First Claim
1. A process for generating electricity, comprising the steps of:
- a) providing a hydrogen fuel cell requiring gaseous hydrogen to generate electricity;
b) catalysing a hydration reaction of CO2 to produce a solution containing bicarbonate ions and hydrogen ions;
c) combining the hydrogen ions of step b) to form gaseous hydrogen; and
d) supplying the gaseous hydrogen obtained in step c) to the hydrogen fuel cell to generate electricity.

Abstract
The object of the invention is the coupling of a hydrogen fuel cell to an enzymatic process for the production of electricity and the transformation and sequestration of CO2. Gaseous CO2 emissions from processes such as hydrocarbon reforming are transformed into carbonate or bicarbonate ions and hydrogen ions by the enzymatic system in order to prevent their contribution to the greenhouse effect. The hydrogen ions resulting from the enzymatic process are recovered and combined in order to supply the hydrogen fuel cell. Finally, water, a by-product of the oxidizing reaction of the hydrogen fuel cell, is recovered and recycled back into the aqueous enzymatic system.
