Conversion of Renewable Energies for Storage
The Requirement: To create a fuel
» That can be stored and transported
» That can be converted to useful forms of energy
(electricity, mechanical)
» That does not pollute the environment
There is such a fuel.
It is called: Hydrogen

The Solution
![Page 10: Power for the 21st Century Innovation Energy Environment Fuel Cell Technology in Renewable Energy Hybrid Systems for Mobile / Stationary Applications and](https://reader035.vdocuments.mx/reader035/viewer/2022070412/56649d8b5503460f94a72dcd/html5/thumbnails/10.jpg)
Hydrogen allows storage of high amounts of energy at small volume to balance offer and demand during daytime and season
Clean energy carrier: No carbon emissions compared with fossils
Low space requirement compared with batteries
Low noise during energy conversion
Flexible use: Fuelling cars from home-made hydrogen possible
Why Hydrogen?
Hydrogen plays a significant role on the roadmap to a fully energy autonomous and sustainable building-concept
