Claim 0:
1. A renewable methane production module comprising:
a water capture generator designed for directly capturing water from atmosphere to provide water in a liquid form, the water capture generator including an absorbent material designed to be exposed to atmosphere for directly absorbing water from the atmosphere onto the absorbent material;
an electrolyser operatively coupled to the water capture generator for receiving the liquid water, the electrolyser being effective in electrolysis of the liquid water to produce hydrogen;
a carbon dioxide extractor for extracting carbon dioxide from atmosphere, the carbon dioxide extractor being configured for directly capturing carbon dioxide from atmosphere using a metal-organic framework (MOF) capable of directly absorbing carbon dioxide from the atmosphere; and
an exothermic reactor operatively coupled to the electrolyser, said exothermic reactor (a) configured for reacting hydrogen from the electrolyser with carbon dioxide from the carbon dioxide extractor to produce renewable methane in a Sabatier reaction, and (b) operatively coupled to a heat exchanger designed to exchange heat derived from the production of renewable methane with the carbon dioxide extractor to heat the MOF of said extractor to release the absorbed carbon dioxide from the absorbent structure.
