Abstract

The present invention relates to methods for reducing metal oxides under reduced pressure and by using concentrated solar energy; to solar thermochemical reactors and systems adapted to such methods; to the use of such methods and reactors in the production of metals and metal containing compounds, and in performing thermochemical redox cycles for producing hydrogen and/or carbon monoxide and/or hydrocarbons (fuels) from water and/or carbon dioxide, in producing ammonia and in performing thermochemical redox cycles for separating oxygen from gases.
