Imagine a second-life battery based storage container providing energy in all airports. Have them charged and then connect the plane to it while ground operations are in progress. One more CO² emitting device replaced with retired batteries. At Marny Energy we're confident we can supply the required power for a plane to work properly while on the ground!
