Hydrogen production is a key element for the hydrogen economy.

Hydrogen production is one of the biggest problems for the hydrogen economy. Removing carbon from hydrocarbons is not very difficult. The idea is that the system uses an active carbon filter. That filter can remove carbon from the communal waste. 

But the problem is where the system puts that carbon. In one of the most futuristic versions, the pressure system could crystallize that carbon and make carbonite crystals called industrial diamonds. But that system requires energy. And energy is the biggest problem in producing commercial hydrogen. 

One of the things that can solve this problem is wind or any other clean energy that can use to split seawater electrolytically. The system also produces sodium and chorine. The hydrogen ions and chloride anions travel to different electrodes. 

And the sodium ion will stratify to the same electrode that produces hydrogen. This thing makes it possible to produce chlorine and sodium in the same factories that produce hydrogen. Also, those platforms can produce pure oxygen for many purposes. 

Energy islands offshore energy production. 

But then we can think about floating solar panels or floating platforms, there are solar panels and tubes with turbines. The idea is that when the tube is upward at the bottom of the sea or lake, the capillary effect pulls water through it. Then that water flow will rotate the generators. Those floating energy islands can offer free energy for people. The fact is that this energy can use to split water molecules. 

Or the system can drive it to the batteries or capacitor-based energy storage. If the system drives energy into the network through energy storage, that will act as a residual-current device. That protects the electric network from errors. And it stabilizes the tops and bottoms in energy use.  

When there are sunny or windy days. The system can produce energy for storage. And when the level of sunlight or wind is low, the system can deliver energy from those storages. In that case, I must say that if there are capillary tubes in some lakes they can produce electricity. Without the need to care about the weather.
