Hydrogen fueled stove for autarkic living

Cooking is one of the remaining challenges in autarkic living. In summer electric cooking from PV is well possible. Nevertheless, long term battery storage to cover the energy demand for electric cooking in winter is not feasible. A superior approach to seasonal PV energy storage is the production of hydrogen by water electrolysis and storage thereof in metal hydrides. With this approach no hydrogen loss is encountered during storage time, volumetric energy density is increased and storage capacity is decupled from power conversion potentially reducing storage cost. When considering hydrogen as energy carrier the possibility of direct conversion to heat by catalytic oxidation becomes practicable. To this accord a novel catalytic diffusion burner for hydrogen, based on highly porous silicon carbide (SiC) ceramicfoams, coated with platinum (Pt) as catalyst has been developed and integrated into a cooking stove.
