Tata & MIT System To Use Sunlight To Split Water Into Hydrogen & Oxygen (video)
A criticism often leveled at solar energy is that it is not "base load". i.e. because it only generates electricity in daylight, without storage, it's not available 24/7. Storage is generally expensive &/or inefficient. Numerous schemes have been suggested, but have never reached production apart from for small applications. e.g. lead acid batteries for storage of solar for small communities.
In theory, solar electricity could be used to split water into hydrogen & oxygen. At night, the hydrogen & oxygen could be used directly (e.g. for heating or cooking) or to generate electricity.
In the item below, the system being developed generates hydrogen & oxygen directly from water with greater efficiency than photo voltaic systems.
