 and ammonia, why have they not considered propane?
