Very interesting. You said Denmark has many of these systems for heating water - where is that water stored? They dig large holes for the water? Or in above ground? Im thinking of Ireland here and if something like this was proposed, the first problem would be where and how the holes are created - and associated cost

Hi! They have built under ground water pits, pretty easy construction, not conctrete see my recent clip from this conversation with picture from two of these projects: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-rRq96qcy7EQ.html An evaluation of Dronninglund solar heat and storage system can be read here: www.solar-district-heating.eu/wp-content/uploads/2019/10/Dronninglund-evaluation-report-2015-2017_20190531.pdf Hope it helps but I do think it should work very well in Ireland!

What about the cost though? With solar PV prices way down over the last 15 years, are these competitive. I understand that niche cases where space is limited will favour these, but if space isn't the issue then what?

@EvolutionShowNr1 2 месяца назад

Hi! Cost for PV:s are indeed very low especially compared to solar thermal for household use and the PVs have the advantage of generating power that can be used directly to power appliances or even turn water into heat. The solar heat applications we are talking about is for commercial use, say 10 households or more with district heating and industrial heat processes. But feel free to check out my previous episode with a Swedish inventor that has built a 500m2 off grid house conbining solar PVs, solar thermal and hydrogen he makes from solar power combined with batteries and water heat storage (complicated and expensive yes but very interesting!!).

Has this technology been evaluated in combination with the storage technology of Polar Night Energy? Would they be a good fit?

@EvolutionShowNr1 2 месяца назад

Hi! Polar Night Energy´s sand battery converts electricity into heat in sand as I understand it. Absolicon´s solar thermal heaters is made to be stored in water pits underground for seasonal storage or without seasonal storage to generate heat and steam. Absolicon´s solar thermal technology has been developed over 20 years and it has been proven to work in a number of industrial applications including for industrial heating for companies such as Carlsberg and Colgate-Palmolive. The fact that one Sweden´s biggest and one of the worlds biggest food packaging companies, Tetra Pak earlier this year initiated a collaboration is an incredible recognition for quality.

Joakim was surprisingly realistic, and "balanced" for someone who has been running such a company for over two decades. I think it is important to understand that solar thermal is best suited as a part of the solution, reducing the need for energy from other sources, as output from solar heat collectors is much more dependent on direct sunlight than solar PV, and distributing any temporary excess is really difficult, and storing heat in order to supply all or most of the energy required requires gigantic storage systems to be meaningful. About solar heating with seasonal storage, even to me who isn't a huge fan, the actual cost per amount of energy out from storage from the "large-ish" systems that has been tried that I looked into have been surprisingly high. But, back to solar heat in general, it is also important to understand that multiple factors make bigger systems more advantageous, or, the smaller the system is, the worse it gets. A common household needs most heat in the winter, and that's when you get the least amount of heat. With solar PV you still have use for power when your hot water tank is at maximum temperature, and if you're connected to the grid you can sell excess. Also for the temperatures typically required in domestic situations, solar PV and a heat pump can be more efficient. I also agree that portraying "waste" as a potential replacement for a significant part of fossil fuels is deceptive. We started started to use fossil fuels in large part because we ran out of bio fuels within reasonable distance, in some places thousands of years ago. In no way is it realistic to replace a significant part of current fossil fuel use by change how we use this so called "waste". If we can power our society (in large part) by burning waste, we're producing way to much waste. I think it will continue to become more and more challenging to make solar heat competitive with solar PV, especially for low grade heat. Solar PV technology improves, as does heat pumps, batteries, and essentially everything related to that. And, emissions from manufacturing will decrease, in part because the energy required decreases, and in part because we're replacing fossil fuels in power generation. I don't know if 40 grams/kWh still is about average, I think that's a pretty old number, based on energy generation mostly by burning fossil fuels. Regardless, the actual number is not a constant, it's declining, and will continue to do so.

