In Thailand, CNX Construction is developing four Phi Suea homes powered solar panels that will convert its excess energy into hydrogen that can be stored and reused. 

As the solar panels produce energy, the excess power will be directed to electrolyzers and produce hydrogen, which can be stored in a fuel cell system. Construction is nearing completion now while the energy system has entered the testing phase for the first three buildings.

When fully up and running, the system will reportedly be able to produce hydrogen at a maximum rate of 2,000 liters (440 gallons) every hour and will be able to store up to 90,000 liters (19,800 gallons). The daily demand for electricity is expected be around 200 kWh. The fuel cells will be able to produce 120 kWh at full storage, which should be adequate for nighttime use.
