The energy revolution was already omnipresent before the decision was made to phase out nuclear power: Germany has been pushing ahead with a shift towards renewable energies and intends to be supplying most of its demand from these sources by 2050.

Wind turbine parks and particularly pumped-storage hydroelectric power stations require considerable space, however, and thus also destroy natural landscapes. Researchers at the Fraunhofer Institute for Wind Energy and Energy System Technology are tackling this problem by developing technology that will replace en-tire pumped-storage hydroelectric power plants as energy storage units: giant hollow concrete spheres are completely submerged in water. Excess energy is stored in them by pumping all the water out of them through outlet valves. When the inlet valves are later opened, water fl ows in and drives in-built turbines that generate electricity.

Living up to its reputation as an innovative solution provider and acting in its role as a mobility expert for heavy loads, RUD took up the challenge and was able to convince the researchers of the robustness of its VIP lifting equipment even when used under the most ad-verse environmental conditions.

After the initial experiments in Lake Constance with a sphere diameter of three metres, a sphere that is ten times larger is already being built. This will then be tested in the sea at a depth of 600 to 800 metres. RUD is looking forward to developing a solution for this too and is proud to be part of the energy revolution in this way.
