      Where does the heat for your system come from?
      Also would it make sense to have a central heat storage system but each building with its own heat pump system to extract heat from that storage system? Iam think that would make it easier to regulate the heat in a building.

Now my knowledge on the subject is fairly old, but from what I remember, the heat extraction takes the place of the lowest pressure turbine, and is therefore able to extract much more energy out of the steam compared to if it was used strictly for power generation.

    Nice job. I'm one of the the large group in Sweden that has heating via district heating. I previously had natural gas and then moved to my own house with district heating. I can testify how convenient the energy source is and how well it works despite long periods of cold. Yes, it takes time to build infrastructure with heating pipelines in the streets. When the job is done, it only has profits.

    This sort of system is also great for rural areas but with individual units per house. By taking the warm grey water from showers, clothes washing and dishwashing and storing it in an insulated tank underground a homeowner can extract the heat from that grey water and send it back into the house for space heating, heating water and clothes drying. The same tank can also be used to store waste heat harvested from PV Panels until needed and the heat pump can be a dual system extracting heat from both the ambient air or the tank. Grey water from the tank can also be recycled and used for flushing toilets reducing the intake from wells and the output to the septic tanks thus reducing overflow which is another common problem with septic tank systems. The grey water can also be used for lawn and garden watering during times of drought or low well water The insulated tank would need an overflow into the septic system when needed.

    Here where I live in Mount Pearl NL , Canada we have a much smaller and different system but with the same results. Waste heat from two twin hockey stadiums is used to heat the water in a swimming pool as well as the water for showers and it also heats the space inside a gymnasium and other buildings nearby. A small Ground to Water system provides back up when insufficient heat is available from the stadiums and rain water from the roofs and from the showers is stored and used to flush toilets. The system was expensive to install but paid back quickly over several winters.

    Still not convinced of the benefit of heat pumps or heat networks. There's no economy of scale. Drilling costs are the same whether for single home or municipal, apart from lower mobilization costs, but those are offset by havong to build a piping network between homes. Overall it may be competitive pricewise with electricity costs at this time, but that's mainly because electricity costs are high in the uk.
    Also the whole direction the eu is going in is wrong. All they are doing is trying to reduce electricity usage. This only stalls energy transition to electric, when instead they should be trying to provide more and cheaper electricity. I think it is very ingrained in eu spirit that global warming means lets save as much electricity as possible (meanwhile ignoring coal and gasoline).
    Let's see if I'm being consistent. On the one hand I think water heat (or cool) storage is a good idea, because it allows bridging times of day with less renewable electricity availability. So this is being used in the gshp here as well, but it actually makes a lot more sense in the electricity intensive (plain heating cooling) framework. I guess what I'm saying is distributed electricity + thermal water storage (no network needed) is more practical, water storage doesn't have to be tied to using gshp and heat networks.
    On the upside, the infrastructure investments for heat networks make more sense in a london or nyc environment where you want to centralize these heat exchangers and boreholes because of space issues and maintenance, and it also means probably better water/sewage infrastructure maintenance which is typically neglected but with the additional workforce in this area you'd see this get more attention probably. And lowering electricity usage in a massive city isn't a bad thing but again I think it sets the incentives wrong. It's not an accident that the eu is the most resistant to retiring fossil fuels.
    Then again all that's needed is political will and in the meantime heat pumps heat networks are as good as building out renewables in terms of co2 impact, with local labor instead of imports from china.

    • @xxwookey
      @xxwookey День тому

      No - drilling costs (per building or kWh) are much lower when done for several homes or a large network like this. A borehole for a single home is expensive. A borehole for 10 homes isn't. We have to ignore coal and gasoline because we have to decarbonise. Thermal storage is cheaper than electrical storage for daily variations, but it's not _that_ much cheaper any more (16 kWh of battery is £1700 and is the same energy as 200l of water (£750 tank) heated from 20 to 90C) and the heat is a lot less flexible than the electricitiy. Heat pumps get you 3 times as much heating (or cooling) as direct electric so why wouldn't you use them? We've all been using them in our fridges for decades - it's not a new technology.
      Also the reason for reducing load by improving buildings or at least using heat pumps is that peak load (in the UK) is winter heating so that's what sets the size of the your generation/supply network. Anything you can do to minimise that peak load reduces the very large capital cost of the low-utilisation kit that supplies the last needed kWh.

      Amortized extra cost for the heat pumps is a wash with less electricity use, but it does reduce winter kw peaks so as I admitted it is competitive with adding new renewables and helps the local economy. Ideally the focus should be on both, especially renewables because at the end of the day the only true win in decarbonization is to replace fossil fuels, not just save electricity

      @@Rene-uz3eb A heat pump costs about 3-4 grand, maybe 8 installed, and if you use UK average of 12,000 kWh, then doing it by heat pump will be only 4000kWh of actual electricity so the cost saving at standard rate is about 2 grand/yr. That means it's paid for itself in 2 years over direct electric. That not 'a wash' - that's a dramatically quick payback. Much less difference between gas and heat pump, but you should still save money whilst decarbonising (unless it's a shonky install).

      Other than electric heating, we have nuclear and burning fossil fuels; both of which produce dangerous byproducts. Can you suggest some other methods that are better than electric?

      They are capturing low-grade waste heat, water is best for that as you're using the storage medium as the heat delivery medium--no conversion losses.

      nuclear is the best, there are quite some that is it's heat for district heating.
      And Poland will do this to.
      And there are going to be nuclear for only heating, a simpler system.

    Great video, with interesting tech.
    Both of the speakers should rethink the use of the word “obviously,” as there is absolutely no need to say it. If something is obvious, you don’t need to point it out, unless you are trying to convey to the audience that YOU know it is obvious. The word is arrogant. Please stop using it as it is completely useless in the sentence.
    Say the sentence again without the word. Has the sentence lost anything? No.
    Think about it.