@EvolutionShowNr1 2 месяца назад

Thank you Erik for very a thorough comment! :) And I totally agree that solar PV for many applications, especially small and medium scale have a lot of benifts in terms broader use and indeed lower costs, no doubt about it. Where the threshold is to make solar thermal installations economically beneficial and in terms of energy savings I don´t know exactly since I don´t have the data but I do see a major benefit we did not cover in our conversation and that is energy security. If we are to prepare our socitety for different types of crisis storing heat to be able to use it on demand 24/7365 especially in the winter time, has alot of advantages. We need heat and access to heat sources in areas where there is district heating and if you already have it stored you don´t rely on on demand deliveries of fuel including wood related fuel. But when it comes to small houses in the country side and old buildings, wood will be gold in times of crises to make sure buildings are heated and for cooking when you have a wood stove! And on waste burning wood products or waste from products we already have extracted: Yes it is already a by-product from extraction/overconsumption of other mostly finite resources and not a solution to the problem. Even a completely circular economy where everything is reused the SIZE of the overall economy is fundamental to make it in sync with Nature/planetary limits. Cheers, Johan

@fishyerik 2 месяца назад

@@EvolutionShowNr1 There are multiple factors that influence whether solar thermal can be better than solar PV, having good use for a lot low grade heat is just one requirement solar thermal needs to be relevant, and the temperature required should be too high for currently available heat pumps to be practical is another. Although possible efficiency, or COP, of heat pumps decrease with increased temperature difference, I suspect heat pumps will continue to become better, I think there's even much more interesting potential there than in solar heat. The thing with truly seasonal storage, as in only "charged" in the summer, and "discharged" in the winter, is the fact that the value of an energy storage system is the the value of the energy you get out of it, and if it's cycled just once a year, that's the entire system capacity times the number of years you calculate the economical life time, which means it has to be extremely cheap to make and run, per unit of capacity. A system that can be partly cycled many times a year when charging it is the best use of energy, and using energy from it is the best source of energy makes more sense, even if the "general" amount of stored energy is reduced during the winter, and increased during summers, and I hope that's what they're doing. Storing heat from power can be extremely beneficial as long as price of power varies between negative and astronomic, which it currently does, year round, even if either extreme is much more common in different parts of the year.

Great if you have clear skies but full cloud??

@EvolutionShowNr1 2 месяца назад

If you have cloudy days all year/most of the time solar heaters are obviously not the way to go.But if you have cloudy days periodically or like in Sweden during winter time with very few hours of sun per day, particularly dec-end of feb, this can be compensated for by storing solar heat from the summer in under ground waterpits to used on demand during winter/cloudy days etc. This is a solution for district heating or approx +10 households sharing the same system and industrial heating or even for a whole city like Helsinki is working on (solar thermal+large underground waterpits for seasonal storage). There are rarely one fits all energy solutions. Combinations are often the best way to go for redundancy and for the freedom to not completely rely on the grid. Cheers, Johan

Why not use solar PV (20%) and a heat pump (350%) to give a comparable efficiency?

@altosack 2 месяца назад

I’m interested in putting a greenhouse on the south side of my house, and running an air-source heat pump in there when there is excess solar electricity, which coincides with warm temperatures in the greenhouse. The COP should be even higher than what you mention; the limitation is storing the heat in what will already be fairly hot water.

@michaeldepodesta001 2 месяца назад

@@altosack Good Evening. I'm afraid a greenhouse is unlikely to improve matters. Why? Well the heat pump extracts heat from the air by cooling through around 3 °C. If I remember correctly, heat needs to be extracted from roughly 1 cubic metre per second to extract heat at a rate of 3 kW. So a greenhouse might have a volume of say - at most - 100 cubic metres. This would only provide heat to run the heat pump for a few minutes. In fact the main requirement is to have access to lots of air. If you have *lots* of warm air then great - but heat pumps will work with air well below 0 °C. Does that make sense? Best wishes Michael

@altosack 2 месяца назад

@@michaeldepodesta001 - The air differential temperature will be higher than 3 C at the elevated greenhouse temperature, but that is irrelevant. A 3-ton heat pump is transferring about 10 kW, or about 6 MJ for a 10-minute cycle. If we ignore heat replenishment by the sun, that would reduce the temperature of 600 m3 of dry air by about 7 C, which would be acceptable. Well, the air will _not_ be dry, and the temperature will be continuously replenished by the sun, so I think I will be OK.

