We prove a finiteness theorem for the local l ≠  p-component of the \({\mathbb{Q}}_p\) -unipotent Albanese map for curves. As an application, we refine the non-abelian Selmer varieties arising in the study of global points and deduce thereby a new proof of Siegel’s theorem for affine curves over \({\mathbb{Q}}\) of genus one with Mordell–Weil rank at most one.
