Producing hydrogen from electricity, storing it and then turning it back into electricity and heat in a fuel cell?
The steady increase in the supply of fluctuating renewable electricity raises the essential question of how best to secure the supply of energy to industry. At present, reliable heat-controlled processes constitute the basis of industrial production, whereas fluctuating electrical process management will be called for in the future. Fuel cells, as continuous electrochemical processes, provide the basis for developing both new electricity storage technologies (power to power, power to gas) and production processes (power to substance) and for deploying them industrially.
These methods deliver electrical energy from energy-rich substances or they produce energy-rich substances as products from electrical energy and raw materials. This perspective has led to new developments worldwide, the marketing of which is to be promoted through development-related standardization.
The "Reverse Fuel Cells" working group within IEC/TC 105 "Fuel Cell Technologies" has developed a work programme that will be implemented over the coming years. The change in the process management makes it possible to use fuels to help guard against longer supply downtimes, such as calm periods, by increasing existing industrial energy storage capacity.
