Our mission is to develop digital solutions for tomorrow’s energy system. Our software tool SmartSim for gas quality tracking enables gas grid operators selective invoicing of customers when different gas qualities (natural gas, biogas, hydrogen) are injected into the grid. It has already been implemented and approved at more than 20 grid operators all over Europe. The software GasCalc allows precise prediction of all relevant natural gas properties (www.gascalc.com). SmartSim GmbH is a spin-off from E.ON and was founded in April 2018 by Peter Schley, Christian Fiebig, Andreas Hielscher and Stefan Rickelt.
