In this lecture, I will introduce DIFFER’s facilities for the characterization of materials for the energy transition. In the first part of the talk, will focus on facilities  and equipment that we have developed at DIFFER in recent years for diverse energy applications. I will illustrate what we can measure and which challenges are involved for these high tech instruments. In the second part of the talk, I will take you along our strategy and plans for the coming years and will focus in particular on what facilities are needed for designing and developing highly performing energy devices.
