I renamed the image but frankly you could make an effort to:
1) follow the instructions for downloading images

Re: The hydrogen house
Hello everybody
Since 2012, I have succeeded in making our old building (> 50 years old) positive energy (electricity, heating & water) (French-speaking Belgium)
I have the project to equip myself with an electrolyzer / hydrogen fuel cell couple.
Here are the details of the project and the questions (too long to repeat here):
http://www.retrouversonnord.be/projet_Hydrogene.doc
The originality of my project is to recover the residual heat of the couple (especially of the battery) and which corresponds to more than 50% of the losses
and thus be able to relieve the work of the heat pump while greatly reducing its consumption.
In this way, I hope that the 11.500 kWh produced annually (photovoltaic tracker) will be sufficient.
Thank you for your comments and suggestions,
Baudouin

Re: The hydrogen house
the product looks interesting (at least the commercial characteristics )
according to the pages the efficiency goes from 95% to 90% (with heat recovery)
and 97% for heat production alone
6-year return on investment and 25-year lifespan ... to see

Re: The hydrogen house
“Post-oil technologies are available,” the article begins.
Maybe but at what price? Because even in Scotsdalle (Arizona), covering your electricity consumption with PV, electrolysis, hydrogen storage and a fuel cell must be sweet! Particularly to cover winter needs, where even in Scotsdalle the days are shorter and the sun is lower.
There is no doubt that this is technically possible, even if I don't really know of any offer available today for micro-applications.
Edit: I had not yet seen the post by Baudouin Labrique, it seems that solutions are emerging.

In any case the idea of improving the COP of the heat pump by the losses of the fuel cell is interesting.
However, in your Word text, "Regarding electricity, we use the electricity distribution network as a 'battery' to 'store' the surplus, the use of quotes does not change the fact that it is bullshit (a "niche" in more correct terms!).
Have you calculated the storage volume of H2 that would be necessary to be effectively autonomous?

I await the precise calculations following the tests of the first machine which will be installed in Belgium soon at Ets Giacomini who will precisely market it then.

We agree and that I had included in the description.
That is why I count on the recovery of residual heat to reduce the consumption of the geothermal hauler pump and thus compensate for a large part of the 59%.
For the rest, I detailed solutions that will save more than 2000 kWh / year, which corresponds to almost 20%, then allowing the use of a hydrogen car (less than 10.000 km traveled per year ).
