Germany is supposed to become climate-neutral by 2045. The federal govern-ment’s new climate protection law stipulates this. Greenhouse gas emissions are supposed to drop at 65 percent below their 1990 values by the year 2030. Many innovative ideas and solutions are needed to implement this ambitious plan. Together with their partners, research scientists at the Fraunhofer Institute for Factory Operation and Automation IFF are making a contribution in the RIGRID project: Its objective is to supply rural areas with power sustainably, cost-effectively and reliably.
