ICARE or GEER model once again is published and could serve as a basis for e.g. the global hydrogen market

System Dynamics Society's wiSDom blog published our model on the global energy transition: https://systemdynamics.org/consideos-insight-into-the-global-energy-transition-a-systems-perspective...
If someone needs to run simulations on hydrogen, copper, neodymium, .... we might join the task with our model.
