Startup Idea : Hydrogen battery for residential

Millions of solar panels are installed around the globe, but the efficiency of them is too low to even matter. The reason to this is, that solar panels generate electricity during the day when people are not home and does not use electricity. Therefore the electricity is sold for a very low rate to the electricity companies. Th companies don't wont the electricity and that is why they pay a very low rate. My solution is a battery that can charge the electricity generated by the solar panels during the day, and release it as people get home at night. My solution is based on electrolysis with water and hydrogen. For my idea I need two persons: 1. Chemist with hydrogen as their major2. Product developer or electro engineerI am a business engineer from Denmark who is also educated an electrician.
