Immaculate installation and really environmentally friendly! Greetings from Spain.
Great film and idea to make it by David. Greetings from Chalmers and Sweden. Valery
Gohenburg rocks!
Thank you for effort 💖
Absolutely fantastic. This brings together what are now maturing technologies in a way that almost creates real energy security from off the shelf components. That is an achievement which would have been un-realistic 25 years ago. Truly off grid. This has such potential to be something communities can be built around. I would love to be part of what you are doing.
excellent, Many thanks for sharing some inspiration for Southern Africa
Hydrogen House Project is already using a combined system of Hydrogen and Solar Electrolysis, for 16 years now :)
3 Months generation via solar powers the house for the whole year via hydrogen, with solar supplementation as needed or available.
I love the attention to detail to find every spec of efficiency. However, the PLCs themselves are going to be well over £5000
PLC what is that? I know that those sunny islands are quite prohibitive in cost vs normal inverters or similar hardware..
Mike strizki hydrogen house usa. Wonderful workmanship
As a first step, this is a wonderful example of entrepreneurship at its best, along with exquisite Scandinavian design to solve the home energy problem for a colder climate in a "green" sustainable manner. As such, I'm not too concerned about the current cost. The fact that all the systems work together to produce a self-sufficient home energy solution is what is important. Costs will inevitably come down as the various parts become more efficient and mass production increases. I was also impressed that technical information for each of the sub-parts was provided. Would love to get more involved in this "green" hydrogen revolution.
Thanks
Good show, few things are extra, would be interested to discuss implementation in a tropical country using solar, wind and Hydrogen only.
Hydrogen House process must in use in european country suffering in LNG cris,until there is no final plan natural gas supply. these hydrogen process will use in many generation,,believe it or not,,this process will use FOREVER🤚
Feeling like ordering one for all homes, have you had a chance to update an inventory of possible replacements as to save mostly space?
They seem to have missed a trick here. Solar panels are 20% efficient, electrolyzers are 70% efficient and fuel cells are 60% efficient you are having to throw a lot of solar panels at this to compensate for all the losses in the system. It might be easier just to use solar hot water and store the heat directly in a heat battery. The vast amount of energy in the house is just energy for heating.
The issues with batteries and solar heating are that they just don't hold what energy was put into them for use later and extremely low specific energy.
You forgot one point, he is using the heat losses from both electrolyser and fuel cell. This way he has a way higher overall efficiency.
This system runs for several years now and it is working. But he does use alot of energy for de-icing and melting snow an his driveway in the winter etc.
They also made a 2.0 and up to this year probably a 3.0 version of the same basic system but striped down to what you need for a simpler house around 150m² living space. And the efficiencies of all parts are getting better every year.
75% for electrolysers has become industrie standard (SOTA ones even reach 83%) and several companys working on way more efficient versions.
Hysata for example has proven that they have a slightly different way which in the end can reach up to 95% efficiency. They plan to scale into the GW range by 2025. A nice video about this can be found here: ua-cam.com/video/m0d6iljzzEI/v-deo.html
Good example of the past. However advancement in technology today may make this house use less separate features and more affordable.
Excellent helpful discussions.
HYSR SunHydrogen scientists in multiple USA universities have been working on green hydrogen for years and years. They have businesses relationships with multiple international companies to bring their products to the commercial market.
We're better off making green gas by adding an element of carbon to create Methane, that way it's far safer, denser, and can be utilised with existing gas infrastructure. Simply get charcoal from wood and you're pulling the carbon out of the air to make new hydrocarbons with electrolysed Hydrogen.
Great video spoilt by the excessively loud pornography music.
He saved like 500 usd by month, This could cost 100000 usd, this mean that in 200 years he will be living for free.
Ah no.. I forgot the lifespan of the hardware..
No.. seriously.. most of the hardware he has, is ultra high quality, like those sunny island.. a ton of hardware to regulate every single aspect of the system that increase the cost over the clouds.
But it will be nice if someone develop and mass produce an all-in-one reversible fuel cell, with only 2 hour of battery storage and 200 liters stratified water tank and modular extra hydrogen capacity.
Why not use a magnesium hydride or newer solid state hydrogen? It wouldn’t be off grid but would eliminate the need for 50% of this system. This system is so massive that most homes especially the smaller homes in Europe and Asia will not have the available space. Fascinating concept but i fear might be impractical for page scale use hurting profitability to implement.
could you tell me where is that hyrogen house address ，
There are not enough raw materials to apply this everywhere
LA CE PREȚ AR AJUNGE CU TOTUL ?
Very interesting, but a cost/ benefit analysis is essential to determine the viability of the system. I know it is a prototype for research, but it is hard to imagine a cost effective version for the average home. Hopefully, hydrogen can be made to work for the average household.
what will cost the most are your solar panels and tanks, but after these expenses they essentially make what is produced completely free, can you imagine converting your house with one large expense and not having to pay for your electricity for the rest of your life after that?
the savings for your future are unparalleled especially since the rise of electricity will go up with inflation and the cost of everyone moving to electric cars which also means the supply needs to meet the demand, but if you have something that is supplying everything for you without needing grid energy, you are living Scott free in comparison to any other person around you who is still paying for their power source.
can you imagine never needing to pay your power bills for the rest of your life?
This "sweet old man" in the video is an ignoramus and a liar. Why the harsh words? Let me explain. "a cost/ benefit analysis is essential to determine the viability of the system." LOL. It's obviously not viable; otherwise this guy in the video wouldn't have prattled on endlessly about the supposed benefits without implicitly ignoring the elephant in the room: the cost/ benefit analysis.
It's no secret that vast sums of money are being poured into R&D these days for photovoltaics (PV) and batteries. Hydrogen fuel cells, used in the manner he described, might be viable one day, but they almost certainly aren't now. Engineers like this guy are prone to tinkering for their own fun and pleasure; yet frequently like to claim they are trying to do something grand such as, "sAvInG tHe WoRlD."
This is much like a musician who practices his beloved instrument endlessly, claiming that he wants to "share my music with the world", when in fact, primarily he likes to play his beloved instrument.
Evil rarely announces, "Hello there. I am evil!" Normally it uses nefarious methods. This "pleasant old man" has deluded himself into thinking he has found "The Right Way." Sure. Maybe one day his method will be right; but today it is wrong because it's much, much too expensive and inconvenient.
I wonder how much this system costs? If its anything above 50k euros its just not worth it if you use anything less than 1000kwh per month @ 0.21 Euro - thats "free" electricity for 15 years from the grid even if prices rise. Not to mention you can buy remote solar park (roughly 10k euros for 10kw plant) and just pay transportation fee (0.05 Euro/kwh) and yearly care cost (15~euro per year), they take care for all the stuff saving you all the maintenance struggle and possible components failures like dead batteries, hail damage to panels, efficiency lose on panels.
This house is obviously a prototype used primarily for research and development; therefore, whether or not it is it is cost-effective today is irrelevant. Most new technologies aren't good enough or are too expensive initially, but some of them become good enough and affordable eventually.

