The energy transition has far-stretching implications for chemical companies. e-Refinery at TU Delft enables industry partners to start building the required technology capacity and human capital as soon as possible. Researchers in the e-Refinery initiative focus their research on the electrochemical conversion of sustainable electricity into fuels and chemical building blocks, from the molecular scale to large-scale system integration. Implementing e-Refinery will serve three important challenges that the society is facing: CO2 neutral Fuel, seasonal energy storage and a defossilized chemical industry.
