Energetic particles (EPs) will play a central role in future burning plasma experiments, as they can strongly interact with the bulk plasma and drive magnetohydrodynamic (MHD) instabilities. For instance the fishbone instability is the result of an internal kink mode destabilized by EPs in tokamaks. This contribution describes applications and developments of the nonlinear extended MHD code JOREK, whose kinetic module is used to investigate the interaction between EPs and core MHD instabilities both in the linear and the nonlinear regime. The kinetic module uses a particle-in-cell technique and describes the EP distribution function with a full-f formulation. The results will also be compared to gyrokinetic simulations performed with the ORB5 code. Furthermore, the current work on implementing a model in JOREK that describes also the thermal ions kinetically is presented.
