Valorising Waste H2 Header

Electrochemical processes, such as the industrial production of caustic soda and chlorine, use large quantities of electricity which contribute significantly to production costs, up to 70% in some cases. They also produce hydrogen as a waste product (see diagram), which is either combusted or vented to the atmosphere. Fuel cells offer a highly efficient method of utilising this hydrogen to produce electricity, offsetting much of a plant’s electrical demand whilst at the same time reducing emissions.

This information sheet explains the key benefits that fuel cells can offer in this application, the fuel cell types used in the application today, and case studies of a 40 kW AFC Energy installation in Germany and a 1 MW Nedstack installation in Belgium.
