But for normal people this need to be scaled down. and be affordble, but that is the future

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.

Why do they not store as a Hydride, MgH2 ???

Classic example of an engineering fail. Basic rules Keep It Simple Stupid. This is far from that

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.

Climate change and the carbon footprint thing is a lie, it is a creation of British Petroleum, it's all created to steal money everyone on this earth.

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.

Until oil mafia find you adress

Hydrogen House built by Sweden,

Thanks

Gohenburg rocks!

could you tell me where is that hyrogen house address ，

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.

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.

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.

excellent, Many thanks for sharing some inspiration for Southern Africa

Thank you for effort 💖

Feeling like ordering one for all homes, have you had a chance to update an inventory of possible replacements as to save mostly space?

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🤚

The common sense is only what is missing here !

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.

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.

There are not enough raw materials to apply this everywhere

Good example of the past. However advancement in technology today may make this house use less separate features and more affordable.

that is cool! but how much money does it costs?

LA CE PREȚ AR AJUNGE CU TOTUL ?

Use hydrogen cylinder as regular gas cylinder😂 so what happened 😂😂😂

Great video spoilt by the excessively loud pornography music.

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.

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.

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.

Good show, few things are extra, would be interested to discuss implementation in a tropical country using solar, wind and Hydrogen only.

All thanks to Dr Alaho Olu on TH-cam who finally cured me from Herpes Simplex Virus type 1&2 and HPV

cost ?

Really useful video. Thanks for that. How can I get this presentation?

Immaculate installation and really environmentally friendly! Greetings from Spain.

The VPA-2 Solar System - Solar Power Fifth Generation

I love the attention to detail to find every spec of efficiency. However, the PLCs themselves are going to be well over £5000

Mike strizki hydrogen house usa. Wonderful workmanship

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.

Great film and idea to make it by David. Greetings from Chalmers and Sweden. Valery
