In the first phase of the energy project ZO.RRO (Zero Carbon Cross Energy System), Nordhausen University of Applied Sciences has developed a unique digital energy transition calculator as open source software. The result: an energy system model that can calculate transformation paths and scenarios for a climate-neutral energy supply. Using Thuringia as an example, it was shown how the goals of the Thuringian Climate Act can realistically be achieved using certain technologies.
The open source software can now also be used not only for other federal states, regions and municipalities, but also for energy suppliers and companies, and it supports them with scientifically based scenarios to define binding expansion targets and transformation paths. That is why, this development was awarded with the Thuringian Digital and Open Source Prize 2022 on 25 June 2022 by the Thuringian Ministry of Economy, Science and Digital Society. As such, the new ZO.RRO tool is already widely used.
In the ZO.RRO II state project, the energy flows and CO2 emissions are determined, analyzed and visualized for each of the practice partners by means of an energy system model. By step-by-step programming of scenarios, into which measurement data of the ZO.RRO measurement technology flow, it is individually calculated which technologies that enable a CO2-minimal energy supply. The goal is a realistic, cost-optimal system design to cover the energy demand of the given company at any time.
