Large scale electrification of the energy and chemistry sectors is a crucial condition for the transition from a society based on fossil fuel to a sustainable society based on renewable building blocks. Electro-organic synthesis will be central to the approach to combine building blocks to organic molecules to form of 'electrofuels', as well as to use electricity to make 'electrochemicals'. Therefore, efficient electrochemical energy conversion and production of fuels and chemicals are important technologies for the future of sustainable energy.
