    Hi!
    Here's a question I've been thinking

    Is it any more efficient to power electrolysis of water for energy with solar panels instead of just using solar panels themselves for generating electricity?
    Instead of using the electric from the solar panels directly, would there be any benefit to use the solar panels to power an electrolysis setup and use the HHO for electricity generation?


    Thank you!

    Electrolysis of the water will result in lower total conversion efficiency of the sun's watts to electrical watts as opposed to using the solar panel output directly, but the benefit of the electrolysis is being able to store the energy for later use, as opposed to consuming it immediately. Another option besides electrolysis (at lower cost) would be storing the electrical energy in a battery, such as a lithium-polymer cell.

    Every step (between "source" and "output") introduces further losses in efficiency because no process in 100% efficient.
    But, as Devin-m stated, there may be other considerations.

    No - it is far less efficient, due to losses in the electrolysis rig and the fuel cell.

    However, it has been considered as a way to store solar energy for later use.

    If you convert it to fuel you can bottle it and ship it around the world... like to regions where solar energy is relatively poor.

    If you go another step by converting the hydrogen to methane (AKA "natural gas") it's readily consumed through existing infrastructure and ordinary engines.