@EvolutionShowNr1 2 месяца назад

Just by installing a Green house directly against a wall of the house will save you alot of energy, I will do the same for the energy house I have designed (check my comment above for more details). It creates a barrier against the wind/cold and heat the air protecting the outer wall from the coldest air trying to get in. I have considered circulating warm air from the green house into the ventilation system and make use of the heat their but in can become complicated/tricky so I think I will stick with just controlling the climate in the Green house manually opening windows and doors or automatically with the roof top windows opening when it gets too hot during summer. Cheers, Johan

@michaeldepodesta001 2 месяца назад

@@altosack Mmmm. If you are removing several kW of heat from the greenhouse then it will cool unless the solar flux matches this. But if you have a high solar flux may be you don't need a heat pump, just paint your walls black or install windows. In any case: good luck with your experiments. M

@D7nam1k 2 месяца назад

PV + heat pump with SCOP of 3.5 is as efficient plus you can store it and export it for money. Heat is useless once you have enough. Also electricity is a higher quality of energy. Converting it back to heat is easy, not the other way around. My bet is on PV all the way except some very niche situations. Unless someone can prove me wrong on the PV + heat pump comparison

@EvolutionShowNr1 2 месяца назад

Hi! I will install a heat to water heat pump for the energy house I have designed with my father together with water ciculating floor heating, SCOP is estimated to be above 4 on an annual basis. This will be combined with Masonry oven that has an efficiency of about 80% that will be used in the winter time to heat water in a tank circulating under the floors and heat shower/water for washing. A 17.5 kW solar system will generate power for the house mounted on a South facing roof of which 4 kW will installed on South facing and East facing walls for the fall/winter sun and generate some power even during winter time when roof often is covered in snow. Surplus power will be stored in batteries and water tanks. Ok, you say heat is useless once you have enough. Well in Denmark over 120 communities now heat their villages by storing surplus solar heat during sunny summer days/daytime in underground waterpits where heat losses are extremely low and can be used 24/7 all year/as seasonal storage in underground waterpits. The heat is spread using district heating. Wherevever you use distict heating like in the Nordic countries in many parts of Europe like in Germany you can replace burning biomass or Natural gas with solar thermal heat either only during summer without heat storage or all year with waterpits. They use solar thermal fields to heat the water/store it. This technolgy/combo is spreading and will be used in Helsinki to replace heating from coal for a million people by 2030 starting construction this year. We are of course talking about commercial applications here not for single use households but even for ex just 10 households using a shared heating system could combine solar thermal and waterpits or just use solar thermal. Solar PV are great but why not combine it with solar thermal where applicable? After all, storing solar heat directly is much more efficient in water as a large battery instead of generating solar power and store it in batteries. Cheers, Johan

@D7nam1k 2 месяца назад

@@EvolutionShowNr1 If you have a large low heat loss storage solution that changes the matter yes. But in general I feel most people are too hooked up on 'efficiency' and not 'usefulness'. For most people with no large storage oppurtunities and limited roof space PV is simply a better option I feel. But very cool that in some places they can run off summer heat!

@@D7nam1k Totally agree that with limited space for small applications and with costs considered PV is a great choice but for many industrial applications and where district heating is already in place solar heat solutions like Absolicon´s solar thermal system is a very good compliment! :) The problem is that very few cities and companies still know that this technology even exists and is very useful to save heating costs and make use of industrial process that require and waste alot of heat. Carlsberg and other breweries as well as Colgate-Palmolive have realized this and installed large solar thermal systems at one of each companie´s factories.

@energyideas 2 месяца назад

wrong, if just making heat, non-glazed collectors, like pool heaters, are more efficient. Heat isn't as valuable as electricity. The collector shown is a concentrating collector, meaning it can only use beam solar component of the sunlight. Sunlight is primarily ~80% beam, and ~20% diffuse. These collectors do not concentrate diffuse, so right off the bat 20% of the solar radiation is not used. Using the mirror to concentrate looses 10% of the solar radiation. This video is misleading.

@EvolutionShowNr1 2 месяца назад

Hi! You absolutely right that concentrated solar collectors are not suitable everywhere where other alternatives are more suitable including PVs. If we talk sustainable heat sources it could be geothermal, heat to air pumps, heat to air water pumps or good old masonry heaters that are super efficient with almost no pollution at all. But I do think Absolicons CEO Joakim Byström is quite clear though that we need to combine different energy sources and technologies depending on local conditions such as climate/cloudyness, energy demand etc. I also think solar collectors can be very useful when you have district heating already in place llike in many cities/communities in the Nordic countries, Germany etc and in energy intensive industries like breweries and for making clothes and the chemical industry and indeed packaging industry where heat and steam is used alot. Hope you like part 2 better! Cheers, Johan
