A process for generating electricity from light hydrocarbons substantially in the absence of carbon dioxide emission, the process comprising the steps of:
- (i) contacting at an elevated temperature hydrocarbon gas with a catalyst to catalytically convert the hydrocarbon gas to hydrogen and solid carbon;
- (ii) separating and recovering the hydrogen generated in step a);
- (iii) using a first portion of recovered hydrogen in a fuel cell to generate electricity;
- and
- (iv) combusting a second portion of recovered hydrogen to generate elevated temperature in step a);
- wherein the catalyst comprises one or both of the following:
- (a) a calcined Fe-containing catalyst;
- or
- (b) a bimetallic MxNiy-type catalyst supported on a substrate.
