IT systems and infrastructures for a CO2-free energy supply

IT systems can quickly and effectively evaluate complex relations. Therefore, their usage could also contribute to the reduction of CO
2
emissions in the complete energy system. Here, a concept for an overall IT ecosystem is presented which supports the minimization of CO
2
emissions. It includes the measurement of material flows by sensors, the storage of the collected data, the combination of IT systems and a supervision system. Furthermore, a CO
2
monitoring tool is presented which displays the current CO
2
emissions and can provide a 24-hour CO
2
emission prognosis. By including modern energy system approaches, like sector coupling, a more realistic consideration of CO
2
emissions is possible. The usage is designed on three separate layers. By data aggregation of the lower layers, given by industries and energy suppliers, action recommendations for reducing CO
2
emissions can be made by the supervision layer.
