The integration of renewable energy (RE) sources in the power system is a key strategy to reduce fossil fuel consumption and promote the transition towards a sustainable energy system. To this purpose, hydrogen as energy vector will be a key instrument for meeting the EU Green Deal objectives. In this context, solid oxide cells (SOCs) are promising electrochemical devices for the conversion of chemical energy into electrical energy and vice versa. Solid oxide cells devices are of great interest for efficient and clean power generation and for highly efficient conversion of electricity to hydrogen, fuels and chemicals using high temperature electrolysis.