that is cool! but how much money does it costs?
The owner said in an interview that his hous cost him 15M SEK which is around 1.49M $.
BUT he installed alot of the stuff himself so the real price will be higher for something like this if you just want to buy it.
@@Alex4nder1978 my Germany company is also doing this develop.
@@annioffical9767 May I ask which company that is? The only one I currently know of is HPS with their Picea system in Germany. But I have to be honest I never checked for other companys who do the same thing. 😅
cost ?
One assumes one means upfront/capital cost?
@@dariusseo480 As opposed to what, the monthly cost? Obviously, he wants to know how much it costs to build the system. The answer is obvious: the cost is prohibitively expensive for an ordinary consumer because this house is a prototype being used for research and development.
In the video the presenters purposely fail to mention the cost of the system apparently because the answer to, "How much does it cost at this time?" is probably something like, "If you have to ask how much it costs, you aren't wealthy enough to squander money on this for yourself at this time but if we get enough venture capital we can make it cheaper."
@@yekutielbenheshel354 one may not be able to afford upfront, capital costs but operations that use EV engines have been known to achieve something like a 60% savings, yes, in monthly operating coats. The issue is can one overcome the cost of capital too?
@@dariusseo480 I don't understand your gibberish. Please correspond coherently or not at all.
@@yekutielbenheshel354 real simple, do you buy cars planes and trains without the financing of a lender. Is that simple enough?
Now what they need to do is build an identical house, that is 100% electric, no H2, with geothermal HVAC system, and compare the costs. With just the solar, batteries, and inverters they are pushing $150k easy.
It would be far less costly to just have an over sized solar system, with battery back-up.
This just doesn't make sense in any sort of cost efficiency basis.
Assuming the fuel cells are roughly 50% efficient, the house is storing approximately 5MWh in compressed hydrogen. So if you wanted to replace that with, say, LiFePO4 batteries you're looking to spend over $1m. What would be interesting is how much the hydrogen system cost in the house.
Note that Gothenburg is almost 58 degrees North; the amount of solar energy available in winter will be negligible.
@@marksherborne391
Going with battery paired to a heat pump make sense because it can go 3-400% efficient and is not explosive
sorry guys you're missing the point. the network fee in sweden is over 200£ per month even when you only use fex 30-70£ worth of electricity so the yearly saving on being off grid is enormous! besides this the electricity cost is not fixed but follows market fluctuations and tends to only go up... so you are free with such a system! I will build one like this myself if i can afford it ;:)
It seems that hydrogen is used to replace some batteries. Hydrogen doesn't lose power like batteries and has much higher energy density than batteries.
@@lorenzoventura7701 that maybe so. But hydrogen blows up and not like any fossil fuel

Nice house, nice setup.. unfortunately, this is not a "real world" example for the sales pitch. It all sounds too good to be true in this example, and you know the philospohy behind that one !! I have been 100% behind hydrogen for many decades: there are some great resources shared and I hope this helps very many people, but if they are novices in the religion of hydrogen, they may soon find that the practicable, achievable, tangiable possibilites are so far out of thier financial/situational reach, that they may easily become depressed and
disilusioned. Going about it the same old same old, elitest, counter-productive ares about face way. All credit though to the companies bringing these first generation technologies into to domestic (elite domestic) market.
When Tesla first came out very few could afford it. The first Cell phone was for the rich and drug dealers here in California. Now you have Electric Hummers, audi, MBZEQS, Ford lightning. This house is a nice proof of concept to show what's possible. Better and cheaper systems will be made, just like battery technology.
Check out this cheaper home.

I essentially agree almost all of your points. I like hydrogen too. Nonetheless, the "sweet old man" is a deceitful ignoramus. I despise guys like him.
Hydrogen House built by Sweden,
Use hydrogen cylinder as regular gas cylinder😂 so what happened 😂😂😂
The common sense is only what is missing here !
Classic example of an engineering fail. Basic rules Keep It Simple Stupid. This is far from that
Why do they not store as a Hydride, MgH2 ???
