 Abstract: Phase separating systems that are maintained away from thermodynamic equilibrium 
 via molecular processes represent a class of active systems, which we call \textit{ active emulsions}.
 These systems are driven by external energy input for example provided by an external fuel reservoir. 
 The external energy input gives rise to novel phenomena that are not present in passive systems.
 For instance, concentration gradients can spatially organise emulsions and cause novel droplet size distributions.
 Another example are active droplets that are subject to chemical reactions such that their nucleation and size can be controlled and they can spontaneously divide. 
 In this review we discuss the physics of phase separation and emulsions 
 and show how the concepts that governs such phenomena can be extended to capture the physics of active emulsions. 
 This physics is relevant to the spatial organisation of the biochemistry in living cells, for the development novel applications in chemical engineering and models for the origin of life.
