Real-space grids are a powerful alternative for the simulations of electrons systems. One of the main advantages of the approach is the flexibility and simplicity of working directly in real-space where the different field are directly discretized on a grid, combined with competitive numerical performance and a great potential for parallelization. This properties constitute a great advantage at the time of implementing and testing new physical models. In this article, based Based  on our experience with the Octopus code, in this article  we discuss how the real-space approach has allowed for the recent development of new ideas for the simulation of electronic systems. Among these application applications  are the modelling of quantum transport, photoemission, optimal  control of quantum systems, and the exact solution of the Schroedinger equation for low dimensional dimensionality  systems.
